Best off-grid solar system in 2022

Many consumers are interested in home solar panels because they want to live off the grid. Residential solar systems can increase your energy independence while also helping to lower your energy costs and decrease your carbon footprint. There are certain benefits of an off-grid solar system, including significantly lowering (if not eliminating) your electricity bill and protection from power outages.

Finding the right off-grid solar kit doesn’t have to be complicated. Here are our picks for the best off-grid solar systems in 2022:

  • WindyNation 400W Kit
  • Renogy 100W Solar Starter Kit
  • Eco-Worthy 200W complete solar panel kit
  • Eco LLC 2,000W 48 Volt off-grid solar system
  • AltE 1,980W “tiny house” base kit #3

Understanding your energy usage is key when searching for an off-grid solar system. You can use the SaveOnEnergy usage calculator to estimate your household energy usage.

The average household uses about 893 kilowatt-hours (kWh) every month. This averages out to about 1,223 watts (W) per month. There are 1,000 kilowatts in a watt and 730 hours in a month. Here is how we converted kilowatt-hours into watts.

893 kWh X 1,000 / 730 hours = 1,223 W

It’s important to keep this in mind because most off-grid solar kits measure their power output in watts instead of kWh.

Before choosing your off-grid solar kit, you should also think about your energy goals. Do you want to power your entire home with your off-grid solar system? If so, you will need to invest in a kit with a larger power output. If you only need to power an RV, boat, or just a few devices, you could choose a kit with a lower power output instead. The prices included in these reviews are accurate at the time of publication.

Find the best off-grid solar system

Solar systems are comprised of several parts, possibly from different manufacturers. The best off-grid solar system is one that works for your needs. The most common parts that make up an off-grid solar system include: 

  • Solar panels
  • Solar inverter
  • Solar battery
  • Charge controller
  • Cables and wiring components
  • Mounting equipment

Thankfully, some manufacturers offer off-grid solar kits that include all of the necessary components for an off-grid system.

How to choose the best off-grid solar system

Before purchasing an off-grid solar system kit, there are a few things you should consider. 

  • System size. It’s best to have an idea of how much electricity you’ll need before choosing an off-grid system. Look for systems that have a power output similar to the amount of electricity you use every month or allow you to expand the system if you need more solar panels to meet your needs.
  • Battery options. Off-grid solar systems rely heavily on battery storage because they are not connected to the power grid. Storing excess electricity in a solar battery will provide you with electricity when your panels aren’t generating power, like at night or when it’s raining. Some off-grid kits include solar batteries, but others do not. 
  • Warranties. Most manufacturers in the solar industry offer warranties on their products. Material warranties cover any defects to the products. Solar panels also usually come with performance warranties, which guarantee the panels will work efficiently.
  • Customizable solar kits. Some off-grid solar kits are more customizable than others. There are several options on this list that allow you to add different types of solar batteries, inverters, and mounting equipment. There are also expansion kits that some manufacturers offer if you later decide to expand the size of your off-grid solar system. 
  • Your location. Where you live will have a big impact on whether an off-grid solar system is the right choice for you. In some states, it’s illegal to disconnect from the power grid. If you live in an area that doesn’t get much sun, only receiving your electricity from solar power might not be the best option and you may want to consider a hybrid solar system instead.
