In this blog post, we’re going to explore and compare solar generators and gas generators as backup power options. As extreme weather events increase and our aging power grid continues to fail, having reliable backup power has become essential. Knowing which type of generator is right for you is critical. In this guide, we’ll cover the pros and cons of both systems, how to use them during a power outage, and discuss what the ideal backup system might look like.
Why Backup Power Is Essential
The modern world depends heavily on electricity, whether it’s for communication, work, or keeping essential appliances running. But with the increasing number of power outages due to storms, wildfires, and aging infrastructure, many people are looking for ways to ensure they have power when the grid goes down.
Topics We’ll Cover:
- The pros and cons of gas generators vs. solar generators.
- How to use these systems when the power grid fails.
- What the ideal backup power system looks like.
- Final thoughts on choosing the best option for your needs.
Let’s jump in!
The Pros and Cons of Gas Generators
Gas generators, also known as internal combustion engine (ICE) generators, are the traditional option most people are familiar with. These generators run on gasoline, propane, or diesel.
Pros of Gas Generators
- On-Demand Power: Gas generators can provide immediate power as long as you have fuel available. Whether it’s propane, gasoline, or diesel, the generator is ready to go when you need it.
- Lower Upfront Cost: Compared to solar generators, gas generators typically have a lower purchase price. For those on a tight budget, this can be a big advantage.
- Fuel Flexibility: Some models, such as dual fuel or tri-fuel generators, can run on different types of fuel. This versatility can be useful, especially if one fuel source is more readily available during emergencies.
Cons of Gas Generators
- Noise: One of the major downsides of gas generators is the noise they produce. Running one can draw attention, especially in a post-disaster situation when you may prefer to stay unnoticed.
- Fumes: Gas generators produce harmful fumes, including carbon monoxide, which can be dangerous if the generator is not properly ventilated. This makes them unsuitable for indoor use.
- Fuel Dependency: You are limited by the amount of fuel you have on hand. After a disaster, fuel shortages can occur, and long lines at gas stations are common.
- Maintenance: Gas generators require regular maintenance, such as oil changes, filter replacements, and tune-ups. If the generator breaks down and you don’t know how to repair it, it could leave you without power when you need it most.
- Mobility: Larger gas generators can be bulky and difficult to transport, especially if you have a limited vehicle space.
The Pros and Cons of Solar Generators
Solar generators are becoming increasingly popular due to advancements in solar technology. These systems use solar panels to harness the sun’s energy and store it in batteries for later use.
Pros of Solar Generators
- Unlimited Power from the Sun: As long as the sun is shining, solar generators provide a virtually endless power supply. There’s no need to worry about fuel shortages or standing in line for gas after a disaster.
- Silent Operation: Solar generators make no noise, which is perfect for those who want to maintain operational security (opsec). Neighbors won’t know you have a power source, and it won’t attract attention.
- No Fumes: Since solar generators don’t burn fuel, they produce no fumes. You can safely run them indoors, unlike gas generators.
- Low Maintenance: Solar generators require minimal maintenance. Aside from ensuring the battery is charged and the system remains clean, there is little else to worry about.
- Portability: Solar generators are often more portable than gas generators. Solar panels, especially foldable or solar blankets, are easy to transport and set up.
Cons of Solar Generators
- Higher Upfront Cost: Solar generators typically cost more upfront compared to gas generators. However, the price of solar technology is decreasing, making these systems more affordable over time.
- Dependence on Sunlight: If it’s cloudy or nighttime, solar generators won’t charge effectively unless you have a backup power source. Solar panels often operate at 70% efficiency, and this can drop further in poor conditions.
- Slow Charging: Even with ample sunlight, solar generators take time to charge. If you need large amounts of power quickly, gas generators may be more suitable.

Choosing the Best Backup Power System
The best backup power system depends on your specific needs, location, and budget. Here are some scenarios to help you decide:
Gas Generators Are Best If:
- You live in an area where sunlight is unreliable, and you need immediate, on-demand power.
- You have access to fuel, and noise or fumes aren’t an issue for your situation.
- You’re looking for a lower upfront cost and are comfortable performing basic maintenance on your generator.
Solar Generators Are Best If:
- You want a silent and fume-free option that can be safely used indoors.
- You live in a sunny area where solar energy is abundant.
- You prefer a low-maintenance solution and don’t want to rely on external fuel sources.
- Portability and ease of transportation are important, especially for camping or off-grid use.
What Does the Ideal Backup Power System Look Like?
For many, the ideal backup system could be a hybrid solution. Combining both solar and gas generators ensures you have access to power in any situation. During sunny days, your solar generator can power essential devices and charge up. When the sun isn’t an option, you can switch to your gas generator for on-demand power.
Key Considerations for a Hybrid System:
- Fuel Storage: Store extra propane or gasoline to keep your gas generator running for extended periods.
- Solar Panels: Invest in high-efficiency solar panels to maximize energy production during daylight hours.
- Battery Capacity: Choose a solar generator with a large battery capacity to store energy for nighttime use.
Final Thoughts: Solar Generator vs Gas Generator
Both solar and gas generators have their place in a comprehensive backup power plan. Gas generators provide on-demand power and are generally more affordable upfront, but they come with noise, fumes, and fuel dependency. Solar generators are cleaner, quieter, and offer a renewable energy source, but they rely on sunlight and can be more expensive.
In conclusion, if you’re looking for instant power during emergencies, a gas generator may be the better choice. However, if you’re focused on long-term sustainability, portability, and quiet operation, a solar generator might be the perfect fit. Consider your unique needs, and you’ll be better prepared for any power outage.
