Solar Thermal: It’s All About the Collector Panels

Solar America Solutions is not the only company in the U.S. offering solar thermal for space heat and hot water. But we are one of the leading players, as evidenced by the patent we obtained for our SunQuest 250™ solar thermal collector in 2015. Why should you care about the SunQuest 250™? Because when it comes to solar thermal, it is all about the collector panels.

In recognizing our patent achievement, patent counsel Victor Indiano remarked that he knew our collector panel was “a winner” the moment he saw it. He went on to explain that many of the technologies in our industry do not live up to manufacturer claims. Our collector panel is different. Not only does it do what we say it does but it sets the standard for all others to follow as well.

Spend Your Money Wisely

If you are thinking about a solar thermal installation for your commercial building, spend your money wisely. You can invest in an inferior system with substandard solar collector panels, or you can invest in a Solar America Solutions SunQuest 250™ system. Just remember this: it is all about the collector panels.

How important are panels? A recently completed study in Germany provides the answer. Researchers analyzed the total cost of solar thermal installation for process heat applications. And although the peripheral equipment used for process heat production is somewhat different from the equipment we use to produce hot water and space heat, the solar collector panels are the same.

Researchers discovered that the biggest single cost of solar thermal installations is that of obtaining collector panels. They further found that there were drastic swings between prices offered by providers. Those price swings accounted for the unreliable pricing structures for building new solar thermal processing plants.

On average, 34% of the cost of a typical solar thermal installation in Germany is consumed by collector panels. For systems in excess of 100 square meters, collector panels consume 43% of the budget while smaller projects dedicate roughly 29% to collector panels.

There is no hard data to make an accurate comparison between Germany and the U.S. However, our own experience suggests a comparable situation here. The largest cost of a solar thermal installation tends to be in the collector panels. That being the case, you might just as well invest in the best panels in the industry if you want to achieve the best results.

The Future of Renewable Energy

To date, Solar America Solutions has installed solar thermal systems for space heat and hot water at buildings ranging from state prisons to college dorms. Through combined efforts with our partners, we have helped improve an egg washing operation in Ohio and create a heated sand mass radiant heat solution in Wisconsin. Our system has been installed in large scale manufacturing processes, state and federal corrections facilities, universities, major resort hotels, etc. We have even provided free occupational training to help inmates learn a marketable skill in anticipation of their eventual release.

For us, solar thermal is more than just a means to a successful business. It is the future of renewable energy in America. Solar thermal is a highly efficient way to convert the sun’s powerful ultraviolet rays into usable heat thermal energy for generating hot water and space heat, all while creating ZERO carbon emissions.

Our patented SunQuest 250™ solar thermal collector is based on evacuated tube technology that minimizes heat loss. The collector material we use inside our tubes absorbs energy from ultraviolet rays, so collection continues even on cloudy and overcast days. Lastly, one of our 25-bulb collectors requires just 21 square feet of installation space.

When it comes to solar thermal, it’s all about the collector panels. Invest your money in the SunQuest 250™ collector panel from solar America solutions.

The UK Backs Off Plan to Drop Solar Thermal

Backers of solar thermal in the UK have spent the better part of the last six months lobbying their government to prevent solar thermal from being removed from the UK’s Renewable Heat Incentive (RHI) program. The program is similar to the various tax and credit programs local governments in the U.S. offer for renewable energy installations. UK authorities were planning to drop solar thermal from RHI in 2017 so that money being spent to promote it could be invested elsewhere.

The Solar Trade Association led a coalition of lobbyists to convince UK officials to change their plans. The Association began their efforts in earnest with government consultation this past March, bolstered by the support of business owners opposed to the plan.

london

The typical business owner installing solar thermal in the UK breaks even at about seven years with RHI incentives. In other words, it only takes about seven years for a solar thermal installation to pay for itself. Without RHI incentives, it could take three times as long. The Solar Trade Association and its army of lobbyists argued that eliminating solar thermal from the RHI would prompt business owners to avoid new installations.

Now that the UK government has agreed not to drop solar thermal, there are high hopes for significant expansion in the commercial market. The Solar Trade Association now expects to see the growth it was projecting prior to the March consultation, growth that could help the UK reach its target of 12% renewable heat by 2020.

The Government Incentive Question

Questions about whether government should subsidize solar thermal installations are not unique to the UK. We see the same kinds of things being wrestled with here. Only here, things are a bit more complicated due to the way things are regulated at the federal, state and local levels.

