solar for today

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.

Commercial Solar

We install solar at commercial and industrial sites, which are ideally suited for solar given their large energy use and expansive roofs and property. 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!

Residential Solar

We build solar projects for homeowners and residential properties! Please check out our project gallery below to see some of our recent projects. We can build one for you!

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.


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.
