7 Best Solar Battery Storage Systems

Best solar battery storage systems
Solar battery storage systems are ways to store energy for nighttime, cloudy days, or power outages. It is important to choose the best battery system for your home, and here are a few of our top picks.

First, Do You Need A Solar Battery Storage System?

If you have solar panels, solar battery systems are not necessary, but they can be beneficial depending on your circumstances.

  • If you experience prolonged or frequent power outages. Having a backup battery storage system is very beneficial in this scenario, especially if you have essential systems such as medical equipment. This will ensure that you have power, even when the electricity goes out.
  • If you live off-grid. If you live in a remote area or do not use the central utility grid, you will need a solar battery storage system if you want to use electricity at night or when there is no sun to generate power.
  • If your area has a Time of Use rate. In some places, the rate of electricity fluctuates depending on the time of day and the rate of demand. It can save you quite a bit of money on your electricity bill to use a home battery storage system if this is the case in your area.
  • If you want more sustainable energy. Rather than switching to the grid at certain times of the day, using sustainable energy through battery backup power gives you more sustainability and the use of renewable energy.
  • If your net metering policy is unfavorable. In many states, utility companies are working to remove or replace net metering. Having a backup battery bank may be the way to go if you are in one of those states and use solar energy.
  • If you want to be energy independent. Even if you live in a brand new HOA neighborhood, you don't have to pay a dime to your local utility company. With the right size solar energy system and battery storage, you can generate and store enough electricity to become totally energy independent.

How Much Do Solar Batteries Cost?

The average cost of solar batteries is between $8,500 and $10,000 not including installation. After installation costs are added, the cost of your battery backup system can be between $10,000 and $20,000.

Some factors that will affect the cost are battery chemistry (lithium-ion battery, lead-acid battery, etc), battery capacity, whether or not there is an inverter, battery size, and battery quality. The installation costs will also vary depending on local labor costs and the complexity of installation.