Energy credits are typically the domain of state governments in that utilities are regulated at the state level. However, it’s very common for counties and local municipalities to throw their own credits in as well. The question is always one of how much to spend on incentives and to whom those incentives should be offered.

Here at Solar America Solutions, we have proven that our patented SunQuest 250 solar thermal panel is so efficient and produces so much thermal energy, that systems we have installed have provided a return on investment of less than five years even without government subsidies. However, governments that commit funds to renewable energy demonstrate to the public their support of seeking replacement energy sources that do not rely on fossil fuels.

Solar Thermal in America

Solar America Solutions has been a leader in solar thermal technology since our inception. Here in America, the industry is more focused on commercial applications than residential, which is why our company concentrates on commercial buildings including prison facilities, healthcare facilities, office buildings, dormitories, hotels, and the like.

As solar thermal grows in this country, we are proud to be part of the industry. Our patented SunQuest 250™ solar thermal collector is the best of its type in the business, capable of providing up to 35,000 BTUs per hour per panel, across a ten-hour solar day. Combined with the right equipment and a well-designed installation, the SunQuest 250™ can provide nearly all the space heat and hot water a commercial building requires.

UK government and industry officials have come to realize how important solar thermal is to future renewable energy goals. That’s why they have changed course and are now agreeing to include solar thermal in their RHI program. We would do well to learn from their example. Solar thermal is just as important to the future of renewable energy in the U.S.

Canadian Project Reaches 100% Space Heating Milestone

Canadian officials embarked on an ambitious solar project in 2007 intended to test the limits of solar thermal for district heating purposes. What they have learned in nearly ten years of operation has led to significant improvements that allowed the project to reach the incredible milestone of providing 100% of the space heat required by the project’s 52 energy-efficient homes. While Solar America Solutions has historically focused on commercial applications for solar thermal, we are nonetheless impressed by this accomplishment and recognize the value of district heating as a very viable solution in a residential setting.

canada

The Drake Landing Solar Community outside of Calgary consists of 52 rather spacious homes utilizing solar thermal for both space heat and hot water. Heat is provided via a district heating model that collects and converts solar energy to heat energy at a central location and then piped to homes on its circulation loop. What is not needed immediately is stored in one of two borehole storage tanks for later use. Hot water is provided on a house-by-house basis through individual solar powered water heaters and gas supplementation.

If you were to see an overhead shot of the neighborhood, you would see each home with a solar collector panel array mounted to the garage. The energy from those panels benefits every member of the neighborhood through district heating and hot water.

Natural Resources Canada has said that the system provided 100% of the required space heat for the 2015-2016 heating season. That is impressive, to say the least. The neighborhood system was originally intended to achieve a solar fraction of about 93% per year, but improvements to the system have helped Natural Resources Canada achieve the 100% milestone.

Sufficient Heating with Less Electricity

Drake Landing officials are obviously pleased with the results as well. For them, it is all about providing district heating at the lowest possible cost. According to project officials, solar thermal district heating uses 8 to 10 times less electricity than traditional heat pumps, which is important in a region that has year-round heating needs. Even in the midst of summer, district heat is still required in the Drake Landing community.

Officials are confident that the results they achieved during the previous heating season are repeatable. Though they aren’t saying whether they will reach 100% again this year, they are confident that they will start seeing repeat seasons in the future.

What It Means to Us

Here at Solar America Solutions, the importance of Drake Landing’s milestone is not lost on us. We have always believed that the potential of solar thermal for space heating and hot water is greater than anyone knows, which is what has prompted us to design and build our patented SunQuest 250™ solar thermal collector.

Every day, we are hearing more stories about the success of solar thermal for both residential and commercial applications. This motivates us to continue developing our own technology for the benefit of our customers. The further we can push the solar thermal envelope, the better we will be at meeting the needs of a world changing before our eyes.

We believe solar thermal is the future of renewable energy at multiple levels. Solar thermal already represents one of the most efficient and effective ways of generating energy for hot water and space heat on a property-by-property basis, and there is no reason to believe its potential for more widespread applications is limited. It’s a matter of simply scaling up the technology for size.

Our hats are off to Drake Landing and the impressive performance of their solar thermal project. After ten years of developing reliable renewable energy, they have proven that solar thermal both works and is commercially viable.

