OPS were extremely professional, very responsive, and always answered my questions to satisfaction. Got me on the schedule sooner than expected. Brought masks for virus safety and wore them during conversations. Finished the job quickly and without issue. Very friendly.
They described themselves as pretty minimalist. Meaning essentially they don't partner with financing companies. They did give me contact info for a couple banks but I dealt with the loan paperwork on my own. The upside of this is you save a ton of money. I looked at several solar companies and OPS was by far the cheapest for the hardware you get. Save yourself unnecessary costs and get good hardware anyway from a very good team with OPS. Their workmanship is guaranteed basically for the life of the panels- I hope I don't have to put that to the test but so far so good. They also dealt with all permitting and whatever else needed to go through DP&L for net metering so I didn't have to think about those details.
It also hailed a bit, to my terror, like a week after installation. But they appear undamaged and unfazed.
OPS also offered to install a squirrel guard to prevent critters from messing with the electronics under the panels. When I suggested I'd prefer to save money, they sent me the site to order the guard myself directly and even gave advice on how to install it myself. So I'm very happy they were more concerned with my satisfaction than trying to pressure me into spending more on them.
My panels are producing great, even more than expected on cloudy days. I'm looking forward to my next DP&L bill!
I will definitely go straight back to them whenever I build up the savings to get storage or do other energy improvements. Highly recommended.
