What happen when we pour water on solar panel ?
We did experiments on that and obtain higher efficiency when we pour water.

increasing the efficiency of photo voltaic panels by decreasing its temperature using agro materials

we have completed the experiment on photo voltaic cells for increasing its efficiency by reducing its temperature. for that we have used coconut straws and plantain stems as a agro material for cooling purpose. At the result we got increased efficiency.

1st panel - without agro material
2nd panel - with coconut straws
3rd panel - with plantain stem
