Reputation and Reviews

Venture has an A+ rating and accreditation on its BBB profile. According to customer reviews, the company provides high-quality workmanship on its solar panel systems and good customer support. However, some customers have raised concerns about the pricing and quoting process. They found it confusing to determine the total cost of their system and experienced frequent back-and-forth over pricing.

Some customers also noted that Venture focuses on premium products, leading to higher pricing even when unnecessary. We found several Reddit threads discussing Venture where other solar customers and installers mentioned similar experiences.

Sunrun Best Solar Panel Leasing
4.5

We chose Sunrun because of its experience and options for solar panel leasing. Sunrun also prioritizes code compliance through its BuilderChoice New Homes Program. This program gives customers a dedicated team to handle their project’s building and permitting paperwork, ensuring all equipment is installed to code.

How We Scored Sunrun

Sunrun earned 4.4 out of 5 stars based on our rating scale. Here’s a look at how it did in each category:

  • Solar equipment and services (15 out of 25 points): Sunrun lost points in this category for not offering roofing services or energy audits. 
  • Warranty and performance guarantee (19 out of 25 points): While Sunrun earned full points for its warranty coverage, it lost several for not having a performance guarantee. 
  • Reputation and certifications (13 out of 15 points): The provider rates well among sites such as BBB but doesn’t hold certifications with some top renewable energy organizations.
  • Financing options (13.5 out of 15 points): Sunrun offers a variety of payment options but doesn’t offer in-house financing.
  • Industry experience (9 out of 10 points): The brand’s years of experience make it far from a new solar provider, but it hasn’t been in business as long as industry leaders, such as SunPower.
  • State availability (8 out of 10 points): Sunrun lost points for not being available in all 50 states.
Pros and Cons
Pros Offers insurance protection for system damage or theft Provides 24/7 customer support Includes free maintenance on leased solar panels Cons May not be available in your state Limits its 25-year warranty to lease and prepaid customers Encourages customers to lease without explaining the drawbacks

Financing Options

✔ Full purchase
✔ Loan
✔ Lease
✔ PPA

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.

What Solar Incentives Are Available in Pennsylvania?

Solar panels are a big investment, but there are federal, state, and local programs that can reduce solar panel installation costs. Below are the key rebates and other solar incentives Pennsylvania residents can apply for. See a full list of Pennsylvania solar incentives

  • 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.
  • Net metering: Some Pennsylvania utility companies have net metering programs that allow you to return your excess energy to the power grid in exchange for 1-to-1 credits on your future bills. The Pennsylvania Electric Company (PECO) offers this kind of program.
  • Pennsylvania Alternative Energy Credit program: The Pennsylvania Alternative Energy Credit Program provides credits for specific amounts of energy produced by your system that can be sold to the state or businesses looking to invest in clean energy. Prices for these credits vary.

Our survey of 1,000 solar users showed that 75% took advantage of solar incentives to further their return on investment. Of that, 64% applied for the federal tax credit, 32% used a net metering program, and 30% benefited from a local rebate incentive.


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.

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.

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:

  • Consultation: You’ll choose from a virtual or in-person consultation to talk with a company representative about your energy needs, roof condition, and potential savings. Your installer will answer your questions, advise you on your system options, and provide a project estimate. Have a copy of your monthly electric bill handy.
  • Site survey: A technician will inspect your home and property to identify any issues that will impact installation or limit your system’s potential. The rep will advise you on any roof repair, tree removal, or other services needed to ensure a successful installation and determine the surface area of your roof.
  • Design and permitting: The company will design your solar array based on your roof assessment and energy needs. You’ll choose your panel specifics and system components. The company will provide you with a detailed quote and contract. Once you sign, the installer will submit necessary permitting paperwork.
  • Installation: Installers arrive with panels, wiring, racking systems, add-on components, and any other necessary equipment. Our survey takers reported installation most commonly taking just one day to complete. The solar company should provide timely updates for any delays in installation.
  • Inspection: Your installer will work with local building officials to inspect your system and ensure it meets codes. Scheduling could cause this step to take a few weeks. 
  • System activation: Once your system passes inspection, your installer will coordinate grid connection with your utility company. After approval, your system will be turned on and begin converting solar energy into electricity for your home.

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. Check out our guide to how much solar panels cost for what to expect.
