What Is the Solar Power World Top Solar Contractor in Pennsylvania List?
Solar Power World originally introduced the Top Solar Contractors List in 2012. Compiled annually, it celebrates the achievements of U.S. solar installers, developers, subcontractors, and installation companies within the utility, commercial, and residential solar markets.
Contractors are ranked by the number of kilowatts installed in the previous year. A direct reflection of real-world solar installation output and customer trust.
Solar panel installation companies on the list represent multiple market segments, including utility, commercial, residential, and off-grid. Eligible companies provide services in EPC contracting, development, construction, and installation, electrical work, and rooftop-specific installations.
According to Solar Power World and the Solar Energy Industries Association (SEIA), the U.S. solar industry was expected to see 14% growth in 2019, with over 12 GW of new solar power added to the grid — enough to power 2.28 million average American homes.
Much of that growth was driven by a surge in residential solar adoption and the urgency to complete solar projects before the 30% federal solar tax credit dropped to 26% in 2020.
As Solar Power World editor-in-chief Kelly Pickerel put it, "Solar power is becoming competitive with traditional electricity sources in more markets, and cities and states are demanding more renewable energy options. It's a great time to be a solar installer, and we're happy to highlight the best installation companies in the country on our list."
Why This Recognition Matters When You're Choosing Solar Companies in Pennsylvania
Pennsylvania has a lot of solar companies, but they are not all the same. Choosing the right one matters for homeowners and businesses. Solar panels last 25 years or more and usually come with a 25-year warranty. The company you pick now will be with you for a long time.
Here's what to look for when you evaluate solar companies:
1. Certification and Experience
The gold standard for solar panel installation companies is certification through the North American Board of Certified Energy Practitioners (NABCEP). Certified energy practitioners bring rigorous, standardized training that guarantees your solar panel systems are designed, installed, and commissioned correctly.
Look for companies with NABCEP-certified professionals on staff, and always choose an experienced solar installer with at least five years in the industry.
Always verify that any contractor is licensed and insured before signing a contract.
2. Equipment Quality and System Performance
2. Equipment Quality and System PerformancePennsylvania's heavy winter cloud cover and limited sun exposure make high-efficiency solar panels an absolute must. Cheap panels may cost less upfront, but they'll underperform during the months when you need them most.
Optimizing equipment to work in varying weather conditions is critical — what works in Arizona may not deliver the same solar savings in southeastern PA.
When reviewing solar quotes, ask about equipment efficiency ratings and guaranteed solar production figures. A reputable solar panel company will stand behind the performance of your solar system with documented guarantees.
3. Transparent Solar Financing Options
The upfront cost of going solar has never been lower, but understanding your options is still essential. Pennsylvania solar installers should be able to walk you through all available paths, including:
- Solar loans — Pennsylvania offers green energy loans up to $100,000 through the Pennsylvania Treasury's Bright Energy Savings Program, making it easier than ever for businesses and homeowners to finance a new solar system without draining capital.
- Solar lease and Power Purchase Agreement (PPA) — Also known as third-party owned systems, these options let you go solar with little to no money down. Under a power purchase agreement, a solar company owns and maintains the system on your property, and you simply pay for the solar energy it generates — often at a rate lower than your current electric bill.
- Federal tax credit — The federal solar tax credit (also called the Investment Tax Credit, or ITC) allows you to deduct a significant percentage of your solar panel installation costs from your federal income taxes. Consult a tax advisor for the exact benefit applicable to your situation.

4. Pennsylvania Solar Incentives and SRECs
One of the biggest financial advantages of going solar in Pennsylvania is the Solar Renewable Energy Credit (SREC) market. Pennsylvania's SREC market pays $30 to $40 per MWh generated, meaning a typical 5-kW solar system generates between $400 and $600 annually from SRECs alone.
These solar renewable energy credits are earned for every megawatt hour of clean electricity your system produces and can be sold on the open market.
Combined with net metering — which credits your electric bill for excess solar energy sent back to the grid — Pennsylvania solar incentives can dramatically reduce your payback period and improve the long-term return on your solar investment.
Don't overlook local incentives either. Many municipalities and utilities in PA offer additional rebates and programs that further offset energy costs.
5. Customer Reviews and Track Record
Read customer reviews on Google, EnergySage, and the Better Business Bureau. A company's reputation for handling everything from solar installation to post-install service says a lot about who they are. Solar customers should be treated as long-term partners, not one-time transactions.
The Right Solar Installer Makes All the Difference
There's a meaningful difference between the top solar companies and the few that simply show up in a Google search.
The best solar company for your needs will assess your energy consumption, recommend the appropriate system size, walk you through the full range of solar financing options, and keep you informed at every step of the process.
High-performance installations — such as those required by Pennsylvania's High Performance Building Program standards — demand expert planning and precise execution. From solar panel systems designed for maximum output to properly sized solar batteries for energy storage, every component matters.
How much energy your system produces over its lifetime depends heavily on the quality of your installer. An experienced solar installer who understands your local utility's net metering policies, knows how to claim all available solar savings, and can size your system to match your actual energy bills is worth every dollar.
