"Community solar is just shared rooftop solar, off-site." Not quite.
The most common framing of community solar treats it like a fractional ownership scheme for a remote solar farm. You "own a share", you "get credited for your share of the power", everyone wins. That mental model is wrong in two ways that matter for your bill.
First, in almost every state the subscriber does not own any equipment. You sign a multi-year subscription with a developer or a community solar broker, and you get a monthly credit on your utility bill based on the project's output multiplied by your subscription share. The developer keeps the federal ITC, the depreciation, and the asset.
Second, and more importantly, the price of the credit you receive is set by state policy, not by the project. In most states the credit is the retail rate (your bundled per-kWh price). In NY post-2019, and increasingly in CA, the credit is a VDER-style value stack that is typically lower. The same solar project earning the same kWh can pay back wildly different amounts depending on which side of a state line it sits.
This is why "community solar saves you 10%" is true in Minnesota and Illinois, marginal in New York, and increasingly unworkable in California unless the project is paired with battery storage. Read on for the mechanism.
How a community solar subscription actually works.
Three things happen every month between the solar project, the utility and your bank account. None of them require you to install anything on your roof.
The project generates kWh
A community solar project is a ground-mounted array, typically 1 to 5 MW, located somewhere in your utility's service territory. Its output meter is read monthly. If you hold a 5% subscription and the project generated 600,000 kWh in May, your share is 30,000 kWh, prorated across all subscribers.
The utility credits your bill
Your utility receives the meter data from the project, multiplies your share by the applicable per-kWh credit price, and posts a credit line item on your bill. In retail-rate states this is essentially your bundled rate (in 2026, around 12 to 25 ¢/kWh depending on state). In value-stack states it is a stack of separate components, fixed for 20 to 25 years per project.
The developer bills your subscription
In a typical subscription, the developer charges you for the same kWh at a discount to the credit (often 10 to 15% less). Your net saving is the gap between the credit you receive and the subscription you pay. In consolidated billing setups, the utility handles both lines on one bill; in dual billing, you see two bills.
The detail that surprises most readers. Your subscription size is usually capped at about 80 to 100% of your historical annual usage. If you over-subscribe, the excess credits roll forward but are often forfeited if not used within 12 months. Right-sizing matters: a 110% subscription in a low-usage household is just a forced loan to the developer.

! States with no community solar program
In the 26 states that do not have community solar enabling laws (most of the Southeast, much of the Mountain West and the Pacific Northwest, and parts of Texas), the option is not available. Virtual net metering is not authorised, and your utility has no obligation to deliver bill credits for off-site generation. A few municipal utilities (Austin Energy, Sacramento SMUD) run their own programs; investor-owned utilities outside the 24 states do not. If you live in one of these states and want solar economics, your only realistic option is rooftop solar under your state's net-metering rules.
Why your state's pricing rule decides whether community solar pays off.
The single most consequential regulatory choice in community solar is how the bill credit is priced. There are four mechanisms in use across the US, with very different consequences for subscribers, developers and non-subscribers.
A Retail-rate credit (MN, MA, NJ, MD, CO, IL ABP)
Credit = your bundled retail per-kWh rate. Most generous to subscribers, but shifts the cost of distribution and policy charges onto non-subscribers since the project does not actually displace those costs.
B Value Stack (NY post-2019)
Credit = energy value + capacity value + environmental value + demand-reduction value + locational system relief value, computed by zone and by year. Locks in for 25 years per project. Closer to grid economic value, lower than retail rate.
C Avoided-cost / Net Billing Tariff (CA NEM 3.0)
Credit = avoided-cost rate (essentially the wholesale price the utility would pay for the same MWh). About 25% of the retail rate. Killed mass-market rooftop and community solar economics in CA unless paired with battery storage that can time-shift exports to high-value evening hours.
D Income-qualified subsidy (IL ILSFA)
Credit = retail rate, but subscriber payment is capped at 50% of the credit. The state Renewable Energy Resources Fund covers the gap. The only program in the US that consistently delivers ~50% bill savings for income-qualified subscribers, with no upfront cost or fees.
The takeaway: when you see a community solar offer advertising "10 to 15% savings", check the pricing model first. In MN, MA or IL ABP that is realistic. In CA post-NEM-3.0 it is rarely true unless storage is paired. In NY post-2019 it depends on which zone the project is in.
