How much can solar save on a Midstate bill in Sunriver?

At Midstate's average energy charge of about 10.86¢ per kWh, a 7.5 kW system offsets about $1,190 of energy charges in its first year. This estimate assumes no rate increases, so real savings are usually higher.

What solar incentives are available in Sunriver?

Midstate is outside the Energy Trust of Oregon service area, so its incentives don't apply here. Sunriver homeowners still get Oregon's property-tax exemption, the Oregon Solar + Storage Rebate when funds are open, and Midstate's own net metering or interconnection program. The 30% federal homeowner credit ended for systems installed after 2025.

Going solar in Sunriver

A south-facing solar system in Sunriver produces about 1,461 kWh per installed kW each year, according to NREL's PVWatts model. A home using about 11,000 kWh a year needs roughly 7.5 kW (18 panels) here, and a 7.5 kW system offsets about $1,190 of Midstate energy charges in its first year.

Sunriver's second homes and full-time residences both benefit from solar plus battery backup. With Midstate Electric service and strong sun, storage is especially popular for winter outage protection.

High-desert sun and cold, clear winters are close to ideal for solar: panels run more efficiently in cold air, and snow slides off tilted modules within a day or two of a storm. Racking and attachments are specified for local snow loads.

Midstate Electric Cooperative serves La Pine, Sunriver, Chemult and the rural south Deschutes and north Klamath county area, where long winter outages make battery backup popular.

National Solar has completed 2 projects in Sunriver, so our crews already know Deschutes County permitting and Midstate interconnection here.
