Solar-Powered Water Pumping

Solar Pumping Community System

Solar photovoltaic (PV) pumping systems are now the most cost-effective solution over a 15-year lifecycle for rural community water schemes.

System Architecture

  • Direct PV-to-Water: Electricity from solar panels drives a high-efficiency brushless DC pump (helical rotor or centrifugal) that lifts water directly into an elevated header tank.
  • Zero Battery Bank: Eliminating chemical batteries avoids recurring replacement costs every 3–5 years and eliminates battery theft risks.
  • Automated MPPT Controllers: Maximum Power Point Tracking (MPPT) optimizes pump speed during morning and late afternoon low-light conditions.
