What Is Solar Battery Energy Storage?
Home energy storage devices store electricity locally, for later consumption. At their heart are batteries, typically lithium-ion or lead-acid, and intelligent software. An energy storage technology, they are downstream relatives of battery-based grid energy storage and support the concept of distributed generation. When paired with on-site generation, they can virtually eliminate blackouts in an off-the-grid lifestyle.
The stored energy commonly originates from on-site solar photovoltaic panels, generated during daylight hours, and the stored electricity consumed after sundown, when domestic energy demand peaks in homes unoccupied during the day.
Batteries paired with your solar system are essential for energy independence. Use it as a battery back-up for your solar panels for when your electricity goes out—like a 'solar generator' of sorts — or go completely off-grid. You can also have your solar system run off the battery at night, when there is no sun available to produce power and you're relying on net metering to cover your energy consumption. Either way, you can rest assured that even when your neighbors lose power, your home will still be humming!
