Solar Surface Pumps

ROTOSOL Solar Surface Pumps deliver unmatched efficiency and reliability for applications with suction heads up to 7 meters. Engineered with mono-block construction and PMDC, BLDC, PMSM and AC motors, these pumps offer high efficiency, minimal maintenance.

Each system includes a smart controller with integrated Maximum Power Point Tracking (MPPT), housed in an IP65-rated enclosure for dependable outdoor operation. This ensures early start-up and maximum water delivery by optimizing voltage-current performance under varying solar conditions.

4G RMS and remote ON-OFF are standard features. ROTOSOL surface pumps are ideal for canal irrigation, drip and sprinkler systems, and long-distance water transfer.

Advantages

  • Zero Electricity Bills :
    Solar pumps run entirely on sunlight — no monthly electricity cost and no fuel expenses.
  • Extremely Low Operating Cost :
    Once installed, the running cost is almost zero compared to diesel or grid-powered pumps.
  • Reliable Water Supply Anywhere :
    Works in remote villages, farms, and off-grid areas where electricity is unreliable or unavailable.
  • Long Life & Low Maintenance :
    Solar pumps have very few moving parts, ensuring lesser wear and tear and longer service life.
  • Environment-Friendly :
    Runs on clean solar energy → no pollution, no noise, no CO₂ emissions.
  • More Water Output During Peak Sunlight :
    Maximum water discharge during bright sunshine hours — ideal for irrigation cycles.
  • Best for Drip & Sprinkler Irrigation :
    Stable, high-efficiency output makes it perfect for modern irrigation systems.
  • Reduced Dependency on Labour :
    Automated operation means farmers don’t need to switch pumps on/off manually.
  • Safe & Shock-Free :
    No risk of electrical shocks in the field — much safer than traditional electric pumps.
  • Government Subsidy Benefits:
    Eligible for PM-KUSUM and state solar pump subsidy schemes, lowering cost of ownership.
  • Works Even in Low-Light Conditions :
    Advanced BLDC/PMDC solar pumps (like ROTOSOL) perform efficiently even during cloudy mornings and evenings.
  • Long-Term Investment with Quick Payback :
    Saves diesel/electricity cost → Payback usually in 2–4 years, then free water for 15–20 years.
