How does a solar system work without battery storage?
Without battery storage, solar systems typically to use the utility grid as a battery. Solar energy is first used to directly power your home and the excess energy is pushed onto the local grid to power neighboring systems. When the solar system is underproducing, the home draws electricity from the local grid.
Do solar panels need battery storage?
Absolutely! In fact, most home solar systems are currently operating without battery storage. If you're fine with drawing from the grid and not particularly worried about power outages, you might not need a battery. However, there are benefits to having battery storage for your solar panels — and they are becoming increasingly common.
Should you use solar power without a battery?
However, your decision of going with or without a battery is based on the cost of a battery versus the benefits it provides to you. Even if you are using solar power without energy storage and just pulling from the grid, your carbon footprint will still significantly reduce.
