What are the top-selling solar batteries on the market

When solar battery prices start dropping at a rapid rate, that's good news. There are four leaders in the solar battery race, but the number is growing as rapidly as the industry.
•Tesla's Powerwall remains the best-known battery for residential systems, making the company a market leader. The Powerwall combines a 13.5 kWh battery with an inverter and control system.
•SunPower's residential and commercial businesses are geared toward high-end consumers. They produce more efficient solar panels than many competitors, but they plan to produce storage products.
•SolarEdge produces StorEdge, which will provide backup power. Plans are to produce a product containing an HD inverter combined with EV charging and energy storage could be operated via a smart home's energy hub.
•Sunrun is promoting its BrightBox energy storage unit and backup power provider in Arizona, New York, California, and Hawaii. The product will also cut peak energy rates when economical.


Unless you plan to go entirely off-grid, purchasing a solar battery will add some extra backup to your system.
