Custom Solar stepped in…

“Custom Solar graciously stepped in to complete our solar system installation when our original contractor went out of business. We were pleased in every way by the professionalism of the staff especially in allaying our fears of losing more of our investment to another failed solar installation adventure. We’re also very pleased with the high quality of our SunPower panels & Enphase inverters, quality of installation, and the thorough follow through of Custom Solar’s staff to ensure we were completely satisfied with our new solar system.

We highly recommend that anyone who is interested in a solar system add Custom Solar to their short list of potential contractors.


“Wanted to pass along, that your crew that was out here is excellent. Hard workers, professional attitude, able to work with other subs, let alone work through some brutal weather… They were very safety conscious, and have professional attitudes and work ethics.”

Courteous and professional…

“Custom Solar recently completed the solar installation on our home. From start to finish, they were excellent to work with. They were courteous, professional and always available to answer questions. Our system has been up and running for two months and we are extremely happy with it. Not only are we saving money but we have lowered our carbon footprint.

Anyone wanting to go solar should consider Custom Solar.”


Friendly, professional, efficient…

“After months of research and talking with quite a few installers, we chose the proposal from Custom Solar. Their price was about the same, but what impressed us was the service we received. This includes not only responsiveness during the sales process, but the guys who came onsite to install were incredibly friendly, professional, efficient, and they really were on time each day.

They handled all the permitting and rebate process, and just did what they said and more. We are very impressed and recommending them to all of our friends, along with enjoying our new system. Pretty cool to watch our savings grow through their online application available 24/7. Go solar!”

“Just wanted to drop you a line to say thanks for the PV system. We’re psyched to have it running, powering the Leaf. Ben and the guys were awesome as well. Good team.”

Most competitive…

“We are quite pleased with the Custom Solar PV system installed on our home. The staff and crew were professional and efficient. They handled the building permits, inspections, dealing with Xcel and our lender, etc. When the system went operational, it delivered all the benefits of solar power especially saving on our utility bills with a small carbon footprint. We got several bids for our solar project.  Custom Solar’s bid was the most competitive.”


“Custom Solar’s full staff of engineers is adept at designing and understanding and integrating complex solar heating systems. They work hard, and truly care about the what they build, and the customers they interact with…. The understanding, enthusiasm, and expertise that Custom Solar brought to the project has been a pleasure. 

I highly recommend Custom Solar to anyone installing any type of solar system in Colorado. I’ve spoken to and worked with many different companies in the Boulder area, and Custom Solar is by far the best in customer service, and technical expertise.”

Friendly, knowledgeable, clear communication …

“Custom Solar installed our solar hot water system in Lafayette. They shepherded the rebate paperwork through the relevant state office, and even managed to get us an additional $1000 more than expected on the rebate. We needed service on the system a year or so after installation — they quickly identified the problem as being covered under warranty and got it fixed pronto. Definitely worth checking in with Custom Solar if you are looking into a system … and I’d guess their photovoltaic systems would be handled as professionally as our hot water system was.” – Eric T

“It would please us to know end to know that Eric received extra Kudos for all the wonderful service he has given to these very satisfied customers. – Candace and David

“Custom Solar installed a tankless water heater for our home. We’d asked a few different contractors for quotes and found that Custom Solar’s quote was competitive. The installer was professional, thorough, and organized. Custom Solar arrived on time to do the job, and the work was completed on the day they expected to finish. The work easily passed inspection and we’ve had many compliments on how nicely the water heater was installed from friends and neighbors.  I would definitely recommend this company to others.” – Michelle

“My husband and I have had the pleasure and fortune to have worked the last month or so with Eric  from your company. He has been so helpful in getting our long standing problems with our solar system sorted out, suggested a cost saving measure of putting an active summer loop on our system, and has been able to trouble shoot a problem we were having with the storage tank (that was built by another company.) In addition, he helped us track down a qualified boiler person who has been able to get our boiler problems fixed, after two years of inconsistent performance. Seems there was a recall that our other boiler person was unaware of, a simple fix but a frustrating two years. I had really considered getting rid of a 2 year old $10,000 boiler. Thanks to Eric’s help and willingness to find me a capable resource in Bernie’s, we now have a great working boiler that should last us for many years.” – Happy Customer

“Eric came out to our home today, due to my call saying the solar storage tank was not staying up to temp. He discovered a leaking coil inside the storage tank and a nail that had punctured the rubber liner, allowing water to leak from the tank. Both of these problems were caused by shoddy workmanship from the original company that we unfortunately had been involved with. Instead of simply doing the work and taking my money,( it would have been a VERY expensive fix), he suggested that the workmanship (the nail in the liner and the coils rubbing against each other causing a hole to be rubbed in the coil) may in fact be covered by warranty.

We will have the tank repaired and the coil problem resolved under warranty, but anything else will be done by Custom Solar. We have no desire to go back to the original company as we are so satisfied with Eric, his work ethic, knowledge base and integrity. He does put the customer first. Kudos to him.” – Happy Customer

“We wanted to write to you to tell you what an outstanding young man you have working for your company. We are very impressed as you can tell from our letter. Custom Solar has a long term client. We recommended your company just today to a friend who said he was having problems with his solar system. We will continue to recommend your company to anyone who needs great people to help with their systems.

In addition to Eric, we must also compliment Jaime and Travis who have both been very pleasant, and helpful in trouble shooting and scheduling Eric to come to our rescue as quickly as possible. You have a great team!” – Happy Customer
