Photovoltaic Machine Making Hot Water for Human Green

Photovoltaic Machine Making Hot Water for Human Green


Human Green at JeJu Isaland is green technology company Ltd, and it has developed many products.

The below product is the model made by us using f=140(it is Diypro's early product), and now it is improved more than before.

Heating pipe is placed inside it,  solar gathered by fresnel lens makes hot water.

Fresnel lens f=140 300*300 produced by Diypro were used for the machine.



Currently, we are researching the relative deformation of the lens arising from the high temperature.


We have a lot of know-how about solar lighting and solar power, and have been developing many products and applications with other companies, focusing the parts which Fresnel lens is used for.
