If you're considering solar in Pennsylvania, there's one policy you need to understand before anything else: net metering. It's not the sexiest topic, we know. But it's the single biggest reason solar makes financial sense for PA homeowners, and getting it wrong (or not understanding it) is where people get confused about their savings.
We've explained net metering in thousands of consultations, and we've gotten pretty good at making it click. Here's the straightforward version of how it works, how it affects your bill with Duquesne Light, Penelec, and other PA utilities, and why it's the linchpin of your solar investment.
Important: Individual prices and savings vary greatly. Dollar amounts in this article are illustrative examples and educational context, not promises of what you will pay or save. Only a written proposal after we assess your property reflects your specific project.
Net Metering in Plain English
When your solar panels produce more electricity than your home is using at that moment, the excess power flows back into the grid. Your electric meter tracks this. It literally runs backward during those periods. Your utility gives you a credit for every kilowatt-hour you send back, and that credit offsets electricity you pull from the grid later.
Think of it like a bank account for electricity. When the sun is shining and your panels are overproducing, you're making deposits. When it's nighttime or a cloudy day and you need more power than your panels provide, you're making withdrawals. At the end of the month, your utility looks at the net difference. Hence the name "net metering."
Here's the part that makes it really valuable: in Pennsylvania, those credits are at the full retail rate. If you pay $0.14/kWh for electricity, every kWh you send back is credited at that same $0.14. You're getting dollar-for-dollar value for your excess production. That's not the case everywhere. Some states credit at a lower wholesale rate, but PA gives you the full retail value.
Net metering effectively turns the entire electric grid into a free battery for your solar system. You store excess energy on the grid during the day and pull it back at night, all at a 1:1 exchange rate.
Why Net Metering Makes or Breaks Solar Economics
Without net metering, residential solar would be a much harder sell. Here's why: your solar panels produce the most electricity between about 10am and 3pm. But if you're a typical household, nobody's home during those hours. You're at work, the kids are at school, and your home is using maybe 1-2 kWh per hour while your panels are pumping out 5-7 kWh.
Without net metering, all that midday surplus would be wasted, or more accurately, you'd give it to the utility for free. You'd only save money during the hours your production and consumption overlap, which for many homes is maybe 30-40% of total production. The economics wouldn't pencil out for most homeowners.
With net metering, every single kilowatt-hour your system produces has value. It either powers your home directly or earns you a credit you can use later. That transforms solar from a partial solution into a near-complete one. In our experience, net metering is responsible for 50-60% of the total financial benefit of going solar.
Pennsylvania's Net Metering Law: What's Required
Pennsylvania's net metering rules aren't a voluntary program or a utility promotion that could disappear next quarter. They're state law, codified under the Alternative Energy Portfolio Standards Act of 2004 (Act 213). Every investor-owned utility in PA is required to offer net metering to residential customers.
Here are the key provisions that matter for homeowners:
- Systems up to 50 kW qualify (residential systems are typically 5-12 kW, so you're well within the limit
- Credits are calculated at the full retail rate, not wholesale
- Excess credits roll forward month to month for the full annual billing period
- At the end of the annual period, any remaining credits are compensated at the price-to-compare (wholesale generation) rate
- Your utility cannot charge you extra fees for being a net metering customer
- You have the right to net meter. Your utility cannot deny your application if you meet the requirements
That last point matters. We've occasionally had customers worry that their utility will fight them on solar. They can't. If your system meets interconnection standards (which your installer handles), the utility is legally obligated to connect you and provide net metering. Period.
How Net Metering Works with Duquesne Light
Duquesne Light serves about 600,000 customers in the greater Pittsburgh area, covering Allegheny and Beaver counties. If you're in Pittsburgh, the South Hills, Moon Township, Cranberry Township, or surrounding communities, this is your utility. Here's how net metering plays out on your Duquesne Light bill.
Monthly Billing
Each month, Duquesne Light looks at how much electricity you consumed from the grid minus how much you sent back. If you consumed more than you produced, you pay for the net amount. If you produced more than you consumed, the excess kWh become credits that appear on your bill and carry forward to the next month.
