Cost of Solar Panels For House Roof: Residential Solar Panel Installation | Solar Panels Cost

Cost of solar panels for house roof

Are you running out of power sources for your home? Do you wish that there was a more sustainable, cost-effective option than relying on the grid? Well, now there is! Solar panels are quickly becoming more and more affordable as they become less expensive to produce.

The cost of solar panels will vary depending on a number of factors, including the size and type. The average cost for installing rooftop solar panels is approximately $20,498.

The solar panel industry has recently seen an increase in both production and demand. This means that prices have dropped dramatically over the past few years. Solar panels can be installed on any roof type and size, from small residential roofs to commercial rooftops with plenty of room for installation. With these new savings, solar panels for the average home are becoming more and more affordable.

Average costs of solar PV panels for residential roof

The average cost of solar panels for the house roof is $2.77 per watt. The average size of the home’s roof is 2,660 square feet or 240 square meters, which results in an approximate total system size of 470 kilowatts (kW), not including any other installations such as wiring or energy storage components.

Average costs per watt are currently on the decline, so it’s possible that you may even see this price drop in the coming years.

The price per watt does not paint the whole picture when it comes to solar panel costs. There are a number of different installation companies that charge different rates, and you’ll need to consider other equipment such as inverters and batteries that will affect the final price before signing up with any contractor. In general, prices tend to drop as more people buy solar panels because the supplier is able to produce them at a lower cost. This helps make solar energy more affordable for everyone!

Residential solar panel system costs

Residential solar cost varies depending on many factors such as size, equipment, and location.

System size

System size is one of the main factors in determining the cost to install solar panels on a home. A 2 kW system may cost $5,540 while a 10 kW system can be much more expensive and may cost $20,498.

System size is an important factor for homeowners to consider when thinking about installing solar panels because typically, the larger a solar panel system is, the more expensive it will be. A small 2 kW system might produce enough energy to run half of a home while a 10 kW system can generate 5-7 times the amount of energy needed by some families. In this way, a larger solar panel system will pay for itself much faster depending on the amount of energy needed by a home.

It should be noted that going bigger is not always better and this should be taken into consideration when looking to install a solar panel system. Even though a 10 kW system may produce enough energy to run 4-5 homes, it is still expensive and may cost more than necessary for some homeowners.


Solar panels are also very dependent on technological advances which means that newer equipment will typically cost more than older equipment. For example, in the past 5 years, solar panel costs have dropped by 50%, while the efficiency of panels has increased up to 20%. This means that newer technology will cost more than older technology.

Equipment costs can be reduced by purchasing used or refurbished equipment, but this should only make up a small percentage of the overall cost to install solar panels for a home.


The location of installation is also an important factor in determining price because different areas receive different amounts of sunlight which affects how much energy a system can produce. The amount of sun that hits the panels will determine their output which will affect how much money is saved on electricity bills each month. A solar panel system located in Los Angeles will produce much more electricity than one installed somewhere like Alaska.

The amount of sunlight that hits a solar panel also determines how fast it will pay itself off. A solar panel system located in Los Angeles may generate $50,000 worth of electricity over its lifetime whereas one installed in Alaska may only produce $10,000 worth of electricity. This is why installation location matters to homeowners who want to save money on their energy bills by installing solar panels for their homes.

Roof characteristics

The shape of a home’s roof is also important because different roofs have different degrees of incline that can affect the performance of solar panels. A small residential roof may not be able to hold as many panels like a large commercial roof which means more equipment will need to be purchased to fit on the smaller area.

The roof itself does not matter, only the amount of sunlight that is able to hit the solar panel. Solar panels are designed for maximum efficiency when placed in areas with an average of five hours of direct sunlight per day. They may not be as effective on a roof that is mostly shaded by buildings or trees.

Permitting and interconnection

In some areas, the installation of solar panels may require a permit from local authorities. In other cases, there are no permits required which means that homeowners can simply install the solar panel system themselves.

Permits do not typically affect the overall cost to install solar panels on a home but it will take longer before they are connected to the electrical grid and begin producing energy.

The interconnection process is also important because it allows the solar panel system to connect with the power grid. Most installations are fast and easy, taking about 24 hours for most setups, but there are situations where it takes longer to complete. For example, if a local utility company needs to increase capacity in order to supply energy from the solar panels, installation may take up to three weeks.

Types of solar PV panels

cost of solar panels for house roof

There are three main types of solar panels: monocrystalline, polycrystalline, and thin-film.


Monocrystalline panels are the most efficient because they are made from a single silicon crystal. This means that less space is needed to generate the same amount of power as other panel types. Also, monocrystalline panels last longer and produce the best results in areas with very hot climates because they do not warp or melt like other types of solar panels.


Polycrystalline panels are made from multiple silicon crystals which makes them less efficient but also less expensive.

Polycrystalline panels are a good option for homeowners who want to save money on their solar panel systems. They are less efficient than monocrystalline panels but they are also less expensive. This makes polycrystalline panels a good option for homeowners who want to invest in a solar energy system without spending too much money.

