Factors that Affect Solar Panel Costs in Philadelphia

The cost of installing a solar system in Philadelphia can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The biggest one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power generation use better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,550. The brand and type of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Solar panels can save you money on energy bills over many years, but they can also be a big investment. That's why many Philadelphia homeowners decide to finance their solar panel systems to make paying for solar more affordable. While solar loans make switching to solar energy more accessible for Philadelphia homeowners, they can also raise the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The solar company you hire to handle your switch to clean energy can have an effect on your total costs. There are about 3 solar installation companies operating throughout Philadelphia, and each can charge varying amounts for labor and equipment. Larger national companies usually have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

The solar company you go with will be a major factor in determining not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should take into account, including:

  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, including when the site survey will be done and how long it will take.
  • Contract: It's important to look over your solar installer's contract closely to understand what services they will provide, what the warranty covers and what you can expect about your solar system's energy production.
  • Solar Panel Brands: Different companies carry various brands and types of panels. If you know you want a specific brand, make sure the solar company you're considering has it.
  • Warranty: If you're concerned about the longevity of your solar panel system, checking if your installer offers a 25-year, all-inclusive warranty can help put you at ease.

EcoWatch's Philadelphia, PA Solar Cost FAQs

How much does it cost to install solar panels in Philadelphia?

This is a hard question to answer exactly, because the cost depends on many factors. Broadly speaking, it costs about $12,750 for a 5-kW system and $25,500 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy needs. On the flip side, you can spend less if you go with a smaller solar panel system or less efficient solar panels.

Can you get solar panels for free in Philadelphia?

A solar panel system isn't free in Philadelphia, but there are some options that can make getting them more feasible, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can help lower the cost.

How much can I save on energy bills after switching to solar?

It is possible to eliminate your electricity bills with solar panels, but for most homeowners in Philadelphia, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you'll want to check with a local solar installer to see how many panels can fit on your roof.

How long do solar panels last in Philadelphia?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
