    It's also cool that you are getting upgrades for at no additional cost.

    Yes, I have everything to complete my system, including the M215's and the LG280 Panels, and the racking system. The original plan was to install the whole thing earlier this year. But it got hot and I had to stop. As it was, it took me a weeks, up at first light, and working until I was ready to drop each day. This way, I have a project for fall.

    How many panels are you getting? I know you told me before, that I have slept several times since then. It is great that you can get them all on south facing roof. That way you will get the most out of them.

      Do you have the M215s for the rest of your system yet? Or are you going to go for M250s?

      My contractor told me the LG 280 watt panels are no longer being sold. They are upgrading me to LG 285 watt panels and throwing in M250s, all at no extra charge. Seems reasonable.
      I'm wondering what price/system that you are getting. I have been recently quoted on a system with 22 x LG 285 pairing with M250s, but the price is crazy high.

        16 x LG 285s, with enphase M250 inverters. Not sure what else you want to know? Total before credits is about $24K, about $9K after credits.

          That is a great price. $5.25/watt before credits and $2/watt after. Good deal.

            Right, we hit a "sweet spot:" the NY agency that gives rebates to solar installers (NYSERDA) provides something like a little over $1 per watt installed, with a maximum of $5,000 - so our 4.5 kW system comes very close to maximizing that rebate. With a larger system size, the net cost per watt would by higher because of maxing out the rebate; with a smaller size, the rebate would be smaller while the dealer's fixed costs would prevent the gross price from being much lower (so again, the cost per watt would end up being higher).

            Interestingly, we didn't size the system based on that calculation. Instead, it was what would fit on the roof, plus the limit that NYSERDA has on system size - it can't be sized to produce more than 110% of previous year's electric usage; we are actually going to be very close to that in an average year. In all, it seems like this will work out very well - once it's finally installed!

              Thank you for the price update. It is great to have those incentives to offset the cost of system.

                Well, I paid $325 for the LG 280 watt panels, $125 for the M215 micros. Then there was the mounting system, trunk cables, wiring, disconnect, etc. My system cost me around $1.45 per watt. That is with me doing the install my self.

                  That does sound good. Keep us updated on your progress.

                          My system set a new daily high output today at 23.4 kWh's. My microinverters all pegged for about an hour. I was just barely able to see a flat top on my bell curves, but still nothing to be concerned about.

                          So maybe I will see some clipping this spring as has been suggested. But I can live with that as long as my system keeps setting new daily highs.

                            It only gets worse till the end of the year from now.

                              That was a result of one of the best days this year in TX. Low temps, crystal clear skies, and no humidity.

                                I am about to begin an installation and am considering a reconfiguration of my system depending on when the LA test lab approves the enphase m250 or aurora 0.3 micro. i talked to the building and safety folks today and they said both products are pending approval. if that happens, i'm swapping out 20 canadian solar 230s for lg280s or 285s (using enphase m250s), and installing 72-cell trina 295w modules paired with the power-1 micros. even off-grid systems (which mine is not) are subject to inspection, they said, which has me wondering if any diy-ers/installers have gone through the trouble to permitting/inspection for small off-grid systems (<5kW)..?
