Pennsylvania Net Metering Guide In 2025
If you’ve been considering solar panels for your Pennsylvania home, understanding how net metering works could be the key to maximizing your investment. This billing arrangement allows homeowners with solar systems to receive credits for excess electricity they send back to the grid, effectively turning your roof into a money-making asset.
With electricity rates rising across the state and enhanced policies making solar more attractive than ever, now is an excellent time to explore how this program can benefit Pennsylvania homeowners.
What Is Net Metering and How Does It Work?
Net metering is a billing mechanism that allows solar customers to receive credit for the electricity their system produces but doesn’t immediately use. When your solar panels generate more power than your home consumes, that excess energy flows back into the electric grid, and your utility company provides you with credits on your monthly bill.
Think of it as your electric meter running backward when your solar system overproduces. During sunny days, your system might generate surplus electricity that gets credited to your account. Later, when you need power at night or during cloudy periods, you can use those credits to offset your consumption charges.
The beauty of this arrangement lies in its simplicity: you’re essentially using the electric grid as a large battery, storing your excess solar production for later use making net metering worth it.
Pennsylvania's Net Metering Program: Current Rules and Benefits
The foundation for net metering in PA was established through the Alternative Energy Portfolio Standards Act (AEPS) of 2004, which directed the Public Utilities Commission to create rules requiring utilities to purchase renewable energy from customers.
Here are the key details every Pennsylvania homeowner should know:
System Size Limits
- Residential systems: Up to 50 kilowatts (kW)
- Commercial systems: Up to 3 megawatts (MW)
- Large systems: Up to 5 MW with special provisions
Eligible Utilities
All investor-owned utilities in Pennsylvania must offer net metering, including:
- PPL Electric Utilities
- PECO Energy Company
- Metropolitan Edison (Met-Ed)
- Pennsylvania Electric Company (Penelec)
- West Penn Power
- Duquesne Light Company
Compensation Structure
Pennsylvania offers some of the most favorable compensation in the country. Customers receive full retail rate credit for excess electricity sent to the grid. This means every kilowatt-hour you export is valued at the same rate you pay for grid electricity.
Recent Changes That Make Net Metering More Attractive
Several important developments have enhanced the value proposition for Pennsylvania solar customers:
The Hommrich Decision Impact
A 2021 Pennsylvania Supreme Court ruling in Hommrich v. Commonwealth significantly expanded net metering opportunities. The court determined that the PUC had overstepped its authority in limiting system sizes and output requirements. This decision opened the door for larger systems to participate in net metering programs.
Virtual Net Metering Expansion
New regulations now allow greater flexibility in system placement. Virtual net metering enables solar installations to be located away from your property, as long as they remain within the same utility service territory. Previously, systems had to be within a two-mile radius of the customer’s property.
Enhanced SREC Market
Pennsylvania’s Solar Renewable Energy Certificate (SREC) program provides additional income streams for system owners. Each megawatt-hour of solar production generates one SREC, which can be sold to utilities for additional revenue.
Financial Benefits: Real Numbers for Pennsylvania Homeowners
The financial case for solar with net metering has never been stronger in Pennsylvania. Here’s what homeowners can expect:
Rising Electricity Rates Create Bigger Savings
Pennsylvania electricity rates have increased significantly in 2025:
- PECO rates increased by 12.6%
- PPL customers see a 16% increase
- Met-Ed raised prices by approximately 8%
These rate increases make net metering credits more valuable, as each kilowatt-hour of solar production offsets higher utility costs.
Typical Savings by System Size
Based on current Pennsylvania electricity rates, homeowners can expect substantial annual savings:
- 5 kW system: Approximately $750 in annual savings
- 10 kW system: Around $1,500 in annual savings
- 15 kW system: Up to $2,250 in annual savings
These figures include both direct bill reductions and net metering credits for excess production.
Payback Period Improvements
With rising electricity rates and stable solar installation costs, most Pennsylvania homeowners now see payback periods of 6-8 years for their solar investments when including net metering benefits.
How to Get Started with Net Metering in Pennsylvania
The application process for net metering has been streamlined to encourage adoption:
Step 1: System Design and Permitting
Work with a qualified solar installer like Ethical Energy Solar to design a system that meets your energy needs and complies with local building codes. Your installer will handle most of the paperwork and permitting requirements.
Step 2: Interconnection Application
Submit an interconnection application to your utility company. The application type depends on your system size:
- Level 1: Systems ≤ 10 kW (simplified process, $100 fee)
- Level 2: Systems up to 2 MW ($250 + $1/kW fee)
- Level 3: More complex systems requiring detailed studies
Step 3: Utility Review and Approval
Your utility will review the application to ensure safe interconnection with their system. Processing times vary:
- Level 1 applications: Typically 30 days
- Level 2 applications: 35-45 days
- Complex systems may require several months
Step 4: Installation and Commissioning
Once approved, your installer can complete the system installation and arrange for final utility inspection and meter installation.
Maximizing Your Net Metering Benefits
To get the most value from net metering in PA:
Size Your System Appropriately
While you can technically install a system larger than your annual consumption, the optimal size typically matches 90-110% of your historical electricity usage. This ensures maximum benefit from net metering credits.
Consider Time-of-Use Patterns
Although Pennsylvania utilities don’t currently have widespread time-of-use rates, understanding when your system produces versus when you consume electricity can help optimize your savings.
Monitor System Performance
Regular monitoring ensures your system operates at peak efficiency, maximizing both electricity production and net metering credits.
Take Advantage of Additional Incentives
Combine net metering with other available incentives:
- Federal solar tax credit (30% through 2032)
- SREC sales for additional income
- Local rebates where available
Taking the Next Step
Net metering in PA represents one of the most powerful tools available for reducing electricity costs while supporting clean energy development. With rising utility rates, favorable policies, and decreasing solar costs, Pennsylvania homeowners have a unique opportunity to take control of their energy future.
The program’s full retail rate compensation, combined with additional Pennsylvania incentives like SRECs and federal tax credits, creates compelling economics for residential solar installations. Whether you’re motivated by cost savings, environmental benefits, or energy independence, net metering provides a clear path to achieving your goals.
