Home batteries can make your solar roof a much better investment.
Home battery storage is moving from an exotic feature of the homes of the wealthy to a more mainstream option for any home with solar panels, incentivized by a new 30% federal tax credit. But If you think of batteries primarily as a backup technology, you’re missing the main way to justify their cost: saving money on energy every day.

The Generac system is modular, allowing the homeowner to add batteries in 3kWh increments up to 18kWh in a single battery cabinet housing. In this case, they chose three modules for a total of 12kWh of capacity, a number Heckedorn says is as close to an average as he sees and enough power to run three or four of the home’s dozen circuits for a few days.
