Portable Solar Generators 101: How They Work, Types Why You Need One
Solar generators are becoming a popular alternative to standby and gas generators. They’re portable, use clean energy, simple to use, and can operate indoors. Read on to discover more about how your solar generator works and the different types offered by Goal Zero.
How do solar generators work?
A portable solar generator is a combination of a power station and a solar panel. The power station stores energy in batteries, and the solar panel collects energy from the sun and converts it into electricity. The solar generator can be used to provide power for disaster prep aredness or unforeseen situations.
Solar generators are an increasingly popular option for portable power, as they offer a clean and renewable source of energy. Solar generators can power small appliances like lights and phone chargers or larger devices like TVs and refrigerators.
They are also becoming more popular as backup power sources for homes and businesses in case of power outages. Solar generators can be used in various applications, making them versatile for portable power.
Types of solar generators
There are two types of solar generators : Solar Backup Generators and Portable Solar Generators.
Solar Backup Generators are permanently installed and wired to your home’s electrical panel. They turn on automatically when the power goes out and provide backup power for as long as the sun is shining.
Portable Solar Generators are small, self-contained units that can be easily transported and used in various settings. They have built-in batteries that store solar energy when there is no sunlight available.
Why do you need a solar generator?
A portable solar or solar backup generator can be a lifesaver in many situations. If you live in an area prone to power outages, having a backup generator can mean the difference between staying comfortable and safe in your home and being left in the dark.
There are many reasons you might need a portable solar or solar backup generator. Maybe you live in an area often hit by hurricanes or other severe weather conditions that can knock out power lines. Or, perhaps you are someone who likes to camp and hike in remote areas where there is no access to electricity.
Having a backup generator can give you peace of mind knowing that you have a way to generate power when the grid is down.
If you consider purchasing a portable solar or solar backup generator, you should keep a few things in mind.
- First, you will need to decide how much power you need to generate. This will depend on how many appliances and lights you need to run and how long you need to be able to run them.
- Second, you will need to consider where you will store your generator. Find a safe and dry place to store it where the elements will not damage it.
- Finally, you will need to decide how often you plan on using your generator. If you only plan on using it occasionally, then a smaller model may be all you need. However, if you plan to use it frequently, you may want to consider a larger model that can provide more power.
No matter what your reason is for needing a portable solar or solar backup generator, there are many different options available on the market today. With a little bit of research, you should be able to find the perfect generator for your needs.
Why are portable solar generators preferred?
One of the reasons portable solar generators are preferred over traditional gas generators is that they are much more efficient. Solar panels convert sunlight into electrical energy, stored in power stations for later use. This means that you can generate power even when the sun isn’t shining, making them an excellent option for camping or other activities where you might not access traditional fuel sources.
When a gas generator is turned on, it is always burning gas. It burns the same amount of gas if you charge a cell phone or refrigerator. A solar generator is more efficient because it only outputs the amount of energy your device needs at that time.
Another advantage of portable solar generators is that they are much quieter than gas generators. Gasoline engines produce a lot of noise, which can be a major annoyance. Portable solar generators run silently, so you can use them without disturbances.
Finally, portable solar generators are better for the environment than gas generators. Gasoline engines produce harmful emissions that damage the ozone layer and contribute to climate change. Solar panels, on the other hand, generate clean, renewable energy that doesn’t pollute the air or harm the environment.

As a result, manufacturers are working hard to make solar backup generators better and more reliable than their fuel-powered counterparts. This mirrors the growth and popularity of home solar power systems as an alternative to powering your home with fossil fuels.
With this article, you will better understand what a solar generator is, why solar generators are worth an investment, how to shop for a portable solar generator that’s right for you, and why solar-powered generators should replace traditional gas-powered generators.
What Is A Solar Generator?
The term solar generator usually refers to the combination of portable solar panels, battery, battery charger, and inverter into a single device that allows you to capture, store, and distribute power from the sun.
Solar generators are popular for camping trips, boating, RV trips, and as emergency backup power.
