About Us

solar for tomorrow
Cool Earth Solar develops and builds solar power plants that are clean, renewable, and good for the planet!

We accomplish this in two ways.

Solar Power Plants

We install solar at commercial and industrial sites, which are ideally suited for solar given their large energy use and expansive roofs. We also develop large ground mount solar power plants at farms/ranches or for connection to the Utility Grid. Please see our project page for more information!

Our CPV Product

We patented a new CPV solar technology, which is reshaping solar, literally and philosophically. While the development of our unique concentrated-photovoltaic (CPV) technology is currently on hold, the promise looks bright for solar.

what we do

Solar Services

that our customers love
We provide a full turnkey solar project for our customers. We perform a complete package of project services, including site survey, financial analysis, engineering and design, permitting, procurement, construction, utility interconnection, start-up and commissioning, plant monitoring, and on-going operation and maintenance.

Equipment

We only use the best solar equipment available on the market for our solar projects. We proudly use Solar Frontier and SunPower solar modules.

Engineering and Design

All engineering and design services are performed by professional licensed engineers. Electrical Engineering is at the heart of our solar power plants, and it is performed 100% by the Cool Earth team.

Quality Construction

We take pride in our construction projects. Quality construction work delivers a solar plant that performs well and lasts for over 25 years. All construction work is performed by the Cool Earth team of professionals.

Monitoring and O&M

Once a significant investment has been made to install a solar plant, it is important to monitor it's performance and validate the significant financial benefits. Proper operation and maintenance insures reliable production and long life of a solar plant.

cool facts about solar

see what we have developed

CPV Product

renewable. clean. efficient.
Our cool technology is "reshaping solar energy" in a very literal way: Most of today's solar energy systems take the form of flat panels or heavy mirrors or metal boxes-with-lenses and require significant amounts of heavy, expensive materials. Our inflated solar concentrators, on the other hand, are primarily made of inexpensive and free materials. This design approach radically reduces material requirements as well cost and time.

Our Solar Concentrator

At the end of 2016, we placed on hold the development of our solar concentrator product. While this unique solar technology is proven and robust, it is currently not able to economically compete with low-cost standard solar panels.

Highlights of our Solar Concentrator -
Solar Concentrators focus the Sun. Our inflated, tube-shaped concentrators are key to Cool Earth's innovative design. Each 3 foot diameter concentrator is made of plastic film - similar to that used commercially for packaging and shipping. A single solar cell in our concentrator generates up to 30 times more electricity.

The inflated structure is naturally strong—strong enough to support a person's weight—and aerodynamically stable, able to withstand high wind speeds. The inflated tube protects the PV cell and receiver from the environment, including rain and snow, as well as insects and dirt. Each inflated concentrator includes, in addition to the solar cell receiver, a small air pump for maintaining air pressure and a simple heat sink to handle the concentrated energy from the sun. The concentrators are so light and aerodynamic that they require a equally light-weight and inexpensive supporting structure and solar tracker. The resulting system uses a minimum amount of material, has a small footprint, and causes the least disruption to the natural environment of any solar power plant.

All in all, a simple, elegant and cool solution.


FAQ

Our system works like a conventional concentrated photovoltaic cell (CPV) system, but we take an unconventional approach to forming our ultralight optics and tracking the sun. Instead of using rigid aluminum or glass structures to focus light, we use very thin plastic films. And, instead of using ribs, trusswork, or material heft to maintain the optic concentrator shape, we use active inflation of air. Our concentrators are firmly attached to our own proprietary tracking system to track the daily and seasonal passage of the Sun.
Serendipitously, inflation air allows us to make an effective concentrator from nothing but thin plastic films. The inflated structure is lightweight, strong enough to survive high winds, and designed so the concentrator can produce electricity in winds up to 40 mph. We optimize the optical properties of the concentrator by actively controlling its inflation.
