Solar Plus Storage, Investing in Solar Backup Batteries
How Solar Batteries WorkWhen you install a solar battery as part of your solar energy system, you can store excess solar electricity at your home instead of sending it back to the grid. If your solar panels are producing more electricity than you need, the excess energy charges the battery. Later, when your solar panels aren’t producing electricity, you can use the energy you stored earlier in your battery for night use. The system will only send electricity back to the grid when your battery is fully charged. And the system will only draw electricity from the grid when your battery is used up. Therefore, houses with solar-plus-storage can store excess solar power at their home for later use when the sun is not shining. And since solar batteries store energy at your home, they also offer short-term backup power in the event that there’s a power outage.
Why Install a Solar Battery versus a Backup GeneratorA solar battery provides peace of mind during a power outage. Specific rooms and appliances can be hooked up to this backup power source. And when the sun is back out, the solar panels will recharge the battery. This allows your backup power to continue. The energy generated by your solar panels can be stored in batteries for later use. In addition, the solar batteries:
- Smooth out solar panel fluctuations caused by changing weather and time of day.
- Reduce demand charges on your home’s electricity bills.
- Provide clean energy to the grid when it is more valuable.
- Make your home’s power supply more resilient.
