Perfect Experience!

Amazing Company! Flawless installation, they started Tuesday and we got to go from SDG&E on Friday noon. That means less than 4 days! Most important: they LISTENED! Karin was very knowledgeable, honest and to the point at the initial interview. Fair pricing, knowledgeable staff, very reliable. Exceptional customer service. We’ve had our PV System now for about 1.5 years and no issues whatsoever. Would go with them again without a second thought! Highly recommend!

Flawless Solar Electric System Since December 2013

I use Clean Tech for both my Solar Electricity and Solar Pool Water Heating. In fact, I have enjoyed a Clean Tech Solar Pool System since ~2000. In 2013 Clean Tech reconfigured the Solar Pool System to accommodate our desire to install a Solar Electricity system. Clean Tech rose to the challenge when I asked for design aesthetics to preserve the 'original build' look of our home. Being very knowledgeable of building code requirements and skilled in solar system installations, our solar system installation pasted the building inspection on the first appointment. Bottom line is, we have not paid an electricity bill since going live. At this point, cost recovery of the solar electricity system is on schedule to finish in 7 years. A solar electricity system is well worth the money, and Clean Tech should be on your 'short list' of contractors to consider.
