Home Solar Production and Water Heating
Solar Now Oregon (solarnoworegon.org) hosts solar workshops and answers general questions. The site will connect you to other organizations including Energy Trust (energytrust.org/solar/residential), the Oregon Department of Energy, and the City of Portland Bureau of Planning and Sustainability.

Water heating and general use accounts for 1/4 of the average family bill, and systems are significantly cheaper to install than solar electric systems. The above resources will help you find rebates and incentives to cover as much as half your system cost. You could spend as little as $4,000 on a solar hot water system that alleviates 1/4 of your electricity bill, which pays off quickly.
