What makes Richardson different
Richardson (population ~110,815) gets 4.78 peak sun hours per day — that's 10% less sunny than the Texas average of 5.3. 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 Texas level: residents pay about 14.6¢/kWh, and no state mandate; utility solar buyback plans + local rebates.
