So, I have reached paralysis by analysis, I could use some advice pro's cons etc. My house faces directly south, two story no shade. We have 1 for 1 Net metering for 12 months then resets. 25.00 A month connection fee and a max system of 10.KWdc I have received numerous bids and options from my research to be reputable solar installers in my area.
Main questions. Depending on panel wattage I will need between 27 and 31 panels to get to 10KW, I have bids for LG and Rec panels. The bids range from 28K for REC N series to 32K for LG 350N1's or REC Alphas I had it specd with iq7+ (possibly future proofing if that 10KW ever changes) The biggest difference between the panels is the REC N series has 25 Years 86% guarantee and the others are 90-92%
So, does spending the extra 3-4k on better panels now gain me anything? My initial thought was Yes, I could get to 10KW with 3 or 4 less panels, but with panel efficiency's getting better every few years. I figured at current rates I could just replace a few panels with higher efficient panels to make up the losses of degrading panels. Am I missing something in my logic? Thanks for the help.
