Phoenix has an extreme hot desert climate (Valley of the Sun) with summers regularly above 110°F (often 115-120°F peaks), mild winters, very low humidity, and exceptional sunshine (300+ sunny days/year). HVAC cooling capacity is the dominant residential system selection factor.

A 13.5 kWh battery provides 8-12 hours of essential-loads backup. Phoenix extreme summer heat (115-120°F peaks) drives HVAC sizing to handle 50+ degree differentials; tile and concrete roofing dominate (asphalt deteriorates rapidly under UV); shade structures and energy efficiency upgrades have the highest ROI; Arizona ROC license number must appear on all contracts