The shift away from retail-rate credits.
The single biggest live debate in distributed-solar policy is whether the bill credit should equal the retail rate, the avoided wholesale cost, or something in between. The decisions made in CA and NY since 2019 are now being studied in every other state.
CA NEM 3.0 export value vs prior
CPUC Decision 22-12-056, in effect 15 April 2023, slashed compensation for solar exports to roughly a quarter of the NEM 2.0 retail-rate credit.
NY VDER lock-in term
Once a NY community solar project is sited, the VDER stack price is fixed for 25 years from commercial operation. Long-term certainty for developers, lower than retail.
MN community solar installed
Minnesota leads the US, on the back of a retail-rate credit, an Xcel purchase obligation and no project-size cap. The model the cost-shift critics warn about, in practice.
IRS Section 25D credit
The 30% Residential Clean Energy Credit runs through 2032 for owned rooftop systems. Community solar subscribers cannot claim it; the developer takes the equivalent commercial ITC instead.
Three things the new pricing rules actually mean
- A The retail-rate model is on borrowed time. NY moved off it in 2019, CA in 2023. Massachusetts and Illinois are studying value-of-distributed-energy methodologies. If your state still uses a retail-rate credit, future projects may be priced lower; existing subscriptions are usually grandfathered.
- B Battery storage is the new variable. A community solar project paired with a battery can time-shift exports from low-value midday hours to high-value evening hours. Under CA NBT, a paired project earns 3 to 4 times what a solar-only project earns per exported kWh.
- C Income-qualified programs are the safest entry point. ILSFA in Illinois, low-income carve-outs in NJ, MD and NY, and the federal IRA low-income bonus credit all push developer economics in the direction of low-income subscribers, which translates to no-fee, no-cancellation-penalty contracts. If you qualify, the value is much higher and the contract risk much lower.
Where the community solar bill credit really comes from.
The arithmetic that does not appear in the marketing brochure. The credit you receive is not free money. Four structural mechanics explain where it actually flows from.
In retail-rate states, non-subscribers pay the difference
When the credit is at retail rate but the project only displaces wholesale energy, the gap (often 5 to 10 ¢/kWh) is recovered through general rate cases that lift everyone's distribution charge. Studies in MN, NY and CA all quantify this cost-shift; the political fight is whether the broader societal benefit of more solar offsets the shift.
The federal ITC is the developer's primary funding source
The IRA bumped the project ITC from 26% to 30%, plus 10 percentage points for domestic content, 10 for energy-community siting, and 10 to 20 for low-income subscribers. Stacked, a developer can capture 50 to 60% of project cost as a federal credit. That is what lets them offer the subscription discount that translates to your bill savings.
In ILSFA, the state Renewable Energy Resources Fund pays
Illinois Solar for All is funded by carve-outs of the state Renewable Portfolio Standard procurement budget, supplied by ratepayers via the state's renewable adjustment charge on every electric bill. Low-income subscribers see roughly 50% bill savings; market-rate ratepayers in Illinois fund the gap through their existing renewables surcharge.
In value-stack states, the price reflects grid-economic value
NY VDER prices solar at energy + capacity + environmental + demand-reduction + locational value. There is no implicit cross-subsidy because the price reflects what the grid actually saves. The trade-off: lower subscriber savings, but no cost-shift to non-subscribers. CA NBT goes further still and prices exports at avoided-cost only.
The honest summary: community solar in retail-rate states is partly a private-good (your bill savings), partly a public subsidy (the cost shifted to other customers) and partly a federal subsidy (the ITC the developer captures). In value-stack states it is mostly the federal subsidy and the genuine grid value. None of this is hidden in the rules, but very little of it is in the marketing.
Six checks before you sign a community solar subscription.
Confirm your state has a real program
If you are in one of the 24 enabling states + DC, check the state PUC or energy office page. If you are not, the offer in your inbox is almost certainly a deceptive third-party electricity supply contract dressed up as community solar.
Read the credit pricing mechanism
The contract must state whether your credit is at retail rate, value-stack or avoided-cost. If the developer cannot tell you, walk away. In NY post-2019 ask specifically for the VDER zone the project is sited in.
Right-size the subscription
Aim for 80 to 100% of your annual usage. Most states forfeit credit roll-overs after 12 months. A 110% subscription in a low-usage household just funds the developer for free.
