Community Solar vs Rooftop Solar: Contracts and Credits

Community solar and rooftop solar differ in location, ownership, contracts, billing, and maintenance. Understand eligibility, REC ownership, and whether credits outweigh fees before committing.

Sources reviewed: 2026-10-19

Key takeaways

  • Community solar serves households that cannot host rooftop systems due to roof condition, shading, ownership status, or upfront cost barriers, but availability depends on utility service territory and program eligibility rules.
  • Rooftop solar offers four arrangements (owned, financed, leased, PPA) with different tax-credit eligibility, maintenance responsibility, and contract portability; community subscriptions separate utility credits from provider charges on different billing lines.
  • REC ownership and environmental claims belong only to the entity holding the certificate; many leases, PPAs, and some community subscriptions do not transfer RECs to the subscriber, limiting renewable energy claims.
  • A community subscription does not supply backup at the home. Rooftop backup requires an appropriate compatible and approved system; panel ownership alone does not establish outage capability.
  • Contract exit terms, escalation clauses, moving portability, and early termination fees vary widely; reading disclosure documents before signing and confirming state consumer protections is essential.

What Community Solar and Rooftop Solar Actually Are

Community solar and rooftop solar are both ways to access electricity generated from photovoltaic panels, but they differ fundamentally in where the hardware sits and how you receive its output. The U.S. Department of Energy defines community solar as any solar project or purchasing program, within a geographic area, in which the benefits of a solar project flow to multiple customers such as individuals, businesses, nonprofits, and other groups. In most cases, customers benefit from energy generated by solar panels at an off-site array rather than one mounted on their own property. Rooftop solar, by contrast, involves a PV system physically installed on your home, whether you own it outright, finance it with a loan, lease the equipment from a third party, or sign a power purchase agreement with a developer who owns the panels.

The distinction matters because the two paths create different contractual relationships, different parties responsible for hardware, and different answers to questions about who owns the environmental attributes of the electricity produced. According to the DOE's homeowner guidance, your options when going solar include buying a system, leasing a system, or signing an agreement to buy solar power, and before you agree to anything you should know what you are getting. That same principle applies to community solar subscriptions, which add a further layer because the generating asset is not on your property at all. Understanding the basic mechanics of each model is the necessary starting point before comparing contracts, credits, and obligations.

Who Can Access Each Model and Why Eligibility Varies

Roughly half of U.S. households and businesses face barriers to hosting rooftop solar, according to analysis cited by the National Renewable Energy Laboratory and referenced by the DOE. Those barriers include not owning the home, having a roof whose age, shading, pitch, or structural condition does not support a PV system, or facing upfront costs that are out of reach. Community solar was developed specifically to serve those households. The DOE's homeowner guide notes that if a solar professional determines your roof is not suitable for solar, or you do not own your home, you can still benefit from solar energy through community solar, which allows multiple people to benefit from a single shared solar array.

That access objective does not mean every interested person automatically qualifies for every program. Eligibility for a community solar subscription typically depends on your utility service territory, because the bill credit mechanism requires your retail electric account and the project to be served by the same utility. Some programs restrict enrollment to customers of a specific investor-owned utility, municipal utility, or cooperative. Others have income thresholds, waitlists, or capacity caps. States with enabling legislation tend to have more projects and broader availability, but program structures differ considerably from state to state. Before assuming a subscription is available to you, check with your local utility or the program provider directly. For rooftop solar, eligibility hinges on your roof's physical suitability, homeownership status, and whether your utility's interconnection rules allow a system of the size you need.

Subscription and Ownership Structures Compared

Community solar participants typically subscribe to a share of an off-site array's output, paying a monthly subscription fee to the project provider. In some programs, participants may hold a partial ownership interest rather than a subscription, but the subscription model is more common. Either way, the local utility pays the project for the energy it generates, and each subscriber receives a portion of that dollar value as a credit applied to their monthly electric bill. The provider separately charges the subscriber for the subscription itself, so two line items appear: the utility credit and the provider charge.

Rooftop solar presents four distinct arrangements. Buying a system outright means you own the hardware and bear maintenance responsibility. A solar loan finances ownership while spreading payments over time. A lease has a third-party company install the system on your roof, and you pay a fixed monthly fee to use it. A power purchase agreement has a developer own the panels on your roof while you pay for the electricity they produce at a rate set in the contract. The FTC notes that with a lease or PPA, you do not own the system. Ownership can affect maintenance and transfer responsibilities, but the actual agreements control those obligations. No tax eligibility is inferred here. These structural differences carry consequences that extend well beyond the monthly charge.

