I bought a solar panel 5.5V/30mA,
i measured voltage in sunlight on the back of the panel, 5.6V
good to start .. to play with i soldered wires from the pads on the back of solar panel and brought them to a small pcb where i have a 0.1nF and 10uF cap .. and
stangely i get no voltage across the cap .. though i still get the voltage oin the back plate ..
tried using a diode in series before the cap - still same ..
tried removing the pcb - yet no voltage at the end of the wire !!!
do i need some load or some other circuitry .. or is there something wrong with my measurement
