What Should You Look For in a Pennsylvania Solar Company?
Solar is a big investment, making choosing the right provider extra important. Here are some important factors to consider when comparing companies.
Solar Services
Check that the company you’re considering doesn’t just sell solar panels but also installs them. We recommend in-house solar panel installation rather than a third party because you’ll likely experience better communication and quality assurance. You’ll also get a more comprehensive labor warranty on the workmanship. Check if the provider only installs solar panels or if they also install solar batteries, inverters, and other equipment.
Warranties
Solar warranties include:
- Manufacturer’s warranty (or product warranty): This protects the individual solar system components in case of defects.
- Workmanship warranty: This covers installation in case of poor workmanship or faulty installation materials.
- Performance (or power production) guarantee: This guarantees the solar system’s output performs as outlined in your contract.
The best companies offer 25-year warranties in each case, though some limit their workmanship warranty to 10 years. We recommend finding a company that provides at least 20 years for each warranty type.
Payment Options
Solar companies offer a combination of these solar financing options:
- Full purchase: Purchasing your system in full at the time of installation gives you immediate system ownership and qualifies you for further incentives.
- Solar loan: A solar loan allows you to make monthly payments on your system but still lets you own your system.
- Solar lease: You’ll make set monthly solar system payments with a lease, but you won’t be able to own it, disqualifying you from most solar incentives.
- Power purchase agreement (PPA): A PPA allows you to make monthly payments with no money down, but you won’t own the system.
The best companies offer 25-year warranties in each case, though some limit their workmanship warranty to 10 years. We recommend finding a company that provides at least 20 years for each warranty type.
Customer Support
Customer service can make all the difference in whether you have a smooth experience. You want a provider that’s not only friendly but reachable, responsive, and helpful. Companies should provide multiple ways to reach them, such as phone, email, online chat, online portal, or mobile app. They should also be responsive across all of them.
Try calling, emailing, or messaging the provider and see how long it takes to reach the right person. Look at the customer support hours to see if you can reach someone on weekends and evenings. Lastly, consider how supportive customer support is. A provider that thoroughly answers all of your questions, looks for ways to save you money, and takes the time to get the best product for your needs should be at the top of your list.
Questions To Ask Your Solar Installer
We recommend asking solar installers the following questions before hiring them for your solar project:
- How long have you been in business?
- What licenses and insurance coverage does your business have?
- What certifications do you hold? Are you 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:
Our Conclusion
Pennsylvania residents have several great solar companies to choose from. The right one for you depends on your budget and priorities. We recommend SunPower as our top choice due to its high-efficiency panels, comprehensive warranty, 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. Check out our guide to how much solar panels cost for what to expect.
