What are the key materials needed to create a solar panel and the simple steps to assemble it. What would be the desirable size of the panel enough to run a desk fan motor?

If you want to feel better about yourself, you can definitely do this kind of project. Keep in mind however that your payback will take a very long time. Solar panels are rather expensive. Let’s assume for a moment that you are running 50 W fan. This means that you need a solar panel with the area of about 700 Square inches. It will set you back about $300 or more. This panel will have to be exposed to full sun light. Solar panel however produces only DC current. You will need one of two things; fan with special motor or DC to AC inverter. Add another $50. 00. If you run the some fan on the grid power you will use 1KWH of energy in 20 hours. Average cost of 1KWH in USA is about 10 -12 cents. You will have to run your fan for over 3000 Hrs. in order to brake even. Keep in mind that you also need wires, some kind of mounting bracket etc. to make you project work.

Making of solar panel at home level is not possile. But you can buy one of your required size for the use. Price of solar cell is near about INR 200=00 per watt in India, which is approximately 5 US$. Govts. of various states give susidies from 10% to 40%. Many people use thisoption of electrification in India. Solar energy is costlier initially but in the long run it is the cheapest one. 1HP power production by using solar cell needs the investment of INR 300000=00 which is near about 7500=00 US$.

Its much easier and you get more energy with a water heating system. You can make this out of old water radiators boxed in with a glass lid. However, commercial water heating systems will out perform anything that you can make.
Electrical solar panels are really an industrial process if you want more than a few milliamps.

There is no simple way. You'll have to buy relatively expensive cells made out of silicon and then add a power inverter to turn the DC current out of the cells into alternating current to run things in your home. It's not a cheap venture.
