Solar photovoltaic systems make up a small percentage of electricity generation in the state—less than 1 percent. But our output has grown exponentially, and solar is growing at a faster rate than any other energy resource in the country, as of November 2018. The solar resource availability east of the Cascades is typically 30-40 percent greater than the Willamette Valley or coast. However, solar energy technologies work throughout Oregon and generate electrical and thermal energy in all parts of the state.
When you install your solar system, 26% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is being phased out by 2022.
Most people are eligible to claim this credit (you must owe federal taxes to be eligible).
