The challenge
Before constructing a 0.98 MWp grid-connected solar plant, the owner needed a credible yield estimate for the available land. The study had to address layout constraints, shading and realistic system losses.
Our approach
- Built the PVsyst assessment using site coordinates and Meteonorm data.
- Iteratively reviewed tilt and row pitch through far-shading simulations.
- Optimised string and parallel configurations.
- Defined DC and AC wiring, module-quality, light-induced degradation, auxiliary and night-consumption losses.
- Modelled near shading from fencing, lighting poles and lightning arresters, including checks on the shortest and longest days.
The outcome
The study established the tilt, pitch and string configuration for the available land. Annual energy, system losses and performance ratio were estimated using the stated assumptions, providing a basis for detailed design. These were modelled estimates, rather than measured operating-generation results.
What this means for the owner
A useful yield estimate connects the proposed layout with its shading and loss assumptions, so the design team can see what the forecast depends on.
