The solar panels have dropped his electric bills to nearly nothing, and the rechargeable battery pack from Sunverge has kept the power on at his house during blackouts. It’s quiet and, so far, hassle-free, he said. The extra expense was worth the peace of mind.
“The lights don’t even blink,” Coleman said. “They stay on.”
Coleman is part of a small but growing group of homeowners coupling solar panels with rechargeable energy storage systems. These battery units provide power during emergencies and can potentially reduce power usage and bills.
But it’s also a new technology, which means it can be expensive and unreliable.
“At this stage of the game, energy storage isn’t quite for everyone,” said Cory Klausmann, vice president of sales at Simmitri. “There’s a select demographic that it works really well with.”
A typical home battery storage unit is a collection of rechargeable, lithium ion batteries, connected to power-generating solar systems.
