Should I Wait or Buy Now?
5 inputs → your readiness score and a clear verdict
How This Tool Works
Most balcony solar calculators assume the legal question is already settled. It usually isn't. As of September 2026, 9 states have signed plug-in solar into law, another 13 have bills actively advancing through committee or awaiting a governor's signature, and roughly two dozen more have introduced bills that are still moving — or have stalled entirely. Buying today makes sense in a very different way depending on where you land in that spread.
Your state (Question 1) pulls in that state's current legal status. States that have already signed a law — Utah, Maine, Virginia, Colorado, Maryland, New Hampshire, Connecticut, Vermont, and New Jersey — get the highest readiness scores by default, since there's no legal ambiguity left to wait out.
Housing situation (Question 3) matters because HOA and landlord friction is the second-biggest source of delay after state law itself. Colorado, Virginia, and New Jersey explicitly bar HOAs and landlords from banning qualifying systems. Elsewhere, even in a state where plug-in solar is legal, your specific building or association may still say no — this tool flags that risk separately from the legal-status question.
Urgency and bill pain (Questions 4–5) shift the verdict at the margins. If your state's law is still advancing and you're not in a hurry, waiting even a few months can mean buying UL 3700-certified equipment with full legal clarity instead of installing into a gray area. If your electricity bill is a genuine financial strain, that weighs the other way.
Frequently Asked Questions
Is it actually illegal to install where there's no law yet? In almost every case, no — it's a regulatory gray area, since old interconnection rules written for large rooftop systems technically still apply even though nobody intended them to cover a single 400W panel. This tool treats "no law yet" as a reason for caution, not automatically a reason to avoid buying.
Why does California score lower than states with fewer legislative wins? California's SB 868 has passed both legislative chambers and is on the Governor's desk with a September 30, 2026 signing deadline — very close to law. Until it's signed, it scores just below the 9 states with signed laws.
If I'm moving soon, should I buy before or after? Use the "deciding between two states" field. Plug-in kits are portable by design — most can be unmounted and taken with you. If your destination state already has a signed law, buying before you move is often fine.
