Matt Kennan
Homeowner, Austin, TX
Highest quality service, great on checking on products and any issues. Constantly check on my system originally my bill was $400 now my bill $60 great savings
Darin Harris
Homeowner, Austin, TX
CMS IS AWESOME!!! Very rarely do you come across a company that does exactly what they say they are going to do. Meaning CMS added the panels, took over the maintenance, and when I had an issue, a tech showed up the next day and I was producing again. Edgar and company are very knowledgeable and will go the extra mile to make sure the customer is first. My electric bills were normally $200 a month, but after CMS reconfigured my system, I am selling the extra energy back to my power company. WIN WIN….
Patrick Leberman
Homeowner, Austin, TX
Darren did an awesome job on the solar panels and bringing me up to par. Whereas I have no bill.
Jeff Hanna
Homeowner, Austin, TX
I highly recommend this solar company! From the initial contact to the installation, the entire process was seamless, professional, and incredibly efficient. The team was incredibly knowledgeable and answered all my questions thoroughly. They handled the installation flawlessly, and I’m already noticing a significant reduction in my electric bill