Community Solar vs Rooftop Solar: Generation to Bill Credit

  1. Off-Site Generation (Community): Solar array located at central project site; provider develops and operates the facility; subscription fee charged by provider
  2. On-Property Generation (Rooftop): PV panels mounted on home; owned outright, financed with loan, leased from third party, or subject to PPA with developer
  3. Community Credit Applied: Utility pays project for generation; subscriber receives dollar credit on monthly electric bill; provider invoice arrives separately
  4. Rooftop Ownership Model: System owner receives utility credit if grid-tied; maintains equipment or pays third-party owner lease/PPA fee
  5. Rooftop Third-Party Model: Developer or lease company owns hardware and bears maintenance; subscriber or leaseholder pays monthly fee; no REC or tax-credit transfer unless contract specifies
Diagram shows two parallel paths: community solar subscription (off-site generation, provider charges separately, utility credits separately) and rooftop solar ownership (on-property generation, owner or financer maintains, or third-party manages under lease/PPA). Boundaries: rooftop systems shown as grid-tied without storage; community credits assume same-utility alignment. No tariff or settlement calculations included.

How the Utility Credit and Provider Bill Interact

In a community solar subscription, the credit and the charge appear as separate items and may not arrive on exactly the same billing cycle. The utility applies a credit to your electric bill based on your share of the project's generation, while the provider sends a separate invoice or applies a separate line item for the subscription fee. The two amounts are not guaranteed to be equal, and neither figure represents your complete utility bill, which still includes fixed utility charges such as delivery and administrative fees regardless of how much solar generation you use.

A straightforward hypothetical illustrates how these two items interact (hypothetical example with assumed values only, not a market offer, actual program, or whole-bill comparison): assume a subscriber's share of generation in a given month produces a $100 utility credit, and the provider charges $90 for the subscription. The net result of those two items alone is a $10 reduction. If the provider charge is instead $105 with the same $100 credit, the net result of those two items is a $5 additional cost. Nothing about this example implies a guaranteed discount, a typical market rate, or a whole-bill savings figure, all of which depend on variables including your utility's credit rate, the provider's pricing methodology, your usage, and whether billing periods align. The DOE notes that the credit is typically applied directly to a subscriber's monthly electric bill, but timing and credit rate details vary by program, so reading the subscription disclosure documents is essential before signing.

Contract Terms: Cancellation, Moving, and Escalation

Both community solar subscriptions and rooftop solar contracts can run for extended terms, and the consequences of ending early or moving differ meaningfully between models. The FTC advises consumers reviewing rooftop solar leases and PPAs to check whether there are early termination fees or other charges if you want to end the contract early, what you must do if you plan to sell your house, and whether the buyer will have to meet credit requirements or pay fees before taking over the contract. Some lease and PPA contracts are difficult and expensive to exit before the term ends. A rooftop solar loan tied to the home itself may complicate refinancing or sale in a different way depending on how the lien is structured.

Community solar subscriptions vary considerably in their exit terms. The DOE identifies no exit fees, termination fees, or sign-up fees as a best practice in consumer protection, but not all programs meet that standard. Some programs have short cancellation windows of thirty to sixty days, while others impose fees or require you to find a replacement subscriber. Moving is a particular complication: if you relocate outside the utility's service territory, you typically cannot take the subscription with you, and whether you can cancel without penalty depends on the contract language. Escalation clauses are another document check item for both model types. A rooftop lease or PPA may state that monthly payments can increase over time at a defined rate, and some community solar subscription agreements include similar escalators. Read the rate-change language carefully and ask the provider to show you projected costs under the escalation formula before signing.

Renewable Energy Certificate Ownership and Environmental Claims

A renewable energy certificate, or REC, is a document that proves a system generated a certain amount of renewable energy. The FTC explains that if you buy a rooftop system, you might be able to get RECs related to the electricity your system produces, and you might be able to sell or get credit for them. However, the FTC also warns that if your home business has solar panels and sells away all its RECs, it loses the right to tell customers it is using renewable energy. The same principle applies to any solar arrangement: the entity that holds the RECs is the entity that can make a legitimate environmental claim about using renewable electricity.

For community solar subscriptions and rooftop leases or PPAs, REC ownership is not automatically transferred to the subscriber or host customer. The FTC is explicit that when you lease a system or have a PPA, you cannot claim RECs, because those attributes go to the system's owner. Community solar subscription contracts vary on this point, and some programs do pass REC rights to subscribers while others retain them for the project developer or utility. Before signing any agreement, locate the REC language in the contract and determine whether the subscription or lease conveys the environmental attribute or only the energy credit. If making a renewable energy claim matters to you, confirming REC ownership in writing is a necessary document check, not an optional detail.

Maintenance Responsibilities and the Absence of On-Site Backup

One practical difference between community solar and rooftop solar concerns who is responsible for keeping the generating equipment working. In a community solar subscription, the project developer or operator handles all operations and maintenance on the off-site array. You have no hardware on your property to maintain, insure for physical damage, or coordinate repairs on. That simplicity is one reason the model appeals to renters, people with complex rooftops, and those who prefer not to manage equipment. With a rooftop solar lease or PPA, the third-party owner typically remains responsible for maintaining and repairing the panels, as the FTC notes, but you may need to notify the company before undertaking any roof work that requires accessing the panels. If you own your system outright or finance it, maintenance responsibility falls entirely to you.

