assembling photovoltaic cells yourself interested people a long time ago when the whole panel was too expensive ... with current prices it is useless to try unless you need something very special

for thermal panels it is completely different: thermal panels are too expensive and it is possible to do better and cheaper: in thermal there is no problem of lifespan if we use good materials: we can do everything dismountable and repairable

Bonsoir
live on 30 V resistors it works very well, but only one panel at this stage
for more than 2 years, no failures of electronics ......

Somewhere regarding solar panels and their efficiency,
I had mentioned other possible types of panels, based on fluid electrolyte.
According to the principle of the photoelectric effect.

On this simulation, forget the BATTERY part... unless it's to charge it.

In addition to the previously mentioned principle:

Ok but I guess you can mount the light intensity of the lighting LED way more important right? Furthermore their life (and heat sensitivity) must be higher than that of cells not crystal clear?


NO Ben and I explain:
Silicon is still the silicon and thus the maximum temperature is always 125 ° C. over as the heat exchange surface is very low, the heat transfer resistance is elevated.
Hence problems of heat dissipation.
Tests on LEDs cms allowed me high concentrations but with smoking shell of the diode for the optical settings ......

As against the LED diodes are excellent when we want to detect a light or illumination.
Application: detection of the position of the sun, solar tracker, etc ...

...or even make high voltage direct solar...
with for example 1000 LEDs in series...

Only the high brightness reds, (galium arsenide etc...) with a little sun, and HOP = 1,5 volts.
PAF!! .... 1500 Volts Continuous : Mrgreen:

Compared to 0,5 volts silicon eh...!

Say, try once to think of something other than Battery Current or whatever....
the bindings, in the long run...you know! : roll:

Ah, don't forget, physically, the polarities of the Diodes...
on the symbol, the Negative is in fact a Band with Positive polarity....otherwise the Negative...well it wouldn't pass : Mrgreen:

The LEAST is "balls"who go into the"Positive Holes"(...)