Unlike a traditional generator, which is normally powered by gas, diesel, or propane and includes an engine, fuel tank, and alternator, a solar generator lacks any moving parts. They’re essentially comprised of four elements:
- Portable Solar Panels. Captures energy from the sun
- Rechargeable Battery. Stores the energy captured by solar panels
- Solar Charge Controller. Manages how much energy goes into the battery
- Solar Inverter. Converts the sun’s energy into usable electricity
Thus, a solar generator is basically a portable battery with some photovoltaic (PV) panels attached to collect sunlight.
A portable solar generator turns out to be a great power supply, whether you’re on the road, camping, or needing electricity during a power outage. Depending upon your situation, you might want a solar generator with a variety of outlets, especially in emergencies where you have multiple power-dependent devices and appliances.
Typically, solar generators have 12-volt sockets, AC outlets, and USB ports to allow you to charge different devices. The beauty of having several charging options with your portable generator is that you can get the power you need on your terms. For example, you can plug a smartphone directly into the USB port to charge, and then connect an extension cord to the AC outlet to power a set of string lights.
In most cases, you will have the option to buy components like solar battery storage and panels separately, though you can also buy them as a complete all-in-one kit. We recommend purchasing the accessories you need to generate and store enough electricity for your intended use.
How Do Solar Power Generators Work?
A solar battery generator works by creating electricity from sunlight and storing it in a battery for future use. Here is a more detailed breakdown of the process:
- Solar panels convert sunlight to DC electricity and pass it through the charge controller.
- The charge controller regulates the voltage of electricity before storage, ensuring the right amount of current goes to the battery.
- The battery stores all the solar energy for later use.
- The inverter converts the stored energy from the battery to the AC power that most appliances and devices use.
Who Benefits From Using Solar Generators?
Solar generators don’t burn fuel to generate electricity, making them ideal for anyone looking to reduce reliance on gas-powered generators, combat blackouts and other power outages, and have a reliable backup power source option in case of emergencies.
You can use the energy stored in a solar generator during a power outage, to charge your devices when camping, and as source of energy on an RV or boating trip. Essentially, a solar-powered backup generator is ideal for a range of real-life situations, meaning it’s useful to have around for more than just emergencies.
People Who Want to Make Eco-Friendly Choices
Traditional generators run on fossil fuels that pollute the environment. If you’re conscious of the danger these fuels possess, then a solar backup generator is ideal for you.
People Bothered by the Sounds and Smells of Traditional Generators
Traditional generators are noisy and stinky because they’re combustion engines running on fossil fuels. Over time and even with proper maintenance, they can become noisier and smellier. If you’re looking for a generator that creates zero sounds and smells, a solar power generator will not let you down.
People Who Enjoy Spending Time Outdoors
You will find solar power generators are helpful if you enjoy being outside, yet still want to bring along a few modern perks. For example, during a camping or boating trip, solar batteries come in handy to ensure you have continuous power access. You could string up lights after sundown, charge your phones, run small kitchen appliances, and any number of conveniences you had to do without in the past.

Your Energy Requirements
The amount of electricity you need should be your top consideration for determining the size of your solar powered generator. For example, if you plan to use it outdoors, you should calculate how much energy your devices and appliances use when comparing the storage capacity of potential solar generators.
How Much Electricity The Solar Generator Can Provide
The longer a generator can provide power, the better. (This is usually calculated in watt hours.) Considering you don’t always know when you will have an opportunity to recharge it, it is best to have one that can run efficiently for a long time. That way, it will be easier for you to go about your daily activities or complete what you were doing, knowing you have enough backup power.
How Long The Solar Generator Takes To Charge
In addition to comparing the battery capacity of a solar generator, you should also pay attention to how long it takes for the battery to achieve a full charge. Some even have the ability to quick charge from a home AC power outlet. This will help with planning how much time you’ll need to be without power in the event a recharge is necessary.
What Features and Benefits are Included
You can do a lot with a solar generator that has helpful features. For example, more USB ports and power outlets give you the freedom to charge multiple devices at once.
Weight is another essential consideration, especially if you plan to use your generator for outdoor activities. Batteries can be heavy, so you might want to look for a solar generator that has focused on keeping the weight down if you plan to move it around a lot.
What the Warranty Covers
We recommend examining any benefits you might enjoy from the product warranty. The larger and more reputable the company, the more perks you will likely receive to support your solar power generator. The top options include replacement parts for any necessary repairs, as well as a longer length of time your solar generator is covered by the warranty.
