Adding a battery storage system to your solar panels can maximize the benefits of solar energy. Batteries allow you to store excess electricity generated during sunny hours for use later when the sun is not shining. This reduces your reliance on the grid and increases your self-sufficiency. While batteries do add to the initial cost, they provide long-term savings and peace of mind during power outages. In Ireland, where sunlight can be unpredictable, a battery storage system makes your renewable energy solution even more robust and cost-effective.
