You pay a low-end cost of $17,538 for solar panels in 2022. The high-end cost is $23,458 in 2022. The average price of solar panel installation is $20,498 in 2022. Prices vary depending on a variety of factors such as system size, equipment options, and location.

Solar panel cost per watt

A solar panel cost per watt is the estimated total cost of a system, according to its size and type. The costs are divided into three categories: installation (system design + equipment), manufacturing, and installation.


Monocrystalline solar panels are made from whole silicon crystals, which allows for more efficient electricity generation. Monocrystalline panels typically have a black hue and come with a 25- to 35-year warranty. They’re also the most expensive option, but they offer the best performance.

Expect to pay around $1 to $1.50 per watt for monocrystalline solar panel systems with a life expectancy of 25 years or more. However, prices continue to drop as technology improves, so it’s important to do your research before making a purchase.


Polycrystalline solar panels are made up of multiple small crystals, as opposed to a single large crystal found in monocrystalline solar panels. This makes them less efficient but also more affordable. You can usually identify polycrystalline solar panels by their blue hue.

A typical polycrystalline panel costs around $0.90 to $1 per watt.

Thin Film

Thin-film solar panels can be made from an array of photovoltaic materials and layered with glass or plastic. They are less expensive than crystalline alternatives but are not as efficient. The cost per watt for solar panels varies depending on the size and type of solar panel. On average, thin-film solar panels cost between $1 and $1.50 per watt.

What impacts the cost of solar panels?

The cost of solar panels is impacted by a number of factors, these includes:

System size

The cost of a solar system is proportional to the size of the system. A larger solar system will have lower per-unit costs but higher overall costs.

This is because a larger solar panel system will require more materials, and will take longer to install. However, a larger solar panel system will produce more electricity, so you can save money in the long run by cutting your utility bills.


The location of your home will have a significant impact on the cost to install solar panels. The local climate and available sunshine hours are two key factors that will influence both the price of equipment and installation costs. For example, fewer sunshine hours will mean more expensive solar panels. If you live in a cloudy area with little to no sunshine, the installation costs may be as much as double that of someone living in a sunny area.

Solar panels and equipment

Solar panels and equipment costs will vary depending on the type of system, size, and location. The price also varies by whether or not you include installation costs in your calculations.

The cost of solar panels will vary a lot depending on the type and quality, where you buy them from, installation costs, and any rebates or tax incentives that might be available in your area.

Roof characteristics

There are a few factors that will impact the total cost of solar panels, such as roof slope, roof type, and location.

For example, a 30-degree sloping roof is easier to install than a 90-degree slope. Another consideration is the type of roofing material: asphalt shingles are less expensive than tiles or metal roofs.


Labor costs increase as a project becomes more complicated or difficult. For example, the labor costs for a typical solar panel installation are about $0.59 per watt of capacity. Installing battery backup adds another 15 percent to 30 percent to the project cost and labor time.

Permitting and interconnection

When installing a solar photovoltaic (PV) system, you may need to obtain permits and interconnect with the local utility. These can add significantly to the overall cost of your solar system.

The Department of Energy’s SolarApp+ is trying to reduce these costs. The app allows you to estimate the cost of permits and interconnection for your project. You can also find installers in your area who are familiar with SolarApp+.

Average solar panel installation cost by location

Cost to install solar panels on a roof

The average cost of installing solar panels is $16,620 for a 6 kW system. The cost can vary by the amount of sun you get in your area. Roof installations are the most common type of solar panel installation in the United States.

Ground-mounted solar panels cost

Ground installations are typically more expensive than roof-mounted solar panels. A 6 kW system will cost you between $18,000. The cost of a ground-mounted system depends on the size but is also affected by your location and whether or not you have a building to put it on.

Cost of solar panel mount system

Fixed solar panel mount

Many different types of mounting systems are available, depending on what type of roof the solar panels are mounted to. A fixed mount system is attached directly to the roof and is not adjustable. This option is less expensive, but it can be more difficult to install on a sloped roof. The average costs for this type of mounting system installation can range from $10 to $15.

