    Obvious an oily spill after drying after a few days
    Mark M.

    I purchased a 14 panel solar system from these people 8 yrs ago and was mislead from the start by being told I would have no bill other than a true up (average around $700 a yr so I guess they miscalculated how many I actually needed ) once a yr for using more electricity than my system produces...woops they forgot to mention the MID meter charge that went from $21 a month to $31...OK so I guess I was suppose already know that...I noticed a brown spot on one of my solar panels a few weeks ago so I called them for the first time since I purchased them...I was charged $250 to come out to look at it and also a $10 fee for using a debit card ...seems they try to gouge you every way the can think of... anyhow after a few days of waiting with no response I noticed that the brown spot was disappearing so I came to the conclusion it must be an oily spot from spilled jet fuel flying above no other explanation how it got there...so after looking at my inverter and noticed that the screen was not lit I thought that I could save the $260 if I could get someone to help me troubleshoot the problem at which time I was communicating with Greg the boss and explained the screen issue at which time Greg gave me the most vague instructions on how to turn the screen back on... he was saying that there is a blueish green button below the screen that needed to be pushed to activate the screen and at the position I was standing it was not visible to the eye so instead of further explaining that the button was hidden underneath a 2 inch gap between the screen and bottom part of the inverter (which would have made it too easy to find to the average person who has no knowledge about the inverter ) he had his guy come out at the last minute after he sensed that i was trying to troubleshoot the sceen light myself so the guy come to push the button himself so he could keep the $260 ... what honest customer service right ? So the guy walks through my gate and pushed the hidden button where it was located and looked at the brown spot and he came to the same conclusion as I did that it was so kind of oil spill... he left after 5 minutes and so later I emailed Greg to say that I could have pushed the button myself without his guy coming out to my house and would he consider waiving the $260 fee because of the fact he gave me the most vague directions on where to find the hidden screen display button...he responded with acknowledging yes I know the communication about finding the button was rather vague but he did come out at the last minute to the push the button for me and look at the oily spill spot from the ground level only to have the same guess as I did so he offered to send me back a check for $50... it just seems rather greedy to me to not refund at least half the money after spending 21k to have their company install my solar system so I just said send whatever you think is fair Greg at which point I have yet to receive any kind of refund after 2 wks ... is this the kind of scandalous company controlled staff you want to deal with ? I wish I wouldn't have gave them the business... Even after suggesting to pay off the system last year I found out that you do not get out of paying the interest rate weather you pay in full or make monthly payments for the next 20 yrs they WANT YOUR MONEY !! So it's a costly investment with poor customer service ... I hope this might help someone else avoid choosing to make the same mistake as I did... check out other solar businesses with more honest helpful customer service.

    Emails from Gus in September and now it's November with no call back from anyone. I also copied the Service Dept.

    My wife and I purchased a new 19 panel solar system and Tesla Powerwall in mid 2025. The install…read morewas completed in October 2025. The crew and all of the people at United solar Electric were very responsive and professional. I would, and will do business with them again, (adding an additional battery). PG&E was a problem. PG&E was very slow with providing PTO (permission To Operate). We did not receive PTO until end of May 2026, over 6 months from the date when system was operational. PG&E will need to upgrade transformer (December ???) before we can send greater that 2000 watts back to the system. Right now, we have conditional permission to operate, limiting output to PG&E to 2.2 KW. To United Solar Electric's credit, they were with us the entire time dealing with PG&E and were just as irate with PG&E as we were. Thank you, United Solar Electric!

    I highly recommend United Solar and especially Ben Vanni. I first worked with Ben about six years…read moreago when we installed our original 14 solar panels. We had such a positive experience that when we decided to expand our system, I reached out to Ben and United Solar again. This time, we added another 16 solar panels along with two Tesla Powerwalls. Once again, Ben and the entire United Solar team did a great job. The installation and inspection teams were professional and efficient, and the whole process went very smoothly. Ben kept me updated throughout the project, communicated clearly, and was always willing to answer my questions. I also appreciated that they kept their pricing competitive while still providing excellent service. After working with Ben and United Solar twice over the past six years, I can confidently recommend them. Great service, smooth installation, good communication, and a team you can trust. Thank you, Ben and the United Solar team!
