Overview
- UK ministers say plug‑in solar kits could reach supermarkets and online stores this summer at around £400–£500, with plans to allow systems up to 800 watts.
- New UK guidance in development focuses on safety features such as automatic shutoff to protect grid workers, product certification, and required notifications to the local network operator.
- Tenants may still need landlord or freeholder consent, and experts warn that lease terms, shared building insurance, high‑rise safety rules, and older home wiring could slow adoption.
- Utah, Maine and Virginia now allow small plug‑and‑play systems, with Maine’s law taking effect in July and requiring UL‑style certification, an automatic shutoff, utility notice for larger kits, and a licensed electrician for 420–1,200‑watt setups.
- Governments pitch these kits as an affordable entry to solar—typically 200–1,200 watts—costing about £/$400 and cutting bills by up to £110 a year in the UK, with Germany’s roughly one million registered units and interest in about twenty more U.S. states showing rapid momentum.
