The Best Solar Batteries of 2026: Find Your
We rank the best solar batteries of 2026 and explore some things to consider when adding battery storage to a solar system.
By Sam Wigness | Dec 4, 2025 In the last year, nearly two-thirds of solar.com customers paired their solar panels with a home battery energy storage system (aka BESS). Why?
Because there's no perfect battery for every solution, here are the battery storage systems that solar.com Energy Advisors find work well with homeowners who invest in solar and battery. From a hardware and software perspective, the Tesla Powerwall 3 is an outstanding product.
Existing solar systems typically have solar inverters, which change the DC power produced by panels to AC power that can be consumed in your home or exported onto the grid. But if you want to store that AC power in a battery, it needs to be inverted again to DC power.
Solar battery cost in 2025 can range from $1,000 to $2,000 per kilowatt-hour (kWh) of storage capacity, before incentives are applied. So, for a 10 kWh battery (considered average size), prices can range from $10,000 to $20,000 fully installed. Battery storage pricing can vary quite a bit based on the brand, model, and its capabilities.
