In this review we will be comparing solar generators, like the Anker Solix, to gas generators, like the Predator 5000 as a backup power solution. Initially we assumed that solar generators would be the obvious choice, with their noiseless operation, unlimited solar energy, and lack of fumes or emissions. However after testing both out on extended camping trips, our perspective became a little bit more nuanced, and there emerged a new solution as the clear winner. Keep reading for our full list of pros and cons of each generator, as well as which we think you should keep on hand for your next outdoor adventure or in case of a power outage!

Pros of Solar Generators
Unlimited Power: As long as there is sunlight you can make your own power! Most people running gas generators aren’t able to make their own gas, so this is a clear win for solar generators.
Noiseless Operation: Solar generators make zero noise, except for a quiet, humming fan that occasionally turns on if there is something with a large power draw plugged in. This is a huge benefit when using a generator indoors, and also won’t draw attention to you during times of crisis.
No Fumes: Solar generators can be safely operated indoors, as they produce no harmful emissions.
No Fuel Storage: The generator stores all of its fuel (electrons) within itself, so there is no need to carry around extra fuel or gallons of gasoline.
Minimal Maintenance: Solar generators require very little maintenance, which is limited to periodic charging and discharging of the battery.
Cons of Solar Generators
Big Upfront Cost: Initial cost of solar generators are much higher compared to gas generators, but prices are decreasing across the board with ongoing technological advancements.
Sunlight Dependency: Charging depends on sunlight availability, which can be inconsistent or limited, depending on where you live or the time of year.
Variable Solar Panel Efficiency: Solar panels don’t operate at full capacity due to various factors like weather conditions, placement angles, and ambient temperature. All of these things will affect how much power you are getting from the panels.
Overall Low Power Output: You’d be surprised how large of a solar array you need to keep a generator charged or an RV running. For example, a Class C RV with one AC unit draws around 4000W. To collect that much from sunlight, you would need around 378 square feet of solar. Most fold-out solar arrays generate between 200-400W of continuous power, which is barely enough to charge two or three laptops.
Pros of Gas Generators
On-Demand Power: Recharging a gas generator takes less than 5 minutes, compared to multiple hours with a solar generator. If you have a gas station nearby, keeping the gas generator topped up with fuel is effortless and relatively cheap.
Lower Upfront Cost: Gas generators have been around longer, they have had a lot longer to streamline their manufacturing and products, and the cost is much cheaper than a comparable solar generator + solar panel setup.
Fuel Options: Dual-fuel or tri-fuel generators offer flexible options for fuel choice. Some generators will accept either natural gas or gasoline.
Cons of Gas Generators
Noise: In a time of a prolonged power outage, a gas generator is a constant audible reminder to anyone nearby that you have a portable source of power.
Fumes: Gas generators produce emissions including carbon monoxide that can be hazardous or even deadly if not managed properly.
Fuel Dependency: You are limited to the fuel you have on hand, and in a disaster situation, locating more fuel can be a significant issue. In times of crisis, if electricity is limited, gas stations might not have power in order to run the gas pumps to provide fuel.
Maintenance: Gas generators require regular maintenance, tune-ups and repairs from someone with technical skills to keep operating smoothly.
The Freshly Charged Take – A Dual Approach
When the grid goes down, solar generators like the Anker Solix can be used indoors and they can harness power from the sun, using panels outside. Gas generators must be kept outside due to carbon monoxide risks. So, what is the ideal backup power solution? The obvious answer is both, if you can afford it. The ideal scenario would be using the gas generator only to power the solar batteries, which can then be used for extended periods of time to keep other appliances up and running. Charging the solar generator with the gas generator is much more effective and quicker than using solar panels, especially in a time crunch.
