Lighthouse solar struggled working with Enphase and Sharp and replaced one solar panel, two Enphase inverters and moved two panels. This did not fix the problem or even relocate it, nonetheless they remained convinced that the problem with the system was a faulty solar panel or panels. However, the more they struggled to solve the problem, the more it seemed to expand. The problems with my solar system that seemed to get worse with each repair they tried to make, the franchisee of Lighthouse Solar that I worked with went out of business or moved on. During the months while I was attempting to have my solar system serviced a second panel then a third panel failed. By December of last year a forth panel or inverter appeared to fail and I was down to 28 panels reporting..
The solar photovoltaic system consists only of panels, inverters and wiring- to me it was becoming increasingly clear that the problem was not originating in the panels or the inverters. There had been difficulty with the original installation- it had failed the electrical inspection three times before finally passing. Now it was clear to me how critical good electrical design and installation are to a solar system. I was fortunate that when Lighthouse Solar exited the business he arranged with ProspectSolar to install a second solar panel that he believed would fix my ever growing problems (at that time my Enphase system only had 29 inverters reporting). When the field Superintendent for ProspectSolar came out, he pointed out all the visible problems with the wiring that he observed and took several pictures so that I could see the problems, too.

And so between snow storms and frigid weather Jose and the crew rewired the system using rain tight fittings (see photosabove), replaced conduit with prefabricated fittings and proper grounding. When he was done and the system turned back on I had only 28 panels reporting. It would take until spring for Jose to get back here with 4 new Enphase inverters. After installing those I had 24 panels reporting-he had replaced the wrong inverters. During the rewiring the physical location of the reporting inverters had changed and no longer matched the map provided by Enphase. So once more Jose was on the roof replacing inverters using a hand mirror to read the serial numbers to make sure he had the right ones this time. After two days of that I once more had 28 panels reporting and producing power. Today, Enphase updated the system and added the new inverters. Jose called and I refreshed the system and had all 32 solar panels producing and reporting. Just in time for a sunny spring. It appears that just as Jose promised that the system is repaired.
