About 5 years ago we installed solar on a Net Zero home in The Dalles, OR. Recently the homeowners were able to retire to Milton Freewater, OR. They wanted solar on their new home. The roof was not optimal but the incentives were excellent with Energy Trust of Oregon, Oregon Residential Energy Tax Credit and the Federal tax credit all in full swing. The main surprise for these homeowners is how much less this larger system cost them compared to the one they bought 5 years ago. “The price drop is astounding. I feel like I’m cheating!” The new system used 17 – SolarWorld 255 watt mono crystalline solar panels and Siemens micro inverters for a 4.3kW rated system.
