Capitol Solar Energy makes ecology and economy compatible goals. We propose solar solutions that are efficient, competitive, and reliable, to maximize the benefits for our customers.

We are a friendly company that delivers real value to our clients, by keeping operating expenses low, designing premier-quality systems, using the most cost effective panels available, and drawing from 28 years of experience in systems design, installation and maintenance.As a small company Capitol Solar has the flexibility to truly serve its customers and avoid the "one size fits all" marketing approach of bigger corporations.
The starting point for using solar thermal energy is to heat domestic hot water, as it is used year-round. Solar panels are usually mounted on the roof while a small storage tank is installed in the basement. Other options exist if necessary or desirable. Usually 2 to 4 panels and 80 to 160 gallons of stored hot water compose a system.
25 years of priceless experience and expertise. Drain-back systems installed by Capitol Solar Energy require very little maintenance. However, Capitol Solar Energy has been servicing solar hot water systems installed by other companies since 1985. From Glycol to oil or water systems, from drain-down to drain-back systems, we know the ins and outs of your specific system.
Solar power is a renewable resource. You solar energy won't contribute to resource scarcity for your children and their children. Buying a solar system is like buying 50 years of energy at a fixed price, hedging your risk of rising energy prices. The more energy prices go up, the more you smile. Solar panels come with a 10-year warranty.
Now available in Colorado at wholesale and dealer prices, the Solene\Corona SLCO-40 panel is a high quality panel with both flush and tilt mount factory hardware. The 4' x 10' Corona has the highest energy output of any panel less than 40 square feet. We encourage you to compare panel performance ratings and pricing.

My husband and I are very pleased that we chose Capitol Solar Energy Company LLC to handle the removal and replacement of our solar panels, so our hail damaged roof could be replaced. The workers did an excellent job. Our dealings with Mr. Laurent were completed in a timely and professional manner. We are happy that they did not charge a penny more than their original estimate. Thank you for a job well done. Ida and Joseph Lash

Phenomenal experience. Laurent was timely in getting back to us, working with us on pricing, and even dissuaded us from upgrades that wouldn't make sense for our system. Their master plumber, Keith, understood our complex, dated system within 5 minutes after his arrival and diagnosed our issue in less time than that. He provided clear, concise explanations, offered efficient solutions and next-level possibilities, and finished the job in well under the time we had expected. So pleased with this group. Will definitely work with them again.

As a high volume roofing company, we have constant needs for efficient solar panel and replacement. Laurent and his team have always given us accurate dates and followed through for both us and our mutual customers. Great team and great follow through, which is tough to find in the residential solar market.

Capitol Solar installed and serviced the solar hot water and in-floor radiant heat in our Carbondale home. The system was professionally installed and worked well. I would recommend Capitol Solar to anyone considering this type of setup.

Terrible customer experience. They came out and took off the panels immediately so the roofing contractor could get his money, but they took 3+ months to come back and finish the job, which cost me $170/mo. Then they had the audacity to call and complain because they weren't paid immediately, even though it was their workers that didn't pick up the check we left under the mat for them. I do not recommend this contractor and will not be doing business with them in the future.
Edit: Owner was extremely rude to my wife and demanded full payment before the solar panels were reinstalled on our house

We built a new home at 7,300 ft in Indian Hills. The Capital team did a great job explaining our options, suggesting a system, installing it, & getting it all up and running. They did BOTH our thermal solar and in-floor hydronic / domestic hot water systems. Bruce has even given me some technical assistance on system settings and maintenance 2 years after the install. Highly recommend!

Laurent and his team installed a system on our home, for domestic hot water and heating, five years ago. It works great, and along with our solar PV systems we're nearly carbon free. I'd recommend Capitol Solar Energy to anyone. In fact I do already, to my own customers.

Capital Solar has worked on a number of jobs for me. The owner's are delighted with the quality of the product and I, as general contractor really appreciated their attention to detail and their working with me on the schedule. They arranged to have the home heated during construction which was a huge help to us. I recommend them highly!
