Worldwide Solar Hoymiles + JA Solar JAM54D41 Kit

Verdict: yes, this exact kit is socket-legal. It is listed Compliant on the ENA G98 Type Test Register under the Plug-in Solar device type (reference WORLD/21447/V1/A5, listed 23 September 2026), which is the listing that lets you plug it into a normal 13A socket yourself under SI 2026/848. No electrician and no Part P is needed. The balcony-sized pick from Worldwide Solar's 31 compliant configurations: 54-cell panels with a mount. The brand is trade-only for now.

Last checked: 10 October 2026. Register data from the ENA API (pulled 10 October 2026).

Quick Facts

What is in the kit

Register string: Worldwide Solar Plug & Play Solar Kit – Hoymiles HMS-800-2WB + 2 Compatible JA Solar JAM54D41 Monofacial Solar Panels + Mounting System. Only the configuration in that entry is covered: swap the panels or inverter and you are outside the listing. Anything not listed above, such as cable length or panel dimensions, is not in the register and we have not verified it.

Where to buy and price

Route: Trade/distributor. We have not found a priced UK consumer page for this exact kit, so we give no price. Until we can, a kit we can price is the safer buy.

Rough annual savings

The register does not state this kit's panel wattage, so we will not invent a figure for it. For reference, a typical 800W kit saves about £170 a year in London with 75% of the output used, or £60 in Manchester if you are out all day, at the 26.32p/kWh cap (method). Check the panel watts on the retailer's page and put them into the calculator.

Run your own numbers: the payback calculator takes your postcode, orientation and usage, and the savings calculator gives a location-accurate generation estimate.

Installing it

Plug it into a standard 13A socket and register it at myplugin.solar within 28 days (about two minutes). One plug-in solar device per household, 800W maximum. Registration replaces the old G98 form for a compliant kit, and the DNO checker tells you which route applies. How notification works.
