In some cases, you can even sell the energy you’re storing back to the grid when the rates are higher and bank the profit. Battery storage lets you leverage low-cost energy that has already been generated and stored, ensuring your rates stay low and don’t affect your monthly budget. If your utility raises electricity rates, you can avoid that with a battery. This is also useful if you live in an area with frequent power outages. With battery storage, however, you can use electricity generated during the day later on, rather than relying on the utility for power. If you use the utility billing mechanism known as time-of-use, and don’t have a solar energy system, your electricity in the evening is likely more expensive because of the higher demand on the system. Here are the benefits of a solar-plus-storage system: But residential solar energy systems paired with battery storage-generally called solar-plus-storage systems-provide power regardless of the weather or the time of day without having to rely on backup power from the grid. You do need sunshine to generate electricity with solar, but what about the times when the sun isn’t shining? Most people rely on electricity from the power grid to supplement their solar-generated power.
When the power goes out in your neighborhood, you’d be blissfully unaware.Ī common myth about solar power is that you can count on it only when the sun is shining. Now imagine the same scenario, except you have a rooftop solar energy system with battery storage.
