Solar systems generally cost $3.50 to $4.50 per watt. Home solar system sizes vary, but most are 3,000 to 7,000 watts (3 to 7 kW). As an example, a 3,000-watt (3 kW) solar system would cost about $10,500 to $13,500.
Use the Energy Trust of Oregon solar cost calculator to see how installing a solar system might impact your budget.
Be sure any estimate you get is based on a realistic projection of your current and future electricity prices. On average, PGE residential prices saw a net increase of 2.5 percent per year from 2010 to 2015. While that’s not an indication of future rates, it can help you asses the projections on which your bids are based.
Incentives and tax credits
Cut your net cost for solar by thousands with Energy Trust incentives and state and federal tax credits.
Energy Trust incentives require installation by approved contractors, and other requirements for credits and incentives may apply. Ask your contractor for details.
If you participate in the PGE Net Metering program, you are still eligible for tax credits and Energy Trust cash incentives.
