Is solar worth it in Oregon in 2026?
With an average electricity rate of 12.6¢ per kWh and 4.5 peak sun hours per day, Oregon homeowners are in a good position to benefit from solar panels. A typical 8kW system will produce around 10,512 kWh per year — enough to offset a significant portion of a typical Oregon home's electricity usage.
At current electricity rates, that production saves approximately $1,324 per year. Over 25 years — the standard panel warranty period — the projected net profit after recouping the system cost is around $16,300.

What affects solar savings in Oregon?
Every homeowner's solar savings are different. In Oregon, the key variables are:
- Electricity rate (12.6¢/kWh): Oregon's electricity rate is near the national average. Combined with sun hours and system size, this gives a typical homeowner a solid case for solar investment.
- Peak sun hours (4.5 hrs/day): Oregon's sun hours are below the national average. This is offset by choosing an appropriately-sized system and optimising roof orientation. South-facing roofs at 20–30° pitch perform best.
- System size (8kW typical): The right size depends on your electricity bill. A $150/month bill typically requires a 6–8kW system to offset 80–100%. Use our System Size Calculator to find your exact target.
- Roof type and orientation: South-facing roofs at 30° pitch are ideal. West-facing roofs produce 15–20% less but may generate more electricity during peak-price afternoon hours, improving time-of-use savings.
