“How to make a solar power generator
for less than U$S
I
made a small but very useful solar power generator really cheap. It has only
two fundamental parts: the solar panel, and the battery. I used a 12 V 1.8 watts solar panel (U$S
It
is very simple to build it, and can give you hours of fun and use!
MATERIALS:
·
Small solar panel (if you use one bigger
than 5 watts, you will need a charge controller; I did not)
·
Small battery (you can take it from a RC
car)
·
Any low wattage DC appliance (you may need a
resistor depending of the voltage)
·
A switch
·
Wire
PROCEDURE:
1.
Connect the solar panel’s
wires to the battery’s terminals. Connect “+” with
“+”, and “–“ with “-“.
2.
Attach, from the “+” battery, a
wire to one part of the switch.
3.
Attach another wire, from the other part of
the switch, to the “+” terminal of the DC appliance.
4.
Attach one more cable from the
“-“ battery terminal, to the “-“ DC appliance terminal.
With the materials I used, it takes about 3:30 hours to charge a drained
battery in peak power, and about 7:00 hours, on half sunlight. For the
appliance, I used a fan (the ones of the computers) for the DC appliance.
