How To Store Solar Energy
Solar panels only produce electricity when there is sufficient sunlight. Nights and cloudy days mean no electricity is flowing from the panels to your home. But if you have a way to store solar energy when it is generated, you can use that electricity at night or during inclement weather. And that is what batteries do best.
Deep Cycle Batteries
Deep cycle batteries, despite their name, wear out after many cycles of charging and discharging. They are the low end of your battery options and should be used only if you are on a very limited budget.
Industrial Strength Batteries
The downside of using flooded batteries is that they emit a chemical gas discharge when in use. This is a caustic and potentially explosive emission, so these batteries are not safe to use inside an enclosed area such as your home, attic or garage,
If installed in an outside shed or weather-enclosure, you need to also install vents so the gas can be dispersed outside the enclosure.
These are a much better option than flooded batteries, but there is still one that is much better.
Absorbed Glass Mat (AGM)
They are as safe as Gel batteries, but they hold their charge longer, discharge slower, and survive well over extended charging and discharging cycles.
If you can afford them, AGM batteries are the preferred way to go.