On your actual statement, you'll see a line item showing your net metering credits. During heavy production months (June and July, typically), that credit balance grows. During winter months, it shrinks as you draw against it. Your minimum bill will still include the customer charge (about $10.85/month) and any applicable distribution charges, even in months where your credits cover all supply costs.
Annual True-Up
Duquesne Light reconciles your account once per year, typically on your meter anniversary date (not a calendar year). If you still have credits remaining at the annual true-up, you don't get retail rate for them. Instead, Duquesne pays you at the "price to compare" rate, the wholesale generation rate, which has recently been in the $0.05-$0.07/kWh range.
So if you had 500 kWh of excess credits at your annual true-up, you'd get paid about $25-$35 for them rather than the $65-$75 they'd be worth at retail. That's why right-sizing your system matters. We'd rather design a system that slightly underproduces annually than one that wastes a lot of excess at the wholesale buyback rate.
With Duquesne Light, your net metering credits are most valuable when you use them yourself throughout the year. Excess credits at the annual true-up are only paid at wholesale rates, roughly 40-50% of what they were worth when you earned them. Right-sizing your system avoids leaving money on the table.
How Net Metering Works with Penelec and FirstEnergy
Penelec (Pennsylvania Electric Company) is part of the FirstEnergy family and serves a large swath of central and northern PA: Erie, State College, Altoona, and many rural areas. If you're outside the Pittsburgh metro but still in PA, there's a good chance you're a Penelec customer.
The mechanics are similar to Duquesne Light. Monthly credits roll forward, and your bill reflects net consumption. The main differences are in billing format and the specific rates applied. Penelec's customer charge is roughly $11/month, and their supply rates fluctuate quarterly based on their default service plan.
Credits and Billing Through FirstEnergy
Penelec bills through the FirstEnergy system, so your statement looks a bit different from Duquesne Light. Net metering credits are tracked separately from distribution charges. One thing to be aware of: if you're on a third-party electricity supplier instead of Penelec's default service, your net metering credits apply at your supplier's rate. Make sure you understand your supply arrangement before going solar. In most cases, switching to default service simplifies the net metering math.
Penelec also does an annual reconciliation of excess credits. Same deal as Duquesne Light: remaining credits are paid out at wholesale, not retail. The timing of the true-up varies by customer, so check your account or ask your installer to help identify your anniversary date.
Ohio Utilities: A Quick Comparison
Since we also serve Ohio homeowners, here's how net metering works across the state line. Ohio also has mandatory net metering for investor-owned utilities, including FirstEnergy Ohio (covering the Cleveland/Akron area) and AEP Ohio (covering Columbus and southern Ohio).
Ohio's net metering functions very similarly to PA's: credits at the full retail rate, monthly rollover, annual true-up at wholesale. The specifics of customer charges and rate structures differ by utility, but the core benefit is the same. If you're an Ohio homeowner, net metering makes your solar investment work the same way it does for PA customers.
The Seasonal Banking Effect: How Credits Work Across the Year
This is the part that really makes net metering powerful for our climate. In the Pittsburgh area, a typical solar system produces about 45-50% of its annual energy during May through August. But your electricity usage doesn't follow the same pattern. Especially if you have electric heat or a heat pump, winter usage can be just as high as summer.
Net metering smooths this out. Here's a simplified example for an 8kW system on a home using 850 kWh/month:
- June: You produce 1,200 kWh, use 750 kWh. Net: +450 kWh credited to your account.
- July: You produce 1,150 kWh, use 900 kWh (AC is working hard). Net: +250 kWh credited.
- August: You produce 1,050 kWh, use 850 kWh. Net: +200 kWh credited.
- December: You produce 450 kWh, use 950 kWh. Net: -500 kWh drawn from credits.
- January: You produce 400 kWh, use 1,000 kWh. Net: -600 kWh drawn from credits.
See the pattern? Summer surpluses build a credit cushion that winter deficits draw against. For a properly sized system, the math roughly balances over 12 months. You might end the year with a small credit surplus or a small net draw from the grid. Either way, you've dramatically reduced your annual electricity cost.
Net metering isn't just about saving money month by month. It's a seasonal storage mechanism. Summer credits fund winter usage. Without this banking effect, solar in northern climates like Pittsburgh would require expensive battery storage to capture the same value.
