Going off the grid with solar batteries

Newer, more efficient solar panels and inverters have been in the news recently, but advancements in solar technology aren’t limited to standard equipment. Energy storage is also moving closer to mass-market adoption, and more installers are offering solar batteries and solar panel battery banks (a.k.a. solar-plus-storage) as an option for homeowners. Solar-plus-storage systems include a battery that captures and stores the excess solar energy generated by the PV system, opening up the possibility of going “off the grid” – a tempting proposition for homeowners who want to sever their connection with utility companies by using renewable energy.

Since solar battery technology is relatively new to the solar market, there isn’t significant solar storage capacity deployed in the U.S. That won’t be the case for long though: between utility and residential installations, solar battery deployment is expected to increase twelve times over in 2015. As solar batteries become cheaper and more accessible for homeowners, more people are wondering, “Can I use solar batteries to go off the grid with my solar panel system?”
