Washington Multi-Energy Solar Prices

While a 5 kW system will only cost you $12,901 in Washington, doubling the system size effectively doubles the price, so you'll pay about twice that for a 10 kW system. The higher the price tag, though, the more you'll get back as a credit towards your federal tax bill. Are solar panels worth it in Washington?
