I have got a project from school that I have to make a bulb or a LED glow using solar power.
I googled it and really got confused.
If you can help me then i would be really thankful!!
I just have to generate a little power.
And I do not want It to be toooo costly.
thanks in advance

You can not light bulb in the night by a solar power. Instead you have to charge a battery in the day and left the battery lights the bulb in the night. take a used battery of acar if you have one.
Just select bulb of same voltage to the battery/solar power and that is it.
To light led, you have to know the voltage rating of the leds.
Some leds has 1.5 volt rating and some 3 Volt.
You have to connect 8 sets of led in series if you use 1,5 V leds or take 4 of 3 volt led in series.
