About PlugWatts
PlugWatts helps U.S. households ask better questions before buying small plug-in solar equipment. We begin with Maryland and publish the source and review date behind material claims.

Our editorial rule
Primary public sources lead claims about rules and safety. Product marketing and public discussions can reveal questions, but they do not replace regulators, utilities, certification records, or site-specific review.
What the Check provides
The Check organizes known conditions and unresolved questions. It does not provide electrical, legal, utility, property, or product approval.
How we review products
This first edition contains researched buying guidance, not hands-on product tests or scored product recommendations. A future review must distinguish manufacturer claims, independently verified records, and our own measurements. We have not verified a local installer directory and do not award provider badges.
Independence and limits
PlugWatts is an independent editorial project, not a utility, regulator, testing laboratory, or installer. This edition sells no kits and contains no affiliate links or paid placements. Research and drafting use AI assistance. A source review date means the cited material was checked; it does not imply a licensed professional approved an installation.
