A new report from GTM Research — U.S. Residential Solar Economic Outlook: Grid Parity, Rate Design and Net Metering Risk — sheds light on the growing residential solar market in the US.
According to the report, 20 US states are currently at grid parity, while 42 states are expected to hit the same threshold by 2020 under normal conditions.
Residential PV hits grid parity when the established cost of solar energy dips below the gross electricity bill savings in the first year of a PV system’s operation.
