Solar Energy FAQs for El Paso, TX

How many solar panels do I need in El Paso?

For a typical 1,800 sq ft home in El Paso with an electric bill around $180/mo, a system between 6.5 kW and 8.5 kW (approx 17 to 22 400-Watt panels) is required to offset 85% of annual consumption, accounting for El Paso's 6.1 daily peak sun hours.

Do I need home battery backup storage (like Tesla Powerwall)?
