The state of solar power in Portland, OR

Portland, OR, currently ranks in 20th place when it comes to total solar installations in the U.S., according to the Shining Cities 2019 report. The per capita ranking is a bit lower, with Portland claiming a solid 24th.

Very few would associate Portland with sunshine - and they aren't wrong - the area is certainly better known for its abundance of rain. Still, a combination of favorable local legislation and strong incentives make Portland a viable location for solar power.


How much solar power does Portland, OR produce?

Portland currently has 31.2 MW of total solar installation capacity. The per capita numbers sit at 48 watts per person. Yet, Portland has a lot to be proud of. It manages to stay in the top quarter of states in the U.S. for solar, even surpassing some states in solar hot zones.

The situation in the state of Oregon is similar. Oregon is in 20th place in the U.S., with 613.57 MW of solar installations. In the next five years, Oregon is expected to add an additional 972 MW of solar installations, which would more than double the total solar capacity of the state. It is important to keep in mind that this still ranks Oregon in the 25th place in terms of solar growth in the next five years.

Is solar power generation feasible in Portland, OR?

In terms of location, Portland, and Oregon in general, have very little working for them. Located in the rainy Pacific Northwest, Portland is known for its gloomy weather and sporadic sunshine. The amount of solar radiation leaves a lot to be desired, as well.

Portland receives around 3.5 hours per square meter per day of solar power, depending on the index used. These figures are nowhere near what sunny states like California and Arizona receive on average.

However, the city is very progressive when it comes to solar legislation and incentives. Solar growth favorably correlates with the number of subsidies, rebates, and local incentives offered for going solar, as well as the overall awareness of the issues such as climate change and environmentally-friendly power generation.

How can I start using solar in Portland, OR?

Very few think of sunny skies when thinking of Portland, but the local legislation and incentives make a compelling case for going solar.
