This technology is still in development and will likely become more efficient and streamlined as technology advances. A solar generator for the home will cost between $2,000 and $25,000, with most costing at least $10,000. The generator itself can’t do its job without the appropriate fuel, usually diesel, propane, or natural gas. Using diesel for a generator of the same size costs $175 per day on average.

Liquid propane generators cost $250 to $4,000 for portable models or $2,000 to $6,000 for permanent backup units, depending on size. Liquid propane lasts longer and burns cleaner than other fuels but is more expensive and requires a large storage tank, which increases installation costs. The Generac Guardian 3-Phase 20kW generator is one of the largest, most powerful air-cooled 3-phase generators on the market.

The Guardian 24kW is built to last for years with minimal maintenance. The warranty covers all costs (parts, labor and shipping) for the first two years, then major parts for the next three. Overall, this generator is ideal for short-term use in emergencies, off-grid camping or powering a mobile business. The average U.S. home needs a minimum of 5,000 to 7,500 watts to run a house, so common home generator power capacities begin at 10,000 watts and go up from there.
Permanently Installed
They will then need to mark each one with a label that shows how many watts the item uses. An installed generator hooks into a home’s electrical system, so a permit is required to ensure that the work is done correctly and safely. In addition, most municipalities will require a permit to pour a concrete pad to support the generator.
Ultimately, this legislation aims to improve grid reliability and lower prices for consumers by making more energy options available. It should be a key element of any permitting reform package that Congress moves forward with this year. GM launched GM Energy, its energy spinoff, in 2022 as a way to compete in the rapidly expanding home energy market. The new bundle, which includes the GM Energy Powershift Charger ($1,699) and GM Energy V2H Enablement Kit ($5,600) is approximately $7,299, the company says.
How Much Do Home Generators Cost and Are They Worth It?
You also want to work with approved or certified contractors so you stay under the warranty coverage. When a generator connects to all circuits in your home, it’s considered a whole house generator. Backup batteries are a relatively new alternative to home generators. Having power at home through an outage isn't just about convenience, although it certainly makes riding out a storm easier. "Outages lasting for days aren't just inconvenient. They can be life-threatening," Whaley explained.
Questions to Ask About Whole-House Generator Installation
Part of a whole-home generator installation is installing a permanent resting spot. The most common installation method is on a poured concrete pad, which offers reduced vibration and increased airflow and prevents pooling water from damaging or rusting the underside of the unit. Professional installation will run between $50 to $75 per square foot, including site preparation and concrete pouring. The idea is to use bidirectional charging equipment to push and pull energy from electric vehicles at any given time.
Home generators can be run by a variety of different fuel types, but all the ones on our list use either liquid propane (LP), natural gas (NG) or both. Those that can use both fuel types are easily converted, without tools, to be ready to burn whichever fuel is needed. Many generator manufacturers have online wattage calculators to help you determine what size generator is the best fit for your home. You can also calculate this number yourself by finding the wattage rating label on each of your essential appliances. Many appliances will be labeled with “starting watts” and “running watts.” The former is the power draw when the appliance first turns on, while the latter is the draw once it’s running. Most U.S. homes need at least 5,000 to 7,500 watts to cover minimum needs, so you’ll see standby generators offer nine to 20 kilowatts.

Natural gas, which is commonly used for whole home generators, tends to be the most affordable option, although it can also rack up costs, depending on how long you have to depend on it. "The largest expense by far is the cost of purchasing and installing the generator," according to Don Whaley, founder and former president of Direct Energy. Maintenance cost is one of several generator costs you'll need to account for.
If you decide to take the plunge for a whole-house generator, given your investment in installation, you’ll want a unit that performs well, which is where our ratings come in. Installation costs, including any needed concrete work, is part of the total cost. Installation included, a 9 kW Generac PWRcell system costs about $18,000. Removing Generac batteries, at $2,000 per 3 kWh battery, will lower the cost.
When in standby, you spend less than $5 per month on your generators. In the end, your total cost of repair and replacement is dependent on the size, type, and fuel used by your generator. Whole house, standalone units are usually more expensive to keep up than smaller ones. Only running essential circuits allow you to use a lower wattage generator. For example, an 18KW standby unit would work for a regular-sized home if you are only powering basic appliances.
Saving money on a generator purchase is primarily a matter of being patient, considering the timing, and knowing exactly what is needed. While simply finding one of the best cheap home generators is an option, homeowners don’t necessarily have to forgo desired features to stay within budget. The process of connecting new power plants to the national power grid – called interconnection – is complicated, expensive, and can take years to complete. If you’re looking for a generator that will power your whole home for multiple hours, we recommend at least 8,000 watts or higher.
