Each case study replays a real sizing in LE LAB, the solar pumping and irrigation sizing application: the need as the client expresses it, the data entered, the results in screenshots, and the reasoning behind every technical choice. No polish: the limitations are told as well.
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: three panels are enough to lift 32 m³ a day to the village reservoir.
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 NGO's request: 100 m³ a day for a town and its livestock, a 50 m borehole, and a generator that now starts only three days a year, 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.
