Are You Looking For the Best Solar Generator?

Either it is because you need an emergency power supply to fence off against the incoming hurricanes in your areas. Or it is just because the mainline electric bills are sometimes uncomfortably high for your budget. You have come here to look for the best solar generator – and a good one at that.

But for those who need a reminder of what you are investing your money into, there are a plethora of benefits. It would be granted to you immediately upon owning a solar generator.


The first and best of all, of course, is the free power that you would have just putting the best generator itself out into the Sun for a couple of hours.

Secondly, solar generators are friendly to the environment.

And third, as we have explained above: Solar generators do not rely on any fuel at all. Unlike traditional generators running on gasoline or kerosene to provide electricity. The fuel that runs a solar generator is constant and ubiquitous everywhere without shade: Sunlight.

As long as you have direct sunlight coming down on the panels, you have power. That is a plus considering the old-as-history struggle of carrying gallons of fuel on a trip to run a generator that drinks fuel faster than a drunkard on his prime day.

Who Can Benefit from a Solar Generator

Anyone can benefit from a solar generator! It can be used to supply power to mundane appliances such as cookers, fridges,… to charging electric wheelchairs for the disabled. And in the very long term, a passive benefit for the entire planet from the generator’s innate eco-friendliness as well.

The Basics of Using The Best Solar Generators

Panel Types

The photovoltaic (PV) or just solar panels made up the heart of a solar generator. Without these PV panels to catch incoming sunlight and transform the heat into usable power, even the best solar generator would be useless.

With that said, there are three types of PV panels. The difference is the material that they are respectively made out of. Monocrystalline Silicon (mono-Si), Polycrystalline Silicon (poly-Si) and Amorphous Silicon (a-Si).

For mono-Si panels, they produce the optimal amount of power relative to their size – and thus, they are considered to be the best PV panels available out on the market.

Next came poly-Si, which is employed in larger panels.

And lastly, a-Si. Although a-Si is the underdog compared to the two other materials. It provides much more power than the rest under indirect sunlight (Producing power without a direct line of sight with the Sun).

Battery Storage Capacity

When you produce all of those power, they need a reservoir to be kept securely in and maybe tapped into later when they are needed. This is why battery(is) is/are also an integral component of a solar generator. And the batteries are also one of the criteria that make a model the best solar generator or else.

Emergency or backup solar generators that are expected to keep a charge for a long while in case they are often needed have a deep-cycle battery (Or marine battery) at heart. These lead-acid batteries can sustain a charge for far more longer than a car battery.

However, they are certainly not the best fit for the job. Nowadays, the title for solar batteries has been handed to Lithium Ion batteries. They can hold larger, go through more circles and sustain longer charges.

Solar PV Input

To maximize energy production, you have to ensure that the panel has as clear a line of sight with the Sun as possible. Solar panels are extremely sensitive to the intensity of sunlight, even a slight decrease or shading of the Sun would affect the power output of the panel dramatically. Some panels would drop its output even if the shadow is a bird or a passing cloud – those are referred to as ‘Soft’ obstructions.

Vice versa, ‘Hard’ obstructions are objects that block sunlight from reaching the panels such as a building, a column, or a chimney. If the panel is shaded enough, they will stop producing power altogether. And they will also strain themselves to produce power, which, not only does not do any good, but it will also drain out your battery in the process.

That is why before you do anything with a solar generator, the first thing to take into mind is where you should put them.

Component Quality

Besides all of the specifications and the environments, there is the hardware. That is the universal law of all things appliances. The better the components that made up the machine, the better it would function.

When we are looking for the best solar generators, it is important to look into the quality of the components from the panels, battery, down to the inverter. The panels should decently produce power higher than the average of their size; the battery should hold a large enough charge for a long while,…

Solar generators – for whatever purpose that you have in mind for them, whether it is for emergencies or long trips, must be portable enough for you to lug around at a certain limit comfortably. Of course, it’s not going to be easy to carry the entire machine. However, they must have a reasonable mobility to them.

Power Ratings in Watt

The critical core of the best solar generators is here: The power rating. The best solar generators would be those who could produce the most power. While at the same time, be at a reasonable price, an adequate level of maintenance and complexity expected of them. The average American household consumes roughly 1,100 watts per hour. That would be far more than a simple solar generator (Not a full-fledged solar power system) to provide.

