Solar Panel Installation Cost Breakdown

Many components go into installing a solar panel system. This includes calculating your power needs and surveying your home to make sure your roof can handle the load. Then the site is , and the panels are mounted onto a frame on your roof. They are then connected to the inverters, which are installed on the outside of your home on the other side of your electrical panel.

Most installers quote a single price for the materials and labor for this project. However, the labor generally breaks down to between $3,000 and $5,000 for the average 6 kW system, or between $0.50 and $1.20 a watt for installation costs out of the total $2.50 to $3.50 a watt costs for the total system. Your labor costs are influenced by various factors, including the roof pitch, roofing materials, inverter type, and panel type. Thin-film panels with micro inverters are faster and easier to install than monocrystalline panels with string inverters. So, labor for the first example would be lower than for the second.

The following is the percentage breakdown of the total cost:

A Solar Panel System With Battery: Components And Function

For every PV system with a battery storage, there are generally 4 primary components. The solar panel, which weve described already. A controller, which is what regulates the amount of electricity in the system, but particularly to the battery.

You didnt think the power was directly feeding the needs of the home 24 hours a day, did you? No, but if an energy storage battery is in place, then the solar electricity generated by your system can be stored for later use.

The last primary component is the inverter. Energy stored in a battery or coming directly from the PV panels requires conversion from DC electrical current to AC, in order to power most modern conveniences. Thats what the inverter is for. The two examples of popular inverter brands are SolarEdge and Enphase.

Its helpful to understand there are essentially two types of systems you would install for a home: off-grid and on-grid. Off-grid is perhaps what most who are new to solar power conceive a system to be.

It means all power generated from the PV system will be used solely to power the structure it is connected to. Whereas on-grid systems feed to the local utility provider, and then back to the home in a metered process.

Each of the two methods have their advantages and disadvantages. Because storing energy inevitably leads to wasted energy, it is usually far more cost effective for a homeowner to go with a grid-tied system.

Cost To Add Solar Panels To An Existing System

Solar Panels Cost Per Sq Ft

The cost of adding solar panels to an existing system is around the same as a new installation – about $2.50 to $3.50 a watt installed. The key is whether you can expand the existing system. Typically, roof-mount systems cannot be expanded much. Ground systems can be expanded if you have the space. This is a common situation in off-grid setups or when switching from grid-tied to off-grid. In these cases, you need to expand your system.

A 6 kW or 8 kW grid-tied system on most homes is not easily expanded because it will already take up most of the available space on the roof.

In some instances, you may be able to upgrade your existing panels to those with higher wattage. This has a cost closer to $3.50 a watt because these panels cost more.

Tesla Solar Installation Cost

Tesla solar panels cost $2.21 a watt. This translates to $10,500 to $17,520 for a 6 kW system fully installed. Several factors impact the installation costs. These include your location, how much shade your property gets, roof pitch, and the panel and inverter types. Tesla makes a range of different panels and, in recent years, has aggressively pushed the market to make panels more widely accessible. They also carry a full line of batteries for backup systems as well.

Different Solar Panel Cost For A 3000 Square Foot House

We have three major types of solar panels based on manufacturing technology: monocrystalline solar panel, polycrystalline solar panel, and thin-film panels.

Polycrystalline panels have efficiency lesser than monocrystalline by a figure of 20% but they are also 20% cheaper so price range for installing polycrystalline solar panel is:

* 400W per panel * = $18240

* 400W per panel * = $40320

Considering that thin film panels are 50% less efficient than and cost between $0.75 and $1 per kW.

* 400W per panel * = $8550

* 400W per panel * = $18000

How Much Will The Whole Installation Cost Me

While it can be useful to know the price per solar panel, the real price comes from the entire solar power system and the installation. We are not a DIY-focused site, so for this cost analysis we are going to focus solely on installation costs through a certified solar installer.

Beyond just the cost of solar panels, there are many costs that go into a full-scale solar installation on your home. Here is a quick breakdown of all the costs that go into an installation:

  • 25% Solar Panels
  • 45% Operational Costs

We will do a future post with a full breakdown of these costs, but what is the actual cost of a solar power installation on your home?

