Understanding Solar + Storage
Why get a battery?
Solar panels alone won't keep your lights on during an outage. Here's how batteries complete your energy system.
Solar panels shut off during outages
Most people don't realize that standard solar panel systems are designed to automatically shut down when the grid goes out. This is a safety requirement to protect utility workers. Without a battery, your solar panels become useless exactly when you need them most—during a power outage.
Your solar investment is only working at 50% of its potential without storage.
