The average cost to install solar on a home in Oregon is $4.16 per watt, with about 80 percent of systems installed for $3.15 per watt to $4.94 per watt. This is lower than the average solar cost in the Pacific Region of $4.79 per watt.
The average size of a solar system in Oregon is 5.3 kilowatts, which would cost around $22,000 without any federal, state, or local incentives.
1 kilowatt of solar PV in Oregon produces an average of 1,197 kilowatt-hours of electricity per year, so a 5.3 kilowatt solar system would generate 6,341 kilowatt-hours of electricity every year. An average household in Oregon uses 10,829 kilowatt-hours of electricity in a year.
With an average state electricity price of 11 cents per kilowatt-hour, this solar system could save a household in Oregon $692 each year. At this rate of annual savings, the system could pay for itself in about 32 years assuming no additional system expenses. This is longer than the expected 30-year lifespan of a typical solar panel.
