Virtual net metering is the billing mechanism that allocates production credits to each subscriber’s account
Typical bill savings range from 5% to 20%, depending on the program structure and local electricity rates
The U.S. community solar pipeline exceeds 50 GW, with over 40 states and territories exploring or operating programs
Community solar opens access for renters, apartment dwellers, and properties with shaded or unsuitable roofs

What Is Community Solar?

Community solar (also called shared solar or solar gardens) is a model where a single solar installation — typically a ground-mounted or rooftop array ranging from 500 kW to 5 MW — serves multiple subscribers who each receive a portion of the energy produced. Subscribers sign up for a share of the project’s output and receive credits on their electricity bills proportional to their allocation. No panels are installed on the subscriber’s property.

This model solves a fundamental market access problem. Roughly 50% of U.S. households and businesses cannot install rooftop solar due to renting, roof condition, shading, structural limitations, or HOA restrictions. Community solar gives these customers a path to benefit from solar energy.

Community solar is the fastest-growing segment of distributed solar in the United States. It turns solar from a homeowner-only product into a universal option — any electricity customer with a utility bill can participate.

Types of Community Solar Programs

Community solar programs vary in structure, financing, and target audience. Here are the four primary models:

Most Common

Subscription Model

Subscribers pay a monthly fee or per-kWh rate for a share of the project’s output. No upfront cost. Credits appear on the utility bill, typically at a discount to the retail rate. Contracts run 12 to 25 years, with some month-to-month options.

Investor-Oriented

Ownership Model

Participants buy a specific number of panels or a kW share in the project. Higher upfront cost, but greater long-term savings and potential tax benefits. Ownership stakes are sometimes transferable if the subscriber moves within the same utility territory.

Utility-Led

Utility-Sponsored Programs

The utility owns and operates the solar facility, offering customers voluntary subscription options. Simpler enrollment process but typically lower savings — the utility retains a larger margin. Common in regulated markets with limited third-party access.

Equity-Focused

Low-Income Community Solar (LMI)

Programs specifically designed for low-to-moderate income households. Often subsidized through state incentives, federal grants, or carve-outs requiring a minimum LMI subscriber percentage (commonly 40-50%). Provides guaranteed bill savings with no credit check or upfront payment.

Community Solar vs. Rooftop Solar vs. Utility-Scale Solar

Understanding where community solar fits in the broader solar market helps designers, developers, and sales teams position the right solution for each customer.

Contract Length	1–25 years	20–25 year system life	10–25 year PPA
Portability	Transferable within utility territory	Tied to property	N/A

How Subscriber Savings Work

The financial value of community solar depends on the gap between what subscribers pay for their share and what they receive in bill credits.

Subscriber Savings Formula

Subscriber Savings = Allocated Production (kWh) x (Retail Rate - Subscription Rate)

For example, a subscriber allocated 500 kWh/month from a community solar project pays $0.12/kWh in subscription fees. Their utility retail rate is $0.15/kWh. Monthly savings: 500 x ($0.15 - $0.12) = $15/month, or $180/year. This represents a 20% discount on the solar portion of their bill.

In ownership models, the calculation shifts to compare the upfront investment against cumulative bill credits over the project lifetime, similar to rooftop solar ROI analysis. Using a generation and financial tool to model these scenarios helps developers present accurate subscriber economics during project planning.

State-by-State Availability

Community solar is not available everywhere. As of 2026, approximately 22 U.S. states plus Washington D.C. have active community solar legislation or programs. Another 20+ states are in various stages of policy development. States like Minnesota, New York, Massachusetts, Illinois, and Colorado lead in installed capacity. Before developing or selling community solar, verify that your state has enabling legislation and that the local utility offers virtual net metering or an equivalent billing mechanism.

How Community Solar Projects Are Designed

Community solar projects require careful site selection, system sizing, and subscriber allocation planning. Unlike rooftop solar, where the roof defines the constraints, community solar designers work with open land or large commercial rooftops and must balance generation capacity against projected subscriber demand.

