According to the Solar Energy Industries Association, solar’s long-term success “depends on the cost-effective integration of energy storage”. Already, excess solar power is often wasted, and California is only a third of the way to its 100% clean energy target. Achievement of this bold goal will require energy storage at scale to harness solar power after sunset. Meanwhile, California will have 5 million electric vehicles on its roads by 2030. Recycling their batteries is expensive, but reuse is economical; over 75% of an EV battery’s original capacity typically remains at the end of its useful life in a vehicle. RePurpose Energy tests, reassembles, and redeploys used electric vehicle batteries to provide commercial solar developers with energy storage solutions at half the cost of new battery alternatives, so they can offer more electricity bill savings, and California can accomplish its clean energy goals.
