What plug-in solar laws actually say

Every plug-in solar law does the same basic thing: it lets a small, certified solar kit plug into a home outlet without the utility’s interconnection process. Beyond that they differ, and the differences matter most for renters and for anyone buying a kit right now.

Updated October 2026

1. A size limit

Most laws cap the system at 1,200 W of output. Colorado goes up to 1,920 W. Connecticut allows one device per household. In California the cap is on the AC output of the inverter, not the panels’ label, so check how your state words it.

2. A safety certification

Laws require a kit certified by UL or an equivalent lab. California adds that kits must meet national and state electrical codes and shut off within seconds of a grid outage. The standard written for this is UL 3700, published in December 2025. How UL 3700 works.

3. No interconnection agreement

This is the heart of every law. Normally anything that sends power into the grid needs the utility’s approval. These laws exempt small certified kits. In California the exemption ends on January 1, 2030, unless lawmakers extend it.

4. Landlords and HOAs: mostly left out

The laws mainly stop utilities from blocking plug-in solar. Few protect you from your landlord or HOA:

  • Colorado adds landlord and HOA protections from January 1, 2027.
  • Virginia stops local governments and landlords from banning the devices outright.
  • New York’s bill doesn’t require landlords, co-ops or condo boards to allow it.

What renters should do.

5. Payment for extra power: usually silent

Most laws don’t say whether your utility has to credit power that flows out of your home. Plan as if it’s worth nothing. That’s how our calculator works by default.

6. Start dates and the gap

Signing a law and the law taking effect are different dates. In between, regulators write the details. Connecticut’s utility regulator, for example, had to write installation rules before its law could start.

Common questions

Is there a federal balcony solar law?

No. Each state decides for itself, which is why the rules, size limits and start dates differ.

What happens when California's exemption ends in 2030?

Unless lawmakers extend it, the exemption from utility interconnection rules ends on January 1, 2030. After that, plug-in devices would again need the utility's approval.

Do any laws pay me for extra power?

Most plug-in laws don't address it. California's SB 868, for example, is silent on metering, credits and compensation. Assume extra power is worth nothing unless your utility tells you otherwise.

Can I plug in two kits?

Usually the limit is per home, not per kit. Connecticut allows one device per household up to 1,200 W. Two kits that add up to more than your state's limit aren't covered.
