Lancaster County has the lowest solar installation costs in Pennsylvania thanks to rural labor rates, large rooftops, and ground-mount availability. Met-Ed territory at $0.19/kWh with stable net metering and good central PA irradiance. Larger systems and agricultural solar push per-watt costs even lower.

2026 Reality: The federal 25D solar ITC expired for homeowners. All Lancaster County costs reflect $0 federal credit. Farm solar may qualify for Section 48 commercial ITC. Details
A typical 14 kW system in Lancaster County costs $40,600 before taxes ($2.90/W avg). After 6% PA sales tax, total is $43,036. Annual net metering savings of $3,059 plus SREC income of $451/year yield a payback of 14.2 years. Lancaster is the best value in PA for solar.

Lancaster County is the most productive non-irrigated farming county in the US. Agricultural solar has unique advantages here: large barn roofs, open land for ground mounts, and high daytime electricity usage from farm operations.
Large south-facing barn roofs (2,000-5,000 sq ft) can accommodate 15-30+ kW systems
Metal standing-seam roofs allow clamp-on mounting with zero penetrations
Structural assessment is critical for older barns; many post-1960 barns are adequate
Barn solar offsets daytime loads: milking equipment, fans, refrigeration, lighting
SRECs generated by the system provide additional farm income ($500-$1,000+/yr for larger systems)
Ground-mount systems on unused farmland eliminate roof constraints and structural concerns
Optimal tilt and orientation produces 5-10% more energy than average rooftop installations
Cost premium of $0.10-$0.20/W over rooftop for racking and trenching (partially offset by easier installation)
Agricultural zones typically have relaxed setback requirements for ground-mount arrays
Can be sized to any capacity: 10 kW for a homestead or 50+ kW for a full farm operation
Dual-use agrivoltaics (panels over grazing or shade crops) is emerging in Lancaster County
Farm solar systems used for agricultural business operations may qualify for the Section 48/48E commercial Investment Tax Credit. This is the one federal incentive still available in PA for solar.

