Factors that Affect Solar Panel Costs in Philadelphia

For many Philadelphia homeowners, the decision to install solar panels depends on cost. However, the range of solar installation costs can be quite wide in Philadelphia, with typical prices between $20,000 to $40,000. There are various factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of installing solar panels. For that reason, it's crucial to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use. The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more over time on your power bills. Additionally, extra products, such as solar batteries, can bump up your total well above the Philadelphia average.

Solar Financing Terms

Solar panels can save you money on utility bills over time, but they can also be a big investment. That's why many Philadelphia homeowners choose to finance their solar panel systems to offset upfront costs. When trying to figure out your overall cost, you should also calculate the interest you'll pay if you opt for a solar loan. Also, paying more on your down payment can lower the total interest paid over time.

Solar Panel Installation Company

The solar company you choose to handle your switch to sustainable energy can have an effect on your total costs. There are about 3 solar installation companies in Philadelphia, and each can charge different amounts for labor and equipment. Additionally, some companies in Philadelphia know more about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The solar panel company you choose will influence not only your total costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should keep in mind, including:

  • Warranty: Warranties that provide coverage for defective panels and repairs over around 25 years are the gold standard in the business, and offering such a warranty is one mark of a quality company.
  • Solar Panel Brands: Different companies will have various brands and kinds of panels. If you prefer a specific brand, make sure the solar company you're considering has it.
  • Installation Process: Get details from your solar installer about the installation process and what to expect, including when the site survey will be done and what the project timeline is.
  • Contract: When reading through your solar installer's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios such as a system component breaking or if the company goes out of business.

EcoWatch's Philadelphia, PA Solar Cost FAQs

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

The average cost of solar panels in Philadelphia is about $12,750 for a 5-kW system and $25,500 for a 10-kW system before the ITC, but the actual cost will depend on things such as the type of solar panels you want, what size system you need and how much energy you use.

Should I lease or buy solar panels in Philadelphia?

Leasing solar panels can be an attractive choice, because it typically comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better way to go if you want to maximize your savings.

Can solar panels significantly reduce my electricity bills?

Solar panels can potentially eliminate your electricity bills depending on your location and how much sunlight your home gets. Even if it doesn't get rid of them completely, you can save a lot of money on your bills, about $814.92 per year.

How often do you have to replace solar panels?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can keep using them at a lower efficiency.
