Solar Generators VS Gasoline Generators- What’s the Ultimate Choice?

Generators are not some new technology. Some additions, like solar power, have given way to many new developments in the generator industry in recent years. Thus, many of us now have to choose between solar generators and gas generators when deciding on a unit.

Generators help to light up your home and maintain a normal lifestyle, even during power cuts. But when it comes to buying one, you may have a lot of confusion going in your mind. Well, no one can blame you when there are so many options. 

However, you don’t like to spend time in darkness either, do you? Let’s be honest here – we all love spending those “romantic” candlelit moments, but not for hours. Therefore, generators are essential, and you should buy one as soon as possible. 

This comparison of solar generators vs. gasoline generators will help you decide which one you should buy and for what purpose. In the end, you’ll also find a list of the best solar generators and best gasoline generators, specially handpicked by our team. But before we start, let’s give a basic introduction of both these types. 

Solar Generators – The Rising Star

We can’t deny that solar power is gaining popularity, with several advanced developments and increase in usage. Nowadays, people are even using solar electricity as their primary source of electrical energy. Solar generators use the same technology to store up the power and provide you with the same when required.

Solar Generators

Solar generators run on a battery or a battery pack that receives its power from the solar panel. The sunlight hits the solar panel and creates a collision of electrons and photos inside the solar cell. Direct current electricity is produced and sent through the battery and an inverter when converted to AC power.

Solar generators are loaded with benefits. These generators are basically small and compact and suitable for powering small appliances or charging electronics during a blackout. 

You can also use solar generators for camping since they have their sources everywhere. Most importantly, using these generators is extremely easy and safe. You cannot use a solar generator for charging larger home appliances or powering the whole house. 

Key Features
  • Lightweight, compact, and portable
  • Cheaper than gasoline generators
  • Can support small appliances
  • Ideal for camping and other such purposes
  • Safe to use

Gasoline Generators – The Conventional Beast

Gas generators are the conventional type of generators that run on gasoline fuel and resemble a combustion engine. The engine of this generator rotates a rotor inside the alternator. 

The motor is made from copper wire and spins next to two magnets. Thus, it generates electricity that you can use immediately. Unlike solar generators, gasoline generators do not require any external parts.

Inverter Generator fuel

These generators solely run on fuel – gasoline – and when the fuel ends, you have to refuel them. The most prominent feature of gas generators is that they can produce a considerable amount of energy right from the moment you put the fuel in. Using these generators, you can power multiple small and large appliances, as well as charge your electronic devices. 

Gas generators are available in many sizes. You can pick a small portable inverter generator or a large standby generator, as per your convenience. These generators are widely available in the market, owing to their popularity.

With all these benefits, they have some disadvantages too, which we will discuss later in this comparison. 

Key Features
  • Powerful output
  • Long run-time
  • Easy to use
  • Can support one or multiple small or large appliances
  • Suitable as a whole house generator

Features of Differentiation:

1. Size

Size is one real factor in charge while comparing solar generators and gas generators. So, how does size help? It greatly depends on your purpose. For example, if you are looking for something handy, say to carry for camping or for lighter use, a small and compact device has more utility than a large one.

solar generator size

Moreover, larger machines require more space. So, people with space problems may prefer a portable generator. Solar generators have a much smaller, compact, and lightweight design than gasoline generators. These generators have a light body, consisting mainly of a battery and an external solar panel. 

On the contrary, gasoline generators are larger because of added engine and framing, therefore taking up more space in your truck or garage. People who prefer space over power backup might not like these generators for this very reason. 

So, in the context of size, solar generators clearly win the fight.

2. Power

For most people, power is a more important feature than the size of a generator. After all, we buy generators for power backup during outages. So, which of these generators provides you with enough power? 

As a straight answer, we would say that gasoline generators provide more energy than solar generators. But, in this context, your definition of “enough” matters a lot. What are you planning to power using your generator?  This is the primary question you should ask yourself before buying any generator. 

