Community solar cancellation fee calculator
Estimate your exact cancellation fee, whichever structure your contract uses: flat, per-remaining-month, or a declining schedule.
How it works
Two steps to your fee estimate
Step 1
Identify your contract's fee structure
Read your enrollment agreement's cancellation clause carefully, or ask your provider directly which of the three common structures applies. Don't assume, since getting this wrong changes the whole calculation. Check the portability when moving tool too, since a move might avoid this fee entirely.
Step 2
Use this figure in your broader exit decision
Once you have the fee estimate, plug it into the early exit cost calculator for the fuller picture including forgone savings, not just the fee alone.
Understanding cancellation fee structures
Why structure matters as much as the headline number
A "$300 cancellation fee" means something very different depending on whether it's a flat charge, a per-month calculation, or a declining schedule tied to how much of the contract you've already honored. The same headline figure can result in a very different actual cost depending on when in your contract you cancel. The Department of Energy's community solar basics guide lists no exit fees at all as a best practice consumer protection, worth using as your benchmark when comparing offers.
How a declining schedule protects long-tenured subscribers
A declining fee structure recognizes that a subscriber who has honored most of their contract term poses less risk to the provider than one canceling early, so the fee shrinks accordingly as the contract progresses. This is generally considered a more subscriber-friendly structure than a flat fee that stays the same whether you cancel in month 2 or month 118 of a 120-month contract, similar to the graduated risk logic behind the early exit cost calculator. A financed rooftop loan carries a comparable graduated risk in its own way, covered by the prepayment penalty cost calculator.
Why a per-month structure can add up quickly on a long contract
A per-remaining-month fee scales directly with how much time is left, which means canceling early in a long contract, when many months remain, can produce a surprisingly large fee compared to a flat structure. This is worth checking carefully if you're considering a long-term commitment, since it interacts with the contract length comparison tool's tradeoffs in an important way. Start with the DSIRE database if you need the official wording rather than a summary.
What to do with your estimate
Compare the calculated fee against what you'd gain from switching to a better offer or the reason you're considering canceling in the first place. If the fee seems unusually high or unclear, ask your provider directly for clarification before assuming this estimate is final, and check the provider comparison tool to evaluate whether a switch is actually worth the cost. If a billing structure change at your utility is the reason you're reconsidering, the net billing versus net metering comparison explains a related shift some utilities have made that can affect this kind of decision. Check the DSIRE database for whether your state places any limit on cancellation fees, since a small number of states regulate this directly.
Questions
Frequently asked
A flat fee charges the same amount regardless of when you cancel, a per-remaining-month fee scales with how much time is left on your contract, and a declining fee schedule starts high and shrinks the closer you get to the contract's natural end. Check your specific contract to see which structure applies.
This varies by provider, and there's no single dominant structure across the industry. A flat fee is simplest to understand, while a declining schedule is often seen as more subscriber-friendly since it reduces the penalty the longer you've already honored the contract.
Not necessarily in every situation, since a declining fee that starts very high could cost more than a modest flat fee if you cancel early in the contract. Compare the actual dollar figure at your specific cancellation timing rather than assuming one structure type is universally better.
Some providers waive the fee for specific circumstances, such as moving outside their service territory, so it's worth asking directly rather than assuming the fee is fixed no matter what. Review your contract's exact cancellation clause and ask your provider before assuming the calculated figure is unavoidable.
