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,
Generally need to calculate the total flow according to the collector area, a reasonable division of the branch and divided by the number of branches to calculate the branch flow, according to the collector test report on the flow resistance curve calculation and series calculation of the collector pressure drop;
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:Booster pump installed in the solar water heater, the correct location should be where the solar water heater?
After the solar energy should be pressure type, the water by the pressure of the tap water out of the top, there is no such trouble.Now some manufacturers have produced a pressure of fresh water solar energy, not only pressure red, water quality is good, you can drink solar energy.
Q:What is the difference between centrifugal pumps and circulating pumps?
Do not know what you said solar hot water projects specifically include what?
Q:What is a photovoltaic pump?
However, the PV system also has its shortcomings, such as: energy dispersion, intermittent, strong regional. Pre-high cost. The use of solar energy in the absence of any external energy can be used in a flexible and flexible manner for farmland irrigation, providing clean drinking water, developing garden economy, beautifying the park, constructing color fountains, raising fish, raising shrimp pond, For drainage and so on.
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
To the battery pack, and by the battery to the inverter circuit to provide a stable voltage and current, if your pump motor is a single phase 100W, then the inverter power at least greater than the value of 1 times to 1.5 times Caixing,
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
There are many pumps can make solar hot water pressurization, according to the type of sensor diversion switch booster pump, pressure switch booster pump and electronic pressure switch booster pump, variable frequency pump can also be pressurized.
Q:What is the role of solar water pump?
Compatibility is good, photovoltaic power generation can be used in conjunction with other energy, can also be based on the need for photovoltaic systems is very convenient capacity.
