A floating solar array naturally causes shading of the water surface,and with it,a drop in water temperature.This can be advantageous,when employed on reservoirs, as the amount of water
lost through evaporation is reduced,although the rate of evaporation is directly linked to the
size of the area covered by the floating platform.
According to Professor Eicke Weber from UC Berkeley and BEARS(Singapore),in keynote
speech to the 2017 International Floating Solar Symposium,he stated that,“more water
evaporates from reservoirs than is consumed by humans.”For Utilities,this is a lost revenue.
Millions are spent on pumping and treating water to be sold to customers and any loss through
evaporation is a lost income.It is clear that reducing evaporation would benefit the local
population by saving drinking water and keeping costs down.
Of course,shading by the floating system can be compared to other factors such as the
Coverage of the surface by algae. A floating system however, usually covers only a fraction of
The water surface meaning that warmth from sunlight, and oxygen continues to be distributed
Through the water body by its natural convection cycles.Dependent on the footprint of the
Floating Platform,there may also be space between panels where light hits the water, keeping The impact of widespread shading to a minimum.
