50% less electric usage, in most expensive state in the US ME

We bought the Delta Ultra Pro, two batteries, inverter and smart home panel.

The install was completed end of August and we have saved more than 50% on electric since install! With unpredictable weather it has been awesome hands off system running battery most of the tome and switching to grid when we have several days of clouds! We installed the solar panels on the walls of the house se we literally never worry about snow or cleaning panels! At this rate ROI will be in two years! The inside pics were during SHP2 install. All walls are covered now!
