Does it difficult to design a solar pumping systems? Not at all.
Actually, you can design by yourselves even if you just know little about it. There are some tips to help u on designing solar water pumping systems..
Structure of solar water pumping system
First of all, let’s take a look at the structure of solar water pumping system.
Solar pumping system consists of water pumps, solar pumping inverter and solar panels. Solar panels generate electricity, and solar pumping inverters convert DC power into AC to drive pump and adjust output frequency according to sunlight, with complete system protection such as over-voltage, overload and so on. It can be made in to a hybrid system of solar and grid/ generator. Also, the remote control function is available. We can monitor the system through computer and mobile phone.
Design a solar water pumping system
Now let’s start the design.
1:According to you demand on head and flow rate
Step 1. Choose the right pump according to your demand on head and flow rate, as well as electricity demand and working condition. Flow is the the volume water you need every hour or every day,head is the height of lifting water.
2:Choose solar pumping inverter
Step 2 Choose solar pumping inverter.for the chosen pump,according to the information of parameters of the pump. (AC / DC / single / three-phase / 220V / 50Hz), pump power,( W / kW / HP), working condition(Indoor / outdoor / Other), it will be Reduce capacity to use because Cooling function of inverter will decrease in high altitude area with thin air.
3:Choose solar modules
Step 3 Choose Solar modules according to the power of pump, the condition of solar. (strength of sunshine depend on latitude and longitude，check on the NASA), Generally, we will use 1.5 times of the pump power of solar pane. But if want more water output, we can increase the capacity of solar modules..
According to the above, you can design a professional solar pumping system, learnt it?
