Generators can be fueled by natural gas, solar power or electricity. The main factor that will affect the cost of a generator is the power source. Keep in mind that when you purchase a generator you will not just be paying for the installation; you will also have to pay to power it.

Types of Generators

Natural Gas Generators: While natural gas prices go up and down through the years, it is a widely available resource not only in the United States but all around the world. On top of the fuel, generator prices range from $100 to $1000 and installation costs can put you back between $500 and $10,000 depending on the unit and the location.

Electric Generators: Battery-powered generators are readily available and have several advantages compared to gas generators. They power up quicker, run more quietly and don't give off harmful emissions. The downside, however, is that batteries can only run for a limited time and tend to have very low Kilowatt capabilities. Standard battery-powered generators typically only provide 1.5 to 3 Kilowatts and cost between $400 and $800. Installation costs for electric generators are usually minimal because these units are typically portable and do not require extensive installation.

Solar Power Generators: Solar generators are powered by the sun and have the ability to store power for when you need it. Solar powered home generators function just as well as gas and battery powered generators, and they are more environmentally friendly than other generators. The cost of a solar generator can range from as low as $100 to in the thousands, with the most popular choices ranging from $400 to $500. Installation prices on top of that can cost you close to $1000. The benefit of solar power is that the fuel source is free, and with many solar appliances, you can apply for a tax credit to help cover the costs of installation.
