The homeowner has electric heat so we made sure to focus on the monthly offset vs annual. The winter months throw off the annual usage but the goal is to get as close as we can to 100% offset while not over producing too much throughout the year. This will maximize ROI and limit any diminishing returns due to wholesale buy back rates on overproduction.
The graph below shows the monthly usage breakdown between utilities (in grey) and solar (in blue) over an entire year.
