Residential, commercial, and battery storage solutions designed for Chester County’s energy market.
Over 60 percent of Chester County’s housing stock consists of detached single-family homes, with a median build year of 1982. These homes typically feature strong roof exposure and support systems sized to offset most or all of a household’s PECO bill.
Chester County is home to a significant corporate presence, with major employers and business parks concentrated along the Route 202 corridor, in Great Valley, Exton, Malvern, and West Chester. Business owners can take advantage of the federal Investment Tax Credit, available through July 4, 2026, to reduce system costs significantly.
Chester County homeowners increasingly pair solar with battery storage to maintain power during PECO outages and maximize the value of every kilowatt-hour their system produces. If your roof needs replacement before solar can be installed, Sunwise offers a bundled roof-and-solar installation that saves time and money compared to handling them separately.
PECO serves most of Chester County, and residential customers are paying more than ever, now averaging around 20 cents per kWh as of early 2026, up more than 20 percent from early 2025 levels. Further rate adjustments driven by PJM capacity cost increases are expected through the end of 2026. Chester County homes are larger than the state average, with typical monthly usage between 900 and 1,400 kWh, which means utility bills here are among the highest in southeastern Pennsylvania. For business owners, the federal Investment Tax Credit remains available through July 4, 2026.
A Sunwise Energy Specialist evaluates your home’s energy usage, roof condition, and sun exposure. We review your PECO billing history to design a system sized to your actual consumption and walk you through projected savings, SREC income, and net metering credits.
We create a custom system design and handle all permitting. Chester County’s 73 municipalities each manage their own building and electrical permits, and timelines vary between West Chester, Tredyffrin, East Whiteland, Westtown, and other jurisdictions. Sunwise coordinates every submission and inspection so you don’t have to.
Our in-house crews handle the full installation, typically completing residential systems in under a day on roof. Every system uses premium panels and microinverters for maximum long-term production and reliability. Our team handles all electrical work, racking, and wiring to meet Pennsylvania building and electrical code.
Sunwise coordinates your utility interconnection application and meter swap with PECO. Once PECO grants Permission to Operate, your system goes live, producing power, earning net metering credits, and generating SRECs. We activate your monitoring so you can track production in real time.

The county seat and most populous borough, West Chester features a mix of historic homes, Victorian-era properties, and newer townhome developments. Many homes in the borough have strong roof exposure and support systems that significantly reduce PECO bills.
The county's most populous municipality, home to communities like Paoli, Berwyn, and Devon along the Main Line. Larger homes with higher energy consumption make for strong solar economics, though mature tree canopy requires careful shade analysis.
Another Main Line community including parts of Devon, Berwyn, and Daylesford. Established neighborhoods with larger lots and higher property values support premium solar installations with fast payback timelines.
Home to the Great Valley Corporate Center and a rapidly growing residential base. A mix of newer construction and established developments, many with excellent south-facing roof exposure.
Malvern's walkable downtown and Willistown's rural-suburban character provide a range of housing from borough rowhouses to larger estate properties. Both areas are well suited for residential solar.
The Exton area and Downingtown borough sit at a key crossroads of Chester County's growth, with a mix of new residential construction, retail centers, and industrial parks. Both residential and commercial solar opportunities are strong.
A revitalized borough along the Schuylkill River with a mix of older rowhomes, renovated colonials, and new townhome construction. Compact roof areas benefit from high-efficiency panel layouts.
Chester County's only city, with a mix of rowhomes, detached single-family homes, and commercial properties. Solar reduces energy costs for homeowners and business owners across Coatesville's diverse building stock.
Known as the Mushroom Capital of the World, Kennett Square and surrounding townships like Kennett, East Marlborough, and New Garden feature a mix of suburban developments, agricultural properties, and commercial facilities with strong solar potential.
The commercial and retail heart of the county, anchored by the Route 30 and Route 202 corridors. Large suburban homes, shopping centers, and corporate offices all benefit from solar.
More rural character with larger properties, fewer shading constraints, and excellent solar exposure. Properties in the far western portion of the county may be served by a utility other than PECO. Sunwise will confirm your provider during your consultation.
We also provide solar installation throughout the broader Pennsylvania service area. View all PA locations → https://sunwiseusa.com/locations/pa/
Solar cost in Chester County depends on your home’s energy usage, roof size and condition, system capacity, and whether you add battery storage. Pennsylvania SRECs ($25-$40/credit), PECO net metering, and $0-down financing options reduce the effective cost significantly. Commercial property owners can also take advantage of the federal Investment Tax Credit through July 4, 2026.

Yes, PECO supports net metering at the full retail rate for residential and commercial solar customers throughout Chester County. When your system produces more electricity than you use, the excess is sent to the grid and you receive credits on your PECO bill. Credits roll forward month to month and are reconciled annually at the price-to-compare rate.
Chester County homeowners can earn Pennsylvania SRECs ($25-$40 per credit for every MWh produced) and receive retail-rate net metering from PECO for energy sent back to the grid. Pennsylvania does not offer property tax or sales tax exemptions for solar, and PA charges 6% sales tax on solar equipment. However, the combination of SRECs, net metering, and long-term PECO bill savings makes solar a strong financial investment. Business owners can also claim the federal Investment Tax Credit through July 4, 2026.
Solar permits in Chester County are managed at the municipal level, with each of the county’s 73 municipalities handling its own building and electrical permits independently. Requirements and timelines vary between West Chester, Tredyffrin, East Whiteland, Westtown, and other townships and boroughs. Sunwise handles all permit applications, inspections, and coordination with local building departments on your behalf.
Yes, solar is a strong financial decision for PECO customers in Chester County paying approximately 20¢/kWh all-in as of early 2026. PECO rates have risen more than 20 percent since early 2025, driven by PJM capacity cost increases, and further rate adjustments are expected through the end of 2026. Solar locks in a fixed energy cost and protects you from continued rate increases. Pennsylvania does not offer property tax or sales tax exemptions for solar, but SRECs and PECO net metering create strong long-term value.
Yes, Chester County has a significant commercial and corporate presence, with major employers and business parks concentrated along the Route 202 corridor, Great Valley Corporate Center, and the Exton and Malvern areas. Businesses can take advantage of the 30% federal Investment Tax Credit (available through July 4, 2026), accelerated depreciation, Pennsylvania SRECs, and net metering. Flat-roof office buildings, warehouses, and industrial facilities are ideal for commercial solar installations.
