The prices column is the easiest to fill badly, so it has the strictest rule on the board.
| Requirement | What it stops |
|---|---|
| A named device | A card that says solar kit and means nothing |
| Registered on the ENA Type Test Register | A card for something that has not been assessed as compliant. Registration and confirmation are required before a device may be placed on the market, so this is the test that settles it |
| A named seller | A figure circulating with nobody attached to it |
| The date it was seen | A price that was true once and is quietly wrong now |
We have read the register directly and can confirm one device on it. UK retail prices remain something we have not sourced from anywhere we would repeat, and the figures floating around vendor posts are not evidence. Nothing we have seen carries all four.
They get used interchangeably and they are not the same thing.
| Figure | What it is |
|---|---|
| 800 VA | The most a compliant device may deliver to the mains. The statutory instrument separately fixes rated alternating current output at 800 watts, which is a different quantity again |
| 2000 W | The most the panels may total on the direct current side, feeding that inverter |
Above 960 W of panel capacity the manufacturer has to advise you to consider a professional assessment of your existing electrical installation. A large array at a keen price may carry that recommendation with it, and almost no listing mentions the figure.
| Not here | Why not |
|---|---|
| Affiliate links | They turn the running order into a commercial decision the reader cannot see |
| Paid placement | Same problem, less subtly |
| Urgency devices | Timers and stock counters are pressure, not information |
| Payback claims | They need a price, a tariff and an assumption about your daytime use. We hold none of those from a source we would cite |
