SunPower is Helping Tri Cities, WA Go Solar
Tri‑Cities homeowners are increasingly exploring solar energy as electricity prices rise across Washington. With about 4.5–5.0 peak sun hours per day based on regional solar modeling, the Tri‑Cities region has some of the strongest solar potential in the state. Combined with Washington’s net‑metering policies and local clean‑energy initiatives, solar may be a smart long‑term option for residents of Kennewick, Pasco, and Richland.
Why Tri-Cities Is a Great Fit for Solar
The Tri‑Cities area is known for its dry climate, clear skies, and abundant sunshine — ideal conditions for solar energy production. Compared to western Washington, the region receives significantly more direct sunlight throughout the year.
Average peak sun hours (fixed tilt): ~4.5–5.0 per day
Typical system cost (5–6 kW): Varies by equipment, roof conditions, and installer
Estimated long‑term savings: Many homeowners may see bill reductions over time depending on system size, usage, and utility rates
System performance depends on several factors, including shading, weather, and system design.
Solar Incentives Available in Tri-Cities
Tri‑Cities homeowners may benefit from several state and utility programs that help reduce the upfront cost of going solar:
Net Metering: Washington utilities offer net‑metering programs that may provide bill credits for excess energy exported to the grid. Program terms vary by provider.
Sales Tax Exemption: Washington offers a sales tax exemption for qualifying residential solar systems, which may reduce upfront costs.
Local Clean‑Energy Initiatives: Kennewick, Pasco, and Richland support renewable energy adoption through sustainability programs and community partnerships.
Utility Rebates: Some utilities may offer additional incentives or pilot programs for solar or battery storage. Availability varies and may change.
Incentives and rebates vary by location and may change. SunPower does not provide tax, legal, or accounting advice. Customers should consult a qualified professional.
