Due to the fact a recent customer decided to get a new roof before we install, and waiting on back-ordered parts, we are finally here on November 22nd for the panel installation. Ominous weather forecasts and Thanksgiving pushed us to work on the weekend and Monday to get off the roof part of the installation. As you can see the weather was perfect that day. Now, all thats left is the homerun wiring and disconnect that aren't so weather critical.
This is a grid tie net metering system with 24 modules rated at 220 watts for 5280 watts STC total. The inverters are Enphase D380's that connect to two modules each. This made wiring simple and less expensive than traditional systems. After inspection, our power company must follow through with their end of the deal. They have been rather slow about getting the new meters installed lately, and we hope sometime in December our customer will be enjoying the benefits of solar power. That will be the weakest solar month of the year for production but they can look forwards to really gaining output as the season progresses. This system should harvest 6 MWh/year given his exposure and some trees in the way in the morning and evenings. His SRECs should yield $1800 a year not including the "free" electricity.
Speaking of weather, I looked at our meter today and was surprised to see we had 460 KWh in credits. I can only attribute that the ongoing drought has produced more than usual sunny days and we have not used as much electricity. Next week is December and I suspect we will use those credits up if the cloudy days come. None the less, I am delighted we went this far without using net grid power.