Comparing Portable Solar Generators with Traditional Gas-Powered Generators
The Pros of Solar Generators
Investing in a portable solar generator is a good way of reducing your environmental impact and enjoying numerous other benefits:
Portable
Generally lighter than traditional gas-powered generators, solar generators are ideal for outdoor events, camping, emergencies, and general on-the-go activities. Some of them are even equipped with a luggage-like pull handle to enhance portability.
Low Maintenance
Wear and tear due to moving parts in traditional emergency generators can lead to high maintenance costs. Solar generators have no moving parts and don’t rely on gas to generate electricity. This design helps lower the possibility of having to pay for repairs.
Clean Energy
Solar generators generate clean, renewable energy that doesn’t hurt the environment when running. Traditional generators run on fossil fuels which contribute to air pollution and climate change. As an added benefit, you can access solar energy freely instead of paying for pricey fossil fuels.
Easy Operation
Solar generators are easy to use as they don’t require fueling, oiling, starting, and maintaining. Just turn it on, connect your devices, and draw power from it.
The Cons of Solar Generators
There are a few disadvantages to using solar generators that you should consider before making a purchase:
Higher Upfront Cost
Solar generators typically require a higher initial investment than traditional generators. However, the costs of operating are lower than traditional options, so you’ll save money over time.
Lower Energy Storage
Solar generators aren’t ideal if your power demands are too high. For instance, during a power outage, your generator may not be sufficient to operate all devices and appliances in your house. In most cases, they are best for operating a few devices at a time, such as lighting, a television, or a refrigerator.
Slower Energy Generation
Compared to traditional gas-powered portable generators, solar generators are not the best option when you need instantaneous power. If your battery runs out of power, you have to wait for it to recharge to get power to your appliances and devices, which can vary depending on the weather conditions. With a traditional generator, you simply need to add more fuel to generate additional power.
The Pros of Traditional Generators
Generators powered by fossil fuels do have some advantages, including:
Portability
Traditional options are available in different sizes, and there are smaller sizes that you can bring with you when traveling. Just remember that you also have to carry gasoline, so they aren’t quite as portable as solar generators.
Familiar Technology
Having been on the market for years, traditional generators are more familiar to some people. However, that market dominance also means the technology hasn’t been dramatically improved because of the lack of competition.
Electricity On-Demand
Traditional generators produce electricity as soon as they receive fuel, while a solar generator must be recharged to provide electricity. Hence, gas-powered generators are more convenient when you need instant power.
The Cons of Traditional Generators
Despite their popularity over the years, traditional generators have their shortcomings. Here are some of the reasons why people are ditching them:
Fuel Costs
Traditional generators rely on costly fossil fuels to run, which increases their long-term costs over the initial purchase price. You may also have to pay more to access that fuel if you aren’t near a gas station or other fuel source.
Toxic Gases
Traditional generators are notorious polluters. Each gallon of gasoline contains about 20.35lbs of carbon dioxide, and the average camping generator emits around 1-2 lbs of carbon dioxide per hour, even when running at 1/4 of the max rated load.
In addition to carbon dioxide, gas-powered generators can also release other harmful gases into the atmosphere, including carbon monoxide, nitrous oxides, and sulfur oxides.
Noisy Operation
Because of all the moving parts that make up a traditional gas-powered generator, they produce a lot of noise when operating. This is especially true for smaller portable generators, which are designed to prioritize size and weight over noise prevention.
Ongoing Maintenance
You have to continuously pay to take care of your traditional generator if you want to keep it in good working order. That regular maintenance occurs because the generator uses moving parts to process fossil fuels into electricity, and those moving parts need to be cleaned, oiled, and replaced over time. In addition, the fuel can go bad if it sits unused for a long period of time. Those routine costs definitely impact the total price of owning a gas-powered generator in the long run.
Key Takeaways
Solar generators are growing in popularity, and with advances in solar technologies, people who like clean energy are increasingly picking them over gas-powered generators. Solar generators offer low maintenance, portability, clean energy, and sustainable living to combat climate change. The numerous benefits of owning a solar generator make it worth the investment.
