Fuel Generator Vs. Solar Generator For Home

Solar Generator

Who doesn’t want to save money? And what better way to do it than by generating your own power? There are several ways to generate power and save money on your energy bill, from fuel to solar generators.

But which is better, a fuel generator or a solar generator? Let’s examine each option to determine which is the better choice for your home.

How Does A Solar Generator Work?

A solar generator is a device that converts sunlight into electrical energy. It can power various devices, from small electronics to entire homes. Solar generators use photovoltaic cells, also known as solar panels, to convert the Sun’s rays into electrical current. The electricity produced by the solar panels is then stored in batteries for later use.

PV cells are made of semiconductor materials, like silicon. When the Sun’s rays hit them, they loosen electrons from the atoms, a process known as the photovoltaic effect. The freed electrons then flow through the material to create an electric current.

This is stored in batteries until needed and then inverted to power your home.

Solar Panels

Solar Panels

The average solar panel produces about 1 kilowatt of power, but the output can vary greatly depending on the weather and time of day. A solar panel will produce more power when placed in direct sunlight and less power in shade or cloudy conditions.

Solar panels comprise many individual solar cells that convert sunlight into electricity. The more cells in a solar panel, the more power it can produce.

Solar panels are most commonly used to generate electricity for homes and businesses but can heat water, air, or power appliances.


An inverter is a device that converts direct current (DC) into alternating current (AC). Solar panels produce DC electricity, but most appliances and devices use AC. So, the inverter is necessary to power your home with solar energy.

Charge Controller (BMS)

Charge Controller (BMS)

A charge controller (BMS) regulates the flow of electricity from the solar panels to the batteries, preventing them from being overcharged and damaged.


The most important part of a solar generator is the battery. This is where the electricity produced by the solar panels is stored so it can be used when there is no sunlight.

Solar batteries are typically lead-acid batteries, but newer types, like lithium-ion batteries, are also used in solar generators. All the electricity produced by the solar panels flows into the batteries, and then the inverter converts it to AC power that can be used to power your home.

Types Of Solar Generators

There are two main types of solar generators: portable and stationary.

Portable Solar Generators

Portable Solar Generators

Portable solar generators are small, self-contained units that can be easily transported and used to power various devices, from laptops to camping gear. They typically have a built-in inverter and can be recharged by plugging them into an outlet or using solar panels.

Portable solar generators are an excellent option for people who need to power small devices while away from home or for those who want a backup power source in an emergency.

Stationary Solar Generators


Stationary Solar Generator

Stationary solar generators are larger units designed to be permanently installed at a home or business. They typically have a higher output than portable solar generators and can power larger appliances like refrigerators and air conditioners.

Stationary solar generators usually require professional installation, but they can provide a reliable backup power source for homes and businesses.

How Does A Power Generator Work?

Fuel Generator

A fuel generator is a device that converts chemical energy from a dual fuel source into electrical energy. The most common type of power generator uses gasoline, diesel, or propane as its fuel source. Gas generators use an internal combustion engine to convert the fuel’s chemical energy into mechanical energy, which is then used to generate electricity.

The internal combustion engine ignites the fuel in a chamber, creating a high-pressure blast of hot gases. These hot gases push against the piston, which turns a crankshaft. The crankshaft is connected to an alternator, which produces electricity. This electricity is then sent to a rectifier, which converts it into AC power that can be used to power your home.


The engine is the heart of the power generator. It converts the fuel’s chemical energy into mechanical energy. The most common power generator engine type is a four-stroke gasoline engine. The power output will vary depending on the size of the engine, but most power generators have an output of around 5,000 watts.


The alternator produces electricity. It is a device that converts mechanical energy into electrical energy. As the engine runs, it spins the alternator, producing an electric current. This electric current is sent to a storage battery, where it can be used to power electrical devices.

Battery Charger

The battery charger is a device that charges the storage battery. It takes the electrical energy produced by the alternator and uses it to charge the battery. The battery charger is an integral part of the power generator because it ensures that the storage battery is always packed and ready to use.

Voltage Regulator

The voltage regulator is a device that controls the flow of electricity from the alternator to the storage battery. It prevents the battery from being overcharged and damaged.

Fuel System

The fuel system supplies fuel to the engine. It typically consists of a fuel tank, a fuel pump, and a filter. The tank stores fuel until it is needed.

The pump moves fuel from the tank to the engine, and the fuel filter removes impurities before it reaches the engine.

Cooling And Exhaust System

The cooling and exhaust system keeps the engine cool and removes the exhaust fumes from the generator. The cooling system consists of a radiator and a fan. The radiator dissipates the heat from the engine, and the fan helps to circulate air around the engine.

The exhaust system removes the fumes produced by the engine. It typically consists of a muffler and a tailpipe.

