Self-consumption is the key lever
Production, cooling, warehouse technology or air-conditioned offices: most commercial demand falls in daylight hours. The higher the share you use yourself, the faster the system pays back, because self-generated power replaces grid electricity including network charges and levies.
The starting point is your load profile in quarter-hour values, available from your metering operator. It shows how large the system should be and whether a battery for peak shaving makes sense.
Flat roof, trapezoidal sheet, sandwich panels
On flat roofs we use ballasted east-west systems that put a lot of capacity on the roof and spread generation over the day; the roof’s load reserve is checked before design. On trapezoidal sheet and sandwich panels we mount with profile clamps and short rails matched to profile and sheet thickness.
- Check of roof build-up, waterproofing and load reserve
- Fire-safety clearances and maintenance walkways in the layout
- Coordination of crane, materials and access times
