What is largest solar panel available for a roof?

A facebook page had this item highlighting a small wall panel plugged in, could it be true??

On August 27, 2026, new UK rules made compliant plug-in solar systems legal to buy, self-install, and connect directly to standard household sockets. Each system is limited to 800W AC, while the connected panels can provide up to 2,000W DC.
The small systems use solar panels and a microinverter to supply electricity directly to household circuits, making solar more accessible without conventional rooftop installation. They could be especially useful for renters, apartment residents, and homes without suitable roofs, with government estimates suggesting savings of up to £110 per year.
Safety rules still apply: systems must meet electrical standards, plug directly into a suitable socket, and be notified to the local electricity network operator after installation. Plug-in batteries are not permitted, and planning or landlord restrictions may still apply depending on the property and UK nation.

  • For clarity, the 'upto 2000W DC' from the solar PV modules / panels would be from multiple panels as the highest power panels currently available top out at around 650W with 500W now being typical.  

    Most of the plug-in inverters have dual DC inputs, so can connect two panels directly and some kits I've seen such as Ecoflow, are listing a 1000W DC kit with 4 off, smaller 250W panels to hit the 1000W figure.

    These panels are now getting seriously big, a 650W panel is 2.3m high and 1.1m wide, weighing 32kg so the manual handling becomes an issue, particularly for DIY type installation.
