Hello and welcome to my another instructable in this i will show you how to make a Solar Powered USB Mobile Charger .it is very simple and easy and i hope you will like it.
What is a solar Panel (copied from wikipedia)?
Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.
A PV module is a packaged, connected assembly of typically 6×10 solar cells. Solar PV panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring. The price of solar power, together with batteries for storage, has continued to fall so that in many countries it is cheaper than ordinary fossil fuel electricity from the grid (there is "grid parity"). For example in 2015, an average home in Europe or the US could use around 3,000 kilowatt-hour (kWh) in electricity each year. Reason of making this: In Our country Pakistan there is very hot So i think i should make a solar powered project .After two days i have the idea of making it so i make it :D

Step 1: Stuff You Will Need
1:5W Solar Panel
2:220v to 5v transformer (i take it from old mobile charger)
4:Tape or glue
Add wires to the solar panel.You should check that wires that they are not faulty.
Connect the USB plug wires to the voltage converter carefully in the sequence:
USB plug + to Volt coverter V+
USB plug - to Volt coverter V-
Connect the solar panel wires to Volt coverter As:
Solar Panel + to Volt converter AC 1
Solar Panel - to Volt converter AC 2
Step 5: Safety
Tape up the wire ends so they do not touch each other :)
If you not do this than it must be danger and cause a short circuit
Put all the stuff on the back side of solar panel with glue or tape.(i use glue)
