Pumping System System Application pumping systems can be applied in the area with sunshine and areas lack of electricity, such as: Daily water using Agricultural irrigation drop irrigation,

System Introduction (AC system) pumping system consists of four parts: solar panels, solar pumping inverter, three-phase AC pump and water storage device.

The inverter applies high efficiency MPPT algorithm to maximize power harvested from solar panels. It will make the system to maximize efficiency to get the water as much as possible.

3 Pumping System System Application pumping systems can be applied in the area with sunshine and areas lack of electricity, such as: Daily water using Agricultural irrigation drop irrigation, sprinkling irrigation, flood irrigation) Forestry irrigation Desert control Pasture animal husbandry Rural town and village water supply Desalinization of sea water Scenic fountain etc. System Introduction (AC system) pumping system consists of four parts: solar panels, solar pumping inverter, three-phase AC pump and water storage device. The solar pumping inverter converts DC power produced by solar panels to AC power which drives AC pump to pump water from borehole, river, lake etc. to the storage device. The inverter applies high efficiency MPPT algorithm to maximize power harvested from solar panels. It will make the system to maximize efficiency to get the water as much as possible. The solar pumping system fulfills concept of low carbon,energy conservation, environmental protection to improve the living standard in water-deficient area. More function of solar pump system Accessories will be added in solar pump system to realize more function. AC input function, high voltage solar charger to charge battery to save energy, AC filter to protect pump.

10 Project reference 37kW solar pumping system in Pakistan Pakistan is an energy deficient country.the energy crisis has greatly subdued the country s economic growth with billions of rupees in losses, particularly in the industrial and agricultural sectors. Power consumption has been growing steadily and an average annual increase of 7% has been postulated for the next four years. As a result of this power shortage,the agriculture sector has been facing acute irrigation water shortages. So the solar pumping system is the best choice for the agriculture irrigation. Location of the project: Multan,Pakistan Application: Agriculture irrigation Head: 75m Daily water output: 336~554 m kW solar pumping system in Lahore, Pakistan Project Location Application Head Daily Water Output Running Time Full Load Time Lahore, Pakistan Agriculture irrigation 19m 925~1500m 3 /day 12hours in Summer, 8 hours in Winter 8 hours in Summer, 5 hours in Winter Module Type 250W polycrystalline modules panels 6 strings, each string 18pcs pump Inverter JNP18K5H (18.5kW) Submersible Pump 18.5kW 7.5kW solar pumping system in Turkey This system is installed in Turkey with depth of 165m, one day water output is about 45 m 3. This system we use 2 strings 250W, polycrystalline modules, each string there are 19pcs solar panels. So total 38pcs, 9500W solar panels. The submersible pump is 7.5kw 380V, 50Hz, three pahse pump. The application of this system is for farm irrigation. The solar pump system is the best choice for the area without grid electricity. Compared with diesel pumping system, It is much more cheaper clean, environmental, in long term. 5.5kW solar water pumping system in Morocco As important as electricity may seem, water is essential to life. Bringing life giving water from under the ground using only the power of the sun is very rewarding. The 5.5kW solar pump system was installed Echiibat - El Jadida, Morocco. The depth of the well is 110m, the water requirement is 50m 3 per day. 250w polycrystalline solar panels are used. 2 strings, each string 15pcs, so total 30pcs panels and total power capacity is 7500W. 11kW solar pumping system in Yemen Diesel has been in very short supply in Yemen for the past three years, which has meant increased hardships for Yemen's already hard-pressed farmers. Most of the country is arid and water scarcity is an ever more pressing concern in Yemen. Renewable energy now saves farmer the significant amounts who used to have to fork out for diesel. It also saves their many hours that they used to spend queuing at petrol stations. They no longer hears the sound of their diesel generator pumping water. More and more solar pumping systems are used in Yemen s agriculture irrigation.despite massive potential, renewable energy use is negligible in Yemen. In a country where the bulk of the population is rural and many communities are not connected to the grid, localized solar pump systems are a highly appealing alternative. The start-up cost for solar system amounted to two years worth of diesel bills. After two years, The system will be completely chaper. The 11kW solar pumping system are in stalled in Yemen in 2014, the head is 115m, and flow rate is 17m 3 /h. The solar panels we use are 250W polycrystalline solar panels. 3 strings and each string with 19pcs solar panels. total 57pcs, 14250W. The submersible pump is 9.2kW. 380V, three phase, 50Hz.The rated head is 116m and rated flow rate is 17m 3 /h
