Solar Thermal Perfect Choice for Correctional Facilities

Solar America Solutions is proud to have worked with corrections officials  across the country to install solar thermal solutions in various correctional facilities. Our installations have made it possible for corrections departments to save money on their energy bills by harnessing solar energy to provide space heating and hot water. In short, solar thermal is a perfect renewable energy option for correctional facilities.

What we have accomplished is not isolated only to the United States for that matter. Armenia offers an excellent case in point. A recent press release from Armenia’s justice ministry reveals that solar thermal installations have been deployed at seven different correctional facilities in the Eastern European nation.

Cell House

Detailed information about the installations wasn’t made available, but justice ministry officials say that they should save an average of 50% per institution as a result of deploying solar thermal. Along with their report on the installation, Armen Press published a couple of pictures showing solar thermal collector panels installed in rows outside of one of the correctional facilities.

The pictures show four rows of five collector panels each. Though we cannot accurately say what the capacity of each panel is, what we have seen in the pictures looks to be fairly typical for the industry. There is also an image showing the interior mechanics deployed to convert solar energy into space heat and hot water.

Correctional Facilities Offer Great Environment

Solar America Solutions offers solar thermal installations for all kinds of commercial buildings, including office buildings, dormitories, hospitals, and so on. We are especially pleased to be able to work with correctional facilities because they offer an optimal environment to showcase the potential of solar thermal.

By their nature, correctional facilities contain a lot of wide-open spaces that have to be accommodating to the needs of those institutions while still being efficient. Furthermore, the mechanics required to provide space heat and hot water have to fit in confined spaces and be relatively easy to service. Solar thermal provides everything correctional facilities need in a package that generates significant energy savings over time.

Using our own installations as an example, we fitted a 200-bed cell block at Wabash Valley Correctional Institution in Carlisle, Indiana with 15 of our patented SunQuest 250™ solar thermal collectors and the additional equipment necessary to utilize them. Our installation now supplements the hot water and space heat required by the cell block. Our Ohio project is even more ambitious.

In Chillicothe, Ohio we outfitted eight 200-bed cell blocks with 400 patented SunQuest 250™ solar thermal collectors for space heat and hot water. Corrections officials have been extremely pleased with the results of our equipment and installation.

Efficiency and Production

The secret to effective solar thermal is twofold: efficiency and production. Beginning with efficiency, it is fair to say that there isn’t a single energy technology on the planet capable of 100% efficiency. But solar thermal utilizing evacuated collector tubes is very close. Evacuated tubes suffer very little heat loss in the short amount of time it takes to convert solar energy into heat. Our own collector panels are based on an evacuated tube design.

As far as production is concerned, a single Solar America Solutions collector panel can produce up to 35,000 BTUs per hour in a package with a footprint of just 3′ x 7′. Within that small area, we can get just about 88 ft.² of absorption space using 25 evacuated tubes. Our technology has proven to be the perfect choice for correctional institutions.

Solar Thermal Is a Process Heat Machine in Mexico and Chile

One of the first installations we ever worked on at Solar America Solutions involved fitting a poultry farm with a solar collector panel array and peripheral equipment to be used to power a second egg washing machine for their operations. Though that installation was technically for hot water only, you could make the case that we were providing process heat. Since then, we have worked on a number of projects directly involving process heat.

Given our involvement in solar thermal for commercial applications, you can understand how pleased we were to learn of a successful project in Mexico involving solar thermal process heat from mining operations. Yes, solar thermal technology is not limited exclusively to generating space heat and hot water for commercial buildings. It has many more applications limited only by the imagination of designers and engineers.

SunQuest 250

The Mexican project, which was based on a similar project installed in Chile in 2013, provides process heat for copper mining. The project consists of 39,300 m² of solar collector space and a 660 m³ storage tank. Installation was completed in early September. Project officials expect the installation to provide nearly all the process heat needed by the mine.

Learning from the Previous Example

Installation at the La Parreña mine in central Mexico was completed in partnership with the Gabriela Mistral mine in Chile. That earlier project was completed in 2013 and has since produced some 142,000 MWh of process heat for mining operations. However, there is a distinct difference between the two. The project in Chile is large enough to be considered an independent Energy Service Company, requiring it to be managed by a third-party partner. The Mexican installation is far smaller. The mine operators themselves can manage it.

Getting back to the solar thermal installation in Chile, it operates at a near break-even pace. In other words, the 142,000 MWh produced by the installation is almost identical to the amount of energy the mine has used over its 35 months of operation. What goes into the system goes out nearly entirely. It should also be noted that the plant generates a minimum of 80% of its own power at any given time. They have to if they want to avoid government fines.

How It All Works

The solar thermal technology deployed at the mines in Mexico and Chile is based on the same principle we use here at Solar America Solutions. Solar energy is captured by a collector panel that immediately converts it to heat energy and transfers it to a thermal liquid. That thermal liquid is then circulated through a heat exchanger before going back to the collector panels.

Heat from the exchanger can then be distributed in any number of ways. For the mining operations, it’s used mostly for electrolytic refining. In other industrial applications, it could be used to wash down equipment or parts, concentrate liquids, dry materials, or even wash eggs as demonstrated by our poultry farm project.

The potential of solar thermal is really limited only to space constraints. For the typical commercial office building, a rather small number of patented SunQuest 250™ solar thermal collectors installed on the roof would be sufficient for hot water and space heat. More area would obviously be required for industrial applications requiring space heat, water, and process heat.

For more information about solar thermal technology or our patented SunQuest 250™ solar thermal collector, please feel free to contact us anytime. We believe the future of renewable energy resides in solar thermal, and we want to get you on board right away.

