How Did We Review Each Solar Generator?
There are a number of factors we considered when choosing which solar power generators to recommend, including:
Battery storage capacity is an important ranking factor. A greater battery capacity means the generator can store more energy, which ultimately means it will last longer without requiring a recharge. This is measured in watt-hours (Wh).
When your generator is up and running, it will put out a certain amount of energy, measured in watts. It’s important to select a generator that offers enough watts for you to power your essential home appliances.
The inverter is a critical part of any backup power generator. Basically, this is the component that turns solar energy into AC (alternating current) electricity. Inverter rating, along with battery capacity, determine how much power you can get from your home backup generator.
In order for your backup generator to function, you’ll need some way of charging it. And if you plan to rely on solar energy, that means using solar panels.
Expandability means that you can add solar panels to your generator as needed, making it easier to absorb more sunlight for energy. You will typically need a special solar adapter cable to facilitate this, which may need to be purchased separately.
Number of Outlets
How many devices, power tools, or appliances do you need to plug in? The functionality of your backup generator will be determined by how many outlets are available.
The type of outport ports is equally important. The most common types that buyers check for include mobile device charging ports (USB-A and USB-C), AC ports (the normal household wall outlet), and even 12-volt DC ports (what you probably have in your car).
Of course, as you look for the best home backup generator, one of the most crucial considerations of all is your budget. We’ve sought to emphasize generators that offer maximum value.
Based on these criteria, we’ve determined the solar backup generators that offer the most consumer value. Check out our complete list of recommendations below.

How Does a Solar Generator Work?
Solar generators capture energy from the sun using photovoltaic solar panels, and store it in a built-in battery. Note that in order to absorb the sun’s energy, your portable generator will need solar panels.
These are typically sold separately, or as a package with the unit, so you’ll need to factor in this additional cost. Solar panels contain solar cells, which are typically made of monocrystalline or polycrystalline silicone that acts as a semiconductor.
Once the sun’s energy is stored in the battery, it is converted into AC energy. This happens via a component known as an inverter. AC power is required for most of your household appliances, as well as for charging devices like your phone, laptop, or tablet that normally require a wall charger or AC outlet.
We’ve included a short video below for a more in-depth look at how they work.
Can a Solar Generator Power My Entire House?
Generally speaking, a rechargeable solar generator won’t be able to power your entire house if you lose power. With that said, even a smaller generator can be used to power key devices or appliances, sometimes for days at a time depending on its power consumption. For instance, you can keep your refrigerator up and running, and/or ensure plenty of sustained use for medical devices, like CPAP machines.
With an especially robust generator, you may also be able to connect to core circuits, running multiple appliances at one time.
So, while having an emergency power supply from a solar generator may not mean that you can go about your life just like you would normally, you can at least keep the lights on at home, run your air conditioner, or ensure your perishable food items remain fresh until your electricity comes back on.
What Are the Advantages of Using a Solar Generator?
There are a number of advantages you can anticipate from an emergency generator, especially when you choose to go solar. Consider:
You can minimize the disruption of a power outage.
Again, inclement weather can cause power outages that last for hours, sometimes even days. During that time, you can use a backup generator to keep your essential appliances and devices up and running. This level of preparedness can offer ample peace of mind.
Solar generators offer a clean alternative to other energy sources.
Most generators are powered by fossil fuels, which means they emit a lot of noxious emissions. If you want a clean power source and a minimal environmental footprint, these solar solutions are just the ticket. They are also much quieter than traditional gas or diesel generators.
They can be very cost-effective in the long run.
While the initial purchase price of a solar generator may seem steep, keep in mind that sunlight is free. You don’t have to worry about buying fuel or any additional expenses associated with your solar unit.
Find the Solar Generator That’s Best for You
Disaster preparedness begins by identifying a reliable power source, and if you want that power source to be clean and renewable, solar generators are ideal. Take a moment to explore the options and find the generator that’s right for you.
In addition to the criteria we used to review solar generators, you may also want to consider the following when selecting a model:
