Sun Solar (Formerly Missouri Sun Solar)

Leaking roof

My system was installed in 2013, my ceiling is ruined. The "front desk" lady is nice, but I haven't had any other responses. I first contacted them 3 weeks ago. I just want my panels moved to a ground install.

Poor customer service

Really sad customer service. Sun Solar replaced my original inverter back in 2021 since my initial installer had gone out of business. They had me sign an administrative transfer of rights to monitor my system and had a tech come out and do the work. He was great, and no issues, until that inverter quit working in less than two years. This was a warranty claim, and instead of taking care of it, they told me I wasn't a customer and they're not taking on any new customers. So you have administrative rights to monitor my system and I've paid you $380 in labor to fix my system in the past, (after being quoted $280), but I'm not your customer? What a bunch of bs that is. Why monitor a system you have no intention of helping fix if there's an issue? I asked them to send me a form to revoke those monitoring rights. Find another company that will stand behind their work. Instead of scheduling a tech for half a day they left me stranded with no working inverter and no company to fix it. I'll be leaving this review every place I can find to leave it. Hopefully it keeps others from contacting this company.

Poor service, incomplete installation

Had a Generac pwrcell system installed with battery's March of 2022. Everything was fine until September when we had a power outage and the main inverter failed. Took over a month to get someone out to look at it and longer to get it fixed. I asked for the pv map and they installed 6 strings on 2 inverters for a total of 10.8kw. Completely unnecessary considering that each inverter can handle 15kw of pv power. This is where the incomplete installation comes in. Only 5 strings were ever working at any one point. When they removed the Snaprs they connected to a different pv optimizer and it finally showed up on the Dashboard view but the other one that was previously connected shows that it's deactivated. Their technician seems to be hung up on my utility voltage being 252v saying it's too high. However, I have one inverter that has never failed plus the installation manual says the inverters can go up to 260v. They clearly don't know the product they were selling and then never finished installation or did any timely repairs. I just made my 1st payment on this system and it's only worked properly for 6 months. If I could go back I'd avoid this company.
