What makes Kent different
Kent (population ~126,952) gets 3.51 peak sun hours per day — that's 8% less sunny than the Washington average of 3.8. Slightly less local sunlight means panels produce a touch less than the state average, so sizing and orientation matter. Electricity rates, net metering, and incentives are set at the Washington level: residents pay about 11.1¢/kWh, and full net metering + sales tax exemption.