Solar Thermal Proves Its Winter Mettle in India

One of the concerns people have about solar thermal as a means of providing effective space heat is its ability to produce during the winter months. In the U.S. Northeast, the upper plains, and certain parts of the Midwest, winter temperatures can easily dip below zero for extended amounts of time. Well, now we know that solar thermal can get the job done even in some pretty harsh conditions. Thanks to a test conducted in the mountains of northern India, solar thermal has proven its winter mettle.

The real-world test of the solar thermal system was conducted by the Indian Defense Institute of High Altitude Research (DIHAR) at a troop shelter built at Chang La, a mountain pass that stands more than 17,000 feet above sea level. Moreover, tests were conducted during the winter months to see how well the system would perform in providing adequate space heat.

india

Researchers set up the system to store solar heat during the daylight hours using a phase-change storage tank. The stored energy was then used to produce the heat necessary to keep the shelter warm overnight. Throughout the test period, the ambient temperature inside the 295-square foot shelter remained between 44 and 50° despite exterior temperatures that reached as cold as -22°.

Saving Oil and Diesel

DIHAR officials say there were some points during the test when a diesel generator had to be operated to compensate for temperatures below -22°. Those occurrences were mainly in the coldest months of January and February. Still, the evacuated tube design of the solar thermal system performed well because they rely on ultraviolet “A” (UVA) rays from the sun, not the warm infrared (IR) rays that are not effective in cold or cloudy conditions.

Under normal conditions, the troop shelter is kept warm with wood, diesel and paraffin oil burners. Heating the shelter in the dead of winter consumes hundreds of thousands of gallons of diesel and oil every year. Researchers estimate that using the solar thermal system overnight could save as much as 10 liters of paraffin oil per day for every system installed.

Solar Thermal Suitable for Winter Climates

The solar thermal industry is very pleased with the results achieved by the Indian study. The study proves that our technology is more than suitable for winter climates, even when temperatures dip well below freezing. If an evacuated tube system can generate sufficient heat to keep a Himalayan shelter at 50° despite outside temperatures of less than -20°, imagine how well it might work here in the U.S. where most winter environments are not nearly as harsh

The key to the success of the Indian test was the evacuated tube design of the solar collector panels. Evacuated tubes, which happens to be the same technology the patented SunQuest 250®™ solar thermal collector is based on, make for the most efficient collection and transfer of solar energy for both space heat and hot water.

Evacuated tubes are glass tubes with an enclosed absorption surface surrounded by a vacuum. That surface absorbs solar energy which is transferred to a thermal liquid to be then sent to a heat exchanger for heat extraction. Extracted heat is either used immediately for space heat or hot water or forwarded to a highly insulated storage tank for later use.

Solar thermal space heat built around evacuated tube solar collector panels has proven up to the task in harsh winter environments. It has worked so well that DIHAR plans to begin installing the systems in several hundred buildings. All being well, what they have learned will improve the technology worldwide. In the meantime, there are a lot of buildings here at home that would benefit from a solar thermal solution for space heat and hot water.

Can Solar Thermal Be Harnessed for Sports and Leisure?

One of the first projects involving the Solar America Solutions patented SunQuest 250®™ solar thermal collector was a system installed at a correctional facility in Indiana. The project was designed to save Indiana’s correction department a significant amount of money by providing space heat and hot water for a new cell block. Since then, we have installed systems in a number of other commercial buildings. Expanding beyond our usual scope, we are looking into projects in which solar thermal can be harnessed for the sports and leisure sector.

sports

According to a UK company known as Stokvis Energy Systems, there is considerable potential in sports and leisure. They estimate that as much as 30% of the total running costs of a typical UK sports and leisure facility is devoted to energy. And much of that energy goes to space heat and hot water. Stokvis is committed to introducing solar thermal to the UK sports and leisure sector.

The Potential of the Sun Is Extraordinary

In our worldwide push for renewable energy sources, it is surprising that more attention hasn’t been given to solar thermal. Indeed, ask a person on the street about his/her impressions of renewable energy and this individual will likely mention creating electricity from wind turbines and solar photovoltaic (PV) panels as the main contenders. What many people don’t know is that solar thermal is more efficient and cost-effective for a variety of needs, especially for space heat and hot water.

According to UK-based Modern Building Services (MBS), the surface of the sun boasts temperatures of nearly 10,000°F; temperatures at the core could be as high as 59 million degrees. MBS says that the amount of solar energy that reaches the earth in just 30 minutes is roughly equivalent to all the energy humanity consumes annually. That’s a lot of energy.

