How do I choose the best solar installer in Washington?▼

How much does solar cost in Washington?▼

What solar incentives are available in Washington?▼
All Washington homeowners can claim the 30% federal solar Investment Tax Credit (ITC). Solar equipment is exempt from sales tax.
How long does solar installation take in Washington?▼
The physical installation typically takes 1-3 days. However, the full process from contract signing to system activation usually takes 4-12 weeks, with most of that time spent on permitting and utility approval. Timelines vary by installer and local jurisdiction in Washington.
Should I get a solar lease or buy in Washington?▼
Buying (with cash or a solar loan) typically provides the best long-term value since you own the system and receive all incentives. However, leases and PPAs require no upfront cost and still save on electricity. In Washington, with a 12-year average payback period, buying usually makes financial sense if you can afford the upfront investment.
