Solar pumps range in size from small pumps to powered fountains, as well as large pumps for pumping water from underground aquifers. Built-in panels are typically used for smaller pumps, while larger pumps require separate installations. Photovoltaic power supplies rarely use moving parts and work reliably. Safe, no noise, no other pollution. It does not produce any solid, liquid and gaseous harmful substances, absolutely environmentally friendly. Simple installation and maintenance, low operating cost, suitable for unattended and other advantages. In particular, it is attracting attention for its high reliability. Good compatibility, photovoltaic power generation can be used with other energy sources, and the photovoltaic system can also be easily increased according to needs. The degree of standardization is high, and the components can be connected in series and parallel to meet the needs of different power consumption, and the versatility is strong. Green environmental protection, energy saving, solar energy everywhere, wide range of applications, etc.
