Autonomous Photovoltaic Optimizations with Liquids OPALE

[BaudouinLabrique]

Here is the overall plan

Remundo, I found that I could produce more than theoretical Wc under certain conditions: solar-photovoltaic / assistant for-my-installation-solar-t16166-110.html

I inject 3150W for 2800 Wp ...

This occurs after a little rain and a big sun appears ... thermal effect and can be magnifying effect of a few residual drops on the panel?

[Remundo]

the Wc supplied by the manufacturers are measured for 1000 W / m² at 25 ° C under 1,5 AM radiation
Details here

The power loss is about 0,4% / ° C, which also means a power gain of the same rate if they are cooled.

when the panels are cooler, for example at 5 ° C, there is theoretically 20 x 0,4 = 5% more yield.

Thus, 2800 Wp can push up to 2800 x 1,05 = 2940 W under these conditions.

The big big peaks of power occur in cold and / or humid weather, when the sun is playing hide and seek.

Concerning the layer of water on the panels, there is no "magnifying effect", which even if it took place, would not bring more energy to the panel, but there is an effect of anti-reflection layer, the optical index of water, at 1,33, being placed between the index of air (1) and the index of glass (1,5). We can still earn a few% thanks to this.
