Reputation and Awards
Sunrun has an A+ rating with BBB and is accredited. The provider earned DroneDeploy’s 2022 Guardian of Safety Award for using drone technology with its site assessments. In 2021 and 2022, Sunrun received 14 awards from Comparably, including Best Company Culture, Best CEOs for Diversity, and Best Company for Women. One concern with Sunrun is its push for customers to finance their system through a solar lease without explaining the drawbacks. Leases and PPAs prevent homeowners from ever owning their system or qualifying for solar incentives.
Note: In July 2024, SunPower notified dealers it would be halting all new shipments and project installations. The company also noted it would “no longer be supporting new Leases and PPA sales nor new project installations of these financing options.

- Federal solar tax credit: The federal tax credit, also called the Investment Tax Credit (ITC), allows you to receive a tax deduction equal to 30% of your solar installation costs. This rate will reduce to 26% in 2033.

What Should You Look For in a Pennsylvania Solar Company?
Going solar is a big investment, so finding the right provider is key. Let’s dive into the essential factors to consider when comparing solar companies.
Solar Services
Look for companies that offer comprehensive services beyond just selling solar panels. This includes installation, system design, and ongoing maintenance. We recommend choosing a company that uses in-house installers instead of third-party contractors. This typically results in better communication, quality assurance, and a more comprehensive labor warranty.
- Available products: Some providers go beyond solar panels by offering additional products like solar batteries, inverters, and EV chargers. Bundling these components can lead to cost savings. Also, check that the installer supplies notable, highly efficient solar panels. This extends your solar panels’ lifespan and long-term performance.
- Energy monitoring: Look for companies that offer remote system monitoring, whether through an in-house platform or a mobile app, to help you track energy production and system performance.
- Installation process: Determine if the company uses its own team for installations or relies on third-party contractors. In-house installation teams typically offer better customer service and more seamless warranty support.
Warranties
Warranties are a critical consideration since they protect your investment over the long term. Here are the key types to look for:
- Manufacturer’s warranty: This type of warranty covers defects in the solar panels and components, typically for 25 years.
- Workmanship warranty: This covers installation errors and issues related to faulty materials. Look for at least a 20-year warranty.
- Performance guarantee: This guarantee ensures your system produces the expected amount of energy. A good performance guarantee provides at least 20 years of coverage.
Payment Options
Solar installers offer several financing options for going solar:
- Full purchase: Paying in full upfront gives you complete ownership and access to all available incentives.
- Solar loan: This allows you to finance the system while retaining ownership.
- Solar lease: You make monthly payments, but you don’t own the system.
- Power purchase agreement (PPA): A PPA is similar to a lease but based on the electricity your system generates.
According to our recent survey of solar customers, 49% chose to pay in full upfront, 23% got a loan, 11% leased, and 17% financed through a PPA. Choose a payment plan that fits your financial goals.
Customer Support
Companies should provide multiple ways to contact them—by phone, email, online chat, and through a mobile app. Test their responsiveness by reaching out with questions and seeing how quickly and thoroughly they reply.
Questions To Ask Your Solar Installer
Before choosing a solar company, ask the following questions:
- How long have you been in business?
- What licenses and insurance coverage does your business have?
- What certifications do you hold? Are you North American Board of Certified Energy Practitioners (NABCEP)-certified?
- Do you assist with permitting or applying for solar incentives?
- Does your company use all in-house technicians or third-party contractors?
- What financing options do you offer?
- Will I need additional services before my solar installation, such as roof repair or tree removal?
- What kind of warranty coverage will come with my panels and your labor?
- Can you show me photos of your work or provide customer testimonials?
How Can You Save Money on Solar?
Pennsylvania solar energy costs approximately 30 cents more per watt than the national average of $2.66 per watt. Save money when switching to solar by following these tips:
- Consider your home’s energy needs: There’s no need to invest in a large system or incredibly high-performing panels if your energy needs are minimal. Your solar provider should be able to advise you on the system size and type you need to cover your electricity usage while getting the most ROI.
- Get multiple solar quotes: You can get a quote online or by phone. We suggest getting a quote from a few companies to compare pricing before committing.
- Go with the right financing option: Always ask about your financing options, such as policy terms, lender choices, money down, and interest rates. Choose a financing plan you’re comfortable with that makes long-term sense.
- Take advantage of solar incentives: Not applying for the solar incentives you qualify for leaves money on the table, potentially thousands of dollars.
What Should You Expect During a Solar Installation?
The solar installation process will vary slightly by company, but you’ll typically go through these steps:
- Consultation: Whether virtual or in-person, you’ll talk with a company representative about your energy needs, roof condition, and potential savings. Bring a copy of your monthly electric bill to help calculate your energy needs.
- Site survey: An installer will inspect your home and property to identify any issues that will impact installation or limit your system’s potential. This may include checking your roof for damage, analyzing its surface area, and identifying trees that might block sunlight.
- Design and permitting: Once your roof is deemed suitable, the company will use your roof assessment to design your solar array. You’ll have a say in the type of panels and inverters used. The installer will provide the necessary engineering documents and submit permitting paperwork to local authorities.
- Installation: A crew of installers will mount the racking on your roof, install wiring throughout the system, secure the panels to the racking, and connect the system to your electric meter. An average residential solar installation should take one to two days.
- Inspection and activation: Once your system is installed, it must pass inspection to ensure it meets building codes and industry standards. Once it passes inspection, your utility company will provide permission to operate (PTO), allowing you to activate your system and begin generating electricity.
Our Conclusion
Roughly 96% of our surveyed solar customers said they felt making the switch to solar power was worth it, and 82% said their installation increased their property value. Pennsylvania residents have several great solar companies to choose from if you’re ready to see what you could gain. The right one for you depends on your budget and priorities. We recommend Palmetto due to its high-quality panels, excellent customer support, and positive customer ratings.
Carefully review a company’s website, warranty, pricing, and customer reviews before deciding which to hire for your solar project. We suggest getting a quote from at least three providers to compare price versus product.
