Solar Mobile Phone charger Circuit:
Here is another idea of harvest Solar energy for charging.This charger can charge almost all types of batteries such as Mobile phone batteries. It uses a solar panel to convert light in to electrical energy.
This circuit explains itself whole procedure.

A 12 volt and 5 watt solar panel is used as source of current.The cells in the panel are made up of semiconductor material which convert sun light energy in to electrical energy.
When the sunlight is a peak means maximum, then solar panel can generate upto 16.5 volts with 400mA current.This current is able to charge mobile phone battery.
Diode D1 allow current to pass in to three regulator ICs to get regulated output.
This output voltage is able to charge Lead Acid battery.
The battery can be connected to point C and ground.
IC2 gives regulated 6 volt to charge NiCd battery. IC3 provides regulated voltage to charge all types of mobile phone batteries which is rated at 3.6 volt.
Red led indicates its charging the battery.

Hi where we can connect USB chargable mobiles ? at B point ?
ReplyDeletePoint A. Because USB power means 5V.
ReplyDeleteif i am using this circuit specifically to charge a phone can i eliminate 2 IC regulators and connect the usb on point A??
ReplyDeleteyes you can
Deletei am so impressed from your energy saving equipment.for more information please visit at
ReplyDeleteElectrostar
can i get 12 volt and 5 watt solar panel in market ,brother?
ReplyDeletehow did u built the ICs and wat parts did u used??
ReplyDeletei haven't built ICs , they are available easily from market
DeleteAny issue with swapping out 7806 & 7812 to use three 7805s, to charge 3 mobile batteries?
ReplyDeleteyes there is no problem, 7805 gives 5V regulated output its fine
Delete...this circuit is for power saving but if i want to use a voltage regulator of 12 volt will it work?
ReplyDeleteyea but you have to increase solar panel voltage little bit more like 14V
Deletewhat are the vallues of capacitors used here

DeleteNice post about Solar Charger. We are also leading manufacturers and suppliers of Solar Charger in Bangalore India
ReplyDelete. hello sir...we must use a charger that can produce 3.7v ..is it ok to use that circuit even the output voltage of 7805 is 5v?..tnx and GODbless.
ReplyDeleteyes its ok
Deletesir should i use a usb port for the output of A.?
ReplyDelete- code monkey
sir how much output current will produce at mobile battery(A) if i have a 9v 5 watts source?.
ReplyDeletecan i construct the circuit by avoiding ic 1 & ic2.....only for mobile charging