Polycrystalline panels are also a good option for homeowners who live in areas with less sunshine. These panels perform better in areas with less direct sunlight than monocrystalline or thin-film solar panels.

Thin Film

Thin-film panels are the least efficient but also the least expensive. They are made from a thin layer of silicon that is applied to a substrate like metal or glass. The advantage of thin-film panels is that they are flexible and extremely durable. The downside is that they convert sunlight into energy less efficiently than other types of solar panels.

Solar PV system components

There are three main components in a typical residential system: a photovoltaic module, an inverter, and a racking system.

Photovoltaic Module

The photovoltaic module is the actual solar panel itself which converts sunlight into electricity. These can be installed on existing roofs or made part of new rooftop construction when building a home from scratch. Some homeowners decide to add an extra room or second story so they can have more space for solar panels on their roofs.


Inverter changes direct current (DC) electricity produced by solar panels into usable alternating current (AC) power. This lets the house operate on regular household appliances instead of only running smaller items like lights and outlets.

Racking System

The racking system is installed on top of the roof to support the weight of solar panel modules, batteries, and other equipment that are part of a complete energy system. The racking system also transfers electricity from the solar panel module into an inverter for storage in batteries or connection with the power grid.

When planning out their home energy systems, homeowners should consider all costs associated with the installation including permitting fees, interconnections fees for connecting with the electrical grid, inspection fees after installation is completed, and wiring expenses which includes any necessary electrical upgrades needed in order to handle the solar panels. When considering costs, homeowners should also think about ongoing expenses such as maintenance and repairs, battery replacement for systems with storage capabilities, and inverter replacement which is typically expected after 10-15 years.

Average Solar Installation Cost by Location

Solar panels may be built on the ground as well, although this is not their primary location of installation. They can also be erected utilizing a frame positioned on the ground. This is an excellent alternative if your roof isn’t able to support the panels or is mostly in the shade. Both installation methods have a number of concerns to consider, including costs of installation.

Cost to Install Solar Panels on a Roof

The average solar panel costs are between $15,000 and $21,000 for a 6 kW system. The most popular are roof installations. They take up less room and are less expensive to purchase and install. They’re difficult to access and maintain, but they don’t take up much space. If you need to replace your roof, you’ll have to reinstall the panels. They’re also tough to expand as they grow, thus if you need more panels, you may run out of room.

Putting solar panels on the roof not only increases the value of your home but also increases energy efficiency. It reduces monthly electric bills thanks to increased self-production and cuts energy costs that would’ve been spent on electricity from a utility company.

Ground-Mounted Solar Panels Cost

Ground-mounted solar panels range in price from $18,000 to $25,000 for a 6 kW system. In most cases, ground installations are not used in grid-tied situations. Because they take up more room, you’ll need a lot of space in your yard. They’re also more expensive to buy and install. However, because they are not as hot, they are simpler to maintain and more efficient. It’s also simple to expand your system if you have the room.

The ease of installation and no need for permits make solar panels rooftop installation the most popular choice. It’s also less expensive than ground installations and requires little space.

Whether installing on your roof or on the ground, homeowners should consider all factors before deciding to go solar. This will ensure you get the most benefits from your investment. As with any major decision involving a lot of money, it’s best to do some research first as well as talk to more experienced people that have already gone through the process before making a final decision.

Solar Panel Installation Costs by Type of Mounting System

When considering solar panel installation cost, one of the first decisions you’ll have to make is what type of mounting system to use. There are three main types: fixed solar roof mount, ballast solar mount, and pole solar mount. Each has its own set of pros and cons, so it’s important to understand the differences before making a decision. The photovoltaic panel installation cost for each type of mounting system varies, but on average you can expect to pay between $5-$7 per watt for a fixed mount, $3-$4 per watt for ballast/pole mounts.

Fixed Solar Mount

This is the simplest type of solar installation possible, and also the most affordable. A fixed solar mount affixes your panels to your roof with screws or clamps that either bolt into existing roofing materials or come with their own adhesive backing. The panels lock into the solar mount and simply sit on top of your roof.

Ballast Solar Mount

For those who would like a little more security for their solar panel installation, ballast mounts provide that extra peace of mind. Also known as “pitch compensation” mounts, they support the back end of your panels with some type of weight (either bricks or concrete blocks) which absorb shock and keep the roof from sagging under the weight of the panels. This is important if you live in an area where there are strong winds or lots of snowfall; both can make a fixed mount system less effective at keeping your panels protected from high winds and winter conditions.

Pole Solar Mounts

Pole mount systems are similar to ballast mounts in that they use weights to keep the back end of your solar panels stable. The primary difference here is that instead of attaching the weight directly to your roof, pole mounts attach it to a mounting pole or post that’s placed on top of or beside your roof. This takes some of the weight stress off your roof and redistributes it for better stability. However, pole mounts can be somewhat unsightly if you have an eye for aesthetics.

