Solar Pumps for a Greener Tomorrow
Solar Pumps for a Greener Tomorrow
From dry zone paddy fields in Anuradhapura to misty greenhouse terraces in Nuwara Eliya, our customized solar hydraulic systems deliver reliable water at zero fuel cost.
Paddy cultivation demands high water discharge during land soaking, mudding, and transplanting. During dry Yala spells, fuel costs for conventional diesel pumps can consume up to 35% of a farmer's total seasonal earnings.
Lanka Sunrays high-flow surface and canal pumping systems deliver between 30,000 to 60,000 Liters per hour directly into feeder canals and field bunds from dawn till dusk without consuming a single drop of fuel.
Commercial horticulture crops (capsicum, tomato, cucumber, strawberries) in Nuwara Eliya, Badulla, and Matale require steady pressure regulation and automated fertigation. Voltage fluctuations from the national grid frequently damage conventional pump motors.
Our smart solar drip stations maintain a constant 2.5 to 4.0 Bar pressure output, ensuring uniform water and nutrient distribution across all dripper nozzles with zero risk of pressure dropouts or dripper blowouts.
Estate properties across Kurunegala, Ratnapura, and Gampaha often span hilly terrain where water must be lifted from deep valley streams to elevated hill-top reservoirs over 100 to 150 meters vertically.
Lanka Sunrays designs high-head multistage solar systems capable of pushing water up steep slopes into overhead concrete tanks during peak sunlight hours. From there, water is gravity-fed across wide acres at night.
In dry districts such as Anuradhapura, Jaffna, Hambantota, and Monaragala, shallow water tables dry up during prolonged dry seasons. Farmers must rely on 150 to 350+ foot deep tube-wells with high mineral and sand content.
Our specialized SS304/SS316 stainless steel multi-stage submersible pumps feature sand-resistant floating impellers and dry-run sensors, ensuring consistent deep water extraction without overheating or seizing.
A dairy cow requires up to 100 to 150 liters of clean drinking water daily to maintain peak milk production. In poultry broiler sheds, continuous water supply is critical for high-pressure evaporative cooling nozzles to prevent heat mortality.
Lanka Sunrays automated livestock water systems fill central header tanks continuously with auto-float switches, ensuring animal drinking troughs and shed misting nozzles are never dry.
Many rural villages, schools, religious shrines, and farming societies in the Northern, Eastern, and North Central provinces lack access to the national water grid and rely on contaminated shallow wells.
We design solar-powered community potable water stations with elevated storage towers and water purification (Reverse Osmosis / filtration) integration, providing safe drinking water for 100 to 500+ families at zero operating energy cost.
Scientific Precision
Every system is scientifically engineered based on accurate hydraulic data.
We measure static water depth, seasonal drawdown, pipe elevation, and pipe friction losses.
We map local peak sunshine hours (PSH) using satellite radiation data for your specific district.
We select the exact pump impeller and VFD frequency parameters for optimal daily water delivery.
Full installation, flow rate testing, lightning surge protection check, and farmer training.
