Solar battery backup systems are more like insurance policies than investments. While it’s easy to calculate return on investment for solar, it’s not that simple for a solar battery backup system. Your peace of mind, however, is invaluable.
Solar doesn’t work when the grid goes down. You need a battery backup system installed, but a good battery system can be expensive. A battery powers your home during outages and protects against rate hikes. The return on investment, however, is hard to calculate.
Peak Shaving and Backup Power are the biggest benefits of battery systems.
Peak shaving is managing your energy usage to avoid pulling power from the grid during on-peak hours. To avoid high energy charges, you use the power stored in your battery or sell your power back during those peak rates.
Battery software lets you manage when and how you use power. You control your energy usage significantly more than with solar alone. While this has financial value, it’s not easy to determine your break-even point; it’s more about maximizing and insuring your solar return on investment.
Which Solar Battery Is The Best?
The Tesla Powerwall 2 is the best battery on the market today, but many others are available. The Tesla Powerwall 2 is exclusively available through authorized dealers, while the LG Chem is available through most installers.
Eguana, Enphase, and Panasonic are becoming popular options. Adding a second battery to your energy storage system drops the price per unit because the cost to set up the electrical is only paid once. The second battery gives you a longer amount of charging time, not more load power.
There are some rebates available; check with your contractor as they change frequently for solar battery backup systems.
Solar power is a reliable source of energy when there’s no electricity. You can protect your family with a solar powered flashlight in your emergency supply kit. And protect your home by choosing the best solar company to do your solar and backup battery installation.