Control Panel

The control panel is where the operator controls the generator. It typically has switches for starting and stopping the generator and controlling the voltage and frequency output. The control panel may also have gauges that indicate the generator’s status, such as the oil pressure, coolant temperature, and fuel level.

Lubrication System

The lubrication system keeps the engine parts moving smoothly and prevents them from overheating. It consists of an oil pump, filter, and oil pan. The oil pump moves the oil from the oil pan to the engine.

The filter removes any impurities from the oil before they reach the engine. The oil pan holds the oil that is not used by the engine.

Types Of Power Generators

There are four main types of power generators: portable, standby, inverter, and induction.

Portable Power Generators

Portable Fuel Generators

Portable power generators are small and lightweight, making them easy to transport. They typically have a power output of around 2,000 watts and are ideal for camping, tailgating, and other outdoor activities.

Standby Power Generators


Standby Fuel Generator

Standby power generators are more significant than portable generators and are typically installed permanently at a home or business. They typically have a power output of around 10,000 watts and provide backup power in case of a power outage.

Inverter Power Generators

Inverter Fuel Generators

Inverter power generators are designed to produce clean, stable power. They typically have a power output of around 2,000 watts, making them ideal for powering sensitive electronics like computers and TVs.

Induction Power Generators

Induction Fuel Generators

Induction power generators are the most efficient type of generator. They typically have a power output of around 10,000 watts and are used in industrial applications.

So, there you have it! A comparison of solar and power generators. As you can see, each has its advantages and disadvantages. But depending on your needs, one may be a better choice than the other.

Scenario 1: Backup Power

A backup generator is necessary if you live in an area with power outages or severe weather conditions. But which type of generator is the best for emergencies?

A power generator is a good choice for emergency power because it can run for long periods without refueling. However, power generators can be dangerous because they emit carbon monoxide gas, which can be deadly if it builds up in a confined space.

Solar generators are safer for emergency power because they don’t produce harmful gases. They’re also much quieter than power generators, so you won’t have to worry about disturbing your neighbors when the power goes out.

The downside of solar generators is that they require sunlight to work at a high capacity. The generator will not produce as much power if the Sun is not shining. This means that a solar generator may not be able to provide enough power for your entire home during a long-term power outage.

Scenario 2: Off-Grid Living

A solar generator is your best bet if you want to disconnect from the grid completely. If you have enough sunlight, solar generators can provide all the power you need. You can use power generators for off-grid living, but you’ll need a reliable fuel source. This can be a problem if you’re living in a remote area, as it may be challenging to find and transport fuel.

With solar power, you can say goodbye to noisy generators and the hassle of finding and storing fuel, but you may need to invest in a backup power source for cloudy days.

Scenario 3: Recreational Use

If you’re using a generator for recreational purposes, like camping or tailgating, then either generator will work. However, solar generators have the advantage of being quieter and more environmentally friendly. Power generators are typically cheaper and easier to find but can be noisy and produce harmful emissions.

Scenario 4: Emergency Use

In an emergency, you’ll want a generator to provide as much power as possible. In this case, a gas-powered generator is your best bet. You can use solar generators in an emergency, but they may not provide enough power to run your virtual devices.

Here it depends on how much power you need. A solar generator could work if you need to run a few lights and a small fridge. But if you need to power a large home or run multiple devices, you’ll need a gas generator.

What Size Generator Do I Need?

The generator size you need depends on the wattage of the devices you want to power and the peak amperage the generator can handle.

For gas generators, look at the Wattage (W) rating. This is usually given in Kilowatts (kW), so you may see kW instead of W. This measures how much power the generator can produce.

For solar generators, look at the peak amperage rating. This is the maximum amount of current that the generator can handle.

To determine the size of the generator you need, you’ll need to know the wattage of the devices you want to power and the generator’s peak amperage rating.

The amp rating is the maximum amount of current that a generator can handle. It is important because it determines how many devices can be run simultaneously.

For example, if you have a solar generator with a peak amperage of 10 amps, you could theoretically run ten 100-watt lights simultaneously. But the generator will overload and shut down if you try to run more than ten amps worth of devices.

Massive Fuel Generator

So, how do you determine the wattage of your devices?

The wattage of a device is usually listed on the device itself. If it’s not, you can use this formula:

Wattage = Volts x Amps

For example, if a light uses 120 volts and draws 0.5 amps, the wattage would be 120 x 0.5 or 60 watts.

You can use this formula to calculate the wattage of any device. Remember that the wattage will differ if the device runs at full or half power.

For example, a 100-watt light running at half power will only use 50 watts.

Now that you know how to determine your devices’ wattage and the generator’s peak amperage rating, you can choose the right size generator for your needs.
