Solar in Kirkland: What Homeowners Should Know
Kirkland sees an average of 3.7 peak sun hours per day, which is what ultimately determines how much electricity a rooftop system produces here. A standard 8 kW system (about 20 panels) generates roughly 8,643 kWh each year in Kirkland — and paired with Washington's local electricity rate of $0.093/kWh, that's where the savings come from.
At those numbers, a Kirkland homeowner saves about $67/month ($804/year). Against a $24,800 system cost (about $23,800 after Washington state incentives), that works out to a payback of about 29.6 years, after which the system produces essentially free power for two decades — an estimated $3,657 in lifetime savings. Note: the 30% federal tax credit expired at the end of 2025 for purchased systems, though a solar lease or PPA can still pass it through. The local grid is served by Puget Sound Energy, whose net metering policy directly affects how much credit you earn for surplus power.
