TODAY I MAKE SOLAR CHARGER

FIRST I TAKE SOLAR PANEL

THEN I CUT SOLAR PANEL COD I GATE POSITIVE+  AND NEGATIVE- 

 THEN I TAKE 5V REGULATOR        

                                                                                                       

THEN I SOLDER (+) WIRE INPUT AND (-) GROUND 

THEN I TAKE USB CABLE

 

AND CONNECT WITH REGULATOR (+)WIRE OUTPUT AND (-) WIRE GROUND .

WHY WE USE REGULATOR BECAUSE SOLAR PANEL GIVE OUTPUT MORE THEN 5V

AND WE WANT ONLY 5V THAT'S WHY WE USE REGULATE.
