Homemade Solar Panel 4S6GGS

1. HOMEMADE SOLAR
PANEL
4S6GGS
Here I’m showing how to make one simple solar panel using
unused break down transistor. The chosen transistor is NPN
metallic TO-3 package and E and B need work.

A solar panel is a photovoltaic cell where light energy is transformed into electrical
energy.
Here I’m showing how to make one simple solar panel using unused break down
transistor. The chosen transistor is NPN metallic TO-3 package. The below picture
shows its image.

Remove the transistor metallic TO-3 package top cover
The small silicon chip inside the able to produce photovolatge when
exposed to sunlight and in the cell the emitter becomes the positive
terminal and the collector becomes the negative terminal.

Test
Ok we get 286.6mV one transistor..

5. HOMEMADE SOLAR PANEL
The cell produced open circuit voltage of 0.1 - 0.5 volts which is normal but it produced
closed circuit current of only 5ma which is too little to be used in any applications. To
light a bright white LED we need minimum 10-15mA current and the panel produced
only 0.2mA which is not enough.
250mV x 10 = 2500mV need 10 transistor in series .
