Why it earns its place

Less spreadsheet wrangling, fewer call-backs, sign-off you can defend.

Array sized to winter

PV sized to the worst-month sun so the pump still delivers in July.

Pump matched to the well

Duty and head worked for the bore, with real submersible model lines.

Storage over batteries

Tank buffering sized so you store water, not expensive kWh.
