Compare Solar + Battery Options for My Home →When the grid goes down, standard grid-tied solar systems are required to shut off automatically. It's a safety regulation — your panels could feed electricity back into downed power lines and endanger utility workers. That means even if the sun is shining and your panels are on the roof, your house goes dark like everyone else's.
A battery backup system changes that. It stores the energy your panels produce during the day and powers your home independently when the grid fails. Lights, refrigerator, AC, Wi-Fi, medical equipment — whatever you need stays on.
Pricing varies significantly between installers and markets. These are typical ranges — your actual quote depends on your system size, location, and installer. That's exactly why comparing matters.

Pricing reflects typical installed costs in Nevada and Arizona markets as of 2026. Your quote may vary by installer, system configuration, and available incentives. Solar Resource USA compares quotes from multiple installers so you see the most competitive option.
Best for homeowners who want whole-home backup from a single unit with the highest power output. Built-in solar inverter simplifies installation. Premium pricing but fewest components to install and maintain.
Best for homeowners who want to start small and add capacity later. Each unit is 5 kWh, so you scale to exactly what you need. Ideal if you already have Enphase microinverters. Longest warranty at 15 years.
Best for value-conscious buyers who want solid capacity without premium pricing. 13.6 kWh matches the Powerwall. Scales up to 15 units for larger properties or full off-grid setups.
Battery pricing is not standardized. Two installers in the same city can quote the same Powerwall 3 with a $4,000+ price difference. The only way to know you're getting the best deal is to compare.
