Total 28.94kWDC PV Capacity

Ground mount installed 2017, roof mount 2019. System paid off Oct 2023. The utility pays me!

We bank approximately 5MWh each summer, and draw on it in winter via 1:1 net metering in Maryland.

Additional efficiencies include HP water heater, inverter mini-split, dual-stage central HVAC, and blown insulation.

We use 25MWh annually, which is a ton. But #datahoarding storage drives burn watts!!
