Net Metering: Why It Varies So Much by State

Two identical solar systems can have very different payback periods depending on your state's net metering rules. Here's why.

What net metering actually means

When your panels generate more power than your home uses, net metering determines what credit you receive for sending that excess back to the grid.

Full retail credit vs. reduced rates

Some states require utilities to credit excess solar power at the full retail electricity rate; others allow a reduced wholesale rate, which significantly changes your savings math.

Some states are transitioning their policies

Net metering rules have been actively changing in several states as utilities and regulators debate how to handle rising solar adoption — check your state's current rules, not outdated information.

Why this affects your system size decision

In areas with strong net metering, a larger system that overproduces can still make financial sense; in areas with weaker net metering, sizing closer to your actual usage matters more.

How to find your state's rules

Your state's public utilities commission website and your local utility both publish current net metering policies — a local installer should also explain this clearly during your consultation.