Key design considerations include:

Site selection: Ground-mount sites need flat or gently sloping terrain, proximity to distribution interconnection points, and minimal shading from surrounding structures or vegetation
Interconnection capacity: The local utility distribution circuit must support the planned export capacity without requiring costly grid upgrades
System sizing: Capacity is driven by subscriber demand projections and interconnection limits, not by a single customer’s consumption
Subscriber allocation modeling: Each subscriber’s share must be mapped to expected production, accounting for seasonal variation, panel degradation, and inverter clipping losses

Professional solar design software streamlines this process by combining layout optimization, shading analysis, and production estimation in a single workflow — reducing design iteration time from days to hours.

Practical Guidance

Community solar touches design, installation, and customer acquisition differently than standard residential or commercial projects. Here’s role-specific guidance:

Model production at the subscriber level. Total system output must be divided into subscriber allocations. Use hourly production data to verify that each subscriber’s share meets their expected credit amount across all seasons.
Account for degradation in long-term projections. A 25-year subscriber contract must reflect annual panel degradation (typically 0.4–0.5%/year). Overestimating Year 1 production leads to subscriber dissatisfaction in later years.
Optimize for energy density, not peak capacity. Ground-mount layouts should maximize kWh/acre, not just kWp. Row spacing, tilt angle, and tracker selection all affect long-term yield per unit of land.
Run shading analysis on surrounding terrain. Even ground-mount sites have shading risks — tree lines, adjacent buildings, and future construction. Shadow analysis tools help identify seasonal shading patterns that reduce subscriber value.

Coordinate interconnection early. Community solar projects require utility interconnection studies and approval. Start this process 6–12 months before planned construction — delays are common and can stall entire projects.
Plan for monitoring and O&M contracts. Unlike residential installs, community solar projects need ongoing performance monitoring and maintenance agreements. Subscribers expect consistent production over the contract term.
Verify permitting requirements for ground-mount. Zoning, environmental review, and stormwater management permits add complexity beyond standard rooftop installations. Budget 3–6 months for permitting in most jurisdictions.
Install revenue-grade metering. Subscriber billing depends on accurate production measurement. Revenue-grade meters with data logging are required for virtual net metering compliance in most programs.

Lead with accessibility. The strongest selling point is that renters, condo owners, and shaded properties can now go solar. Frame community solar as “solar for everyone” — not a second-best option.
Show the bill credit math. Subscribers respond to concrete numbers. Present their current bill, the subscription cost, the expected credit, and the net savings. Keep it simple — avoid jargon like “virtual net metering” in customer-facing materials.
Address the portability question upfront. Subscribers will ask what happens if they move. Most programs allow transfer within the same utility territory. Clarify this in the first conversation to remove a common objection.
Use solar design software to generate visual proposals. Even though the panels are off-site, subscribers want to see the project. Show the facility layout, production projections, and their specific allocation to build confidence in the investment.

Frequently Asked Questions

How does community solar work?

A community solar project is a shared solar installation — usually a ground-mounted array or large rooftop system — that multiple customers subscribe to. Each subscriber is allocated a portion of the project’s energy output. Through virtual net metering, their share of the electricity produced is credited to their utility bill each month. Subscribers pay a subscription fee (typically 10-20% below retail rates) and receive bill credits for their allocated production, resulting in net savings without any panels on their property.

Is community solar worth it?

For most subscribers, yes. Community solar typically saves 5-20% on the solar portion of electricity bills with zero upfront cost in subscription models. The value proposition is strongest for renters, condo owners, and homeowners with shaded or unsuitable roofs who have no alternative path to solar savings. However, savings are lower than owning a rooftop system outright. Compare the subscription discount rate, contract length, and cancellation terms before signing up. If you can install rooftop solar, the long-term savings will generally be higher.

Who qualifies for community solar?

Any electricity customer within the service territory of a participating utility can typically qualify for community solar. This includes homeowners, renters, small businesses, nonprofits, and government entities. Some programs have specific eligibility criteria — LMI (low-to-moderate income) programs may require income verification, while others are open to all ratepayers on a first-come, first-served basis. The main requirement is having an active utility account with a participating utility in a state that has community solar legislation.