Solar adds to assessed value. Some boroughs may assess differently.
Lancaster County spans urban, suburban, and deeply rural areas, each with different solar potential and installation characteristics.
Urban, row houses, historic core
Lancaster city has a mix of row houses and single-family homes with typical 800-1,200 sq ft roofs
Historic downtown (Gallery Row area) may require additional review for exterior modifications
Compact row house roofs support 5-8 kW systems; south-facing is ideal
Urban installer availability keeps pricing competitive and scheduling fast
City permitting through Lancaster L&I, typically 2-3 weeks for standard residential
Typical System
5-8 kW
Cost Range
$14,500-$23,200
Permitting
2-3 weeks (Lancaster L&I)
Single-family homes, newer construction
Newer suburban construction (1980s-2020s) with 200-amp panels and south-facing roof designs
Larger roof areas of 1,500-2,500 sq ft accommodate 10-15 kW systems easily
Well-maintained homes with straightforward installations and minimal complications
Lower tree coverage in subdivisions compared to rural areas provides consistent sun exposure
Township permitting is efficient and solar-friendly in most Lancaster County municipalities
Typical System
10-15 kW
Cost Range
$29,000-$43,500
Permitting
2-3 weeks (township)
Farmhouses, barn roofs, open land
Large barn roofs (2,000-5,000 sq ft) are ideal for agricultural solar installations of 15-30+ kW
Ground-mount systems on unused farmland eliminate roof constraints entirely
Lower labor costs and easy site access reduce per-watt installation prices
Agricultural operations have high daytime electricity usage (fans, milking, refrigeration) that aligns well with solar production
Setback requirements are more relaxed in agricultural zones, allowing larger ground arrays
Typical System
12-30+ kW
Cost Range
$34,800-$87,000+
Permitting
2-3 weeks (township, usually straightforward)
Off-grid and hybrid solar applications
Some Amish communities use solar for specific purposes: battery charging, water heating, barn lighting
Off-grid solar systems with battery storage serve farms not connected to the grid
Hybrid systems charge batteries for lighting and small appliances without grid interconnection
No net metering participation (off-grid), so economics are based on avoided generator fuel costs
Installations must respect community norms and are typically rooftop-only on non-residential structures
Typical System
1-5 kW (off-grid)
Cost Range
$5,000-$20,000 (with batteries)
Permitting
Varies; off-grid may not require utility interconnection
Small towns, residential neighborhoods
Charming small-town homes with a mix of historic and modern construction
Lititz has been named a top small town in PA, with strong community solar interest
Moderate lot sizes with generally good sun exposure away from the town centers
Northern Lancaster County has slightly lower property values, reducing the property tax impact
Local installer networks serve these communities with competitive pricing
Typical System
8-12 kW
Cost Range
$23,200-$34,800
Permitting
2-3 weeks (borough/township)
Lancaster County's lower system costs make cash purchase more accessible, but PPA remains attractive for those who want $0 upfront with the financing company capturing the ITC.
Best for: Homeowners who can afford upfront cost and want maximum long-term savings
Best for: Homeowners who want ownership benefits without large upfront payment
Best for: Most PA homeowners in 2026 — MORE attractive post-ITC because the financing company claims the 30% Section 48 ITC and passes savings as a lower rate
Best for: Homeowners who want predictable monthly costs with no maintenance responsibility
Lancaster County has the lowest solar installation costs in the PA metro areas at $2.70-$3.10 per watt, averaging about $2.90/W. For a typical 14 kW system, the total cost is approximately $40,600 before the 6% PA sales tax ($2,436), for an all-in cost of about $43,036. Rural installations with large roof areas or ground mounts can be even lower on a per-watt basis.
Lancaster County has the lowest per-watt solar costs in PA for several reasons: (1) lower labor costs than Philadelphia or Pittsburgh, (2) large roof areas and ground-mount availability reduce per-watt installation overhead, (3) easy site access in rural and suburban areas reduces crew time, (4) a competitive installer market along the Route 30 corridor, and (5) simpler permitting compared to large cities.
Yes, ground-mount solar is very popular in rural Lancaster County. Ground-mount systems can be any size (typically 10-50 kW for residential/farm use) and can be optimally tilted and oriented for maximum production. They cost about $0.10-$0.20 more per watt than rooftop due to racking and trenching, but they avoid roof penetrations and can be placed for optimal sun exposure. Agricultural zones typically have relaxed setback requirements.
Yes, some Amish and Plain communities in Lancaster County use solar for specific applications, typically off-grid. Common uses include battery charging for lighting, water heating, and powering barn equipment. These are usually small systems (1-5 kW) paired with battery banks. Off-grid solar avoids the religious concerns about grid connection while providing practical electricity for farming operations.
Lancaster County is served by Met-Ed (a FirstEnergy company) with a retail rate of about $0.19/kWh. Met-Ed offers 1:1 full retail net metering for systems up to 50 kW, with annual true-up at the PTC rate of $0.119/kWh. Unlike PPL, Met-Ed has no proposed changes to its net metering policy.
Lancaster County solar systems have an approximate 11-year payback period for cash purchases. Despite having the lowest costs in PA, the payback is similar to Allentown because Met-Ed has a lower rate ($0.19/kWh vs PPL $0.21/kWh). However, 25-year savings are strong due to low system costs and good central PA irradiance (1,150 kWh/kW/year).
Farm solar systems generate PA SRECs just like residential systems. A 14 kW system produces about 16.1 SRECs per year, worth $354-$564 annually at current market prices. Larger agricultural systems (20-50 kW) produce proportionally more SRECs. SRECs are registered through PJM-GATS and traded on platforms like SRECTrade. Farm operations can also explore Section 48 commercial ITC if the system is used for business purposes.
Farm solar systems used for agricultural business operations may qualify for the Section 48/48E commercial ITC (30% base rate) if the system is owned by a business entity and begins construction before July 4, 2026. This is separate from the expired residential 25D credit. Consult a tax professional to determine eligibility. Additional ITC adders for domestic content and energy communities may apply.
