Buyer’s Guide to the Best Solar Generators

A portable solar generator can cater to your critical household energy needs when the lights go out. While a gas-powered unit is an option, it’s loud and dirty. And when you such a generator runs out of gas, you must get new fuel.

Solar generators work by harnessing energy from the sun for making electricity.

Not only are they clean, but also easy to use, requiring no reliance on fossil fuel. If you’re thinking of getting one as a backup power supply, but you consider the technology intimidating, this section will discuss all you need to know about how they work and tips to select the best solar generator for you & your family.

How solar generators work

While solar generator tech isn’t new, the notion of putting compact components in a portable unit is (at least relatively). These devices are similar in construction to large systems.

However, they’re small enough to just have on standby in case of emergencies or to take on the road when you’re unable to get an expensive backup power supply.

All solar generators come with the following basic components:

  • Solar panels for converting sunlight into electricity
  • A battery for storing power
  • A charge controller for controlling the current flow to the battery
  • An inverter for converting power from the battery into the type of current that’s required to power household appliances.

Tips to Select the Best Solar Generator

Making the best choice of a solar generator for your home or RV takes more than a price comparison and going through solar generator reviews. Due to the fact that the needs of everyone vary, rating a generator as the best is like comparing apples with oranges.

When trying to choose the best solar generator, the first step is to know how much power you require to run those devices, which are important to you during a power outage.

The average home in the US consumes around 25,000W of energy daily or 1000W per hour. A good number of solar generators can supply 900–5,000W of electricity each hour, which makes them appear capable of powering everything, including your freezer, TV, pool, etc. However, unlike gas-powered generators producing a steady supply of electricity so long the tank is full, solar generators can’t deliver power at that fast rate. They work on energy that’s stored in batteries, which have to be recharged between uses.

The important thing as regards getting the best solar generator (and generators generally) is to figure out how much power you require, your budget, and what specific features you consider the most crucial.

Things to Look For in Your Solar Generator

Whole home solar systems that come with many roof-mounted panels & large battery banks are able to keep things running around your home seamlessly.

What these do panels is to collect more energy for starting with, and as some of several batteries are getting drained, others are getting charged. This provides you with a reliable and consistent power supply, which can run everything your household requires.

There’s no portable generator that can realistically store enough electricity that can power every appliance in your house. However, for emergency use or on-the-go power, portable solar generators are relatively cheaper and easy to store.

Also, they can meet at least your most basic power-related household needs.

When shopping for solar generators, you need to take these factors into account:

Solar Panels

Watts is also one of the units of solar panel energy production as the watt rating on your panel multiplied by the number of hours of sun exposure it receives daily will give the total number of watts that it can generate each day. For instance, a 150W solar panel receiving 6hrs of the sun will generate 900W of power for that day.

However, things aren’t so simple with the sun since day-to-day & seasonal sun exposure changes are noteworthy. Even the best solar panels produce only limited power during cloudy days.

3 types of common solar panels are available, and their efficiency will determine the number of watts they generate for their size. Here are these 3 types of solar panels:

  1. The most common type is monocrystalline panels. These are designed using single-crystal silicon wafers. They’re somewhat more efficient in comparison with the polycrystalline type. However, they’re slightly more expensive.
  2. Polycrystalline solar cells are produced from melted fragments of silicon. Since electrons move less freely between fragments, the solar panels come with a good yet slightly less efficient rating. The difference between monocrystalline panels and polycrystalline panels for most systems is statistically not significant.
  3. Thin film, or amorphous crystal panels that make use of relatively new technology. While these panels are light, flexible, slim, durable, and inexpensive, they’re only half as efficient as their monocrystalline counterparts and need twice the footprint for producing the same amount of power. So, they’re less useful for small portable generators.

Type of Battery

There are different styles of batteries. However, the 2 most common types are lead-acid and lithium-ion. Let’s take a brief look at each of them:

  1. Lead-acid batteries, like those utilized in your car, are the most common type. They’re also the least expensive. While they’ve a shorter life span, they’re a cost-effective option for home use. In some styles of battery, you’ll find the use of special gel for enhancing their lifespan & safety; however, the power performance is similar. Further, deep-cycle batteries, which can handle repeated heavy discharges, are longer lasting, and under nearly all conditions, they’re worth the additional cost.
  2. Lithium-ion batteries, which are the battery type powering the majority of cordless tools, are lightweight and compact. Also, they’ve a longer lifespan in comparison with lead-acid batteries. Lithium-ion batteries are increasingly popular in portable solar generators due to their size and weight, even though they’ve a higher price.

Power Rating & Battery Capacity

Battery capacity represents the total amount of electricity a solar battery is able to store but doesn’t show how much power it can generate at any given moment. For that, you’ll have to check the power rating of the battery.

Generally, a battery that’s a high capacity and a low power rating will offer you less electricity, but for longer periods. And the converse is also true.

Bear in mind that solar generators operate on stored energy, and a system can contain enough panels for generating a thousand watts of energy. However, if the battery only stores 500W, that’s the maximum amount of power you’ll get without adding more capacity.

Also, it’s pertinent to keep in mind that only the best solar generators come with batteries, which can be charged simultaneously while it’s in use. This feature is known as trickle charging. Unless you’ve multiple batteries that can meet your power needs over many days, you’ll need to consider this feature vital.

If your battery requires less than 8hrs to recharge, an average portable generator that features the trickle charging option should supply consistent power and replenish itself on only solar power. If the trickle charging capability isn’t available, you won’t have power for as long as it requires to recharge your battery.

The majority of portable generator components are sized for maximizing the capacity of each to aid efficiency. By expanding one component, you’ll usually have to upgrade others. However, the crucial part is, better systems are expandable for meeting changing needs.

Power Inverter Rating

This shouldn’t be confused with a battery’s power rating discussed above. Power inverters work by converting the direct electrical current (also called DC), which comes out of the solar panels, to the alternating current (also called AC), which your appliances require. AC is the same type of electricity coming from your wall outlet.

Inverters have a watt rating that shows the maximum power they can take. It should always be at least the max amount of power, which the system is able to produce.
While pure sine wave inverters are expensive, they’re more efficient and bring about less wear on certain appliances, such as televisions, microwaves, and CPAP machines. However, they’ve double the cost of modified sine wave inverters, and that may not be a cost-effective option for occasional use.


The weight of a portable solar generator varies from as little as 20 pounds to as huge as 200 pounds. Weight mainly comes from the panels as well as the battery.

You’ve to note that panel weight is hard to change significantly without getting lightweight frames. Also, other components compromising durability & lithium-ion batteries are much lighter in comparison with lead-acid, but they’re expensive.

The major point about portability more often lies in the manner the weight is distributed, instead of the individual components. You’ll find parts layered in a sturdy and wheeled box easier to manage than separate pieces. Also, solar panels, which fold like suitcases, reduce bulk. This makes them easier for you to handle at the same weight.

If you know that your system will be staying fairly stationary, you’ll have to always take weight into account, but it’s not much of an issue.

On the other hand, if you’ll be moving it daily, then note that lightweight systems will spare your back and will face less risk of getting damaged during moves.