A community subscription is not an on-site backup supply. Its credits do not keep electricity flowing to your home during a grid outage. Rooftop ownership also does not, by itself, establish backup capability: a conventional grid-connected array normally stops supplying power when the grid is unavailable unless an appropriate approved backup configuration is present. Ask for the actual compatible equipment, operating limits and approval requirements if resilience matters. Storage may be part of that design, but a subscription, panel count or ownership contract is not proof of outage operation. Keep any backup proposal separate from the community-versus-rooftop billing comparison.

Making the Decision: Document Checks and Next Steps

Choosing between community solar and rooftop solar requires matching your specific situation to the characteristics of each model rather than assuming one is universally better. Start by confirming whether your address is in a utility territory where community solar subscriptions are available, since the credit mechanism requires alignment between your retail account and the project's interconnection point. Then assess your roof's physical condition. The DOE's homeowner guide notes that panels typically perform best on south-facing roofs with a slope between 15 and 40 degrees, and that age and shading matter significantly. If a professional assessment concludes your roof needs replacement before solar installation, that affects the timeline and cost structure for rooftop options.

For any agreement you are considering, the FTC recommends getting bids in writing from multiple providers, reviewing contract language on duration, payment escalation, early termination, REC ownership, and what happens at sale or move, and never signing under pressure. The DOE's community solar consumer protection guidance identifies disclosure documents provided upfront in plain language as a baseline expectation. For community solar programs specifically, check whether your state has enabling legislation and what consumer protections apply in your jurisdiction, because program structures are not uniform across states or utilities. The DOE's program hub describes the access goals of the National Community Solar Partnership and the range of program models, but qualifying for access objectives does not guarantee a specific savings outcome for any individual subscriber. Use the tools and guidance from federal agencies as a framework, then verify specific terms with your utility, the project provider, and if applicable a qualified solar installer.

Key Contract and Eligibility Checks Before Signing

  1. Confirm Eligibility: Community solar requires utility service-territory alignment and program availability; rooftop requires roof assessment and ownership status verification
  2. Review Contract Duration and Escalation: Check subscription or lease term length, whether fees can increase, and exact formula for rate changes; request projected costs over full term
  3. Examine Exit and Portability Terms: Community: cancellation windows, moving restrictions, relocation penalties; rooftop lease/PPA: early termination fees, home-sale transfer rules, new-owner credit requirements
  4. Locate REC Ownership and Environmental Claims Language: Identify which party holds renewable energy certificates; confirm whether you can make legitimate renewable electricity claims or if all credits go to developer
  5. Verify Maintenance and Backup Provisions: A community subscription does not supply backup at the home. Rooftop backup requires an appropriate compatible and approved system; panel ownership alone does not establish outage capability.

Frequently asked questions

Can I move my community solar subscription if I relocate?

Typically no. If you move outside your utility's service territory, the subscription ends because the bill-credit mechanism requires alignment between your retail account and the project. Some programs allow in-territory transfers; others may charge fees or require finding a replacement subscriber. Check your contract before signing and ask the provider about relocation policy for your specific program.

Do I own the renewable energy certificates if I have a rooftop lease or community solar subscription?

Usually no. The FTC explains that with a lease or PPA, the system owner holds the RECs. Many community subscriptions also retain RECs for the developer or utility. If you need renewable energy claims for marketing or environmental reporting, confirm REC ownership explicitly in the contract before signing. Some programs do transfer RECs; most do not.

What happens to my rooftop solar contract when I sell my home?

The buyer must typically take over the lease or PPA, and they may face credit requirements or transfer fees. A loan attached to the home complicates refinancing and sale differently. Ask the provider upfront whether the contract is assumable, what conditions the new owner must meet, and whether any fees apply. These details vary significantly by contract.

Why does community solar not provide backup power during a power outage?

A community subscription does not supply backup at the home. Rooftop backup requires an appropriate compatible and approved system; panel ownership alone does not establish outage capability.

Can I cancel my community solar subscription early without penalty?

Some programs have no exit fees, but others impose early termination charges or require you to find a replacement subscriber. Cancellation windows may be short (thirty to sixty days). The DOE identifies no fees as a best practice but notes program structures vary widely. Read your contract carefully before committing to understand the exit terms.

Are community solar subscriptions available everywhere, and who qualifies?

No. Availability depends on whether your utility offers a program and whether your address falls within the project's service area. Eligibility may involve utility account type, income thresholds, program capacity caps, or waitlists. The DOE's National Community Solar Partnership hub describes access objectives, but not every household qualifies for every program. Check with your utility directly.
