IV. Guidelines for installation and exploitation of solar pumps
Photovoltaic module (PV) selection
1. Operating principle:
The photovoltaic module co
nverts the solar energy into electric energy (DC) → DC electric
energy enters into the controll
er → the controller stabilize the voltage, charges the accumulator
(option only for model 3TSS1,38) and produces voltage that conforms the pumps motor → the
pump extracts water
2. Solar pump system's advantages:
a.
Much easier and more widely used than any other electrically driven pumps
b.
Economic and environment friendly, because of renewable energy source usage.
3. Photovoltaic module(s) and accumulator selection
a.
The PV module power is necessary to be selected in a way of being 30% or more than the
power consumed by the pump. The PV voltage must comply with the pumps' operating voltage
and the maximal voltage of the controllers' inlet.
b.
The number of the accumulators used depends from the selection that we made about the
accumulators' voltage and the voltage of the pump. The voltage needed for a certain pump is
formed trough serial connection of the accumulators. The accumulators capacity should be
selected in accordance with the pumps' power and the time during which the accumulator can
supply the pump without being discharged under the threshold.
It is not recommended to
connect accumulators in parallel connection to increase the total capacity, especially in
the cases when the accumulators are with different capacity!!!

* if 2 or more PV modules are to be connected
– please pay attention about the way of the connection
A. If you connect 2 or more PV modules in series, the voltage in the 2 ends of the circuit will be equal to
the voltage of one module multiplied with the panels number, and the current will be equal to the current
of one module.
B. If you connect 2 or more PV modules in parallel, the current of the whole circuit will be equal to the
current of one module multiplied with the modules number, and the voltage will be equal to the voltage
of one module.
C. The connection of photovoltaic modules with different parameters is not recommended!!!
