As 60-celll 300 Wattage solar panels are the typical option for residential solar installations, one such solar panel can cost between $169 - $430. In this price range, we are sure you can find a solar panel of fine quality. If you pursue higher quality, the price will surely go higher.

In this guide, we will discuss not only “how much does a solar panel cost”, but also other costs that might add up to the total costs of solar panel installation costs, for example, labor costs, maintenance costs, interconnection fees, and so on, so that you can have a basic understanding of how much you will need to pay for a solar panel system for your home.

How Much Does It Cost To Install Solar Panels?

According to EnergySage, the average cost of a residential solar systeminstallation in the U.S. in 2022is $20,498. However, the actual cost can vary higher or lower, as every homeowner’s roof space, electricity needs, lifestyle, and budgets are different. Even when choosing a solar power system, the costs can vary due to many factors.

For example, how much does a 6000 watt solar system cost?

As we’ve mentioned at the start of this article, a 60-celll 300 Wattage solar panel costs somewhere between $169 - $430. Dividing 6000 by 300, you will figure out that 20 solar panels are needed for a 6000-watt solar power system. Multiplying that with the price range, you will get $3380 - $8600, which will be the estimated cost to invest in the solar panels of a 6000-watt solar panel system. However, a complete solar power system still require inverters, charger controllers, and other components, not to mention the labor cost for the installation process.

Generally, the overall cost of solar installation involves: 

- buying a complete solar power system: solar panels, inverters, charge controllers, screws, wires and cables, etc.

- Installation costs: installation materials and labor costs

- Fees incurred in the utility interconnection process

- Interest from the loan

Costs of the Equipment of A Solar Panel System

Breaking down the cost to install solar panels first requires you to know that different types of solar panels have varied pricing. Solar panels account for only about one-quarter of the cost of a solar project.There are three types of solar panels each with different construction, performance and cost.

Polycrystalline:These panels are blue in color and use multiple silicon crystals melted together. They are a bit less efficient than monocrystalline but are a more affordable option.

Monocrystalline: Monocrystalline are made from a single silicon crystal and typically have better efficiency and are smaller in size than polycrystalline. They also tend to be the higher cost option.

Amorphous solar panels: They are lightweight, flexible and have portable options, buthave much lower efficiency than Polycrystalline or Monocrystalline. They are also larger and require twice the space than monocrystalline panels.

System size

The number of panels you’ll need for a system is determined by how much energy your home uses. Typically, consumers aim to offset 100 percent of their electricity usage with solar to get their energy bills as low as possible. For example, a typical 2,000 square foot three-bedroom home will require a system with about (20) 350-watt panels with a cost of $15,000 and $40,000 including installation.

Most American homes need about 30 panels to cover 100 percent of their energy usage. Where you live may also impact how many panels you need. In areas where there are more peak sunlight hours, you may require fewer panels to generate the energy you need or vice versa for areas with fewer peak sunlight hours.


Inverters are solar components that convert the DC power your panels produce to the AC power your home uses. There are a few types of power inverters with varying equipment and installation costs. Inverters typically account for about 5-10 percent of a project’s cost.

Grid tied vs. offgrid systems

Grid Tied Solar Systems are tied to the electric grid. That means your home remains connected to the power grid and draws energy when solar panels or batteries are not producing. Grid tied systems also allow your home to send excess energy produced by solar back onto the grid, which means you can sell extra solar power for extra income to offset the solar cost. These systems need to be installed by professional installers, which means you have to pay the installation fees.

Off-Grid Solar Systems are, in most cases, only an option where there is no access to electricity from the grid. These systems are fully self-reliant and require batteries to provide power at night or when the sun isn’t out. Off-grid systems can be installed DIY, but you have to buy a solar battery.


Installation Costs

Installation fees includes the cost of:

  • Labor
  • Additional equipment like mounting brackets and cabling
  • Fees for permitting and inspection

If using a professional installer, installation represents a sizable portion of the cost of a solar project.

The material your roof is made of will also impact installation costs. Materials such as asphalt shingle tend to have lower installation costs, while materials like clay tile have higher installation costs. A flat roof surface requires supplementary brackets.

Grid connected systems will need to be permitted and inspected by either the local housing jurisdiction, the utility, or both. That’s why grid-tied systems are typically installed by professionals.

Permitting and inspection require fees that are bundled into installers’ estimates in most cases. There will also be an ongoing interconnection fee from the utilities to remain connected to the grid.


Maintenance Costs

Solar panel maintenance is typically not a significant expense. Modern panels are nearly self- cleaning with natural rainfall usually sufficient to keep them clean. At times you may need to clear your panels of tree debris or dust. You may want to hire a professional to do this. 

As for repairs and replacements,residential solar systems don’t have moving parts so equipment failures are relatively uncommon. However most solar equipment comes with 20-30 warranties that cover equipment failures and defects.

Financial Incentives

Incentive and rebates

Through 2022, the federal solar tax credit is 26 percent of system costs. In 2023 the credit goes down to 22 percent. Various other financial incentives are available to make solar more affordable forresidential customers. Incentives vary depending on where you live and are available through government agencies, utilities or both. To learn more about incentives, visit

During our research, we find that some professional incentive terms can lead to misunderstanding easily. In this regard, we make the chart below to offer you a clear overview and you can compare which policy can offer you real benefits in reducing your solar cost.

Solar cost per square foot

While some solar panels of the same wattage come in different sizes. In that situation, calculating the solar cost per square foot can make things easier. The cost per square foot can vacillate between $4 and $10.

How much do solar panels cost in pa?

The average cost of solar panels in Pennsylvania is $12,281 to $20,216 before applying for solar incentives. That means the average cost of solar panels in PA ranges from $2.64 to $3.56 per watt.

How much does solar cost in Texas?

On average, the solar panel costs in Texas is $2.77 per watt. That being said, a typical 6000 watt (6 kW) solar system can cost $11,647 after claiming the 30% federal solar tax credit now available. 

Commonly Asked Questions

How long to recoup costs?

It’s easy to calculate return on investment or ROI for solar. Just divide the total cost of your system (after incentives)by your average energy savings per month. ROI or “payback” time is measured in months and years. It tells you how long it will take to recoup your solar investment.

Even though solar may come with a substantial upfront investment, those costs can often be recouped in as few as 5 to 15 years. In that time, not only are you saving on energy, but you’re reducing your carbon footprint. That should be enough to get anyone excited about joining the clean energy community.

Next Step

Solar power, as one of the most affordable, accessible and reliable electricity for households, offers the best electricity alternative for faraway areas that cannot connect to the grid, as well as families that are longing to reduce their electricity bills. Installing an off grid solar power system or grid tied system will be the best practice to go solar.
