Solar Pump Products

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.

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.

Solar Submersible Pumps

Discover the power and reliability of ROTOSOL’s deep well solar submersible pumps - engineered for durability, efficiency, and reliable performance.

Crafted from high-grade AISI 304 stainless steel, they offer superior corrosion resistance and long-term reliability to deliver exceptional performance across a wide range of applications. These pumps are available with BLDC, PMSM and AC motors. Designed to operate efficiently on photovoltaic arrays from 900Wp to 10,000Wp. These pumps offer a sustainable solution for water extraction in remote and off-grid locations

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. Built-in protections against reverse polarity, overload, overheating, and dry running—along with fault diagnostics—provide safe, reliable, and hassle-free operation.

Controllers

A solar pump controller is the brain of a solar-powered water pumping system. A solar pump always operates through the controller; The Controller regulates voltage and frequency and protects both the pump and motor from damage.

Even under fluctuating sunlight, the controller ensures smooth and efficient operation, making solar pumping dependable for irrigation, livestock water, and rural supply.
