Net metering by state: what actually transfers to the buyer

Of everything that can quietly change the value of a solar home at resale, net metering is the one people most often get wrong — because it's invisible until the electric bill arrives. A generous, grandfathered net-metering rate can be worth thousands of dollars a year to whoever owns the system. But whether that rate follows the panels to the next owner, resets to a stingier successor tariff, or disappears entirely depends on the state and the specific utility. Here's how to think about it, and exactly what to verify before you buy or sell.

Net metering, net billing, and grandfathering

Net metering credits you for the excess power your system sends to the grid, often at or near the full retail rate — the most valuable arrangement. Many states have since moved to net billing (California's NEM 3.0 is the best-known example), which pays a lower, market-based rate and lengthens payback. When a state changes its rules, existing systems are usually grandfathered onto the older, better terms for a set number of years. That grandfathered status is the asset — and the question at resale is whether it survives a change of owner.

Why "does it transfer?" has no single answer

There is no national rule. Transfer treatment is set state by state and, within a state, sometimes utility by utility. Broadly, you'll encounter three patterns:

• Transfers with the home. The grandfathered tariff stays attached to the system/meter for its remaining eligibility period regardless of who owns the house. Best case for a buyer.
• Transfers for the remaining term only. The buyer inherits the grandfathered rate, but only until the original grandfathering window closes — which may be sooner than they assume.
• Resets on sale or change of account. Some rules tie grandfathering to the original customer; a new account holder is moved to the current (less generous) tariff. Worst case — the "low bill" the listing advertised evaporates for the buyer.

How much value is at stake

It's not trivial. Depending on system size, local rates, and how much power the home exports, the gap between a grandfathered full-retail net-metering rate and a successor net-billing rate can run from a few hundred to a couple of thousand dollars a year. Over the remaining life of a system, that's a five-figure swing in the value the solar contributes to the home — which is exactly why it belongs in the conversation before a price is set.

What to verify before you buy or sell

1. The utility and rate schedule. Identify the serving utility and the exact net-metering/net-billing schedule the system is on today.
2. Grandfathering status and remaining years. Is the system grandfathered, and until when?
3. Transfer rule on change of ownership. Does the tariff stay, stay-for-a-term, or reset when the account changes hands? Confirm with the utility in writing.
4. Account transfer mechanics. Some utilities require a specific process to move net-metering to the new owner; missing it can drop the system to a default rate.
