i´m still happy with mine almost 9 years in. did have one panel broken in a hail storm and just got it replaced as part of the new roof.
what state are you in? i´m assuming you know the situation with net metering and whether/how much credit you get for what you put back on the grid? that´s the biggest factor IMO
I'm in MD, and this is what my local utility company's website has to say about net metering:
You are eligible to participate in net metering if you own or operate an eligible, private solar energy system less than or equal to 2,000kW (AC-rated) for your own use. To participate in net metering, your system should be sized to meet some or all your energy needs and cannot produce more than 110% of your most recent 12-months of energy usage. PSC rules state customers can generate up to 200% of baseline usage.
You can participate in net metering after receiving approval of your net metering application and a signed Certificate of Completion from BGE confirming your system has been installed.
Regarding credit for energy put back into the grid, they also say this:
BGE pays customer-generators at the Standard-Offer-of Service (SOS) rate. The dollar value of net excess generation shall be equal to the generation or commodity portion of the rate that the eligible customer-generator would have been charged by BGE averaged over the number of months the account was been net negative.
I'm not sure yet how that will translate to the reality of my situation, but I should get a better idea after this evening. I know our annual kw usage and was told that there would be no problem setting up a system on my roof that can cover that amount at a 'reasonable' cost (FWIW, my house is pretty small and the company I talked to estimated ~20 panels, so financing them over 20 years will hopefully hurt less than our current monthly utility bill).
We're still in a 'bottom line' mindset, in that the biggest question is how much, if any, our monthly utility bill goes down by switching, and what hidden costs there might be that would make solar a bad investment. From what little I've learned in the last few days, looking at it just from a budgetary perspective points to solar being a smart-ish move at worst and a long-term value at best, but until we get solid prices, I can't help but feel uneasy.
That said, this thread is reason #839483876598479 that the FFA is so great. So many topics have been covered here and recalled with a simple forum search.