Stealth Generator power

If you plan to power only some smaller appliances or charge some sensitive devices like smartphones or wearables, a standard solar generator would be sufficient. Or if you are planning to purchase something for camping needs, a solar generator’s performance would be satisfactory. 

But in case you have a greater power need, say you want to power your whole house or several multiple larger appliances (such as refrigerators, air conditioners, etc.), you would definitely require a gas generator

In short, gasoline generators do produce more energy and can provide better backup to your large appliances than solar generators. Therefore, in the context of power generation, gasoline generators are clearly the winner. 

3. Run Time

You never know when the electricity will be back. It can be minutes, hours, or even some days. Our life has become so dependent on electricity that living without it even for some minutes seems forever. Buying a generator has this exact reason behind it – that you have power even when your block is in darkness. 

Battery Generator Runtime

So, you would never want your generator to stop so soon. Therefore, run time plays a vital role in choosing a generator. Which of these generators provides you a longer run time? The run time of a generator depends on several factors, including the load, fuel capacity, etc.

In general, gasoline generators provide a more extended backup time since they have a larger capacity than solar generators. Solar generators store their power in a battery, from which you get to use it. Batteries have a lifecycle that’ll soon end. So, you would need to change them after some time.

Gas Generator Runtime

On the contrary, gasoline generators have a tank that requires refueling. So, not only do gasoline generators provide you a more extended backup, but also last longer than solar generators. It is a valuable feature if you live in an area where power outages are frequent, or generally for a longer time. 

4. Safety

Safety is another big concern with generators. According to a report from The United States Consumer Product Safety Commission or CPSC, there were 665 reported accidents related to generators occured between 2015 to 2017, killing 880 people. In 2017 alone, sixty-nine deaths were reported in these 54 fatal CO incidents.

So, while purchasing a generator, one should be all the more concerned about generator-related accidents and fatality. However, with technological developments taking place, the frequency of these accidents has decreased. But, as they say, prevention is better than cure.

In terms of safety, we can reliably say that solar generators are much safer than gasoline generators. The former do not emit CO or carbon monoxide – a tasteless, colorless, odorless harmful gas. Solar generators, thus, create no emissions. You can use these indoors, in tents, or even in your vehicle without any worries.

On the contrary, gasoline engines produce exhaust gases, which are dangerous and can prove fatal, at times. Therefore, you have to use these generators outdoors in a well-vented area. Make sure you keep your gasoline generator’s exhaust point away from your home.

That said, in terms of safety, solar generators are a much safer and smarter choice and a clear winner of the competition. 

5. Noise

The last thing anyone would ever want during power outages is noise. Well, we understand that you could have power in your home, but that doesn’t mean your neighbor would, too. However, we can assure you that even you wouldn’t prefer a noisy generator under any circumstances.

Considering that, manufacturers are now focusing on developing quiet generators that would not produce much disturbing noise. Neither solar nor gasoline generators cause any disturbance in terms of noise. However, if you prefer a clear distinction, we would say that solar generators are quieter than their competitors. 

Solar generators use a battery to provide power backup. Unlike gas generators, they don’t have a rotator inside the alternator that the engine rotates. So, they don’t create much noise and offer an almost silent performance.

On the contrary, gasoline generators have a huge tank and massive engine that creates noise. Although low, they are considered noisy as compared to solar generators. Therefore, if you want some exact answer, we would say that solar generators are much quieter than gasoline generators. 

6. Price

While talking about the price, we would compare solar generators vs. gasoline generators in two sections – the upfront cost and the recurring cost. The upfront cost is the machine’s purchase cost, whereas the recurring costs are the costs you’ll pay over time. 

While solar panels are costlier and increase a solar generator’s price, the recurring cost for them is much lower than gasoline generators. It is primarily because the fuel source of solar generators is infinite. So, you don’t have to refuel the machine when it’s out of charge.

On the contrary, gasoline generators run on gas. So, when the fuel finishes, you have to refuel the machine. The price of gasoline would effectively cost you more in the long run. Hence, although the upfront costs might be low, the price you’ll have to pay overtime is considerably higher than solar generators.
