South America, Bolivia
In January 2020, Shenzhen Solartech permanent magnet solar pumping system was successfully installed in Bolivia. Total water head around 36 meters and average daily water flow around 36 tons. The project is used for livestock drinking water in pastoral areas, which not only provides sufficient drinking water for local livestock in the dry season, but also improves the conditions for local herdsmen to raise livestock and promotes the development of local animal husbandry.
This project is powered by 8 pcs 320W solar panels and adopts Solartech SPM41800C036 permanent magnet solar pump, which consists of a PM1800D solar pumping inverter and a 1.5kW centrifugal pump. Solartech PM Solar Pumping Inverter adopts patented dynamic VI maximum power tracking (MPPT) algorithm, which has high reliability and an up to 98% conversion efficiency. The permanent magnet pump adopts permanent magnet (DC brushless) motor excited by rare earth permanent magnet material without excitation coil or excitation current. Compared with the same capacity asynchronous motor, its efficiency is significantly improved by 5%-20%, which achieves a strong competitive advantage of high efficiency.