What makes solar thermal systems so attractive is that it is the most efficient way to harness solar energy that we know of. Take our very own patented SunQuest 250®™ solar thermal collector as an example. Now in its third generation, it is 96% efficient. That means there is very little energy waste when converting solar energy into usable heat energy by way of a thermal transfer liquid. Just one of our solar thermal collectors can produce up to 35,000 BTUs and output temperatures as high as 400495°F.

We’ve learned how to harness the tremendous power of the sun to eliminate the need for fossil fuels for producing hot water and space heating. And as our technology improves, we don’t doubt for a minute that the potential applications for solar thermal will only grow. That potential can easily be put to use for sports and leisure.

Your Sports Facility Could Benefit

Solar America Solutions focuses on solar thermal installations for commercial buildings. One of our systems is the ideal renewable solution for your sports and leisure facility whether you are building from the ground up or looking to upgrade or replace an existing system. And rest assured you don’t need an excessive amount of roof space to enjoy the benefits of solar thermal.

One of our solar collector panels requires just a 3′ x 7′ surface area for installation, yet it provides 88 ft.² of absorption space. In other words, we can produce a lot of heat energy in a very small area. By setting up the right number of panels and connecting them to the peripheral equipment we supply alongside our collectors, we can give you a highly efficient system that will pay for itself within 3 to 5 years. Now that’s how you generate energy savings for your facility.

Australian Scientists Reach Solar Thermal Record

Scientists at the Australian National University have set a new record for solar thermal efficiency and in so doing have set the bar for future solar thermal development. According to various news outlets, the researchers were able to achieve 97% efficiency in converting solar energy into steam power. Earlier this year, the same researchers achieved a 34.5% efficiency in converting solar energy directly into electricity.

The Australian National University is well known for its excellent work in the field of solar energy, so few were surprised by their most recent accomplishment. That’s not to say there was no skepticism during the development of the project. In fact, some of the researchers were skeptical that the solar collector panel used to set the record would actually meet the projections engineers made when designing. But all turned out well in the end.

In this particular setup, the scientists used a giant, dish-shaped reflector to concentrate the sun’s energy on a high-powered collector unit, which heated up water and created steam to power an electric generator. Researchers attribute their high efficiency to the design of the dish reflector.

australia

Why This Is Important

What the researchers in Australia have done is essentially the same thing we do at Solar America Solutions – at least in principle. The two main differences are the fact that they are dealing with large scale power generation meant to replace coal-fired and natural gas plants while we focus on rooftop installations for hot water, industrial process water, and space heat, and the fact that they are using a giant dish where our patented SunQuest 250®™ solar thermal collectors have an exceptionally small footprint.

What we share is the vision to use powerful solar energy to generate thermal energy that can be used for any number of purposes. This is why the Australian project is so important. It proves that solar thermal is incredibly efficient when harnessed in the right way and using the right equipment and strategies. Efficiency is indeed its greatest asset.

When you convert solar energy directly into electricity, there are some inherent limitations in both conversion and application. So while the 34.5% efficiency achievement earlier this year (2016) is impressive, it pales in significance when compared to the 96% efficiency we have achieved with solar thermal. When you are converting solar energy into commercial levels of thermal energy, the possibilities are nearly endless.

Hot Water, and Space and Process Heat

Australian researchers are looking at high-capacity power generation using solar thermal. Here at Solar America Solutions, we focus on commercial applications that provide hot water, space heat, and heated industrial process water. We are helping our customers save money by reducing the amount of outside energy they have to purchase to meet their needs. And we’re doing it with our patented SunQuest 250®™ solar thermal collector that is among the most efficient evacuated tube collectors on the market.

Where hot water and space heat are the focus, Solar America Solutions installations are perfect for hotels, office buildings, dormitories, government buildings, hospitals, educational institutions, and more. As for process heat, there are almost no limits. Wherever steam or hot water is used to drive industrial equipment or processes, solar thermal can be deployed. One of our earliest installations was at a poultry farm that required process heat and hot water for egg washing.

The future of solar thermal looks very bright thanks to the ongoing efforts of researchers and product developers. We look forward to seeing what the Australian researchers come up with next, even as we continue to develop our solar thermal technology here in America. If 97% efficiency is possible, how much closer can we get to 100%?

