A typical home solar system produces the most energy during midday when household consumption is often at its lowest. By storing this excess production, you can use your own solar-generated electricity during peak evening hours when energy costs are typically highest. This strategy, known as “self-consumption,” can significantly reduce your reliance on grid power and lower your monthly utility bills.
Modern battery systems are smart enough to automatically decide when to store power and when to use it. They can even learn your household’s energy patterns to optimize storage and usage. During power outages, these stored reserves become invaluable, providing continuous power to essential appliances and maintaining your home’s comfort and functionality.
For maximum efficiency, consider sizing your battery system based on your average daily energy consumption and typical solar production patterns.
