Solar systems generally cost $2.50 to $3.50 per watt. As an example, a 50,000-watt (50 kW) solar system would cost about $125,000 to $175,000.
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. Between 2010 and 2015, our medium and large business customers saw a compound annual growth rate of 1 percent. While that’s not an indication of future rates, it can help you assess 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.
If you choose the PGE Solar Payment Option instead, you may receive federal tax credits but you are not eligible for Oregon tax credits and Energy Trust incentives.
