Started off with them offering $500 bucks for a good review... After we signed and agreed to the install design they wouldn't answer my calls. When they finally did the original sales man joe cant help anymore so he passes you onto sue. She was off island and didn't have much information so she had to get back to me. Finally she said October 8-9 the system would be installed and good to go. 2 months of a wait time, but it was to be expected for Hawaii shipping and what not. October 10 and the guys left after the third day of the install, we burned leave by the way to sit at home while they were on our property. But no one was there to help us flip the switch and turn it on, or anything cool like that, and I couldn't find where they put our battery's? So I called sue the next day, no one answered. I kept calling and eventually someone answered and said the batteries weren't here. Scott told us that it was because of the new trump import thing and now our batteries were in California.... no one told us that we were missing half the system before we wasted leave to have them install part of our stuff??? So he says the batteries will be here in mid November. I wait. No calls. I call him late into November... still nothing on where my batteries are. Enerbank has now notified us that we have allowed mercury solar to drag their feet for so long that our second portion of the loan was about to expire (side not, in big bold text it says "do not sign the second portion until after the job has been completed to your expectations". To mercury solar it meant nothing, and they tried multiple times to pressure us into signing the final portion of the loan and pay them the full balance. At which point I am sure they would become even harder to get ahold of. We did as everyone who dares to use this company should do, and told them "no way, finish my install then you will get paid". December came and went with no update, nothing. So I called and Scott decided he would do a visit to our house. At that point he realizes that he doesn't want to spend the time or money digging a line into our detached garage for the batteries (that we have waited so long for) to be installed as we agreed to in our contract. At this point he offered us 2 battery's that hold less storage slightly, but is more expensive equipment (still less then the labor and parts would have cost them to install our batteries in the garage as we had originally agreed to, but they look alright and we just want this install over with at this point, so price is irrelevant with how much of my time they have wasted and the cost they would have incurred either way installing our system as designed originally). In the end we agreed because he "had the butteries on hand and could install right away to finish our system". He left and boom no call. Nothing again. Mercury solar contacted enerbank to push our expectation date on the loan out to Jan 10, 2020. Guess when they decided to schedule installing the batteries that they "have on hand"? January 8-9 2020. Really dude. So we say sure, what's another month, but we demand they pay up for what the system was quoted to produce to offset our electric bill AND OUR SOLAR LOAN PAYMENT that we have been paying since October! Wtf dude, so they agree to pay us back for part of the extra payments that we have been required to make because of their slow speed install. Which is fine. Jan 8-9 passes and whoops, system doesn't work, half of our panels/power optimizers have decided to poop the bed. The loan expires on the 10th and mercury solar again starts pressuring us to just sign the documents. "I know it doesn't really work but just go ahead and sign the second payment". Still had yet to pay us for the months of non-production. We tell them no payment until the system is working and we get our payment for the 4 months they are behind schedule. They provide us a check, come back on the 10th and got our equipment replaced. But it was still under producing. the 15th it was fixed so they demanded payment, got mad when it wasn't submitted same day.. they left my yard a mess, wires, big chunks of metal, they damaged my siding. Obviously a very self centered company. I plan to expand the system to produce more power within the next year and will not be even considering using mercury solar again. Go with any other company. There are a lot of better bigger companies on island that are dependable and stick to the established time line. Use someone else. Their ratings are inflated, they don't deserve 2 stars. If you want quality look elsewhere..... it's to late for me but you have been warned! read more