Technology Just Keeps Making Solar Thermal Better

Solar America Solutions is focused on providing space heat and hot water solutions for commercial buildings. Our patented SunQuest 250®™solar thermal collectors are the perfect collector panels for commercial applications. Still, that does not stop us from paying close attention to industry news in order to stay abreast of what is happening across the entire industry. For example, a Spanish company has figured out a way to incorporate solar thermal with slate roofing tiles for residential purposes.

According to TreeHugger, a company by the name of Cupa Pizarras has developed a new solar thermal system that utilizes slate roofing tiles along with collector plates and storage batteries that can supply a household with hot water, space heat, and even supplemental heat for swimming pools. While the idea is far from being adopted on a wide scale for residential purposes, it holds a lot of potential.

SunQuest250

How the System Works

Natural slate has been used as a roofing material for centuries. It is extremely durable, very attractive, and does an excellent job of absorbing heat. Homes with slate roofs tend to stay cooler in summer and warmer in the winter because of the thermodynamic properties of the material. Those properties are what made engineers at Cupa Pizarras decide to use slate for their new solar thermal system.

In a typical installation, a roof is first covered by collector plates, which are themselves connected to a system consisting of storage batteries and heat exchangers. The collector plates are then covered with slate roofing tiles. As energy from the sun warms the tiles, the plates underneath collect the heat and transfer it to the storage units.

Heat exchangers within the system take that heat energy and use it for other purposes. In some installations, heat goes directly from the roof to the swimming pool during the summer months and is redirected indoors for space heat during the winter.

Solar Thermal Just Works

So what is it about this idea that excites us so much given that we do not do residential applications? In one word, potential. Every time a new technology like this is developed, it is further evidence that proves solar thermal just works. The concept is so incredibly simple: heat energy from the sun is collected and transferred to solar collector panels and specially designed storage units. That heat energy can then be used to do virtually anything we might have used fossil fuels for in the past.

For example, one of our first installations involved a rooftop set-up at an USA-based correctional facility’s inmate housing unit. We were able to supply space heat and hot water for that facility by simply taking advantage of what the sun naturally offers. The state corrections department was so pleased with the installation that they contracted with Solar America Solutions for additional installations.

The advantage of solar thermal over other kinds of renewable energy use is efficiency. Our patented SunQuest 250®™ solar thermal collector is a perfect example of that efficiency. Because it is based on a highly efficient evacuated tube design, there is very little heat loss between collection and transfer. Nearly all of the energy our panel collects from the sun goes right into the system.

There is no way to tell whether Cupa Pizarras’ solar thermal solution will be widely adopted across Europe. But we can say that ideas like theirs are creating the technologies that are leading solar thermal forward. With every new idea, there is more evidence that solar thermal is one of the best and most promising technologies for sustainable energy development.

Solar Thermal for Space Heat and Air-Conditioning?

We are intimately familiar with solar thermal energy being used to create space heat and hot water. In fact, our patented SunQuest 250®™ solar thermal collector is one of the best tools on the market for designing solar thermal systems that pay for themselves in short order. But what about using solar thermal for air-conditioning? It’s possible, as evidenced by a brand-new project now underway in Nicaragua.

A report from Sun & Wind Energy magazine claims that a hospital in Managua, Nicaragua has ordered nearly $4.5 million in equipment and services from an Austrian company contracted to install a solar thermal plant on hospital grounds that will provide hot water and energy for air-conditioning. The project is being funded via a soft loan put together by a number of international partners. The United Nations Industrial Development Organization and National Cleaner Production Centre of Nicaragua are also involved in the development of the project.

SunQuest250

The target of the project is Hospital Militar Dr. Alejandro Dávila Bolaños, the largest hospital in Nicaragua with 400 beds. The ultramodern facility was opened in 2015 in Nicaragua’s capital with built-in plans to make it as energy efficient as possible as new technologies became available. Adding the solar thermal plant will be the first major upgrade to the hospital since it opened.

A Major Rooftop Installation

Solid is the Austrian company that has obtained the contract to install the system in Nicaragua. Plans call for a solar thermal plant with 4,450 m² of collector space on the roof of the hospital. If all goes according to plans, the completed installation will provide all of the hot water needed throughout the facility while also contributing significantly to air conditioning.

Solid may have won the contract in part because of their reputation and experience. They have been part of more than 300 projects globally, and their reputation for successful implementation of solar thermal technology most definitely precedes them. Project officials believe the Nicaraguan installation will not only save the hospital money, but it will also reduce its emissions by up to 1,100 tons of CO2 annually.

