SOLAR PUMPING STATION

Educational objectives
• Understanding a photovoltaic system dedicated to the power supply of a water pump.
• Measurements of electrical parameters.
• Analyzing and interpreting results.
• Understanding live wiring tests with putting into service and functioning.
• Studying the efficiency and impacts related to the positioning of the solar panels.
• Studying the solar charge regulator.

Comprises
• 1 photovoltaic solar panel 200Wc mounted on a robust frame that tilts from 5° to 70°.
Open circuit voltage: 57V DC.
Optimum operating voltage: 47V DC.
Short-circuit current: 4.6A.
Optimum operating current: 4.3A.
• 1 30m. link cable.
• 1 100-l tank simulates the underground water source.
• 1 60-l transparent container acts as water reserve.
A tap simulates user consumption and returns water to the tank.
• 1 sealed motor pump 140W- 24DVC-6A. 13l/min capable of pumping dry. It takes water from the tank and fills the reserve water container.
• 2 12V/6Ah batteries supply the pumping station when sunlight is absent.
• 1 24VDC-20A regulator controls battery charging. One 2-button display accessible outside the cabinet enables configuration and viewing of the currents of the solar panel, the battery charge and the lamp and the battery voltage.
• 1 electrical cabinet includes the cabling of all the solar components on connection terminals. A lightning arrester protects the installation and each component is protected by fused circuit-breaker type gPV. The cabling is fully marked and students can easily remove the original strand to do their cabling.
Students can also take voltage and current readings. A main switch isolates the solar panel from the electrical cabinet.
• A switched 24VDC lamp lights the area.
A wheeled frame for passing under doors.
SOLPUITS requires no direct water connection. Once the 80-l tank is filled with water, the system is totally self-contained.
Supplied cabled with detailed instructions and complete practical works.
Dimensions: 750 x 670 x 1980mm. Weight 141kg.
