These case studies revisit projects sized in LE LAB. For each one, they set out the need, the data used, the solution proposed and the points to watch. The results are placed back in their context, in order to explain the technical choices, their conditions of use and their limits.
Borehole limited to 5 m³/h, storage tank, 10° roof pitch and a generator as backup: a complete case where the tool frames and the trade decides.
A buffer tank filled by gravity, 18 m of elevation gain, 500 m of pipe, no grid and no generator: four panels are enough to lift 32 m³ a day to the village reservoir, as long as the source supplies them at low flow.
A pilot market garden plot, a 30 m well and the deliberate choice to go without a reservoir: coverage is simulated day by day and quantified before signing.
An orchard, an irrigation pond and no power line: the two solutions that hold the duty point are compared array by array, and what really separates them is the equipment.
At 311 m of head the natively hybrid range no longer competes: the three ways of bringing alternating current into a solar pump, and the one that depth imposes.
An NGO's request: 100 m³ a day for a town and its livestock, a 50 m borehole, and a generator confined to the rainy season, the PSk3 hybrid controller combining both sources on its own.
A pastoral association, a captured spring 45 m below the drinking troughs, no grid and no track: the need is calculated from the herd, and the smallest system in the series carries the season.
A river at the foot of a 3 m bank, a drip network already in place, a season from April to October: three panels cover the daily need, while frost-protection sprinkling stays on the thermal installation.
Assumptions stated, figures calculated from the curves published by the manufacturer: the cut-in threshold, the voltage window and the three items the manual makes essential.
