Most of Dauphin County is PPL territory. Parts of the West Shore are Met-Ed. Both raised rates significantly — and a $15 billion AI data center is now loading up PPL’s grid 20 miles away in Carlisle. Select your utility below to see your specific rate record. Solar Harrisburg PA homeowners who lock in now pay a fixed rate regardless of what either utility charges next.

Every time PPL adjusts its supply rate, passes through PJM capacity costs, or wins a distribution rate case, Harrisburg PPL customers absorb another increase. Residential solar panels Harrisburg PPL homeowners install lock in a rate that doesn’t move with any of it. Solar energy Harrisburg PA means paying for what your panels produce — not whatever PPL decides to charge next.
Every time Met-Ed settles a rate case, resets the supply rate, or passes through what PJM charges for capacity, Harrisburg Met-Ed customers absorb another increase. Harrisburg solar services for Met-Ed customers lock in a rate that doesn’t move with any of it.
Pennsylvania Digital I (PAX) — a joint venture between Pennsylvania Data Center Partners and PowerHouse Data Centers — is building three hyperscale AI data center campuses on Country Club Road in Carlisle, 20 miles from Harrisburg. PPL Electric Utilities is connecting it directly to their transmission system.
The project was announced before President Trump at Carnegie Mellon in July 2025. The 450 MW substation was unanimously approved by Middlesex Township in March 2026, clearing the way for construction to begin. At 1.35 gigawatts — growing to 1.8 GW — PAX will be one of the largest AI compute facilities in the eastern United States.
More load on PPL’s transmission system means more infrastructure investment, more capacity costs, and more upward rate pressure — recovered through rate cases. Solar panel installation in Harrisburg PA lets you lock your rate before that demand is fully online.
Lock My Rate Now →Since 2016, Met-Ed has invested over $1 billion in grid upgrades across its Pennsylvania service territory under two rounds of its Long-Term Infrastructure Improvement Plan. In December 2024, the PUC approved LTIIP III — another $382 million over five years — continuing that cycle of infrastructure spending through 2029.
None of this is free. Every dollar of infrastructure investment gets recovered through rate cases. The January 2025 distribution rate increase — the first since 2016 — covered LTIIP costs and the $230 million bribery fine FirstEnergy was issued for bribing government officials. Future LTIIP III costs will come through the next rate case. On top of that, PJM capacity prices have surged, driving the supply rate resets that landed in June and December of 2025 and June 2026.
The pipeline is structured. Rate increases aren’t unpredictable surprises — they’re the predictable result of a utility spending billions on its grid and billing the ratepayer. Harrisburg solar services for Met-Ed customers let you lock your rate before the next round of that billing arrives.

A Solar Energy Consultant assesses your roof, its sun exposure, and your annual usage. They custom design a system for your home or tell you honestly if your home doesn’t qualify for solar.
The Solar Energy Consultant handles the interconnection application, net metering enrollment, and all permit paperwork with them, the township, and the HOA (if present).
After utility approval, installation is scheduled and final inspections are completed by them and the township. Plan for one to four additional months before your system goes live.
Home solar panels Harrisburg homeowners install are roof-mounted, permitted locally, and sized to your actual utility bill. The best solar panel companies in Harrisburg serve homeowners across both Dauphin and Cumberland Counties. Solar panel installation in Harrisburg PA and the surrounding townships follows the same process — utility interconnection, local permitting, and inspection. A qualified solar installer in Dauphin County or a solar installer in Harrisburg will know your specific township’s requirements. Solar panels Dauphin County homeowners install follow the same interconnection and permitting process whether you're on PPL or Met-Ed. Solar installers in Dauphin County who work across the region handle both routinely.
The solar panel cost Harrisburg PA homeowners pay upfront is zero. With a $0 down PPA, you pay only for the electricity the system produces — at a rate locked below what PPL or Met-Ed charges. No installation cost, no equipment cost, no maintenance cost. The 60-second quiz calculates your exact numbers based on your specific utility and bill.
Check the top of your monthly electric bill — the utility name is printed clearly. Most of Harrisburg City, Lower Paxton, Susquehanna Township, and Dauphin County are PPL Electric territory. Portions of Cumberland County’s West Shore — including parts of Mechanicsburg and Carlisle — are served by Met-Ed. If you’re in a border area and still unsure, your bill will tell you definitively.
When evaluating solar companies in Harrisburg, the best solar panel companies in Harrisburg are Pennsylvania-licensed, experienced with both PPL and Met-Ed interconnection requirements, and familiar with Dauphin and Cumberland County permitting. Look for a solar installer in Harrisburg who gives you a straight answer when solar doesn’t pencil out for your home — not just someone trying to close a deal. A 25-year equipment warranty at no cost to the homeowner is the standard to expect.
The $15 billion PAX data center campus in Carlisle will pull up to 1.35 gigawatts from PPL’s transmission system — equivalent to the output of a large nuclear power plant, added to the same grid your electricity travels through. PPL is already investing in transmission upgrades to support it. Those infrastructure costs are recovered through rate cases. The 450 MW substation was approved in March 2026 and construction is underway. Harrisburg solar services let you lock your rate before that demand is fully online.
Net metering measures the difference between electricity pulled from your utility’s grid and electricity your panels send back to it. During daylight hours, your panels generate electricity and your home uses what it needs first. Any surplus flows to the grid, and your utility credits your account at the full retail rate for every kilowatt-hour you send back. Those credits cover your needs at night and in the winter, when your panels produce less.
Pennsylvania’s residential net metering is currently intact. PPL, Met-Ed, and PECO are all required by the state’s Alternative Energy Portfolio Standards Act and PUC regulations to offer 1:1 net metering to residential customers. That means if you put $1 worth of energy onto the grid, you get $1 back.
Not every state works that way. In California, if you put $1 of energy onto the grid, you get only $0.25 back. In Arizona, only $0.50 back (and that rate steps down every September for new customers). West Virginia’s Mon Power and Potomac Edison customers get only $0.70 back. In Indiana, only $0.30 back. In Utah, only $0.50 back. In Michigan, only $0.50 back on average.
For now, we are not among them, but Pennsylvania utilities and their regulators have been fighting over net metering rules in court since at least 2016.
The 60-second quiz uses your actual PPL or Met-Ed rate to calculate exactly how much solar energy Harrisburg PA would save you — Year One and over 25 years. Free, no obligation, no pressure.
