LSZAC Solar Stainless Steel Submersible Borewell Pumps

Introduction

The existence of human life in rural India depends largely on the availability of clean water to people, livestock, and crops. Farmers in rural India can only become prosperous if there is the availability of clean water for their farms, homes, and livestock. In many parts of India, there is a shortage of reliable power for homes and irrigation of fields where the Lubi LSZ series of Solar Submersible Pumping systems can make a remarkable contribution. 
The LSZ Solar Submersible Pumping system offered by Lubi is a state-of-the-art high technology product designed to provide a green and energy-efficient solution for a reliable water supply where there is no access to clean water and electricity. 

 

The LSZ Solar Submersible Pumping system comprises the following equipment. 

•    Solar stainless steel submersible borewell pump
•    Solar photovoltaic panels with mounting structure 
•    Automatic controller for the solar pump
•    Cables and accessories.

Minimum Cost of Ownership

Very often investment decisions for pumps are based only on the purchase cost of the pump. This initial purchase cost is a fraction of owning and operating a pump over its entire life span. The initial cost for diesel engine-driven pumps is just 5% of the total life cycle cost with the operation (energy) and maintenance cost contributing to 85% and 10% respectively.

Solar water pumping systems when compared to diesel engine-driven pump sets are much higher in the initial purchase cost but over the life cycle of the solar pumping system, they provide significant financial savings in terms of operation (energy) and maintenance costs. Typically when solar pumps are compared with diesel engine pumps they offer a breakeven in costs within 4 to 8 years depending on site conditions, installations cost, and model specification. After the breakeven, the solar pumping systems provide significant cost savings to the owners.