Adjustable solar panel mount

When it comes to solar panel mounts, there are two main types: adjustable and non-adjustable. The adjustable mount allows you to change the angle of your solar panels throughout the year, while a non-adjustable mount is fixed in place.

The cost for this type of mount ranges from $200 -$500, but it can be more depending on the brand and type of mount you choose.

Tracking solar panel mount

This type of solar panel mount is designed for use on large properties, and it costs approximately $500-$1,000 to install.

How does a solar panel installation work?

A solar panel installation involves the installation of a system that uses photovoltaic cells to convert sunlight into electricity. The electricity is then directed towards an inverter and sent onto your home or business.

Choosing and ordering your equipment

The first step in a solar installation is to choose your solar panels and inverters. Homeowners have a lot of factors to consider when making this decision, such as durability, efficiency, and aesthetics.

Engineering site visit

When you’re ready for a solar installation, the first step is scheduling a site visit with one of our engineers. During this visit, they’ll take a look at your home and electrical panel to evaluate your property’s potential for solar. They’ll also assess how much power you can expect to produce with your new system.

The engineer will inspect roofs for structural integrity before installing solar panels, and make sure that electricity runs smoothly throughout the system once it is installed. They will also verify that your roof is suitable for solar panel installation.

Permits and documentation

Permits and inspections are required for a solar installation, and your solar installer will help you through that process. After the installation is complete, you’ll need to register your system with your utility company. Some states require this step, while others do not.

Solar installation

The installation process begins with the roof. The installer will take measurements and determine what kind of mountings need to be used.

After that, the electrical work begins, and this is usually where most of the time is spent on a solar installation. Wiring from the panels to your home’s breaker box will be installed, as well as any necessary safety features.

The last step is mounting the panels on your roof or in your yard. This usually takes one to three days, depending on the size of your installation.

Approval and interconnection

Before connecting a solar panel to the electric grid, officials will have to inspect your system. The representative will verify that all electrical wiring and mounting were done correctly, as well as use codes for roof setbacks.

The Department of Energy’s SolarApp+ is trying to make the interconnection process cheaper and quicker for everyone. Their goal is to reduce processing times from 60 days down to 10 days or less.

Tips for choosing a solar panel installer

When it comes time to install solar panels on your house, it’s important to choose a reputable company with a history of quality work. Ask the installer about their experience and number of installs. They should be licensed, bonded, and insured. A good company will offer a production guarantee (PG). Look for a minimum of three employees–this shows that the company is stable and here to stay.

Federal Solar Panel Tax Deductions

The government offers tax incentives to those who install solar panels on their house. The IRS allows you to deduct 26% of the cost of your system from your taxes. You can also deduct the cost of labor to install your system.

State solar panel rebates

States offer different incentives based on how much you invest in solar panels. Depending on the state, you may be able to save up to 50% with a federal tax credit and your own state’s incentives.

The ITC is very valuable when it comes to solar panel installation. The ITC also provides a tax deduction for homeowners who invest in solar panels. This incentive can save you thousands of dollars, so be sure to check what’s available in your state.


How can I take advantage of tax breaks and incentives?

You are eligible for a 26% federal investment tax credit if you put solar panels on your home. The credit is worth up to $2,000. To get the full tax credit you must have a solar electric system that includes solar panels or a solar water heating system.

How much does a 1 solar panel cost?

A single solar panel costs between $2.67 and $3.43 to buy and install. The price of the whole system is variable, with the capacity measured in watts. What size you need will be based on energy use and your roof’s sunlight exposure level.

Can solar panels really save you money?

Solar panels are an excellent way to save money on your electricity bill by helping reduce the amount of environmental damage that is caused by traditional energy sources. But even if you’re not convinced, solar panels are still an excellent investment because they can generate more money than the initial cost.

How many solar panels are needed to power a house?

The number of solar panels you need to power your house depends on how much energy your home uses. The average home in the U.S needs between 20 and 24 solar panels to cover its electric bills.

Do solar panels work at night?

No, solar panels do not work at night because they can’t generate enough power to run during the day.
