Photovoltaic water pumping system and composition
Blue Carbon Photovoltaic water pumping system is mainly composed of photovoltaic panels, photovoltaic storage machine, inverter and water pump.
The PV pump system utilizes solar energy to drive the water pump to extract water from deep wells, rivers, lakes, reservoirs and other water sources.
The photovoltaic pump utilizes the sun's long-lasting energy without the need for diesel fuel, power grid, or manual duty, which saves manpower to a large extent.
The role of photovoltaic water pumping system
In the past, water pumps were usually driven by electric or diesel motors for water supply, but electric and diesel genset-driven water pump systems not only have high operation and maintenance costs, but also consume fossil energy and damage the ecological environment.Nowadays, photovoltaic water pumping system can be used for water supply, as long as the light resources are abundant, the underground or the surrounding rivers and lakes are rich in water resources, using photovoltaic water pumping system for water supply, it can be used for agricultural irrigation, sand treatment, urban water features, water for life and other fields.
