Will I get two bills with community solar?

It depends on your state — and in Illinois, on your specific project. New York and New Jersey use single billing. Maine, Massachusetts, Minnesota and Delaware generally send two. Here's how to tell which applies to you, and how to check you're actually saving either way.

The short answer, by state

Billing model is set by the project, not only by the state. The table reflects how it works in most cases, but individual projects can differ — so confirm it during enrollment before you sign anything.

Illinois is in the middle of a switch

Illinois deserves its own note, because it's changing. The state is moving from dual billing to Utility Consolidated Billing, where your solar charge appears directly on your ComEd or Ameren bill and the utility passes the money to the solar farm owner.

Some Illinois projects have already made the switch. Many haven't. Illinois' Citizens Utility Board describes both models as currently in use, and some municipal programs still tell residents plainly to expect two bills a month. So in Illinois the honest answer is: ask which model your specific project uses. The disclosure form you receive before signing is required to spell it out.

Worth knowing: ComEd's billing system upgrade caused real problems for consolidated-billing subscribers through 2025, with missing credits and erroneous charges. Those were resolved, but it's a reminder to actually read your bill for the first few months either way.

Why the difference exists

It comes down to whether the state requires utilities to handle consolidated billing. Some state programs mandate that the utility apply solar credits and the corresponding charge directly to its own bill. Others leave the solar provider to bill subscribers separately. Neither is better regulation — it's just a different administrative choice, made when each state wrote its program.

If you're on a one-bill (consolidated) project

Nothing changes about how you pay. Your utility bill arrives as usual, with a line showing your solar credits reducing the total and the subscription charge alongside it. You pay one company, the same one you always have. It's genuinely simpler, and it's the direction the whole industry is moving.

If you're on a two-bill (dual) project — the arithmetic

This is where people panic, so here it is worked through slowly.

Say your normal electric bill is $180, and your solar share generated $100 worth of credits that month:

• Utility bill: $180 − $100 credit = you pay $80
• Solar bill: the $100 in credits at a 15% discount = you pay $85
• Total out the door: $165 instead of $180

You paid two bills and came out $15 ahead.

The second bill is not an additional charge. It's you paying for the credit that already came off the first bill — at a discount. Nothing is billed twice. If you only look at the solar invoice in isolation, it looks like a new expense appeared. It didn't; a bigger one shrank.

How to verify you're actually saving

1. Add the two bills together for the month.
2. Compare that total against what your utility bill alone was for the same month last year.
3. Adjust roughly for any rate increase and for how much power you used.

Never judge it from one bill in isolation — that's the mistake almost everyone makes. If the combined total is higher than it should be, something's wrong and it's worth a call.

If the numbers look wrong

Work through it in this order:

1. Check the credit amount matched. The credits deducted on your utility bill should correspond to what your solar provider billed you for. A mismatch usually means a timing lag between the two — utilities and providers don't always sync in the same cycle.
2. Call your solar provider first. They can explain the specific month's production and how your share was calculated.
3. Then your utility, if the credit line on their bill looks wrong.
4. Then your state regulator if neither resolves it — the Illinois Commerce Commission, the NJ Board of Public Utilities, the NY Public Service Commission, or your state's equivalent.

Also worth knowing: credits typically take two to three billing cycles to begin after enrollment. In the first couple of months you may see a solar bill before you see meaningful credits, which looks alarming and usually isn't.

Does two bills mean it's a scam?

No — but it is the single biggest reason people think it is. Someone sees an unexpected invoice, assumes double billing, cancels, and posts about it. That's why we'd rather explain it here than have you discover it when the envelope arrives. More on which community solar risks are real.
