Almost every solar system installed in California and Hawaii includes batteries. And for good reason. Daytime electric rates are low, evening rates are extremely high, blackouts are common, and utilities pay almost nothing for excess power you send back to the grid. But it’s not easy to design a battery system that takes into account homeowner power needs throughout the day, specific home wiring requirements, and building code restrictions on battery locations. Ironically, one of the biggest challenges is overcoming battery manufacturer hype that they can always back up your home for as long as you want during a blackout. My guest on this week’s Energy Show is Greg Smith, author of The Battery Powered Home. Because there is so much content to cover we’ve recorded two podcast segments with Greg. This first part focuses on battery system power and energy ratings — coupled with information about your home appliances — that will help homeowners make the right system design choices. Greg also delves into the three basic design approaches for a typical home battery system: arbitrage only, essential load backup, and whole home backup. So If you’re thinking about adding a battery to your rooftop solar system, or just getting a completely new combined solar and battery system, please tune into Part 1 of Tips for the Best Home Backup System with Greg Smith at www.energyshow.biz.
