Methodology: How We Ranked the Best Solar Companies in Williams
EcoWatch's solar experts analyzed each solar company in Williams based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Williams
Below are some the criteria we examined specifically for Pennsylvania solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in Williams
The cost of installing a solar panel system has dropped immensely over the past few years, but it’s still a significant investment for most homeowners.The installation cost is just one important factor you should take into account when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:
- System size and type: Some models are more pricy than others, so the one you get can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
- Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 0 of the project cost. Your state and even local utility companies may also have incentives and rebates that you can use. Additionally, you can save about $14,000 over 20 years on your utility bills, not including incentives.
- The amount of sunlight your roof gets: If your roof gets limited direct sunlight, your solar panels won’t be able to generate as much energy, which will give you lower savings on electricity bills than someone with a roof that gets lots of sunlight.
- How much electricity your home consumes: Households that need plenty of electricity each month may need more solar panels and, therefore, more upfront cost, but will also enjoy more savings over time.
Because of solar panels now being cheaper than ever as well as several solar incentives, they are a sound investment for the majority of homeowners.

EcoWatch's Williams, PA Solar Company Rankings FAQs
What is the top solar panel company in Williams?
In Williams, Exact Solar is the best local solar company. Our team of experts rates it 5.00 stars, so it's a solid choice if you're looking to add solar panels to your home.
Are solar panels actually bad for the environment?
Solar panels can be bad for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Making solar panels needs a lot of energy as well. The energy payback period is about 1 to 4 years.
How long does it take for solar to pay for itself?
The average payback period for solar panel installation is about 16.7 years, but the exact period varies by local electricity costs, incentives and net metering programs.
How often do solar panels have to be replaced?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is their energy production will have decreased by about 0.8% each year since installing them. You can opt to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.
