Community Solar Programs in Pennsylvania

Community solar programs allow Pennsylvania residents and businesses to access solar-generated electricity without installing panels on their own property. This page covers how these programs are structured, which subscribers are eligible, how credits flow through utility bills, and where Pennsylvania's regulatory framework sets the boundaries. Understanding these mechanics matters because community solar fills a critical gap for renters, homeowners with shaded or structurally limited roofs, and low-to-moderate income households that cannot pursue rooftop solar installations.

Definition and scope

Community solar — also called "shared solar" or "solar gardens" — refers to a model in which a centrally located solar array generates electricity that is allocated among subscribing participants. Each subscriber receives a proportional credit on their utility bill corresponding to their share of the array's output, rather than receiving electricity directly from on-site panels.

In Pennsylvania, community solar does not yet operate under a single statewide mandate comparable to the frameworks in New York or Illinois. Instead, programs exist through voluntary utility pilots and third-party developer arrangements. The Pennsylvania Public Utility Commission (PUC) regulates investor-owned utilities and has authority over billing and tariff structures that affect how community solar credits are delivered. The Pennsylvania Alternative Energy Portfolio Standard (AEPS) — established under Act 213 of 2004 — classifies solar as a Tier I resource, which affects how solar renewable energy credits (SRECs) generated by community projects may be counted (Pennsylvania Alternative Energy Portfolio Standard).

Scope and coverage limitations: This page addresses community solar as it applies within Pennsylvania's jurisdiction under PUC oversight. Federal incentive structures such as the Investment Tax Credit (ITC) under 26 U.S.C. § 48 apply separately and are not administered by the PUC. Municipal utility customers (those served by publicly owned utilities rather than investor-owned utilities) are not covered by PUC retail tariff rules in the same way, and program availability differs. This page does not address community solar in neighboring states such as New Jersey or Maryland, which operate under distinct regulatory regimes.

How it works

A community solar project follows a structured lifecycle that differs from a standard rooftop installation in 4 key phases:

1. Project development and siting — A developer selects a location — often a ground-mounted array of 1 megawatt (MW) or larger — and secures interconnection approval from the relevant investor-owned utility. Pennsylvania's major utility territories (PECO, PPL, Met-Ed, and Duquesne Light) each maintain their own interconnection procedures under PUC jurisdiction. Details specific to each utility are covered at pages such as PECO Solar Interconnection and Policy and PPL Electric Solar Interconnection and Policy.

2. Subscriber enrollment — Households or businesses sign a subscription agreement for a defined capacity share, typically measured in kilowatts (kW). Subscription sizes commonly range from 1 kW to 25 kW for residential participants, though limits vary by developer and utility program.

3. Credit delivery — As the array generates electricity, output is metered at the project site. The utility allocates bill credits to each subscriber proportional to their share. This mechanism operates similarly to net metering but involves a remote facility. The mechanics of net metering in Pennsylvania are detailed at Net Metering in Pennsylvania.

4. Contract management — Subscriptions typically run 20 to 25 years, though some programs offer shorter terms or exit provisions. Subscribers generally do not own the panels and are not responsible for maintenance or permitting at the array site.

The generating facility itself must comply with all applicable permitting, electrical codes (National Electrical Code, NFPA 70), and utility interconnection standards — responsibilities that fall on the project developer, not individual subscribers.

Common scenarios

Renters and condo owners: Tenants who cannot modify their building's roof represent a primary target population for community solar. A renter in Philadelphia served by PECO can subscribe to an off-site array and receive credits directly on their PECO bill without any structural assessment of their dwelling. Roof assessment considerations that apply to owned properties are covered separately at Roof Assessment for Solar in Pennsylvania.

Low-to-moderate income (LMI) households: Some community solar developers and utility programs carve out discounted subscription rates for LMI participants. Pennsylvania's Act 129 energy efficiency framework administered by the PUC also intersects with affordability programs for qualifying households (Pennsylvania Act 129 and Solar Energy). Dedicated low-income solar resources are discussed at Solar for Low-Income Households in Pennsylvania.

Small businesses and nonprofits: Commercial subscribers can offset a portion of their electricity load through a community solar share. Nonprofits — which cannot directly monetize federal tax credits — sometimes find community solar subscriptions more accessible than owning a system. Nonprofit and Municipal Solar in Pennsylvania covers adjacent considerations.

Agricultural operations: Farms with high daytime electricity loads but complex roof geometries or priority land uses may subscribe to off-farm community solar rather than develop on-site arrays. Agricultural Solar in Pennsylvania addresses the on-site alternative.

Decision boundaries

Community solar is distinct from rooftop solar, ground-mounted ownership, and pure power purchase agreements (PPAs) in ways that affect financial outcomes and obligations:

SREC ownership is a critical distinction. Under most Pennsylvania community solar arrangements, the developer retains the SRECs generated by the array, which means subscribers do not receive the SREC market value on top of their bill credits. The Pennsylvania SREC Market page provides context on what that value represents for owners versus subscribers.

Subscribers evaluating a community solar contract should also examine whether the credit rate is fixed or indexed to the utility's retail rate, since a declining retail rate reduces the subscription's effective savings. The broader regulatory context for Pennsylvania solar energy systems — including PUC tariff structures — determines how these credits are calculated and reported.

Pennsylvania does not currently have a statutory community solar program with a defined MW capacity cap and subscription portability mandates, distinguishing it from states such as Minnesota (with its 100 MW program) and New York (with its 6 GW community distributed generation target under NY PSC Case 15-E-0082). Program availability in Pennsylvania therefore depends on individual utility willingness to approve tariff riders and interconnection for community solar projects. Monitoring developments at the PUC and through the Pennsylvania Solar Authority home resource provides the most current program landscape.
