Groundswell’s SharePower: How Neighbors Help Fund No-Cost Community Solar

By PlugInSolarUS Editorial Team · Published 2026-11-06 · Updated November 6, 2026 · 9 min read

How Groundswell’s SharePower connects paying supporters with income-qualified no-cost solar credits, plus separate Maryland and DC eligibility checks.

Diverse neighbors gather beside a shared solar garden, with apartment buildings behind them, illustrating community support for solar access.

A renter does not need a sunny balcony to participate in solar. Through Groundswell’s SharePower model, a community solar project generates electricity away from the subscriber’s home, and the subscriber receives credits on a Pepco bill. No equipment needs to be installed at home. The opportunity is open to both renters and homeowners in the program’s published Maryland and Washington, DC, participation area—but a no-cost subscription is reserved for income-qualified households, not everyone who signs up.[1]

SharePower’s distinctive contribution is the connection between neighbors. Paying supporters help make no-cost subscriptions possible for qualifying households. Understanding those two roles is essential: supporting access to solar and enrolling to lower your own bill are not necessarily the same offer.

1. A nonprofit model built around access

Groundswell is the third nonprofit featured in Community Energy Spotlight, alongside the series’ Energy Outreach Colorado profile and Virginia Energy Efficiency Council profile. Here, the focus is a funding and subscriber-service model that lets households benefit from shared solar without buying home equipment.

The U.S. Department of Energy documents Groundswell’s role as developer and subscriber manager for a nonprofit-developed SharePower project at a Washington, DC, monastery. That project began operating in 2020; its profile relates to the 2022 Sunny Awards, rather than a new 2026 launch. It illustrates the model’s history, not current subscription availability or portfolio-wide savings.[2]

There is a timely community-energy connection. Groundswell’s October 23 announcement scheduled its Rural Renaissance Roadshow for November 4–6, 2026, in Decatur, Alabama. The agenda included energy affordability, resilience and a workshop for partners in its Save on Utilities Long-Term initiative. Those announced conversations highlight the organization’s wider interests; they do not establish event outcomes or a new SharePower enrollment opening.[3]

2. Paying supporters and no-cost beneficiaries have different offers

SharePower describes a straightforward arrangement for paying subscribers: they pay a flat subscription fee, receive part of that value back as a solar credit on their utility bill, and support no-cost subscriptions for low- and moderate-income neighbors through the remainder.[1]

That is an opportunity to support broader clean-energy access, but it should not be mistaken for a guaranteed personal discount. SharePower says most paying subscribers receive annual solar credits totaling approximately their subscription cost. Its public description does not justify promising that every paying household will come out ahead.[1]

Income-qualified beneficiaries have a different role. Groundswell calls these no-cost subscriptions Empowered subscriptions. A household approved for that offer receives the subscription’s bill-credit benefit without paying the supporter subscription fee. Qualification and an available subscription still matter; the word “no-cost” does not mean automatic enrollment or an electricity bill reduced to zero.[1]

For example, a household that wants to support its neighbors should compare the written supporter fee with expected annual credits and decide whether that contribution fits its budget. A household primarily seeking bill relief should ask specifically about income-qualified no-cost enrollment. Asking that question early avoids spending time on an offer designed for a different purpose.

3. Start with the Pepco account, not the roof

SharePower’s published FAQ identifies renters and homeowners in Maryland and Washington, DC, who pay a Pepco electricity bill as its participation audience. Living somewhere in Maryland is not enough by itself: the utility account and the subscription’s applicable service area need to match.[1]

For renters, this removes a familiar solar barrier. The program does not require a roof, balcony mounting space or an installation in the apartment. The shared project supplies the generation associated with the subscription; the household receives a utility-bill credit.[1]

A useful first step is to find a recent electricity bill and confirm the utility, service address and account details. If electricity is included in rent or billed through the building rather than a household Pepco account, ask Groundswell how that arrangement affects participation before applying. Do not assume a landlord’s Pepco account can deliver credits directly to your household.

Maryland readers comparing other projects can use our Maryland community-solar enrollment guide. SharePower is one model to understand, not a substitute for checking project availability and written terms.

4. Keep Maryland qualification separate from DC Solar for All

Groundswell’s general SharePower page says Empowered subscriptions are available to income-qualified households. It does not provide a Maryland household-income table. Maryland applicants should ask Groundswell which qualification rules and documents apply to the specific no-cost subscription being offered.[1]

The District’s Solar for All community-solar pathway has its own official rules. The DC Department of Energy and Environment, or DOEE, lists household-size income limits effective June 1, 2026. For a four-person household, the published limit is $132,900. The page warns that the amounts may change, so confirm the current threshold when applying. This figure is a DC rule—not a Maryland SharePower threshold.[4]

DOEE also identifies qualifying benefit programs, including the Low Income Home Energy Assistance Program, known as LIHEAP, and the Supplemental Nutrition Assistance Program, or SNAP. Its list includes several other assistance programs and housing vouchers. Participation in a listed program establishes income qualification under the resident guidance, but applicants still need to complete enrollment and meet the applicable program requirements.[4]

A DC renter should therefore ask which pathway the application uses and how to document eligibility. A Maryland renter should request the Maryland offer’s requirements rather than copy the District’s checklist. The shared Pepco name does not make the programs interchangeable.

