What role do batteries play in renewable energy systems?

Batteries play a crucial role in renewable energy systems primarily by storing energy for later use. This is especially important in systems that rely on intermittent energy sources like solar and wind power. These sources generate electricity when conditions are favorable (e.g., sunny or windy days) but cannot produce energy all the time. By storing the excess energy produced during these optimal conditions in batteries, renewable energy systems can ensure a reliable power supply even when generation is low or demand is high.

Storing energy allows users to tap into this power whenever needed, improving overall system reliability and efficiency. This capability supports grid stability and energy management, enabling a balanced supply despite the variable nature of renewable energy generation.