Simplicity Is Key to Solar Thermal Installation in Denmark

As a leading player in America’s solar thermal industry, we have heard all the arguments against renewable energy. The sun doesn’t always shine, the wind doesn’t always blow, and there is no way to depend on renewable sources to the same degree we can depend on fossil fuels. Well, officials in Marstal, Denmark have heard the same criticisms. That hasn’t stopped them from generating more than half of the heat required by a town of 2,300 via solar thermal.

Marstal is just one of a small number of communities occupying space on Aero Island off the southern coast of Denmark. It is a community that has long lived according to the dictates of the sea. It is a community that has long depended on nature to supply its most basic needs. So when they decided to embark on a solar thermal project to provide district heating, they were determined to make it work despite the region’s reputation for frigid weather. And work it does.

denmark

On the outside of town is a field with more area than six football fields, filled with solar thermal collector panels. Those panels are connected to a network of underground pipes through which flows water used to provide central district heating. The panels collect solar energy, then transfer it to a thermal liquid that is circulated through a heat exchanger. The extracted heat is then transferred to the water circulating through the system.

Year-Round Space Heat

So far you haven’t read anything that would suggest this installation is unusual. Still, you might be wondering how Marstal manages to generate 55% of its heat in an environment that gets limited sunshine during the winter months. They deployed a simple solution that has proven very effective. The Marstal heating project does not rely on anything other than an insulated, underground tank that holds water heated by solar thermal panels.

That’s right; something as simple as burying an insulated tank stores enough heated water to provide more than half of the space heat the town needs year-round. Obviously, it would be better to have a storage solution that could provide 100% of the heat, but that solution is not yet available. In the meantime, a system that provides 55% of the heat is remarkable. Even more impressive is the fact that it puts no additional strain on Denmark’s electrical system.

Denmark is a nation in which roughly 60% of the structures are connected to district heating. This is motivation for Danish officials to figure out how to provide cost-effective centralized heat without having to depend on fossil fuels. They have found that solution in solar thermal.

If They Can Do It in Denmark

It’s not unusual for us to hear that solar thermal is impractical for year-round space heat and hot water. We beg to differ. What many people don’t know is that our patented SunQuest 250®™ solar thermal collector doesn’t need direct sunlight in order to be effective. That’s why it generates energy even in the dead of winter.

Our solar collector panel utilizes evacuated tube technology along with an absorption material that captures ultraviolet energy instead of direct sunlight. That means our collector panel is absorbing solar energy even on cloudy and overcast days. With a properly designed system including efficient storage, an installation based on our patented SunQuest 250®™ solar thermal collectors can provide virtually all the hot water and space heat for your commercial building. If they can do it in Denmark on such a large-scale, we can certainly do it for your building as well.

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.

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.

Canada

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.

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.

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.

Nicaragua Says Yes to Solar Thermal Air Conditioning

When you think solar thermal, you typically think about space heating and hot water. So what would you say if we told you about a project in Nicaragua in which solar thermal will be used for air conditioning? Indeed, Nicaragua’s largest hospital complex just finalized an agreement this past September that will result in the installation of a monstrous 14,000+ square foot system to provide hot water and subsidize air conditioning.

The hospital is a 400-bed complex that broke ground in 2015. Some two years after the fact, hospital operators will be able to flip the switch on the new solar thermal system and immediately start saving a ton of money. They will spend upwards of $4 million on the system; the total building project is estimated to eventually cost $125 million.

managua

Liquefied Gas Savings

Designers have created a system that will use energy from the solar thermal installation to provide nearly 100% of the hospital’s hot water and up to 40% of the air-conditioning. The hot water would normally be supplied by liquefied gas, which can be very expensive in Nicaragua, leading engineers to focus mainly on the hot water solution. As for the air-conditioning, solar thermal will supplement an existing electrical system.

They expect excess energy not consumed by hot water needs to be redirected in a way that reduces the load on the electric compression chillers that will handle the bulk of the air-conditioning. At peak efficiency, engineers expect solar thermal can contribute to between 30% and 40% of the energy needed.

To make solar thermal usable for air-conditioning, heat energy has to be used to generate the electricity compressors and chillers need to operate. One way to do that is through steam. However, officials in Nicaragua say that steam is the one thing not being replaced by solar thermal. Exactly how engineers intend to utilize the solar thermal installation is not known yet, but they will likely direct excess heat energy into an adsorption chiller system, much like a propane refrigerator uses.

The Potential Is Huge

At Solar America Solutions, we are always excited to hear about projects like this one. It shows us that the potential for solar thermal is enormous if engineers just put their minds to coming up with new ways to use it. A few years back, we published a blog post about a group of enterprising college students who developed an ingenious way to use solar thermal for air-conditioning without generating electricity. These are the kinds of ideas that are driving the technology forward.

Meanwhile, solar thermal is being used around the world to provide heat, hot water – and, yes even air-conditioning – in the largest of commercial buildings. Property owners are quickly waking up to the fact that solar thermal is incredibly efficient and cost-effective. Furthermore, a system utilizing evacuated tube collector panels is usable for nearly any kind of installation thanks to its high heat output with a remarkably small footprint.

Solar America Solutions’ patented SunQuest 250®™ solar thermal collectors are the most efficient collectors in the industry. With just a very small footprint required on a rooftop or land area, one of our solar thermal solutions can generate as much as 65% of the energy needed for your building’s hot water and space heat.Over the years, we have installed our systems in prison cell blocks, university dorms, and even a Midwest poultry operation.

Hospital officials in Nicaragua are impressed enough with the benefits of solar thermal that they’re willing to spend $4 million on it. They are doing it because they know it will work. So what’s stopping you?

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.

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.
