Going solar in Tigard
A south-facing solar system in Tigard produces about 1,136 kWh per installed kW each year, according to NREL's PVWatts model. A home using about 11,000 kWh a year needs roughly 9.7 kW (23 panels) here, and a 7.5 kW system offsets about $1,704 of PGE energy charges in its first year.
Tigard homeowners offset some of Oregon's highest PGE rates with rooftop solar, backed by net metering and Energy Trust cash incentives.
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 10+ projects in Tigard, so our crews already know Washington County permitting and PGE interconnection here.
