Solar Generator vs Gas Generator: Cost Comparison in 2026

On average, a typical residential solar generator setup costs around $17,000 to $24,000 before incentives. However, thanks to the federal 30% tax credit, the cost of the solar generator can drop significantly. Smaller portable solar generators for RVs and campers are available at much lower price points. Gas generators, on the other hand, can range from $500 to $3,000 for use in the home or an RV. However, with recurring fuel and maintenance costs, the overall price can add up quickly.

When the power goes out or when you are miles from the nearest outlet during an outdoor adventure, you need a reliable solar generator. Jackery Solar Generators have become a go-to solution for homeowners, campers, and travelers alike. These solutions are quiet, portable, and do not rely on fuel to keep you powered. This solar vs gas generator guide compares both generators in terms of upfront costs, operating expenses, and total savings over time.

AI Takeaway

• Solar generators may cost more upfront, but they have minimal operating costs, making them a more cost-effective long-term investment for homeowners and outdoor enthusiasts.
• Gas generators are cheaper to buy, but fuel and maintenance expenses add up quickly over time.
• With the 30% federal tax credit, switching to solar generators can reduce your investment cost by thousands.
• What are the long-term savings of owning a solar generator.
• How long do solar and gas generators last before needing replacement.

Which is Cheaper: Solar Generator vs Gas Generator?

Gas generators are cheaper upfront, but solar generators can save you more over time, especially if you're using them often. 

A basic gas generator for home or RV use typically costs between $500 and $3,000, depending on the brand and output.

On the other hand, a residential solar generator setup (such as a 7kW system) costs approximately $17,500 to $21,000 before incentives, but reduces after applying the 30% federal solar tax credit.

So, if you’re buying on a tight budget or need something just for the occasional outage, gas generators might seem more affordable at first. But when you factor in ongoing fuel expenses, noise, emissions, and maintenance, the numbers start to tilt in favor of solar, especially over several years of use.

What is the Cost of Running a Solar vs a Gas Generator?

Solar generators cost almost nothing to operate, while gas generators incur ongoing fuel and maintenance expenses.

Once your solar generator is set up, the produced energy is free. Sunlight does not cost a thing, and solar generators with built-in batteries can store energy for later use. There are no fuel bills, oil top-ups, or noisy engines to service. For RV owners and off-grid users, that means true independence without the constant worry of running out of gas.

Gas generators, by comparison, need fuel to operate every time. In 2025, natural gas delivered to power generators costs approximately $3.37 per million British thermal units (Btu), which is up 24% from 2024. For small backup units that run on gasoline or propane, prices can vary more depending on local fuel rates and usage frequency. You’ll also need to budget for engine oil, filters, and occasional repairs.

Over time, these operating costs accumulate. And if you're using a generator regularly, during long RV trips, or frequent outages, solar becomes the more cost-effective option.

What are the Long-Term Savings of Owning a Solar Generator?

Solar generators may cost more upfront, but they can save you thousands in fuel and maintenance costs over the years.

Let’s break it down with an example:

Say you invest in a solar generator that costs $20,000. With the 30% federal tax credit, you can lower the cost to $14,000. If you use the solar generator regularly for backup power, RV trips, or off-grid stays, you can save money. This is because sunlight is free, which means the running cost is basically zero with no fuel, oil, or heavy upkeep required.

Now let's compare that to a gas generator:

Even a small gas generator might use 1 gallon of gas per hour. If gas costs $4/gallon and you run the generator 5 hours a day, that calculates to around $20/day just in fuel. Using the gas generator for 200 days a year, you’re spending $4,000 a year on gas alone. The cost can quickly increase when you count on the oil changes and maintenance.

How Long Do Solar and Gas Generators Last Before Needing Replacement?

Solar generators can last 10 to 25 years, whereas gas generators typically require replacement within 5 to 10 years.

Most high-quality power stations, like those from Jackery, are built with LiFePO4 battery technology that can last over 10 years with proper use. The solar panels themselves often have a lifespan of more than 25 years. That makes solar generators a long-term solution for anyone looking to invest once and receive benefits for years.

Gas generators don’t last as long. On average, small portable gas generators can run for approximately 1,000 to 2,000 hours before requiring major repairs or a full replacement. If you use the gas generator for 5 hours a day, that gives you around 1 to 2 years of heavy use. Even with light use, most gas generators typically need replacement after 5-10 years, depending on the level of maintenance.
