Basics - Solar Water Heating
A properly sized solar domestic hot water heater in Oregon provides approximately 50 percent of a home’s water heating needs.
The solar water heating industry has matured a lot over the past 15 years. Systems today must be OG-300 certified to receive an Oregon tax credit. An OG-300 certified system meets performance, safety, design and maintenance standards established by the Solar Rating and Certification Corporation.
The chart below shows how much energy solar water heaters save throughout the United States. A solar water heater in Eastern Oregon can collect as much energy as one in Florida.
