Stored Energy Smackdown: Solar Generator vs Battery Bank, Which Will Win?

Solar generator and battery bank are two terms that often get thrown around and interchanged, but they are actually not the same thing and have different purposes.

What Is a Solar Generator?

A solar generator is a portable power device that works similarly to a traditional generator but uses energy from the sun instead of gas. It tends to be more environmentally friendly and safe as well, as you don’t have to worry about emissions or fire risks.

These generators can be powered with solar panels that must be bought separately, but they can also often be charged via AC or DC power, such as you would get in a home or car.

There are many different kinds of solar generators and sizes, so you can get a small one to take camping, or one designed to be used in your home in case your power goes out.

They can go up to sizes that allow you to power a fridge, AC unit, or microwave if needed, but can also just be small enough to run your basic devices.


  • Designed to be portable
  • Everything but the solar panels is complete in one package
  • Versatile, can be used to charge your necessary appliances during a blackout or taken on a camping trip
  • Cheaper initial investment


  • Usually too small to completely power a whole home, even the big ones
  • Can’t customize or add more to it later
  • Don’t automatically run when the power goes out
  • Have to replace the whole system when one part goes out

What Is a Battery Bank?

Battery banks are when you connect two or more batteries into one large system by running them in series or parallel, or a mix of both if you have enough batteries. These take up a lot of space and are heavy because they have so many components.

Battery banks are much more stationary and are often built into homes to connect to a solar system mounted on the roof or property. Their most common purpose is to be used during emergencies for backup power, or to reduce the dependency on the grid during cloudy days or at night.

However, they can also be used to allow you to go completely off-grid, especially if you have a large enough battery bank. The size and strength depend on what you can afford, the space you have, and the amount of power you use daily.


  • Can start small and increase later to make it more affordable
  • Allows you to monitor power usage
  • Is installed in your home and will power all of your devices automatically when turned on
  • You can customize it to your needs
  • Cheaper in the long run, as you can replace individual parts instead of the whole system


  • Takes up a lot of space
  • Large initial investment
  • Is really only stationary, and can’t be taken everywhere
  • Have to usually leave behind if you move
  • Is just a battery bank, so you have to buy all the additional components as well
