Project overview

This project involved equipping a home with a grid-connected solar plant. Faced with rising electricity costs, the owner wanted to produce part of their own consumption and durably reduce their STEG bill.

Constraints and solutions

Every project has its constraints: limited roof space, imperfect orientation or an existing electrical installation to upgrade. Here is how they were addressed on this project.

Constraints:

  • Limited roof space
  • Seeking the best possible output
  • Integration with the existing electrical installation

Solutions:

  • Optimised panel layout on the available space
  • Adjusted tilt and orientation, high-efficiency modules
  • Switchboard upgrade and dedicated protection

Results

Since commissioning, a large share of consumption has been covered by solar production, with a clear drop in the STEG bill. The installation is monitored by our teams, who check module output and inverter operation every year.