Adapting Solar Thermal to Air-Conditioning

The idea of using solar thermal as a power source for air-conditioning is not something we talk about a lot in this country. Applications here are mainly for space heat and hot water – primarily because the heat generated by solar thermal systems is easily transferable for these applications. However, adapting solar thermal for air-conditioning is no harder than adapting it to process heat.

For example, let’s say we designed a rooftop installation consisting of SunQuest 250™ solar thermal collectors, thermal heat exchanger units, and storage tanks. All of the thermal energy produced by the system could be transferred to space heating equipment or water heaters in a standard installation. But it could also be used to generate energy that would power air conditioners.

We are not privy to the details necessary to describe exactly what the plans are in Nicaragua, but we cannot imagine the system would be too complicated. Solar thermal energy production is flexible enough that it can be used in a wide variety of applications. Providing power for air-conditioning is just one of them and both adsorption and absorption chillers that convert heat to commercial air conditioning have been in use for many years. We would like to see solar thermal collectors being used as the primary heat source for that application on a more wide-spread basis.

We look forward to seeing how the Nicaragua project works out. According to Sun & Wind Energy, similar projects funded by international soft loans are planned for other parts of the developing world as well. Right now is a great time to be part of the emerging solar thermal industry.

3 Russian Airports Going Solar Thermal

We are always looking for new ideas for implementing solar thermal technology capable of producing adequate space heat and hot water. So we were intrigued to learn that three airports in Russia will be fitted with solar thermal systems in the very near future. The Russian project is being headed up by Basel Aero, a company that operates multiple airports throughout the country.

Solar Thermal World reports that Basel Aero installed a similar system at the Sochi airport just prior to the 2014 Winter Olympics. Apparently, the installation was successful enough that the company now plans additional installations at three airports near the Black Sea.

The Sochi airport was furnished with 132 solar collector panels provided by a German manufacturer. The panels created an estimated 304 m² of additional collector space that combined with existing collectors to create a system that can provide as much as 85% of the airport’s hot water during the summer and 25% in the winter.

SunQuest 250

Thus far, Basel Aero has not said how big the solar projects for the other three airports will be. But we know from personal experience that the right kind of design and implementation can have a very significant impact on the amount of energy used to generate hot water and space heat. If they do the right things, those airports will notice a big difference right away.

Plenty of Commercial Applications

We are always excited to hear about projects like the Russian airport project. Being experts in the field of solar thermal collection, we know what kind of potential this technology holds, both now and for the future. We also know that there are plenty of commercial applications that would benefit from highly efficient solar thermal energy production.

Here in the U.S., solar thermal installations for commercial applications tend to focus on the following areas:

  • Space Heat – Solar thermal collector units convert sun energy into heat which can then be transferred through an interior forced air or hot water heating system to keep buildings warm. A properly designed system is capable of supplying all the space heat a commercial building would need. The most efficient space heating system is radiant floor heat that circulates water heated by solar through PEX tubes in the concrete floor slab.
  • Domestic Hot Water – Solar thermal technology can also produce a significant amount of hot water very quickly and efficiently. That water can be used for lavatory purposes, kitchen purposes, or to power industrial processes. Thermal transfer fluid is circulated from the solar panels through heat exchangers that in turn transfer the heat to a boiler or hot water heater, reducing the amount of fuel needed to achieve target temperatures.
  • Industrial Process Heat – One of the more exciting areas that seem to be growing right now is solar thermal process heat. By using energy from the sun, we can generate heat that that eliminates or significantly reduces fossil fuel generated heat used in industrial processes.

There really are few limits to what we can accomplish with solar thermal for space heating and hot water. And as the technology improves, new ways of using it will be developed. Already we are seeing exciting advances in storage capacity that will eventually make it more practical to utilize solar thermal generated energy around the clock.

At Solar America Solutions, we are especially proud of our patented SunQuest 250® solar thermal collector, now in its 4th generation. The SunQuest 250® is arguably the most efficient solar thermal collector panel on the market capable of output temperatures in excess of 400°F and generation of up to 35,000 BTUs per hour. It also has a limited footprint of just 3′ x 7′, making it possible to get an awful lot out of a relatively small rooftop installation.

We hope the Russian project goes as well as engineers anticipate. If it does, they may motivate airports here in the U.S. to look more seriously at solar thermal. We have plenty of collector panels to accommodate any new projects.
