    System Features

    Solar pumping system, using the infinite energy from the sun, provides a renewable energy solution based on cost-effectiveness advantages.
    It can be quickly constructed, without power infrastructure and energy storage battery device.
    The system operates automatically and intelligently, reducing the cost of manual management and maintenance.
    Solar pumping inverter controls and regulates the operation of solar pumping system. It drives the pump by converting DC power produced by solar array into AC power and adjusts the output frequency according to solar radiation in real time to implement maximum power point tracking (MPPT).
    The pump, can draw water from deep wells or river, ponds lake to fill into the storage tank or reservoir, or directly connect to irrigation system, fountain system, etc.

    Example of a floating installation project with a submersible solar pump

    The project targets – 10 hectares that require regular water irrigation. Installing a floating PV (solar system) on a pond uses an efficient and ecological solution with remote access for monitoring and control.
    The 16 photovoltaic panels installed , represent 50 m² of the total water surface of 1300m². This system has an output of 5.280 kW, ensuring the water demand of the cultivable surface. The solar pump transports water from the pond through a 550 meters pipe and an elevation gain of 40 meters. This water then feeds a 10, 000 m³ retention pond.
    Floating solar farms offer a wide range of advantages. These floating solar panels avoid the mobilization of the client’s cultivable lands and also reduce natural water evaporation.  The cooling provided by the water improves the performance of the panels, thus avoiding the overheating of the installations for an optimal production. Thanks to 16 floats and their 100 kg support capacity each, the customer can easily circulate on the footbridge and is able to carry out maintenance of the panels if necessary. This floating installation can also withstand extreme weather conditions. The 15° inclination of the panels provides a self-cleaning effect, also preventing snow stagnation in winter.
