7 Best Solar Generators for Backup for 2022

Psst! Switching your bank can help fight climate change!

January 1, 2022

Off-grid living sounds pretty inviting, especially in a world where technology and social media dominate our day to day. They are also handy tools to keep around for emergencies and are used as an alternative power source.

You have the portable solar generator options that are more easily transported and are much quieter than regular ones. However, most options on the market can function as a power station that can be charged through solar power, a regular ac plug, or a CIG port.

The big question is, do you need a solar generator? Just because you don’t live an adventurous life that takes you off the beaten path, a solar generator can still come in handy in times of crisis.

Our Top Pick: Ecoflow Delta (Best bang for your $)

Reasons for a Backup Generator

1. PG&E Shutoffs (PSPS - PG&E Public Safety Shutoffs Backup Generator)

There are many reasons why PG&E may temporarily shut off power. Depending on where you live, you may be faced with severe weather conditions, fire threats, or other natural or man-made issues that may threaten public safety.

If the location of a part of the electric system is at stake, PG&E may decide to shut it off. In these cases, having a backup solar generator won’t leave you in the dust. You will still have access to power to charge your devices.

2. Power Outages During Wildfire Season

Most of us are familiar with the wildfires that devastated California last year. In these extreme cases, power outages can be inevitable. For this reason, the presence of a solar generator can offer you access to electricity regardless of outside conditions.

3. Hurricanes

Unfortunately, for some southern USA states, hurricane warnings come every year. Only a few of us have lived through the full impact of these storms, and many of us will say we wish we had access to electricity.

A preventative measure for when the next hurricane hits is to invest in a solar generator. This way, the machine can keep you protected during a storm.

4. Blackouts in General

Blackouts happen sometimes due to the failure of power grids. You can never really predict when they will hit, so to have a backup solar generator means you will always be ready.

5. Preserving the Contents of your Fridge

Solar generators come in different sizes and can keep small items like lightbulbs running to powering all your appliances. To guarantee the safety and freshness of the food in your fridge, a solar generator can keep things cool during a power outage.

6. Keeping Your Wi-Fi Working and Your Phone Charged

During disasters, people fear for the safety of their loved ones. Having working phones and computers is essential to reaching out to family and friends. A backup solar generator will keep your Wi-Fi running.

Originally launched on Kickstarter, this is a great backup generator with a very high max output in the kilowatts. Very strong inverter is the main selling point here.

The backup generator has three rechargeable modes: with the lithium battery, solar panel or AC wall adapter. It doesn’t matter where you are, you never have to worry about running out of juice.

Benefits of Solar & Battery Powered Generators VS. Gas Generators

1. You Can Run Them Indoors

Since solar powered and battery powered generators are environmentally friendly and do not generate toxic fumes, they can be placed indoors. This means no running out in the cold and rainy weather to get them started!

They can be placed strategically and since the panels are portable, you can reposition them to optimize sunlight intake.

2. You Never Have to Buy Fuel Again

Solar powered generators do not require fuel as gas generators do. They get their power from electricity or the sun, so you never have to fear running out of power.

3. They are Noiseless

One big and very appealing benefit of solar and battery powered generators is their quiet operation. They are silent and will not permeate the room with loud background noise like gas generators do.

4. Portable

You can take solar and battery powered generators with you on a camping trip or set them up in your RV. This way, you will have access to electricity no matter where you go.


Is this good battery backup for an apartment?

Yes, if you purchase one with a compact size, a solar powered portable generator is a great option as a backup power source for an apartment.

Are these good temporary solar panels for renters?

Yes, a backup generator with solar panels for recharging is a great temporary solution for renters. It can even help save on your utilities bill over time (though the savings will be small due to the small system size). You can then take it with you when you move, unlike a solar panel that is attached to your roof.

What if the power goes out?

When the power goes out, a solar powered backup generator can provide a quick and easy solution until the issue is fixed. Solar-powered backup generators can power most household appliances and give you access to the internet during emergencies.


There is no debate that a backup generator is essential to shield you from the effects of power outages. It’s difficult to estimate how long power outages can last, especially if it’s due to natural disasters. In this case, a solar powered backup generator can power your home until the issue is solved.

Backup generators can preserve the contents of your fridge to keep your family fed, power regular appliances such as microwaves and TVs as well as your Wi-Fi router to ensure you can communicate with the world in the case of emergencies.
