Do I need batteries for my solar system at home?

It depends on your energy needs and goals. A solar panel system without battery storage will generate electricity during the day, and any excess energy may be sent back to the grid. In the evening or when there is no sunlight, you will need to rely on grid electricity to power your home.

If you're interested in becoming more energy-independent and reducing your reliance on the grid, then adding battery storage to your solar panel system can be a good option. With battery storage, any excess energy generated during the day can be stored for use in the evening or when there is no sunlight, allowing you to use more of the electricity you generate and further reduce your dependence on the grid. Battery storage can also provide backup power during power outages and load-shedding.

However, it's important to note that adding battery storage to a solar panel system can increase the initial installation cost. The cost of batteries and their installation can be significant, and it's important to weigh the potential benefits against the added cost before making a decision. Additionally, not all solar panel systems are compatible with battery storage, so it's important to consult with a professional solar installer to determine if your system is suitable for battery storage.
