Description
PV Modules
Introduction: During the integration of Solartech pumping system,Solartech select exclusively different PV modules with different materials according to different area with different installation conditions for making the highest quality of solar pumping system at a most reasonable cost.
Monocrystalline Silicon Solar Cell
Polycrystalline Silicon Solar Cell
Copper Indium Diselenide Thin-film Solar Cell
Heterojunction with Intrinsic Thin-layer Solar Cell

Solar Pumping System Optimization
Optimization of Single Pump System
A single pump system consists of only one pump,a power-matched solar array and and inverter.The aim of optimization is to reduce the amount of PV modules as could as possible on the premise of filling the requirement of head and capacity.The rotational speed of pump is regulated according to the irradiation on the solar array;when the sunlight reaches its peak,the pump runs at the rated speed,and the output approaches the peak power of the solar array;when the sunlight is less abundant,the speed of pump varies blellow the range of the rated speed;when the speed as low as the capacity becomes zero,the system stops working.So,there are big differences between solar pumping systems and traditional pumping systems in system design,and the system should be optimized according to the requirements of head,capacity,and local conditions of sunlight.

·Determine the optimal average daily operating time and the range of speed governing.
·Choose the optimal head and capacity of the pump.
·Determine the maximum power of PV modules,the best working voltage and connection.
