Contrary to what many people think, Washington state is not a perennial rainscape. In fact, More than half of the state is arid sagebrush steppe land, and even the emerald city of Seattle enjoys almost 70% as many sun-hours as L.A. annually. Summer days throughout the evergreen state are commonly clear, and last longer than anywhere else in the lower 48. Washington voters support sustainable energy policy, and legislation is a testament to that fact.
We’ve updated the Washington State Solar Incentives page today, check it out! For teasers though, look at the negative cost of a 5kW system:
Sample 5kW home solar electricity system cost — Seattle
- Cost before incentives: $35,000 (5,000Watts*$7/W)
- 30% Federal Tax Credit: Subtract $10,500
- Estimated annual production ±5,500kWh*: subtract between $825 and $2,970
- Avoided Energy Costs: subtract about $440 (cost of electricity increases 5.5%/yr)
- Years to payback: as fast as 7 years!
Estimated Net Cost: between $21,088 and $23,233
Estimated Net Cost in 2020:¡-$12,437!**
*in most of Washington, a 5kW pv system will produce much more than 5,500kWh of electricity a year. Ask your local installer for more details.
**that’s right. A negative cost. That is the same thing as a payment. In this scenario, the system has paid you to the tune of $12,437.00!!! A 35% ROI! We kid you not. Ask your local installer for a payback estimate!
