The Best Off Grid Solar Systems for RV, Boat & Small Home

best off grid solar system

Cutting yourself off from the power grid has many benefits. First off, you’ll be more self-sustaining and won’t have to rely on someone else for power generation. You also won’t have to worry about electricity bills piling up since the renewable energy from your solar panels will be free.

To live life sustainably and away from the grid, you need to find the best off grid solar system. Your system should have panels to absorb and convert solar energy into free energy for you to use at home, whether for appliances or lighting.

But how can you tell which off grid solar power systems for homes are the best? Here are a couple of factors you should look out for when buying an off grid solar system:

  • Emits an adequate amount of power: The solar system you buy needs to be proportional to the size of your house and how much energy you and your family consume. If you have a smaller home, you can get away with a 5KW solar system off grid. If you have a three-story home with many big appliances, you might consider the 10KW off grid solar system price option, even if it can be a bit more expensive.
  • Complete with accessories: You must ensure that your complete off grid solar system comes with all the necessary components it needs to run properly. These usually include several solar panels, a junction box, a charge controller, cable connectors, mounting brackets, and more.
  • Solar panels have high conversion efficiency: Go for panels that can give you the highest energy conversion rates. Try purchasing solar panels made with monocrystalline solar cells, which are known to be very efficient in absorbing light energy. This will allow you to make the most out of your stand alone solar system.

Of course, these are just some of the factors you need to consider when shopping for the right off grid power systems. For other things to look out for, check out our buying guide below.
