NEM and expansions

Expand your solar
and keep NEM.

Some homeowners can add solar and keep the rest of their original NEM 1.0 or 2.0 term. It depends on your utility and the design.

How we approach it.

Read your current agreement

We confirm your tariff, your approved system size, and how many years of NEM you have left.

Plan the new panels

Non-export and multi-tariff designs can let your original system keep its NEM terms, if your utility approves.

Consider a battery

Storage lets you use more of your own solar and can provide backup. We check whether it pays off at your rates.

Helpful to have

  • A recent electric bill
  • Your Permission to Operate (PTO) letter
  • Details on your current equipment

NEM questions.

What is a non-export addition?

It’s an addition with controls that limit how much power it sends to the grid. Whether it protects your NEM still depends on the design and utility approval.

What is a multi-tariff setup?

Some utilities let the original system and the new panels be credited under different tariffs. That can let the original system keep its NEM term.

Can I just add a battery?

Usually. We make sure the battery works with your equipment and meets your utility’s storage rules.

If I keep NEM, will my bill stay the same?

Not necessarily. NEM controls how you’re credited for power you send to the grid. Your usage, rates, and fixed charges can still change.