However, for simpler purposes such as an emergency backup generator, where power ration is expected or while camping, solar generators would do their job well. They are also effective where limited power usage can be observed. But no matter how light the demands from them are, you would want to get the best out of every single solar cell.

Solar panels often come with 100-watts panels all the way to those that can produce 300-watts on a sunny, hot day. The more power you need, the more expensive they would be in the end, as a result. So it’s most important to consider the purpose that you’re having them before you finally decide on the procurement.

3.7lb 500W 288WH Backup Portable Generator Solar Power Source Power Inverter

This is the true monster of a generator for all of your emergency preparations needs or when you’re expecting to face rough nature on a long trip ahead. As the EasyFocus’ generator is jam-packed with features and strongly built to withstand anything next to the Apocalypse itself.

For the EasyFocus, you would have an entire 288Wh of charge to yourself – almost twice the capability of the PAXCESS that we had set out the list with. It also comes with more than a dozen of different outlets to suit your power needs accordingly, including four USB ports, four 12V DC ports, and finally, three 120V AC outlets with a solar input socket. The multitude of ports would come in great handy and would help you in utilizing the entire bank of power within the generator to the best effect.

For emergencies, besides all of the ports, the generator also has a torch built within.  This could be turned on with a switch to help you navigate in the dark if you don’t already have a torch with you. And of course, without the multiple safety mechanisms that keep the generator in check, it would not make it on the list at all.


  • Extremely large battery bank.
  • Strongly built.
  • A wide assortment of ports.
  • Built-in emergency torch.
  • Integrated safety mechanisms.


  • Inadequate cooling.
  • Constant power loss due to the same cooling problem.


Designed as a true emergency generator, it is ruggedly built and proved to be able to withstand the harshest thing thrown at it. The colossal amount of charge it can carry at once sweeten the deal considerably. And add in the hosts of features it provides, this is certainly one of the best solar generators in the market.

4.Solar Generator 2500 Watt (2) 100 Watt Solar Panels + BatteryMINDer Charger!

While the three previous generators are part of a complete system, which means they lack the actual power generating solar panels that would be sold separately. The BePreparedSolar’s generator is the complete system in a single package.

Along with the atypical systems found in the rest of the generators on the list such as the Battery Management System, the peripheral connection ports,… The generator also features a 100Ah deep-cycle (Marine) battery, as said above, that can store power much longer and more reliably than other types. For example, it can store power much longer than lithium, which is used for more rapid tasks.

The complete base model also comes with two 100W solar panels along with 30 feet of cables to set them up along with the generator to begin producing power immediately. This is the quickest way to begin, as for other generators you would have to find compatible solar panels. This way, you can go hand to hand with them and the appropriate wirings.


  • Attached solar panels.
  • Long-lasting deep-cycle battery bank.
  • Great digital controls.
  • Wide port selections.


  • Quite expensive at-once.
  • Reduced mobility due to the weight.


It lacks the mobility that would be needed from an emergency generator even though they tried to remedy this by adding a set of wheels. If you’re expecting something extremely portable that you can bring with you through rough terrains, this is certainly not it.

But if you’re looking for a quick and robust backup power system, this is the best solar generator for you.

5.Coolis 150Wh Portable Solar Power Inverter Generator

The Coolis is the most portable generator on the list at the size of basketball. And it weighs 2 kilograms total, making it the on-the-run generator for your consideration.

With the normal must-have features of a good generator laid out: The BMS system, an electronic control screen and the full quantity of ports. It totes a 1.5-kilogram lithium battery capable of holding 150Wh of charge, the same as the first generator on the list – although much smaller and compact.

It could be charged using the three different methods from the normal wall outlet, car’s battery, to, you guess it, the solar panel. However, you would need to find an MC4 adapter for your panels to fit with the generator itself.


  • Compact and light.
  • Digital control system.
  • Selections of ports.
  • Li-Ion battery bank holds enough power on the run.


  • MC4 adapter is separated.


For an off-the-grid generator that can provide immediate energy on the run, it is extremely compact and small. It can fit snugly in a backpack and would also output the necessary power you would need in a short while. Coupling with a mobile solar panel, you won’t even have to worry about running out of charge during the day while sacrificing mobility.


For powering needs, solar power takes the cake for being the most convenient and flexible power producing methods there are. It can be used anytime as long as there is sunlight. Therefore, it is extremely handy to have a solar power kit in case you need it the most when traditional methods fail on you.

We hope this list gives you an inkling of what you’re looking for!
