Fieldwork Sill 350

A 350W kit listed for a windowsill. No battery in the box.

Not tested yet. Scores are sample marks.

These kits have not been measured on a wall, balcony, fence or sill. The scores are sample marks so the list can be reviewed. They are not a reason to buy.

When a kit is tested, this note will name who did it, the dates, and what was measured: listed watts against the 800W cap, where it mounts, whether a battery is in the box, cable length, and whether the model is on the ENA type test register.

Who pays for a link is not part of the score.
