This company lacks customer service. Called to inquire about a leak from PV panel they installed, no response.

I called yesterday and Poncho actually picked up. I explained what I've done to this point with no response and he said someone would call me tomorrow after their morning meeting to discuss. He gave me his cell # to text the information. I texted the info and he confirmed receipt. This is totally fine and acceptable. The next day, as promised, someone called and said they could fix the issue which was probably a bad inverter. The warranty would cover the parts but they'd charge me labor since I was not the original owner. My aunty was the original owner and I bought the house from

Great service from technician, Andre. He was very helpful in explaining options, and my questions. He was also very friendly, and extremely knowledgeable. He was very responsive to my inquires. If I could give him a grade, it would be an A+

I initially had my Solar Water Heater installed in 2008, and their system has worked well for the past 13 years except for some issues with the pump, which was easily taken care of by their staff.

So far so good. They have great customer service. They reply quickly and was able to come out to give me a quote and check my house within a couple of days. Cindy has been great to work with and the install has been going along smoothly.

Had my Solar Water Heating system serviced as per the 5 year standard. The service runs $325.00 for about 20 minutes of work and approximately $55.00 or less in parts. This to me being a contractor is somewhat high. Now that I know what to do I will service the unit myself in the future. However for those that do not feel comfortable servicing their own unit be prepared to pay a high price. The service includes flushing deposits out of the water storage tank, replacing the sacrificial anode that resides with in the tank itself and change the pressure relief valve located on the roof panel.
