A common concern many customers have is what happens to their solar panels during a power outage. It’s a natural question, especially when relying on solar energy for your home’s electricity needs. Let’s clear up some misconceptions and explain how solar systems work during grid outages.

1. Solar Panels and the Grid

Most solar energy systems are connected to the local electricity grid through a process called “grid-tied.” This allows homeowners to send excess energy back to the grid and draw from it when needed. However, during a power outage, grid-tied solar systems automatically shut down for safety reasons. This prevents electricity from flowing back into the grid and endangering utility workers who may be fixing the lines.

2. Can Solar Panels Provide Power During an Outage?

Unfortunately, without additional components, grid-tied solar panels cannot provide electricity during an outage. This can be surprising to some homeowners, as they assume solar panels would continue to work independently. However, without the grid’s backup, the system halts its production.

3. Adding Battery Storage for Backup Power

The solution to this concern is to pair your solar system with a battery storage unit. A solar battery, like Tesla Powerwall or LG Chem, stores excess energy generated by your solar panels for use later. During a power outage, the battery kicks in and provides electricity to your home. This way, you can continue to power essential appliances and devices even when the grid is down.

4. Hybrid Systems: The Best of Both Worlds

For homeowners who want peace of mind during power outages, a hybrid system that combines solar panels with battery storage offers the best of both worlds. You can enjoy the financial benefits of a grid-tied system and the reliability of backup power when you need it most.

Conclusion

While grid-tied solar panels won’t function during an outage on their own, adding a battery storage system ensures that you’re not left in the dark when the power goes out. With the right setup, solar can provide you with energy independence and peace of mind in any situation.