5. What to expect from credits, timing and capacity

SharePower says it typically takes about 90 days for credits to start appearing on a Pepco bill because of billing cycles. Its FAQ identifies the bill entry as a “CNM Credit,” meaning community net metering credit. If credits have not appeared after that period, Groundswell directs subscribers to customer service.[1]

DC Solar for All describes a different sequence. Enrollment requires the necessary documents and entry into Pepco’s billing system. After Pepco receives updated enrollment information, DOEE anticipates credits within 60 days, while warning that processing issues can affect timing. These are different milestones, not competing promises that every application will produce credits by a fixed deadline.[5]

Availability also matters. Under DC’s terms, fully subscribed projects can mean assignment to the next available subscription allotment. Approval of eligibility does not guarantee immediate project capacity.[5]

Once credits begin, expect variation. SharePower says credits are typically larger in summer than winter. DC’s terms explain that actual production, subscription allocation and the applicable credit rate affect the value, and they do not guarantee a particular savings amount.[1] [5]

For household budgeting, that means keeping the remaining Pepco balance in your payment plan. A no-cost subscription is useful bill relief, not a reason to stop paying the utility or assume each month will have the same credit.

6. Ask a few specific questions before enrolling

The most useful enrollment conversation is about the actual offer available to your household. Ask whether it is a paid supporter subscription, a no-cost Empowered subscription or enrollment through DC Solar for All. Then request the applicable agreement before deciding.

For a paid offer, confirm the subscription fee, how it is billed and how projected credits compare over a full year. For a no-cost offer, confirm the income documents, whether capacity is available and what happens while waiting. In either case, ask who will help if the first credits are delayed and how to keep account information current.

Households receiving rental assistance should also check how the particular credit is treated in their housing arrangement. Our HUD-assisted renter community-solar guide covers questions about rent, utility allowances and billing. A program’s no-cost label alone does not resolve those separate issues.

Keep a copy of the agreement and enrollment confirmation. They give you a clear starting point if a later bill differs from what you expected.

7. Moving and cancellation depend on your subscription

SharePower’s general FAQ says a subscription can move with a subscriber to another address where they pay a Pepco bill in Maryland or DC. Subscribers should tell Groundswell’s customer-service team their moving plans and new address.[1]

Do not extend that general statement to DC Solar for All. The District’s terms say its subscription ends if the household moves out of DC. They also require address and Pepco account-number updates, continued eligibility and notification to DOEE if income becomes too high. The subscription cannot be assigned to another person or household.[5]

For example, a DC Solar for All participant moving to Maryland should contact DOEE about ending or updating the existing arrangement and separately ask Groundswell about Maryland options. A new Pepco account alone does not preserve District eligibility.

SharePower says subscriptions can be canceled without a penalty, but fees already paid are not refundable. DC Solar for All also allows termination without an early-exit penalty under its own terms.[1] [5] Before moving or canceling, ask when the change will be processed and how any final credits or paid fees will be handled.

8. Choose the next step that matches your energy goal

If your goal is bill relief without home equipment, start with SharePower eligibility and the written subscription offer. You do not need to shop for panels to participate. Groundswell lists customer-service help at customerservice@groundswell.org and 202-505-3051; DC residents can also reach DOEE’s Solar for All team at solarforall@dc.gov or 202-299-5271.[1] [4]

If you are separately considering equipment for your own home, start with our Plug-In Solar 101 guide. Check your space, property permissions, electrical requirements and state and utility rules before comparing products. That readiness process is separate from community-solar enrollment.

A home setup readiness check can help organize those questions, and the Product Finder can help compare equipment once the site is suitable. Neither step is required for SharePower: its subscription does not require a panel purchase.

A SharePower bill credit does not provide outage backup. Readers seeking that outcome should first distinguish bill savings from backup in What “Energy Independence” Means at Home. Choosing the desired outcome first helps avoid buying equipment—or selecting a subscription—for a job it does not do.

A practical way to share solar access

Groundswell’s SharePower offers two meaningful ways to participate: support neighbors through a paid subscription or seek income-qualified no-cost bill credits. Start with a recent Pepco bill, identify the correct Maryland or DC pathway, and ask for current availability and written terms. Those checks turn an appealing idea into an informed household decision.
