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:What is a photovoltaic pump?
Advantages of photovoltaic power (1) Reliable: PV power rarely used in moving parts, reliable. (2) safe, no noise, no other pollution. Do not produce any solid, liquid and gas harmful substances, absolutely environmentally friendly. (3) installation and maintenance is simple, low operating costs, suitable for unattended and so on. Especially for its high reliability and concern. (4) good compatibility, photovoltaic power generation can be used in conjunction with other energy, you can also need to make the PV system is easy to capacity. (5) a high degree of standardization, the series can be connected in parallel to meet the needs of different electricity, versatility. (6) solar energy everywhere, a wide range of applications.
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
The water level or water pressure of your tap water is higher than that of solar water heater, and can not be higher than six meters, more than six meters, close to the water tank capacity, easy to leak; if the water level or pressure can not exceed solar energy,
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: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?
High degree of standardization, the series can be connected in parallel to meet the needs of different electricity, versatility.
Q:Solar water heater computer controller shows Sheung Shui, booster pump does not start Sheung Shui, how to do
First look at the control panel signal line is not bad contact, check the water level probe, if these aspects are no problem, then you turn off the power after 3 minutes, at the start.
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:Solar water heater booster pump how to use automatic valve
Choose to use manual switch to force the booster pump can also start, just remember to turn off the pump after the full.
Q:How to use solar panels to drive 50W of circulating water pump, what configuration needs, how to connect?
Of the 24V motor 50W, it takes about 2A current.Therefore, the output current of the battery plate to be larger .... even if it is cloudy, but also make the motor have enough current to stabilize the work.