What Happens to Leftover Credits at Year-End
Let's say your system slightly overproduced for the year and you've got 300 kWh of credits sitting on your account at the annual true-up. In PA, your utility buys those remaining credits at the price-to-compare rate, the wholesale generation price. For Duquesne Light, that's been roughly $0.05-$0.07/kWh in recent years.
So those 300 kWh get you a check (or account credit) for about $15-$21. Compare that to the $42-$45 they'd have been worth at retail rates. That's a 50-65% haircut on the value of those excess credits.
This is exactly why we spend so much time right-sizing systems. Oversizing by 10% isn't a big deal; you'll lose a few dollars at the annual true-up, no big deal. But oversizing by 30-40% means you're consistently overproducing and losing value on those excess credits every year. We'd rather have your system cover 95% of your annual needs than 130%.
Can You Avoid the Annual True-Up Penalty?
There are a couple of strategies. First, size your system correctly. This is by far the most important factor, and it's something we handle during the design process. Second, if you're thinking about getting an electric vehicle, a heat pump, or adding other electrical loads, factor that future usage into your system size. Better to slightly oversize now than to come up short after you've increased your consumption.
Some homeowners also consider battery storage, which lets you use more of your own solar production directly (especially at night) rather than sending it to the grid. This can reduce your credit surplus, but the battery cost is significant and may not justify itself purely as a credit management tool. Batteries make more sense if you also want backup power.
Is Pennsylvania's Net Metering Policy at Risk?
This is the question we get from homeowners who've done their homework. They've read about states like Nevada and California rolling back net metering policies, and they want to know if PA could do the same. It's a smart concern, so here's our honest assessment.
Pennsylvania's net metering policy has been stable since Act 213 passed in 2004. There have been occasional rumblings from utility lobbyists about modifying the structure, but nothing has gained significant traction in the state legislature. PA's policy is moderate compared to some states (the annual true-up at wholesale already limits how much the utility "loses" on net metering), which may be why there's been less pressure to change it.
That said, we'd be lying if we told you it's guaranteed forever. Utility policy is political, and politics change. States that have weakened net metering, like California's NEM 3.0, typically grandfathered existing solar customers under the old rules for 15-20 years. So even if PA were to change its policy tomorrow, you'd likely be protected for the better part of your system's lifespan.
If PA ever changes its net metering rules, existing solar customers would almost certainly be grandfathered under current terms. Every state that's modified net metering has done this. But the longer you wait, the more you're betting on future policy. Going solar while the current rules are in place locks in those benefits for you.
Net Metering vs. Battery Storage: Do You Need Both?
We touched on this earlier, but it's worth addressing directly because we get this question a lot. Net metering and battery storage both solve the same basic problem: what to do with solar energy you produce but don't use immediately. They just go about it in different ways.
Net metering sends excess power to the grid and gives you credits. It's free (no additional hardware cost), gives you 1:1 value during the year, and works automatically. The downside: you don't have backup power during outages, and leftover credits at year-end are compensated at wholesale.
Battery storage keeps excess power in your home for later use. It provides backup during outages, reduces grid dependence, and lets you use 100% of your own production. The downside: batteries do add cost. The broader market runs $10,000-$15,000 per battery installed, though our installs typically come in at $8,000-$9,000 each, well below that average. Batteries have a limited lifespan (10-15 years), and the financial return depends on your specific usage patterns.
For most PA homeowners right now, net metering alone provides great economics. We recommend batteries for customers who either want outage protection or have specific usage patterns (like time-of-use rates) that make self-consumption more valuable. If net metering ever gets weakened in PA, batteries will become a more important part of the equation.
The Bottom Line: Net Metering Is Why Solar Works in PA
Strip away the SRECs and the environmental benefits, and net metering is still the single biggest reason solar makes financial sense in Pennsylvania. It's what turns a system that produces power during the day into one that effectively covers your electricity needs around the clock, all year long. With the federal tax credit gone for homeowners as of 2026, net metering carries even more of the load.
Your panels produce. The grid stores your excess. You use credits when you need them. It's an elegant system, and PA law guarantees your access to it. For a typical homeowner with a $150/month electric bill, net metering is responsible for turning a "maybe solar makes sense" situation into a "solar clearly makes sense" decision.
