Search terms like “solar generators for home use,” “best solar generators for camping,” and “solar power backup systems” have seen significant increases in volume. This surge in interest highlights a shift toward more eco-friendly and independent power solutions, making solar generators an attractive option for many people.
In this comprehensive guide, we’ll explore everything you need to know about solar generators, including how they work, what to look for when purchasing one, some of the top models available in 2024, and the various applications that make them shine.
What is a Solar Generator or Power Backup System?
What is a Backup Power System?
A backup power system has effectively two components: a battery, which stores electrical energy, and an inverter, which takes in power from a generator, solar panels, or your home grid, charges the battery, and outputs power, typically in both AC and DC, with different voltages, and through different outlet types. Often, this is going to be common outputs like standard 110V AC wall outlets, 240V for large appliances, 12V DC (like a car charger), and others. Higher capacity systems tend to have more options. A consumer grade backup power system will combine the inverter and battery into one device that provides both functions.
A backup power system may be paired with a generating system, such as a traditional gas generator or solar panels, or may simply be charged via plugging into the wall, something that obviously has its limitations if you’re concerned about the grid going down.
What is a Solar Generator?
A solar generator, very simply, is a backup power system (battery + inverter), paired with solar panels to charge. Pretty much all of the major backup power systems offer the ability to charge with solar, and almost all solar generator kits offer the ability to charge using methods other than strictly solar.

Types of Backup Power Systems: Which One is Right for You?
There are several types of solar generators, each designed to serve different purposes. Here's a breakdown of the most popular options:
1. Portable Solar Generators/Power Systems
These are compact, lightweight units designed for use on the go. These are ideal for outdoor activities like camping, hiking, and RV travel. Some of these are small enough to be easily thrown into a backpack, and are only ideal for charging phones, laptops, and other small electronics, while others are more suited to a trunk or truck bed, but can power a small refrigerator, TV, and other appliances for a weekend.

2. Home Backup Systems
Home backup systems are larger and more powerful units meant to provide backup power during power outages or for off-grid living. These systems typically offer a higher wattage, as well as more output types like 240V. They’re capable of powering essential appliances like refrigerators, lights, and medical devices, and are typically expandable, meaning you can add capacity with expansion batteries to make your backup last longer.
Home backups are the systems where it typically makes the most sense to pair with a gas generator, even in addition to solar panels, if maximum security is the goal.

3. DIY Solar Generators and Power Systems
For very technical DIYers, building your own custom system can be an option worth looking at. The advantage of this is the ability to fully customize the size of each component to exactly your needs, as you’re purchasing individual batteries, inverters, etc., and wiring everything together. A consumer-grade system requires no DIY, just plugging things into each other. There can also be cost savings with the DIY approach, however with some of the new consumer systems on the market, this has lessened quite a bit, and sometimes doesn’t exist at all.
The big downside to DIY is that there are very real risks to doing it wrong, as there are fire hazards as well as damage hazards (destroying your inverter by wiring incorrectly, for example). However, for someone who knows what they’re doing and has very specific needs, this can be a solid option.
Key Benefits of Solar Generators and Power Backups
1. Power Independence
Whether you’re taking a portable system into the back-country or adding a backup system to your home, these systems give you true power independence, allowing you to not be reliant on the grid while powering your key devices and systems.
2. Silent Operation
Unlike traditional gas generators, solar generators operate silently. This makes them ideal for camping, outdoor events, and power outages when noise could be a nuisance. You won’t disturb your surroundings, whether you’re at a campsite or during a late-night power outage.
3. Cost Savings
Although solar generators can have a higher upfront cost compared to conventional generators, they can provide long-term savings. Once installed, solar generators require little maintenance, and solar energy is free. This means no ongoing fuel costs or maintenance expenses, making solar generators a cost-effective investment in the long run.
4. Low Maintenance
Solar generators are generally low-maintenance. Unlike gas generators, which require fuel, oil changes, and regular servicing, solar generators only need basic upkeep. You’ll need to clean the solar panels occasionally and ensure the battery is functioning optimally, but overall, they require less attention.
What to Look for When Buying a Power Backup
Choosing the right solar generator involves considering several key factors:
1. Battery Capacity and Runtime
The battery capacity of a solar generator determines how much power it can store and how long it can run your devices. Higher-capacity batteries allow for longer use. Capacity is measured in Watt-hours (Wh), or kiloWatt-hours (kWh)(1kWh= 1000Wh). The calculation is simple, wattage times time, in hours. So if your system is powering 1 device that has a 100W power draw, a 1,000Wh battery could power it for 10 hours (100W x 10hr = 1000Wh). Make sure to select a generator that meets your needs based on your expected power usage.
2. Power Output (Wattage)
Wattage refers to how much power the generator can supply, or more simply, how much it can put out all at once. When calculating how much power you need, consider the wattage of the devices you plan to power. For example, a laptop might use about 50-100 watts, while a refrigerator could require 800-1200 watts.
For the example above, if your system had a 500W Output, it could power 5 devices at once that each have a power draw of 100W. One important thing to consider here is that many appliances have a different PEAK power draw than their RUNNING power draw. For example, an electric motor might have a peak draw of 200W when starting up, then settle into a steady average of 100W over the course of an hour. Most devices will list both, and you can always find out at least an expected average draw for a given device by searching the web.
3. Port Options
Different devices require different types of outlets. Look for a power system with a variety of the ports that you’ll use most, including AC outlets, USB ports, and 12V DC ports, to ensure you can power all your devices. Some important considerations here for a home system are whether or not you’ll need 240V output, a 50A plug for large appliances like a dryer or welder, or a 35A plug for something like an RV.
4. Recharge Time and Charging Options
The recharge time is crucial, especially if you rely on your solar generator for power in emergencies. Make sure your power system can recharge quickly via solar panels, wall outlets, your car, or a gas generator.
5. Weight and Portability
If you plan to use your power system for camping or travel, make sure it’s lightweight and easy to transport. Larger systems for home use tend to be heavier, but for portable models, look for a balance of power and weight.
6. Durability & Weather Resistance
If you’re using your solar generator outdoors, durability is key. Many models are built to withstand weather elements like rain, wind, and extreme temperatures, which is important for long-term use.
7. Warranty & Customer Support
Check the warranty offered by the manufacturer. A longer warranty period can provide peace of mind and protection against defects. Customer support is also important for troubleshooting and repairs.
