What makes McAllen different
McAllen (population ~140,269) gets 5.13 peak sun hours per day — that's 3% 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.
