Products

Solar Pumping System supplied by Shenzhen Solartech Renewable Energy Company(manufacturer) can be applied to daily use (ground water), agricultural irrigation, forestry irrigation, desert control, pasture animal husbandry, water supply for islands, wastewater treatment engineering, and so on. Solartech” Solar water pump System is dispensed with energy storing devices, and stores water instead of electricity. It improves the reliability of the device, at the same time, it lowers the construction and maintenance costs of the irrigation system dramatically.

In recent years, with the promotion of the utilization of new energy resources, Solar Pumping System is more and more used in municipal engineering, city centre squares, parks, tourist sites, resorts and hotels, the landscapes and fountain irrigation systems in the residential areas.

Technical Features

Optimization of Single Pump System


A single solar irrigation system consists of only one pump, a power -matched solar array and an inverter . The aim of optimization is to reduce the amount of PV modules as much 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 bellow the range of the rated speed; when the speed as low as the capacity becomes zero, the solar pumping system stops working. So, there are big differences between solar irriation 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 method of connection.
 
Optimization of Multi-pump Systems

There are several pumps in a multi-pump system. The pumps can be driven either by only one high-power inverter, or by several matching inverters. In the case of large capacity demand, the operation of the multi-pump system is more flexible. By switching solar arrays and pumps, all of the pumps run in MPPT mode when the sunlight is abundant, while some pumps will be shut down and all solar arrays supply power intensively for the rest running pumps when irradiation is weak. Based on the optimization of single pump system, the range of speed can be further optimized, and the photovoltaic(PV) pumping system always works with high efficiency.

Q:Will the next solar hot water system, the solar energy pump how to select the number,
But not over the national standard will be able to immediately design, the need for some experience, the pump chooses this thing unreasonable, the power will be several times different, many people engage in heat for many years are not good pump.
Q:Does the balcony wall - mounted solar energy require a circulating pump?
The so-called natural circulation, is your home balcony collector (flat collector or U-tube collector) to absorb solar light heat, the collector medium using cold water sink hot water floating automatically heat will be passed to the tank
Q:Solar water heater booster pump how to use automatic valve
The general flow control of the booster pump can not be used, with the general self-priming pump can be, if installed on the charge, when the solar energy needs water, open the other faucet, you can press the solar up, or
Q:On the issue of pumps and solar panels
Pump head and power sure and pump power and methods such as centrifugal pumps ~ but this full business can give you recommended.
Q:How does the solar self-priming pump be installed?
Installation to minimize the hydraulic loss of the suction pipe, not less than 90 ° elbow, 90 ° elbow on the import pipeline should not be more than 2, the pump inlet should be set to filter, to prevent large impurities into the pump , To ensure the normal operation of the pump, the installation as much as possible to reduce the import pipeline long way (this will reduce the import pipeline air, thereby reducing the self-absorption time, increase efficiency).
Q:What is the pump for solar hot water
If it is by way of manual pressurization, then it is more, all in line with the head of the flow of hot water pump can be.
Q:What is the role of solar water pump?
Solar water pump itself, reliable: photovoltaic power rarely used to move parts, reliable work.
Q:Solar water heater automatic pressurized water pump does not turn how maintenance
If you do not turn the pressure pump is the problem. If the pump itself is the problem, then you can only go to a professional place to repair, if the coil is broken, throw directly to buy a new bar Repair is more expensive and can not guarantee quality
Q:The problem of installing pressurized water pump in solar hot water outlet pipe
in order to facilitate the maintenance and the use of safety, in the pump inlet and outlet of the pipeline to install a control valve and pump near the installation of a pressure gauge to ensure that the rated head and flow within the operation to ensure that the pump normal operation, Pump life.
Q:Solar water heater before the booster pump is now changed into tap water how to get
You can then install a water tank on the top of the three, you still have to use the water pump to the water tank inside, so the effect is the same, might as well not change.
