Pennsylvania Solar Panel Installation Services

Frequently Asked Questions

• How do solar panels affect my property value in PA?

  Installing solar panels can significantly increase your property value. Studies show that homes with solar energy systems sell for more than those without. Additionally, Pennsylvania offers a property tax exemption for solar energy equipment, ensuring that the added value from solar panels does not result in higher property taxes​​.

• What are the main incentives for solar energy in Pennsylvania?

  Pennsylvania offers several incentives to make solar energy more affordable:

  • Solar Renewable Energy Credits (SRECs): Homeowners can earn and sell SRECs to utilities, providing an additional revenue stream​​.
  • Net Metering: Allows homeowners to receive credits on their utility bills for excess electricity generated by their solar panels, which offsets future utility costs​.
  • Federal Tax Credit: The federal ITC provides a 30% tax credit on the cost of the solar system, significantly reducing the upfront cost​.

• Do you have to clean solar panels?

  Yes, cleaning solar panels can be important to maintain their efficiency. Dust, dirt, pollen, bird droppings, and other debris can accumulate on the surface of solar panels, reducing their ability to capture sunlight and generate electricity. Here are some key points regarding the cleaning of solar panels:

  1. Impact on Efficiency: Dirty panels can reduce energy output by up to 20% or more, depending on the level of soiling and local environmental conditions.
  2. Frequency: The frequency of cleaning depends on your location. If you live in a dusty area, near construction sites, or in an area with heavy pollen, you may need to clean them more often. Generally, a bi-annual cleaning schedule is sufficient for most residential solar panel systems​​.
  3. Self-Cleaning Factors: Rain can naturally clean some of the dirt off the panels, but it may not remove all debris, especially in areas with minimal rainfall. Regular inspection is recommended to ensure optimal performance​.
  4. DIY Cleaning: Homeowners can clean their solar panels using a soft brush, squeegee, and mild soapy water. It’s important to avoid using abrasive materials or harsh chemicals that could damage the panels. Always follow manufacturer recommendations for cleaning​​.
  5. Professional Cleaning: For those who prefer not to clean the panels themselves, professional solar panel cleaning services are available. These services ensure that panels are cleaned safely and effectively, maximizing their efficiency​.

  By keeping your solar panels clean, you ensure that they operate at maximum efficiency, providing the best return on your investment. Regular maintenance and cleaning can significantly extend the lifespan of your solar panel system.

• How are solar panels attached to the roof?

  Solar panels are securely attached to the roof using a method that ensures both the stability of the panels and the integrity of the roof. Here are the general steps and components involved in attaching solar panels to a roof:

  1. Roof Assessment: Before installation, a professional will assess the roof to ensure it can support the weight of the solar panels and that it receives sufficient sunlight. The roof’s condition, angle, and material are evaluated.
  2. Mounting Hardware: The installation begins with mounting hardware, which consists of rails and brackets specifically designed to hold the panels in place. These components are usually made from aluminum or stainless steel for durability and corrosion resistance.
  3. Flashing: To prevent water leaks, flashing is installed at the points where the mounting hardware penetrates the roof. Flashing is a waterproof material that ensures the roof remains watertight.
  4. Attachment to Roof: The mounting hardware is securely attached to the roof rafters or trusses using lag bolts or screws. These fasteners penetrate the roofing material and the roof’s structural members, providing a strong anchor for the solar panels.
  5. Racking System: Once the mounting hardware is in place, a racking system is installed. The racking system consists of rails that run horizontally or vertically across the roof. The solar panels will be attached to these rails.
  6. Panel Installation: The solar panels are then attached to the racking system using clamps or brackets. The panels are positioned to maximize sunlight exposure, typically facing south or at an optimal angle for the geographic location.
  7. Electrical Wiring: After the panels are secured, they are connected to the inverter and the home’s electrical system through a series of wiring. The wiring is carefully routed and secured to ensure it is safe and does not interfere with the roof’s integrity.
  8. Inspection and Testing: Once the installation is complete, the system is inspected and tested to ensure it is functioning correctly and safely. This includes checking the electrical connections and ensuring the panels are producing the expected amount of energy.

  These steps help ensure that the solar panels are securely attached to the roof and can withstand various weather conditions while providing efficient energy production.

• Does Pennsylvania provide enough sun to make solar panels worth it?

  Yes, Pennsylvania provides enough sunlight to make solar panels a worthwhile investment. Several factors contribute to the effectiveness of solar panels in the state:

  1. Solar Irradiance: Pennsylvania receives an average of about 4.2 to 4.6 peak sun hours per day, which is sufficient for generating significant amounts of solar energy. This level of solar irradiance is adequate to ensure that solar panels can produce a substantial amount of electricity, making them a viable option for homeowners​​.
  2. Electricity Rates: Pennsylvania has above-average electricity rates, which makes the savings from solar panels more substantial. Higher electricity costs mean that the savings from generating your own solar power will be greater, leading to a shorter payback period​.
  3. Net Metering and Incentives: Pennsylvania offers strong net metering policies, allowing homeowners to earn credits for excess electricity produced by their solar panels. This policy helps maximize the financial benefits of solar energy. Additionally, incentives like the Solar Renewable Energy Credits (SRECs) and the federal Investment Tax Credit (ITC) can significantly reduce the initial cost of solar panel installations​.
  4. Environmental Benefits: Using solar energy reduces reliance on fossil fuels, lowering greenhouse gas emissions and contributing to a cleaner environment. This benefit, combined with the financial incentives, makes solar energy an attractive option for many Pennsylvania homeowners​​.

  Overall, the combination of adequate sunlight, high electricity rates, strong net metering policies, and financial incentives makes solar panels a worthwhile investment in Pennsylvania.

• How much energy does a typical Pennsylvania household consume?

  The average Pennsylvania household consumes about 12,312 kWh of electricity per year, which equates to approximately 1,026 kWh per month. This level of consumption supports the viability of solar panel installations as it provides substantial potential savings on electricity bills​.

• Are permits required for solar panel installation in Pennsylvania?

  Yes, permits are required for solar panel installation in Pennsylvania. The permitting process ensures that the installation meets local building codes and safety standards. Here are some key points regarding permits for solar panel installations in Pennsylvania:

  1. Building Permits: Homeowners must obtain a building permit from their local municipality before installing solar panels. The permit ensures that the installation complies with local building codes and zoning regulations.
  2. Electrical Permits: An electrical permit is also required to ensure that the solar panel system’s electrical components are safely integrated into the home’s electrical system. This permit typically involves an inspection by a licensed electrician.
  3. Utility Interconnection Approval: In addition to local permits, homeowners need approval from their utility company to connect the solar panel system to the grid. This process involves submitting an interconnection application and ensuring the system complies with utility standards.
  4. Inspection: After installation, the system must be inspected by local authorities to verify that it meets all safety and code requirements. This inspection is part of the permitting process and is necessary before the system can be activated.

  Specific Requirements by Municipality: The specific permitting requirements and processes can vary by municipality, so it is essential to check with local authorities for detailed information.
