La photovoltaïque flottante [English]

Brief Introduction to Solar PV Although solar energy has been, is, and will be the most abundant source of energy on Earth, it was not until 1839 that Alexandre Edmond Becquerel observed that the sunlight striking certain materials generated electric current. That is, he discovered the photovoltaic effect. Forty-four more years were needed to develop En savoir plus surLa photovoltaïque flottante [English][…]
