Power outages can happen anytime—during storms, blackouts, or other emergencies. When the lights go out, it's important to keep your home running safely and smoothly. That’s where a whole house generator comes in. It provides backup electricity to your entire home, so you don’t have to worry about spoiled food, no internet, or being stuck in the dark. In this guide, we’ll explain the whole house generator cost, what affects the price, and how choosing the right one can save you money and give you peace of mind.

Types of Generators for Home Use
Choosing the right type of generator depends on your home’s power needs, budget, and how often you expect to lose electricity. Understanding these options can also help you better estimate the whole house generator cost installed, especially if you're planning to power your entire home. Below are the four main types of generators homeowners should know about:
1. Standby Generators
Standby generators are installed outside your home and are connected directly to your electrical system. They turn on automatically when the power goes out and can power the entire house. These generators are great for people who want a hassle-free and reliable backup, but they can be expensive to buy and install. They usually run on natural gas or propane.
2. Portable Generators
Portable generators are smaller and can be moved wherever you need power. They are a more affordable option and are usually powered by gasoline. You’ll need to start them manually and plug in the appliances you want to use. While they can’t power the whole house, they’re useful for running a fridge, lights, or phone chargers during an outage.
3. Inverter Generators
Inverter generators are a type of portable generator that is quieter and more fuel-efficient. They provide clean and stable electricity, which is safe for electronics like laptops and TVs. They are a good choice for small homes or short-term use during outages or even outdoor activities like camping.
4. Solar-Powered Generators
Solar-powered generators use energy from the sun, making them a clean and eco-friendly choice. They are quiet, easy to use, and don’t need fuel, which saves money in the long run. While they may not power a large home unless expanded with extra batteries and panels, they’re a great long-term investment for light to moderate energy needs.
Whole House Generator Cost: A Detailed Breakdown
Buying a whole house generator is a big decision, especially when you're thinking about how much it will cost. It’s not just the price of the generator—you’ll also need to consider the cost to install it, run it, and keep it in good shape over time. Understanding the total cost of whole house generator systems will help you plan your budget wisely and avoid surprise expenses down the line.
Generator Unit Price
This is the price of the generator itself—the machine that gives your home power when the electricity goes out. The price depends mostly on how much electricity it can provide.
-
Smaller generators that can power basic items (like lights, a fridge, and a few outlets) usually cost $3,000 to $6,000.
-
Larger generators that can power your entire home, including air conditioning and other large appliances, often cost $7,000 to $15,000 or more.
The price also changes based on the brand, fuel type (like gas or solar), and extra features (like smartphone monitoring). While traditional fuel-powered units may seem cheaper at first, solar-powered generators can save you more in the long run because they don’t need fuel.
Installation Costs
Installing a whole house generator is more than just plugging it in—it needs to be connected safely and correctly to your home’s electrical system. This part usually costs $3,000 to $5,000, depending on how complex the job is.
Here’s what’s included:
-
Labor: You’ll need a licensed electrician or technician to set it up properly.
-
Site Preparation: This might involve pouring a concrete slab, clearing space outside, or installing extra wiring.
-
Permits and Inspections: Many towns and cities require a permit before installation, and some require inspections to make sure it’s safe and up to code.
Tip: Some solar-powered or portable models are easier to install, which can help you save money on this step.
Operational & Maintenance Costs
Even after the generator is installed, there are ongoing whole house generator cost you’ll need to think about to keep it running properly.
-
Fuel: Gas, propane, or diesel-powered generators require fuel. Long outages can mean high fuel bills.
-
Maintenance: Like a car, generators need regular oil changes, filter replacements, and checkups.
-
Repairs: With long-term use, you may need to replace parts or make repairs, which adds to the overall cost.
One big advantage of solar-powered generators is that they have little to no fuel cost and require less maintenance, making them a more budget-friendly choice in the long run.

Key Factors That Influence Whole House Generator Cost
The whole house generator cost installed can vary widely depending on several important factors. Understanding these will help you choose the right system for your home—and your budget. Here are the key things that affect how much you’ll spend:
1. Home Size
The bigger your house, the more power it will need during an outage. A small home may only need a 7,000-watt generator, while a large home might require 20,000 watts or more to keep everything running. The higher the wattage, the more expensive the generator will be.
2. Energy Needs
Even two homes of the same size can have different power needs. If your home has central air conditioning, an electric stove, or medical equipment, you’ll need more power. Homes with lower energy use (such as LED lighting and energy-efficient appliances) can use smaller, more affordable generators.
3. Power Source
Generators run on different types of fuel: natural gas, propane, diesel, gasoline, or solar. The type you choose will affect both the upfront and long-term costs.
-
Natural gas is convenient if you already have a gas line.
-
Propane and diesel are reliable but may cost more in fuel over time.
-
Solar-powered generators are more expensive at first but can save you money in the long run since they don’t need fuel.
4. Transfer Switch Type
A transfer switch connects your generator to your home’s electrical system. There are two main types:
-
Manual transfer switches are less expensive but need to be turned on by hand.
-
Automatic transfer switches cost more, but they turn on your generator automatically when the power goes out.
5. Backup Duration
How long do you want your generator to run during an outage? If you only need it for a few hours, a smaller generator may be enough. But if you want to power your home for several days, you’ll need a larger, more fuel-efficient system or extra fuel storage.
Solar vs. Traditional Generators: A Cost Comparison
Choosing between a solar-powered generator and a traditional one (such as gas, propane, or diesel) depends on your budget, energy needs, and personal values—like being eco-friendly. Below is a comparison to help you decide which option might be better for your home.

While solar systems often have higher upfront costs, they can be more affordable in the long run due to no fuel and low maintenance. Traditional generators, though usually cheaper to buy, can end up costing more over time because of fuel and upkeep.
If you're weighing the cost of whole house generator systems, consider not just the initial price but how each type fits your lifestyle, energy needs, and long-term plans.
