Going solar in Gresham
A south-facing solar system in Gresham produces about 1,114 kWh per installed kW each year, according to NREL's PVWatts model. A home using about 11,000 kWh a year needs roughly 9.9 kW (24 panels) here, and a 7.5 kW system offsets about $1,671 of PGE energy charges in its first year.
Gresham homeowners protect against rising PGE rates with solar plus optional storage.
Portland's reputation for rain hides how productive its summers are. Most of the year's solar output comes from May through September, and net metering banks that surplus for winter bills.
PGE serves the Portland metro, much of the north Willamette Valley and Salem. Its optional Time of Day plan prices on-peak power (5 to 9 p.m.) highest, which is where battery storage earns its keep.
National Solar has completed 4 projects in Gresham, so our crews already know Multnomah County permitting and PGE interconnection here.
