Simulation and Analysis of Solar PV System under Shading Condition using...

• To study the effects of shading and PV cell junction temperature in a large interconnected solar plant
• 
  
• To implement shading effects in a solar photovoltaics (PV) plant
• 
  
• To improve the maximum power and to protect the solar panel from overheating, the Solar Plant block comprises bypass and blocking diodes. 

This example shows how to implement shading effects in a solar photovoltaics (PV) plant or module.

To study the effects of shading and PV cell junction temperature in a large interconnected solar plant or a single PV module. There are a number of different approaches that can be applied in PV system design to reduce shading losses.

These include the use of Different Stringing Arrangements, Bypass Diodes, and Module-level Power Electronics (MLPEs). A blocking diode allows the flow of current from a solar panel to the battery but prevents/blocks the flow of current from battery to solar panel thereby preventing the battery from discharging. Bypass diodes are used in PV modules to prevent the application of high reverse voltage across the cells in the event of shading.