Before you buy a solar-powered generator, make sure you analyze the key features of different brands to pick one that will address your power needs. Brands like Jackery, Goal Zero Yeti, and Bluetti make a wide range of different solar generators to match your needs.
If you want to store even more backup solar power than even the best solar generator can provide, you should consider solar battery storage that connects to your home solar panel system. While your home solar panels can definitely charge your portable solar generator so you have on-the-go power whenever you need it, solar generators are not designed to act as a home standby generator for your entire home.

In this solar generator ultimate guide, we will reveal everything related to the clean power solution, the differences between solar and gas generators, and how to choose the right generator.
What Is A Solar Generator
Technically, a solar generator means a power generator that works on solar energy. It is a term that refers to the combination of portable power stations and solar panels to capture, store, and distribute the sun’s power.
Most powerful and reliable solar generators are used during RV trips, emergency power backup solutions, camping, or other outdoor activities. Unlike gas generators that require diesel, propane, or gas, a solar generator comprises of:
- Portable Solar Panels
- Portable Power Station ( including Rechargeable Battery Solar Charge Controller Solar Inverter)
Different sizes and capacities of solar generators are available, ensuring you can choose the one that suits your needs without overspending.
The Components Of a Solar Generator
Now that you know what a solar generator is, it’s time to explain the critical components of the system.
Solar Panels
Also referred to as photovoltaic cells, solar panels convert sunlight into electricity. Solar generators use portable and foldable solar panels to differentiate them from rooftop panels.
Charge Controller
When the electricity is generated by the solar panels, the first component it reaches is the charge controller (or regulator). As solar energy is generated at variable rates, the charge controller’s job is to shape and condition electricity to avoid overcharging. The highly efficient solar generators are equipped with MPPT technology that ensures nothing is damaged when power flows through the system.
Another core component of the portable solar generator is an inverter that turns direct current output from solar panels to alternating current. The job of the inverter is to draw energy from the solar system and transport it to appliances.
Solar Battery
The electricity generated by solar panels is stored in the solar battery until it’s needed. Most modern solar generators have an in-built lithium-ion battery to store current collected by solar panels.
The Usage Of A Solar Generator
A solar generator can be used in multiple ways, including but not limited to:
- Emergency Backup Supply: Frequent power outages and emergencies are the main reasons homeowners choose solar power systems. A reliable and efficient solar solution can power essential appliances like medical equipment, refrigerators, lights, etc.
- Off-Grid Living: Solar generators with high-capacity batteries can help you enjoy off-grid living. With a high-power solar generator, you can charge small and large appliances and keep them running for hours.
- Outdoor Activities: As solar generators are portable, they are a perfect charging companion for camping, hiking, RV trips, or outdoor activities.
- Sustainable Living: Homeowners wanting to choose a sustainable and eco-friendly power source can switch to solar generators. They can reduce electricity bills, lower reliance on fossil fuels, etc., by harnessing the sun’s power.
How Does A Solar Generator Work
A portable solar generator works when a solar panel converts sunlight into usable energy, which is electricity. Solar panels collect the sun’s energy during the daytime and transfer it to the battery storage system. Compact and transportable solar generators are convenient power solutions that charge appliances anywhere.
Here is the breakdown of the process:
- Solar panels convert sunlight into DC electricity which then passes through the charge controller.
- The charge controller regulates electricity voltage before storage, ensuring the proper current flow to the battery.
- The built-in battery stores all the power to charge the electrical devices later.
- The inverter converts DC to AC power to power most appliances and devices for hours.
The Types Of Solar Generators
Below are the three main types of solar generators.
On-Grid Solar Generator
This type of generator connects to the power grid to charge appliances. Solar panels capture sunlight to transform it into electricity in the form of DC. Then, the direct current is converted to AC in the power board. The board transfers electricity to power homes and buildings.
Also referred to as standalone or autonomous solar generators, they involve using batteries powered by solar panels. They are portable solar generators that can be carried during leisure travels, RV trips, etc.
Hybrid Solar Generator
This new-age solar generator is a combination of traditional generators with a controllable power source. The environment-friendly and fuel-efficient power supply source is preferred in areas where there is little access to petrol, LPG, or diesel.
