Here Comes the Sun!

A short blog update to provide you the latest data from my solar PV system. I have the data below for the first 2 weeks of May added to my monthly kWhr of generated power generation.

I've mentioned in earlier posts that we need to generate approximately 375 kWhr per month to have the system pay for itself. As we've seen, December and January can be poor due to clouds and snow shading the panels. But March, April, and the first half of May have been good and more than cover the low generation from Dec-Feb. We are quite pleased that we are approaching 10,000 kWhr - likely by mid-June.
