Balcony Solar in Delaware
Delaware's SB 270 would cover portable solar generation devices under Title 26. It's notable for referencing the NEC and IEEE 1547 — and explicitly not requiring UL certification. In Senate committee since March 2026.
Reviewed August 6, 2026 against primary sources. Laws change — the sources below let you re-check.
Would Delaware's bill require UL 3700?
No — the bill does not name UL 3700.
References the NEC and IEEE 1547 and explicitly does not require UL certification. Does not name UL 3700.
Why this matters: “certified by UL” names an organization; “certified to UL 3700” names a plug-in-PV standard. They are not the same claim. Full explainer →
What's still unsettled
- In Senate Environment, Energy & Transportation Committee (March 2026); not yet law.
Before you buy in Delaware
This bill is not law yet — until it passes and takes effect, Delaware's existing utility and electrical rules apply. Even once it passes, the gear has to actually be certified to what the law asks, and today no plug-in kit sold in the US carries UL 3700 yet. What "UL 3700 certified" really means →
