This is a simple project to get a power supply or charger for most of the usb devices or cell phones .

I used a 18 volts solar panel , though many people here will recomend you to use 9 volts solar panel
Advantage of 18volts panel is that you will get the voltage and required charging current even in the dim light ,(if you use smaller voltage panels , though you get voltage , the current may be too less)


Step 1: CIRCUIT DIAG

BEST AND EASIES WAY TO HAVE T REGULATED 5 VOLTS , IS TO USE A CHEAP 7805 VOLT REG

<p>Hi</p><p>I am interested in building this do you mean 10uf or 10mf or are they interchangeable</p>

<p>I have a 7805CT,can i use it for this project?</p>
