Having a solar panel system installed can be an environmentally and economically savvy move. In fact, the Solar Energy Industries Association reported that the market doubled in 2016 compared to the previous year. Solar power is not a fading trend – it is here to make the world a greener place. With the wave of solar power comes additional renewable energy options for homeowners, including options like solar batteries for storing solar power not used right away.
What Exactly Do Solar Batteries Do?
When a homeowner has a solar energy system installed, it includes solar panels, mounting equipment, a monitoring system, and an inverter to make the power from the sun usable electricity in a home. Most homes are tied to an electricity grid, which means any additional or unused power created by your panels will flow into the grid. In return, homeowners are able to draw excess power needed when their solar panels aren’t producing enough (such as at night). Typically, a credit will be given to homeowners for any extra electricity their solar panels produce and send to the grid. That means these credits will usually cover any excess electricity needed to be drawn back from the grid when the panels aren’t generating enough power– also referred to as net metering.
So what does this have to do with solar batteries? In theory, the batteries would take that excess solar power, convert it, and then store it for later use. The solar battery would then be the secondary power source your home draws from depending on how much power your solar panels produce.
Any excess electricity produced by panels once the battery is charged is then sent back to the grid. It essentially gives your home an extra storage of usable electricity. If your solar battery is depleted when your panels aren’t producing power, only then will your home draw from the grid. Additionally, solar batteries can act as a quick backup power supply in power outage situations.
Do I Need a Solar Battery for My Home?
Having a solar battery may seem like a natural step to take when you have a solar panel system up and running for your home, but it isn’t always necessary. In large part, whether or not a battery is practical depends on how your utility processes the power produced by your solar panels. If you get compensated through a credit for every kilowatt-hour of electricity produced (net metering), a battery may not make as much sense. If a battery is storing that power, you won’t get any extra savings on your electricity bill. On the other hand, if you are under time-of-use rates or demand charges, you may benefit greatly from having the flexibility of a solar battery to provide previously produced power during those times. Also, if you like the idea of being able to store additional solar power and reducing dependence on the local electricity grid, a solar battery can be a great option.