Check the cancellation terms
"No early-termination fee" often hides a "subject to 90-day notice" or "transferability fee". Income-qualified subscribers (ILSFA, NY low-income, MD low-income) are legally protected from fees in some states; verify the law applies.
Use the income-qualified path if you qualify
If your household is at or below 80% of area median income, look at ILSFA in IL, the low-income carve-outs in NY, NJ and MD, and the IRA low-income bonus projects. Bill savings of ~50% with no upfront cost.
Compare with rooftop solar if you own
If you own a home with a usable roof, the IRS Section 25D 30% credit + state net metering (where it survives) usually beats community solar over 20 years. Community solar is the right answer for renters, condo owners and shaded roofs.
Common questions about US community solar.
Community solar lets you subscribe to a share of an off-site solar project and receive a credit on your electricity bill for the energy your share produces. You do not install anything on your roof. You do not own the panels. You sign a subscription, the utility reads the project meter every month, calculates your share of the output, and lines up a credit against your bill. Most subscribers save 5 to 15% on the supply portion of their bill compared with the default utility rate. The savings depend on how the state values the exported power.
24 states plus Washington DC have enabling legislation for community solar as of Q1 2026 (SEIA). The largest fleets sit in Minnesota (over 900 MW, Xcel obligation), New York (NY-Sun + VDER), Massachusetts (SMART), Illinois (ABP + ILSFA), New Jersey, Maryland and Colorado. About 24 GW of community solar pipeline is in development nationally. The rest of the country either prohibits virtual net metering or lacks the enabling rules.
Two mechanisms exist. Virtual net metering (most states): the utility credits your account at or near the retail rate per kWh your share produces. Consolidated billing: the developer bills you for the subscription, the utility separately credits the project on its bill, and the two flows are reconciled monthly. Some states (NY post-2019, soon CA) use a value-stack price instead of the retail rate, combining energy value, capacity value, environmental value and locational benefits. Value-stack pricing is typically below retail but above avoided-cost, and is fixed for 20 to 25 years per project.
This is the central regulatory fight over community solar. When credits are pegged to the retail rate, subscribers receive the full bundled price (energy + transmission + distribution + policy charges). But the energy your share actually delivers to the grid is worth the wholesale rate plus avoided transmission and distribution. The gap (often 5 to 10 ¢/kWh on an 18 ¢/kWh retail bill) is paid by every customer who is not subscribed. That cost-shift is why California moved to NEM 3.0 / Net Billing in April 2023 and why NY moved post-2019 community solar to VDER. States with retail-rate credits are subsidising community solar; states with value-stack pricing are paying for it at something closer to its grid value.
Three. Minnesota: made-in-Minnesota bill credits at the applicable retail rate, no project cap, an Xcel purchase obligation. New York: NY-Sun + VDER, the value stack is generous in zones J (NYC) and K (Long Island) because locational value is highest there. Illinois: ILSFA (Illinois Solar for All) is no-cost for income-qualified subscribers, plus the Adjustable Block Program for market-rate subscribers; both run through the Illinois Power Agency. Massachusetts (SMART), New Jersey, Maryland and Colorado are also strong markets but with lower per-subscriber savings.
No. The IRS Section 25D Residential Clean Energy Credit requires you to own (or finance the purchase of) the solar system. Community solar subscribers do not own the panels, so they cannot claim the 30% credit. The credit goes to the project developer (or the project investor in the case of tax-equity financing) as the federal Investment Tax Credit. The IRA bonus credits (low-income + energy-community + domestic content) can lift the developer ITC to 50% or more, and developers may pass some of that value to subscribers through lower subscription rates, but you cannot claim the credit yourself.
It depends on the contract and the state. Most community solar subscriptions are transferable within the same utility territory. If you move out of state, or out of the utility service area, you typically need to cancel; some contracts charge an early-termination fee, others (notably ILSFA) prohibit fees for low-income subscribers. Always read the cancellation terms before signing. The "no fee, cancel anytime" promise in advertising is often subject to caveats in the small print.
For practical purposes, yes, if you live in a state where the project is local and the developer retains the Renewable Energy Certificates on your behalf. The complication is the same as for any retail green-power plan: a project that would have been built anyway because it cleared a state RPS auction does not give you additionality. The clearest additionality story for community solar is in states where the program is voluntary (i.e. not used to meet a utility RPS obligation) and the project is built specifically because subscribers signed up.
