1.1 Introduction of Solar Pumping System
Solar pumping systems produced by Shenzhen Solartech Renewable Energy Co., Ltd
can be applied to living water supply, agricultural irrigation, forestry irrigation, desert
control, pasture animal husbandry, island water supply, and wastewater treatment, and
so on. In recent years, with the promotion of the utilization of new energy resources,
solar pumping systems are more and more applied in civil engineering, city squares,
green parks, tourist destinations, resorts and hotels, as well as fountain landscape in
residential areas.
The system consists of a solar array, a DC pump and a solar DC pumping controller
(see figure 1-1). Based on the design philosophy that it is better to store water than
electricity, there is no energy storing device such as storage battery in the system.

The solar array includes many solar panels connected in series and in parallel, it
absorbs sunlight radiation and converts it into electrical energy, providing energy
source for the whole system. The solar DC pumping controller controls and adjusts
the system operation and converts the DC produced by the solar array into AC in
order to drive the pump, it adjusts the output frequency in real-time according to the
solar radiation to implement the maximum power point tracking (MPPT). The pump,
