Best Portable Solar Generator for Preppers Under 30 Pounds

If you are in a hurry and just want to find out what the best portable solar generator is, then we recommend the Renogy Phoenix 210Wh Portable Generator as the best one.

Initially the Renogy Phoenix seems small for a solar generator. However, it is the most portable system we could find. It’s also the only “all-in-one” design we could find. Mainly due to its built-in solar panel. All other solar generators reviewed require you to grab 2 items, both the solar generator and the solar panel. This is the primary reason for the Renogy being our choice for the best portable solar generator available.

The Renogy also has a compact size that resembles a large briefcase. When opened up the generator looks more like your changing the DEFCON level then charging a phone. The generator is built with quality, backed up by a strong warranty,  and has all the standard features the competitors have.

A solar generator is the superior choice for camping and prepping, over a gasoline generator. Solar generators are perfectly silent and do not draw attention. As long as the sun shines you will have fuel and can store up electricity. Finally, solar generators can get as small as just 12 lbs.

A portable solar generator in the simplest terms is a battery light enough to carry that can easily be charged by a solar panel. So, for portability sake we only compared solar generators that are under 30 pounds and that have a built-in solar panel or a solar panel designed to also be portable.

In this article we will review the following portable solar generators:

Built-In versus External Solar Panel

A built-in solar panel dramatically improves the portability of a system, however is also limits the size of the solar panel. Having a solar panel separate, gives you the option of only having to carry the generator when you are not charging. This dramatically reduces your carrying weight. To compare, the Renogy (built-in panel) weighs 12lbs, where as the Jackery 160, with no panel, weighs 4.5lbs and the Jackery 240, with no panel, weighs about 7lbs.

Of the solar generators reviewed only the Renogy has a built in solar panel. To compensate for the limited size of the built-in solar panel, Renogy has added the option of adding an external solar panel.

Battery Type

You will want a model that uses Lithium batteries. Lithium-based batteries are currently the most affordable battery type for light weight, maximum storage capacity, and high continuous output. All the models reviewed use lithium batteries.

Battery Capacity

Measured in Watt-Hours (Wh), this rating tells you how much energy the battery can store. Its based on how many watts could be output for 1 hour. So a 16oWh battery can provide 160 watts for 1 hour. If you only draw 10 watts the battery should last 16 hours (10 watts x 16 hours = 160 Watt-Hours).

This specification gives you a way to estimate how long your solar generator will last. Take the wattage your device uses. Usually this value can be found on the power supply for your devices. If you have multiple devices, add up the wattage of each. Divide the wattage by the Watt-Hour rating of your generator. This will give you the hours. Since no systems is 100% efficient multiple your hours by .8, or 80%.

Portability – bugging in or out, on foot or by vehicle

If you plan on bugging out and carrying your generator by hand, you should stick with the smaller systems. For instance, the Jackery 160, the Renogy Phoenix, and the Jackery 240 all weight under 15 lbs, including the solar panel.

If you will be carrying the system in a vehicle or your plan is to bug in, any of the system reviewed here will work. Just remember if you leave your vehicle behind you will need to carry your generator.

Charge Time

Charge time is a function of the size of the battery and the size of the solar panel. To create the table below we simply took the size of the battery (Wh) and divided it by the solar panel watts. We then assumed most systems are around 80% efficient. We then double checked our number with the manufacturer specifications to verify the numbers.

For all the hours in the green boxes the manufacturer sells a solar panel to create the setup.

Solar Generator Estimated Charge Times

Extra Solar Panel

Only two of the systems allow for the addition of an extra solar panel, the Renogy and the Goal Zero. This gives these generators more flexibility in what their charge time will be and the overall weight of the system. Some system are only effective with the specific sized solar panel. Any smaller and it won’t charge the battery, any larger and the charger will shutdown due to being over powered.

Solar Panel Size

The exact size of solar panel isn’t as important as the panel being properly sized to the generator. A solar generator should charge to a level that is useful to you in around 6-10 hours, or 1 day. This way you can get a full charge each day and you are not carrying extra and unnecessary weight due to an over sized panel or generator.

Pass-Through Technology

Pass-Through technology, or intelligence as some manufactures call it, is the ability to use the solar generator while it is charging. This allows you to not only use electronics while the solar generator charges, but allows allows you to charge your electronics.

Generators with this technology and the ability to add an external solar panel gives additional options. The generator can become a  power station during the day with an extra panel. If you don’t need that much power level the extra panel behind.

Pure Sine Wave

When the AC output has a Pure Sine Wave output it means the electricity is clean and comparable to utility power. The advantages of pure sine wave power allow motors to run faster, quieter and cooler, and fans, fluorescent lights, TVs, and radios have reduced audible and electrical noise. All the generators reviewed provide pure sine wave AC power.

Jackery Portable Power Explorer Series

The Jackery Portable Power Explorer series of solar generators provide the most variety.

Jackery 160 +50W Panel Jackery 240 +50W Panel Jackery 440 +100W Panel
The Jackery 160 combined with the Jackery 50W solar panel is the smallest solar generator reviewed, based on  battery capacity and output. However, the power output and capacity is still plenty for most camping activities and prepping mobile devices like radios, laptops, and lights. The idea of the extra capacity of the Jackery 240 sounds good over the 160 however the 240 is only capable of a 50W solar panel as well. This means it will take longer to charge. Since 50W is all the 240 can handle your stuck the charge time. The Jackery 440 has plenty of storage for a portable solar generator and can handle the input from a 100W solar panel. This gives it a decent charge time. The problem is that its priced in the upper end of the 400Wh+ solar generators.

Best Portable Solar Generator

We selected the Renogy as the best portable soar generator because of its features and benefits. It compact size means its easy to carry and light weight, about the size of a large laptop. Its quality and warranty means it will last over time as well as the being carried around. The built in solar panel means you don’t have to worry about multiple pieces in a rush.

The ability to expand the solar panel allows you to dramatically decrease charge time. Using the additional panel and built-in solar panel turns your solar generator into a decent power station throughout the day. This gives you the ability to charge devices and the generator battery at one time.

If you need more power we would recommend the Goal Zero. The Goal Zero has all the same benefit as the Renogy.  In addition, the Goal Zero more than doubles the storage capacity over the Renogy.
