Power Stac vanadium redox flow battery hopes to take advantage of California solar mandate

Date: Aug 15, 2018

Renewable Energy and Power (REAP) announced expanding marketing activity for the company’s Power Stac vanadiumredox flow battery (VRFB) power storage system.

California has mandated that, as of 2020, all new houses and multi-family residences of three stories or fewer, along with all major renovations, must be built with solar panels. With other states to follow, the demand for power storage for solar generation is certain to grow.

The ability of vanadium redox flow batteries to fully cycle and stay at 0% state of charge makes them ideal for solar storage applications where the battery must start each day empty and fill up depending upon the load and weather.

Power Stac can last for 10,000 cycles with no significant degradation, equivalent to 25 years of storage, matching the life of solar panels and wind turbines.
