From 9.5 to 27.5 kWp.

The twenty-two reference-project URLs under /portfolio/, each naming a rooftop solar system by size, storage and mounting — the one part of the company’s work the URL list describes in any detail.

With battery storage

Solaranlage mit Batteriespeicher at 9.5, 10 (five projects, one on a flat-roof construction), 11 (two), 14 (three), 16, 17.5, 17.6, 21.5, 27 and 27.5 kWp (the last on a Flachdachkonstruktion).

Without, or mixed mounting

10 kWp on a flat-roof construction; 12 kWp with Schräg- und Flachdachkonstruktion (pitched and flat roof); 15.5 kWp; 16.5 kWp pitched and flat roof.

Reading the list

The sizes are residential and small-commercial — a 10 kWp roof is a large house — which fits a regional installer rather than a utility. The duplicated slugs (-2 through -5) mean several projects shared a title. Because every page returned the maintenance screen, no photographs, locations or dates exist in the archive and none are reproduced. The twenty-two URLs redirect here.
