Residents of Pennsylvania may find many benefits in installing solar panels. Pennsylvania has a variable climate with hot summers and cold, snowy winters. With higher-than-average energy costs, heating and cooling your home year-round can be expensive. Solar panels reduce your energy costs, and residents can still benefit from solar energy even with an average of 179 sunny days per year.

The state average to install solar panels in Pennsylvania is $14,640 to $19,560, with most homeowners paying $17,100 for a 6kW system using monocrystalline panels on a roof. This project’s low cost is $4,880 for a 2kW system using thin-film panels on a roof. The high cost is $53,000 for a 10kW system with monocrystalline panels using full battery backup on the ground.

Average Cost of Solar Panels in PA by Type

Solar panel systems can be installed in two ways. You can remain tied to the electrical grid, allowing you to use the grid’s energy at night or when your system is not operating at peak efficiency. You can also install your panels in an off-grid setup with a much larger system, battery backup, and an additional backup system, such as a generator or wind power.

Most residents are tied to the grid in Pennsylvania. You can go off-grid in Pennsylvania, but there are very strict rules. You must have a religious exception - the state has a large population of Amish - or your home must be a recreational cabin. Going off-grid is subject to strict regulations, even under these circumstances, and most residences do not meet the requirements.

If you meet the requirements, off-grid systems must be much larger than grid-tied systems. They are also more expensive due to the size and battery backup. Below are the average costs to install a solar panel system on your home in a grid-tied and off-grid scenario in Pennsylvania.

Solar Panels in PA Cost per Square Foot

While your home size does not directly influence your system size, they can be loosely correlated. While you may have a range of energy needs, the larger the home, the higher its energy needs. This means your solar panel system is likely larger.

You can install smaller systems to offset your energy costs. You can also install much larger systems that meet all your home’s energy needs with room for growth. While larger homes typically have larger systems, there can be an overlap. Below are the average costs to install a solar panel system on homes of varying sizes.

Cost of Solar Panels in PA by Cell Type

Solar panels can be grouped into polycrystalline, monocrystalline, and thin film. Monocrystalline panels are the most common and expensive. Monocrystalline panels typically produce the best output and work in bright sunlight. They have a matte black finish for a sleek appearance.

Polycrystalline cells are made from fragments of silicon crystals, while monocrystalline panels are made from whole crystals. Polycrystalline panels are less expensive but less efficient than monocrystalline panels. They are also a brighter blue, which some people may not like.

Thin-film panels are the lowest profile. While they work best in overcast areas, they are less efficient than monocrystalline panels. They are also less expensive than monocrystalline panels. Below are the average costs for installing a 6kW system using the 3 solar panels.

Labor Cost to Install Solar Panels in Pennsylvania

Labor costs to install solar panels in Pennsylvania range from $0.81 to $0.93 per watt. Costs vary depending on many factors, including region, panel and inverter type, and installation location. Labor costs are generally higher in urban areas than in less-populated spaces. For example, installing the panels in Pittsburg is more costly than installing them in more rural spaces. Also, the area you install the panels on can also influence the labor cost. Ground installations are more labor-intensive than roof installations, impacting your final costs.

Which Direction Should Solar Panels Face in Pennsylvania?

The best position for your solar panels in Pennsylvania is to the south. However, you can install them facing southwest or southeast without sacrificing much energy output. You can position them to the west for homes not aligned in these directions. Speak with your installer about the best position for your solar panels and what other things may be done to maximize output.

Cost of Solar Panels in Pennsylvania by Location

Most solar panels installed in Pennsylvania are on roofs. This is the most common and cost-effective method of installation. However, you can install the panels on a ground-mounted system to maximize light exposure if your roof cannot support the weight, you have an oversized system, or your home does not face south.

Ground-mounted systems are more expensive to install than roof-mounted systems. Ground system arrays tend to be more costly than roof arrays. Running wires from the ground system to the home often involves trenching to bury the wires. This can lead to higher labor costs. Below are the costs to install a 6kW solar panel system in Pennsylvania on the roof and ground.

System LocationAverage Costs (Installed)
Roof$14,640 - $19,560
Ground$17,850 - $23,600

Pennsylvania Solar Tax Credit 2022

While Pennsylvania does not have specific tax credits for residents who install solar panels, the federal government offers a tax credit in 2022 to homeowners who install solar panels this year. This credit value is equal to about 30% of the cost to install your system and is claimed when you file your annual taxes. The credit you should receive on your taxes for a 6 kW system amounts to $4,392 to $5,868​, depending on the system cost.

Pennsylvania Free Solar Program

Two programs in Pennsylvania may help you install solar panels at no upfront cost. These are the Power Purchase Agreement (PPA) and the PA Sunshine program.

In the PPA, eligible homes can have solar panels installed on their homes at no cost to them. You pay for the energy produced by the solar panels, purchasing solar power for your home rather than strictly purchasing grid energy. Residents using this program save money on energy in most cases.

The PA Sunshine program can provide low or no-cost solar panels to eligible residents who meet certain criteria. These include income caps and living in an area that the census has declared underserved by solar energy. If you fit these requirements, speak to your local municipality for more information.

Solar Inverter Cost by Type

Your system also needs solar inverters. Inverters take the energy produced by your solar panels and turn it into energy your home can use. They come in a few types.

String inverters are one of the most common. Several solar panels are grouped into a string, and several strings may tie to a single inverter. This inverter is generally located in the basement or another accessible area. While they are more costly per inverter, you do not need as many as other types. The downside is that the entire system may fail if one string fails.

Power optimizers can be used with string inverters. You need one optimizer for each solar panel. They even out energy output from the panels and are useful if you have a complex roof where some panels may go into the shade.

Microinverters are installed one per panel, usually near the panel like power optimizers. You need 20 microinverters with 20 panels, so while they are less expensive than string inverters, you often need more. Their benefit is that if one panel stops working, the rest of the system is unaffected.

If you have a battery for your solar panel system, you also need a battery inverter. These convert energy from the panels into energy the battery can store. You need one battery inverter for each battery. Below are the average costs for each inverter type.

TypeAverage Costs (Materials Only)
Power Optimizer$125 - $150
Microinverter$150 - $215
String Inverter$1,000 - $2,000
Battery-Based$2,000 - $2,300

Cost to Run and Maintain Solar Panels in PA

Maintenance for solar panels in Pennsylvania is fairly easy. These panels should be inspected regularly for worn or damaged areas that may impact energy output to make timely repairs. They should also be cleaned regularly. Most people combine these services on twice-yearly visits. This has an average yearly cost of $300 to $700, depending on how many panels you need cleaned.

Tesla Solar Roof in Pennsylvania Price

If your roof is older and must be replaced before installing solar panels, you may want to consider a Tesla solar roof. Tesla solar roofs cover your entire home with inactive and photovoltaic tiles. This can produce the energy you need with a subtle and seamless appearance than installing solar panels on the roof. You can also use one or more of Tesla’s Powerwall batteries as a backup system. Depending on your home’s size and amount of inactive tiles, this system costs between $40,000 and $65,000 in Pennsylvania for the average 2,000 to 2,500 sq.ft. home.
