The solar panels make up most (up to 80%) of the systems cost.The size of the PV-system is directly dependent on the size of the pump, the amount of water that is required (m³/d) and the solar irradiance available.
I must explain to you how all this Solar Water Pump
A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps.
The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has a less environmental impact than pumps powered by an internal combustion engine (ICE).
Solar pumps are useful where grid electricity is unavailable and alternative sources (in particular wind) do not provide sufficient energy.
I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete
