Product Description
Brief introduction
A solar-powered pump is a pump running on electricity generated by photovoltaic panels which get energy from collected sunlight as opposed to grid electricity or diesel run water pumps. The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has less environmental impact than pumps powered by an internal combustion engine (ICE). Solar pumps are useful where grid electricity is unavailable and alternative sources (in particular wind) do not provide sufficient energy.
This technical specification offers solar powered three phase brushless Direct Current (herein after referred as DC) motor which drives the water pump. This kind of photovoltaic solar powered pump system mainly has three parts:
Solar Panels.
The Controller
The Pump with the Motor
Solar Panel

Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity.
A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output - an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. A single solar module can produce only a limited amount of power; most installations contain multiple modules. There are two kinds of silicon solar cells, called poly crystalline silicon and mono crystalline silicon.
This technical specification offers poly crystalline silicon type of solar panel whose sunlight conversion rate (or called efficiency) is around 12%.
The solar panel consists of the following items.
  Stalinite which protects the solar cell.
  EVA which bonds the stalinite and solar cell.
  Solar cell which is poly crystalline silicon can convert sunlight energy into electricity.
  EVA which bonds the solar cell and the panel backboard.
  Panel backboard which seals, isolates, insulates and waterproofs the solar cell. Normally it is made of TPT or TPE material.
  Aluminium alloy protection layer which functions as sealing and supporting.
  Junction box which protects the whole power generating system, including switches, diode and other electrical components.
  Silica gel which seals the solar module and aluminium alloy frame as well as junction box connections.
The Controller

The purpose of the controller is twofold. Firstly, it matches the output power that the pump receives with the input power available from the solar panels. Secondly, a controller usually provides a low voltage protection, whereby the system is switched off, if the voltage is too low or too high for the operating voltage range of the pump. This increases the lifetime of the pump thus reducing the need for maintenance.
This specification offers the controller equipped with Germany make INFINEON IGBT inverter module, and three phase DC Maximum PowerPoint Tracking system which is frequency conversion and energy saving. The pumping system can be started with one (1) watt power.
The Pump with the Motor

This technical specification offers three phase brushless Direct Current (herein after referred as DC) motor which drives the water pump. The brushless motor shaft is connected with the impeller of the pump, which runs smoothly with high efficiency and longer life. The pump itself is industrial grade with impellers designed anti-blocking and sand-repelling. Stainless pump body, cooper pump head.
