Solar power in Portland, Oregon

PGE offer a rebate of $250 per kW up to $1,500 alongside other incentives. Oregon offers a state tax credit of $6,000 or 50% of the total cost. 30% of the remaining cost may be claimed as a deduction to federal taxes. The federal solar tax credit can be spread over several years and always covers 30% no matter the system size. Already a common 5kW system costing about $17,000 will only actually cost $6,650. Incentives like these are insane and make solar a simple choice in Portland.

PGE also offers net metering valuing every kWh exported to the grid at the value of another drawn from from the grid at a later time. When more energy is exported in a month than drawn from the home you will receive credit applicable to the next month. Net metering makes wiping out your electric bill easy. Incentives like these are some of if not the best incentives in the country and won't last forever!
