The same home, every way to get backup power, all-in per month: electricity including delivery, plus the battery or generator, with purchases spread over 10 years.
The Tesla Powerwall lease is $122 a month in year one and rises 3% a year, so we show its average over a 12-year lease. Tesla also pays an $87 monthly grid credit while you stay on its Backup plan; it's left out because it isn't guaranteed. Sunrun's battery leases aren't priced publicly. Have a quote?

Try it with your billIt depends on how much backup you need and how much control you want. Base installs a 25 kWh battery (or two) for a low upfront fee, but you buy your electricity from Base, sign a multi-year contract, and Base decides when the battery charges and discharges. The reserve it keeps for you during an outage isn't disclosed. Run the comparison with your own usage to see the total cost against other options.
Divide the energy stored in the battery by what your home is using. Essentials like a fridge, lights, WiFi and fans use about 0.5 kW, so a full 13.5 kWh battery lasts roughly 27 hours. An average Texas home uses about 1.6 kW, so the same battery lasts about 8 hours. Running central air conditioning can cut that by more than half.
A standby generator runs as long as it has fuel, which suits long outages, but it costs around $13,000 installed, takes 10 to 15 seconds to start, needs yearly maintenance, and is loud. A battery switches over almost instantly, runs silently and needs no fuel, but only lasts as long as its stored energy.
No. The federal residential clean energy credit ended for systems installed after December 31, 2025. Be cautious of any quote that still counts it as a discount.