Tracking Solar Panel Mounts

This type of solar panel installation is for those who want to get the most out of their system by maximizing exposure to sunlight. Tracking mounts include a single axis tracker, an adjustable-angle mount that rotates your panels automatically (usually at a rate of 1 degree per second) throughout the day to match the movement of the sun and capture more energy. Such systems typically cost $800-$1,000 more than fixed multi-crystalline solar panel installations.

Solar panel price by manufacturer

Solar panel prices vary by manufacturer. Some of the more well-known and established brands can be a bit more expensive, but you can also find some great deals on less well-known brands. It’s important to do your research and compare prices before making a decision.

In addition to solar panel cost, you’ll also want to consider factors such as quality, warranty, and customer service. Make sure to ask the installer questions about these things so you can make an informed decision.

Solar panel price by state

Solar panels cost also vary by state. Some states have more incentives for solar panel installation than others, so the cost will be lower in those states. In addition, some states have more sun than others, so the panels will be able to generate more energy in those states.

It’s important to do your research and find the best deal possible. Talk to several installers and get quotes before making a decision. Then choose the one that’s right for you. Installation costs and the cost of inverters and other equipment can vary, depending on what you’re looking for and where you go.

Solar panel cost calculator

A solar energy calculator can help you find out how much a solar panel system will cost and how much money it will save you over time. Use the calculator to see if going solar is a good idea for your home or place of business. You’ll be surprised by just how affordable a solar system can be!

The best way to learn about solar panels costs is to talk with an installer in your area. They’re experienced with all types of roofs and they know exactly what each roof needs in order to support a powerful, effective solar panel system. When you have questions about installation or maintenance, they’ll be able to answer quickly and easily so you’ll always know your solar energy system is working as it should.

How do you pay for installing solar panels?

Once you’ve determined the cost of solar panels for your particular project, it’s time to figure out how you’ll finance it. A cash purchase, a solar loan, or a solar lease/power purchase agreement are the three most common ways to fund solar panel installation costs.

Cash purchase

If you have the cash available, a cash purchase means that you can install solar panels with no strings attached. You’ll own the system outright after you pay for it, so your monthly energy savings will be higher right from day one. However, if something goes wrong with the system down the road it’s up to you to fix or replace it.

Solar loan

A solar loan uses money from a lender to pay for your solar installation. Loans usually carry a lower interest rate than other kinds of loans because they’re “secured” by your home’s equity.

In addition to the interest rate, there are also fees associated with taking out a solar loan. The total cost is higher if you do not have equity in your home and need to pay closing costs on the loan itself. Solar loans tend to be more expensive when they cover a large percentage of the project cost or have relatively shorter repayment terms (e.g., less than 10 years). Longer repayment terms normally result in either lower monthly payments or a more favorable interest rate.

Solar leases and power purchase agreements (PPAs)

If you don’t have the cash, but your home has equity, both solar leasing and PPA’s can allow homeowners to pay little to nothing upfront for the installation of solar panels on their roofs. When you sign up with an installer that offers one of these arrangements, they’ll install the solar system at no cost to you and sell all of the power generated by your rooftop array back to your utility company. The monthly payment is substantially less than what you would pay if you bought power from your utility company rather than through one of these arrangements. However, unlike loans, customers are not able to take advantage of tax incentives or other homeowner benefits.

Solar leases and power purchase agreements are both 20-year contracts, but there are several key differences between the two:

A solar lease requires less paperwork than a PPA because the installer owns the system, not you. It’s important to note that with both options, there is no threat of home damage or fire risk associated with rooftop solar panels. Thus, your homeowner insurance rate will likely not be affected by installing solar panels on your roof. Additionally, most people who lease their rooftops for solar do not have to deal with any roof repairs as long as they remain in good standing with their installer—usually for 8-10 years or longer.

A PPA is like making monthly rental payments for your solar system, but with none of the benefits of ownership. Customers are also responsible for what happens on their roof even if the panels are installed by an installer.

Solar leases and power purchase agreements can offer excellent savings on your electric bills because you’ll be paying much less than what you would pay to buy electricity from your utility company without solar panels.

Federal Solar Tax Credits

There are several federal solar tax breaks and incentives available from the federal government, as well as local governments, states, and utility companies. Solar panel systems are also becoming more accessible due to low-interest solar loans and $0 down installations.

How Does The Federal Solar Tax Credit Work?

The Federal Solar Tax Credit is a program that allows homeowners to deduct 26% of the cost of installing a solar energy system from their federal taxes. This deduction can be taken in the year that the system is installed, making solar energy systems even more affordable. Many states and local governments also offer their own tax credits and incentives for solar energy systems, making them an even better investment.

Solar Incentives

There are many other solar energy incentives that homeowners can take advantage of to make their homes even more affordable. Some states offer rebates for purchasing and installing solar panels, which are applied after the system has been installed. Many utility companies also have programs where they will pay homeowners for any excess electricity provided by the solar panels, often at a higher rate than what they would normally charge. This additional income can be used to help offset the cost of solar installation or put towards future savings. Tax exemption is another way that solar energy is made more affordable. In some states, homeowners can exempt 100% of the cost of a solar system from their property taxes.
