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

Written by K. Miller / Fact checked by J. Fussell

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.

What to Look for When Looking for Off Grid Solar Systems


Has a significant number of solar panels that can power up your whole place

More often than not, one solar panel will not be able to cut it when it comes to powering up an entire home. Make sure the off grid solar systems you’re eyeing come with enough solar panels to power up all your home’s appliances and lights.

Designed with solar panels that are durable and high-quality

Always go for solar panels that are durable and sturdy. Check out those with multi-layered sheets for extra lamination and protection from the elements. You’ll also want a solar panel with corrosion-free aluminum framing to resist impact and damage, therefore extending the lifespan of your solar system.

If you’re not sure whether a solar system you’re eyeing is sturdy enough, you can always check out simple off grid system reviews left by other users to see their experience with the system’s longevity.

The off grid solar system shouldn’t be complicated to set up and install

If you’re a newbie in setting up off grid solar systems, save yourself the hassle by going for easy-installation solar panel kits.

Go for those with easy-connect cables or panels that have pre-drilled holes to make mounting quick and convenient. Another thing that might help is longer connectors to give you the mobility to set up anywhere you want.

Components should be waterproof to prevent damage from the weather

When looking for a complete off grid solar system with batteries, it would be good to see that each component is waterproof-grade, not just the panels. That means even your junction box and cables have to be waterproof so as not to get damaged during tough weather conditions.

Off-grid systems should work efficiently even when it’s cloudy outside

One con of going off the grid and relying solely on renewable energy for your electricity is not having backup power when your area is less sunny than usual. Make sure your solar system is built to work efficiently even when the sunlight is a bit dimmed down.

Look for solar panels with bypass diodes that allow them to provide energy without drops in power, even in shaded, low-light areas.

Can a House Run On Solar Power Alone


Yes, a house can definitely be self-sustainable by running on solar power alone. High-quality off grid solar system packages with a significant number of solar panels can provide enough energy to power up all your lighting, appliances, and other electrical needs.

However, you must remember that installing a solar system from the ground up can be difficult and a bit expensive. You’ll have to invest in multiple solar panels and make space on your roof or balcony to mount them.

Installing an off grid solar panel system also requires you to set up all the necessary junction boxes and controllers inside your home, which can be quite tedious. You can choose to hire a professional to help you out with that if you’re not entirely comfortable doing it yourself.

If you feel your house needs more power than just solar energy, you can look for off grid solar and wind power kits. Wind power is another efficient source of renewable energy, although solar power remains the gold standard.

How Big of a Solar System Do I Need to Go Off Grid

It depends on how big your home is and how much electricity you and your family need to use. For a family of two or three in a small bungalow, you can get away with just several 250W solar panels. But if you have a bigger home with more floors, you’ll definitely need to invest in about 10-15 panels to get the energy you need.

Before thinking of off grid power solutions, always assess how much energy you need to get your home up and running in the first place. Otherwise, figuring out which off grid battery system to get may be tricky and confusing.

How Much Does an Off-Grid Solar System Cost

The price of your off grid solar system will depend on how much power it emits. For example, a system that emits a thousand kilo-watts will be less expensive than the more powerful 5KW off grid solar system price.

A small off grid solar system can go between $500-10,000, depending on how many panels you use. For bigger homes that need more panels and accessories to complete the solar system, you may have to spend more money. You can even pay around $40,000 for a home that needs a 20KW system.

Yes, these prices seem a little hefty. But remember that it’s an investment. By going off-grid with these systems, you won’t pay another electricity bill again.

But if you want to save money, you don’t have to spend on brand new off grid solar systems. You can always look through online marketplaces to shop for a used off grid solar system for sale. However, note that you may come across issues with wear and tear if you don’t go for a brand new solar system.

Do You Have to Pay Taxes If You Live off the Grid

Living off the grid isn’t without its expenses. Obviously, you will still need to pay your property taxes and income taxes. But because you won’t have to pay monthly electricity bills after installing the top-tier off grid solar power system, you can still end up saving money.


Going off the grid is a bold choice. But if being self-sustainable and avoiding crazy electricity bills is a priority for you, purchase the best off grid solar system you can find.

Opting to go off the grid is also perfect if you’re serious about using renewable energy to do your part in reducing carbon emissions to save the planet. Next time you’re thinking of reasons to get an off the grid solar system, remember the impact you’ll have on the environment.

It’s hard to go wrong with any of the off the grid electricity systems above. They’re beneficial for homes with different sizes and energy consumption.