Lets start by looking at the average installation. The average installation on an American home is a 5 kilowatt system. For 2020, the average cost per watt of solar systems in the US is $2.96 cents.

So lets do the math! If we multiply 5,000 watts by $2.96, we get $14,800.

But wait, dont forget about the Federal Solar Investment Tax Credit! With this credit , you save 26% of your total solar installation cost through a tax credit. When we take this 30% credit out of $14,800, we arrive at $10,952.

The average cost of the average solar system in the United States is approximately $10,592 after available tax credits.

How Many Solar Panels Will You Need

Introducing A-Series Solar Panels: The Next Big Step in Solar

To know how many solar panels you will need, you will want to determine how much electricity you use in your home daily.

Modernize recommends discussing these factors with a trusted solar contractor. For ease, bring your electric bills with you to a consultation or calculate how much energy you use per day ahead of time by taking your monthly kilowatt usage and dividing it by 30. For context, the average house in the United States uses about 900-kilowatt hours a monthroughly 11,000 kWh a year.

Ultimately, the number of panels you purchase matters because it contributes toward the amount of kW of electricity produced each day. In turn, the more of your electricity costs you want absorbed by solar energy, the more panels you will need. If you only want a portion of your power to be produced by solar panels, you wont need as many panels.

What Is The Roi On Solar Panels

You can calculate the return on investment for installing solar panels by calculating your total payback. Calculate the amount you spent to install a solar panel system and then figure out the amount you will save on energy bills monthly.

These two numbers show how quickly your savings will cover your initial costs. Electricity rates will vary by region, being higher in the Northeast than in the Northwest. Solar tends to be more cost-effective where electricity prices are high and sunshine is abundant.

In a March 2021 Modernize survey, 40 percent of homeowners said they are actively pursuing home improvement projects to save money on their utility and electric bills. Installing solar panels is an energy-efficient way to save money on energy bills for the long-term.

On the other side of the coin is your homes resale value. A Zillow analysis showed that solar panels can increase a homes value by up to 4.1 percent.

How Does The Irradiance Per Square Foot Effect A Solar Installation

House Logic says

A typical two-story, 2,300-square-foot house with a medium-pitch roof has a roof area of about 1,500 square feet. Double that if the house is only one story.

Going back to the example solar panel I used earlier in the article with a square footage of 20.05. You would be able to fit 74 of them onto the typical two-story house. This means you would have a potential total hourly square foot energy collection of 31.02kWh.

Back to reality now, the average American household uses about 29.00kWh per day. There is an average of about 6 hours of full sunlight per day. If you would like to check the average hours of sunlight per day your State receives. You can do that here

Using our theoretical 419.25w per hour panel to cover the 29.00kWh per day 15 solar panels are needed.

The Seasons

During the summer, irradiance isnt a problem. But from the fall to springtime irradiance per sq. ft is much lower. You can take a look at the irradiance map here U.S. December Solar DNI Average

This could mean that in the States where the average irradiance is low. You may not get the performance you were expecting from your solar installation. If you were thinking about a stand-alone installation . You might want to also want to think about installing a backup generator.

Solar Panels Cost Per Square Foot Guide

So, how much do solar panels cost per square foot?

Well, this is not always a straightforward situation as many of us might want it to be.

The cost of solar panel installation is influenced by various factors.

For example, you might want to look at the size of your house and its energy needs, location, solar panel brand, etc. Labor costs will also determine your total installation costs as some professionals might be more expensive than others.

This means that even with the cost of a solar panel, so many other things come into influence the overall installation costs.

Generally, the average solar panel installation cost ranges between $10,626 and $26,460, after tax credit. These are costs for a system between 6kW to 12Kw, which is capable to power most average homes.

As for the return on investment, it takes between 7 and 12 years to cover that cost. This is considering that solar energy will help you save $600 to $2,000 annually on electricity costs.

Effective Means Of Capturing Awesome Power

Cost of Solar Panels per Square Foot

Each hour, there are 122 Petawatts of solar energy delivered to the earth from the sun. To help put this in perspective, this is around 10,000 times the power consumed by all humans in one trip around the sun .

In the last century, we are just learning to tap into solar energy in a meaningful way. Efficiency of solar cells and ultimately arrays is the ongoing work of research scientists. Highest efficiency arrays are either too experimental for mass production or are relegated to government and major industry purposes.

For a home, the process of solar generation into electrical power requires other technologies to be in play. Foremost is the placement of the solar arrays:

Positioning toward the south is a given in North America. Thus, rack mounting panels onto a southern-facing exposed and unobstructed rooftop is the norm. Though, not necessarily the most efficient.

A solar panel mounted on the ground that tracks the movement of the sun is currently the most efficient way to harness solar energy through a PV system. It can, rather easily, power itself, plus have most of the power left over to supply solar electricity for many other applications.

Yet, this type of system is generally more costly upfront, is not suitable to all forms of residential living, and requires much more ongoing maintenance than rack-mounted or rooftop systems.

Solar Energy Cost Per Kwh

Residential solar energy costs $0.08 to $0.10 per kWh on average, and commercial or utility-scale solar power costs $0.06 to $0.08 per kilowatt-hour. Prices include the Federal Solar Tax Credit and vary drastically based on the amount of sunlight and type of solar panels installed.



$2.53 $3.15

$1.06 $1.83

These figures represent the Levelized Cost of Electricity , which is the average revenue per unit of electricity generated that would be required to recover the costs of the solar panels over their life expectancy. Consult with solar installers to calculate savings.

Commercial Solar Panel Cost Per Square Foot

The size and the type of your commercial solar system will determine the cost of solar panel cost per square foot. The larger the solar system, in kW or MW, the higher the cost.

For example, a commercial solar system between 10 kW and 2 MW will cost around $1.83 per watt. Larger systems beyond 2 MW costs a bit lower around $1.06 per watt.

If you want to install a solar system for your small or mid-sized business, it will cost you around $43,000 to $175,000 for systems between 25kW and 100 kW.

With commercial solar systems, you will likely recover up to 45% of your solar panel costs in one year from rebates and tax credits.

Do Solar Panels Increase Home Value

At first glance, you may be wondering if installing a solar panel system is worth it given the price tag. But research has shown that installing solar panels can greatly increase your homes property value.

In fact, its reported that on average that your resale value is close to $6,000 for each 1 kilowatt installed. The increase can depend, however, on factors like where your home is located and how big it is. States with active solar markets yield higher returns, and larger homes generally see a bigger return of investment.

For many potential buyers, a solar system represents a home upgrade just like an added room or renovated kitchen. Solar panels can also be more cost-efficient than other electrical options, which can be enticing to potential buyers.

And beyond that, solar panels represent a commitment to clean energy alternatives, which is becoming increasingly important for all Americans.

Residential Pv Solar Panel System Cost

How Much Do Solar Panels Cost? – Cost of Solar Panels in 2021 Explanation

The high upfront costs, which typically includes a concurrent installation of a new roof, are usually the reason most people dont go with solar energy. $15,000 to $25,000 in upfront investment can be a lot when you compare it to a yearly bill of say $1,200 for home energy costs.

In 2022, the national average cost per watt installed can range between $2.80 and $3.50 before the federal solar tax credits. The cost per watt can wary from company to company, and depending on the system size and your homes location. The cost per watt installed can be significantly higher if you go with a large national installer like SunRun, Vivint Solar, or SunGevity.

For a typical complete 6kW residential PV solar system installed at $2.80-$3.50 per watt by a small local installer, the total average cost can range between $16,800 and $21,000, before the federal solar ITC rebate and other incentives. Yet, if we factor in the 26% federal tax credit rebate through 2022 , then the final cost will range between $13,320 and $15,540. Still, there are enough factors to consider that could lower or raise the total price of the system.

Solar Panel Price By Cell Type

Depending on the company you contract with, you may have a choice of solar cell types. There are three main types – polycrystalline, thin-film, and monocrystalline. Of the three, monocrystalline panels are the most common. However, in terms of energy output, monocrystalline performs the best. For this reason, its also one of the more popular options. Thin film and polycrystalline both have slightly lower costs than monocrystalline, and may be an option for those on a very tight budget, but they tend to have lower energy output. For many homes, you may not notice much of a difference between them, but in terms of cost and total energy output, there are variations. There can also be differences in the way that they look. Below are the average costs per watt for the three different types.

Type of Cells
$0.60 – $1.20
