What Is The Cost To Install Residential Solar Panels?

It all starts with a critical ingredient: silicon, the second most abundant element in the depths of the Earth. This sand-derived material is cleaned and processed through extensive processing into microchips, which work as the heart of the solar cells.

These chips are treated and coated with other stuff to create photovoltaic cells, which can convert sunlight into electricity. When sunlight hits a photovoltaic cell, it excites electrons, kicking them into a higher energy state and generating an electric current. These individual cells are assembled into a solar panel, encased in a protective material to withstand the elements, and supplied with electrical hardware.

The Cost of Installing Residential Solar Panels

For most people, the main interest in solar panels is the cost. But the best way to think about the cost of solar is simply an interchange of the money they are already spending on electricity bills. Instead of paying the electricity bill, pay for your system, avoid future electricity price increases, and also help to protect the planet. Once your system is installed, its energy will be free.

Cost of Solar Panels by Type:

Here, we will discuss How much does it cost to install residential solar panels? Solar panels can be monocrystalline and polycrystalline.

Monocrystalline solar cells comprise the premium panel since they use the sun’s rays more effectively. However, polycrystalline panels are low-cost and can be a good choice for high-sunlight areas. The cost of solar panels can change with it’s type.

most common types of solar pannels

Type Per watt price 6kw price
Monocrystalline $1.00 – $1.5 $6000 to $9000
Polycrystalline $0.90 – $1.00 $5400 to 6000 dollar
Thin-film $1.00 – $1.5 $6000 to $9000

Factors That Affect Residential Solar Panel Costs

Many reasons can affect the average cost of solar panel installation. Some of these we will discuss are major cost-effecting factors.Factors That Affect Solar Panel Costs

Type of Installation:

There are several types of installation of solar panels that can affect the overall cost of the system. Roof installation is the most common, but ground installation is implemented in many places. This takes more labor and equipment and may increase the average cost of the system.

Type of Equipment:

A basic panel comprises a blue cell, a white back sheet, and a silver frame. Black frame modules will have a black back sheet or cell and are usually more expensive. Other equipment like batteries also affect the cost.

Roof Type:

Solar panels are installed on metal, shingle, and plan roofs. These all require different strategies to install and different numbers of labor. So this thing affects the average cost of solar panels.

Energy Consumption:

Solar panels are designed to produce energy, but more energy consumption requires more production, panels, and equipment. This increase in solar panels can increase the overall cost of solar panel systems.

Shading and Weather:

Weather is an important factor that affects the cost of solar panels. Solar panels are the best alternative to grid electricity in the cities where the sun rises every day, but in the cold areas, it’s different. These areas require more solar panels to produce the same energy. By these few factors, the weather is a considerable in cost changes.

Interconnection Price:

Interconnection refers to joining your solar panel system to the local power station. Each local electricity provider has specific requirements that must be followed, and some of these may affect the type of meter you need or the transformer upgrade required. The interconnection cost of solar panels is a considerable factor because it varies with equipment usage and the presence of solar panels in a city.

Residential Solar systems prices by states:

The cost of solar panel systems also changes with states and cities. Here, we will discuss a few general prices of different states of the USA. But this data is general. It may change at the time of purchase. We will read it now. How much does it cost to install residential solar panels?

Average Cost by Solar System Size:

Size always affects the average cost of the solar system. It varies between $6000 and 18000 dollars, but after increased prices, this rate changed to 6600 dollars and 22800 dollars. But with the 30% tax credit from the federal government, these prices decrease to $4600 and 16000 dollars. This is the price range of 6kw systems and 12kw systems.

KW size Average price without Tax credit Final Price after Tax credit
6kw $6,600 – 11,400 dollar $4,600 – $8,000
8kw $8,800 – 15,200 dollar $6,200 – $10,600
10kw $11,000 – 19,000 dollar $7,700 – $13,300
12kw $13,200 – 22,800 dollar $9,200 – $16,000

The average energy production depends on the area and sunlight.

Solar systems average costs:

The cost of solar panels has dropped suddenly in the last few years. After an unacceptable increase in electricity bills in the year 2022, the payback rate of the home solar system goes up rapidly. The 2023 Heatmap Climate Poll found that 13% of the US population already uses solar systems to fulfill their electricity needs, and 46% are planning for it.

The average cost of panes is nearly $1 per watt; by this, you can calculate the cost of the desired system. The most common system used in houses is a 6kw system, which costs between 6600 and 11000 dollars. The average cost of panels can be changed due to reasons such as Federal government Tax credit policies and changes with area and states. We will further discuss them in this article. So make sure to catch the end.

How much does it cost to install residential solar panels?

Based on a survey, the average cost of Solar Panels is between $15000 and 25000 dollars. But it is the cost of installation. The panel’s cost is one-third of the total cost. The higher your home’s energy consumption, the larger the solar panel system needed to meet your usage. For example, based on our average cost of solar panels at $3 per watt with installation, a 6 kW system will run you about $18,000, while a 12 kW system will double the cost.

Additional Solar Panel Costs to Consider:

Many hidden things can affect the overall cost of solar panels. These are insurance,  cleaning and maintenance costs. Sometimes, natural events destroy your solar panels, or sometimes it seem to be some emergencies that can affect its cost.

These hidden costs are important to know and plan for them, but they shouldn’t stop you from considering going solar. Most solar installers should factor these costs, such as insurance and utility charges, into your solar quote so you get a better idea of ​​how these hidden costs affect your investment.


As we get started, we put a question. How much does it cost to install residential solar panels? Then, we continue it and discuss it throughout the article. Hopefully, you got your answer, and now we are ready to conclude this article.

As we study, several main factors affect the cost of solar panel installation. Even installation is itself a factor that increases cost. The panel cost is $1, increasing to $3 per watt after installation. These costs changed by area and installation method. Different qualities also affect the cost, and some special circumstances increase this cost.

But after all of these, its payback period is amazing, and it pays for 25 years to 30 years. It saves your electricity bill, and its payback increases if utility companies change the unit rate immediately. If you still need clarification, it’s our opinion that shifting to a solar system is more beneficial than paying directly to electricity companies if you belong to hot areas.
