Solar Pumping System
With 5 decades of engineering expertise in pump industry C.R.I has introduced Solar Pumping systems considering the need of water in remote areas with NO power distribution and understanding the importance of using Green Energy. Solar Pumps are developed with different materials of construction and reasonably good range to meet customer requirement. Incase of DC Solar Pumps, both Screw and Centrifugal type Solar Pumps are available with different head and flow range. The DC Submersible Solar Pumps are powered by C.R.I. Oil filled permanent magnet, brushless DC motors and the Surface Pumps are coupled to specially designed dry brushless DC motors. With regard to AC Pumps. C.R.I Solar Pump Controller is used to convert DC Power generated by PV modules to 3Phase AC Power and drives these pumps. Every component of the pumping system is designed and manufactured to deliver sustained high efficiency.

 


Solar PV Module Functionality
PV Modules collect solar radiation from and actively convert that energy to electricity. PV Modules are comprised of several individual solar cells and function similarly to large –area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy

 


The energy generated from photos striking the surface of the PV Module allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current (D.C.). From which metal contacts in the solar cell can generate electricity. The more solar cells in a PV Module and the higher the quality, the more total electrical output the PV Module can produce. The conversion of sunlight to usable electrical energy is otherwise known as the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode; as such there are no moving parts in a PV Module

 


PV Module Output
Factors that affect the output of PV Modules are weather conditions, shade caused by obstructions to direct sunlight, and the angle and position at which the PV Module is installed.

 


PV Modules delivers the best output when placed in direct sunlight, away from obstructions that might cast shade, and in areas with high regional solar insolation ratings.

 


PV Module efficiency can be optimized by using dynamic mounts that follow the position of the sun in sky and rotate the PV Module to get the maximum amount of direct exposure during the day as possible


Solar Energy Storage System
In our system the collecting device is lead acid battery which collect and stores DC energy Generated from PV Modules. This battery power storage option is available in DC pumps ranging upto 500W. The D.C. Power stored in the battery can be used to operate the pump directly. This process is usually integrated into solar photovoltaic system where energy collected and stored almost instantaneously
