I need to know where I can buy the parts or find them as scrap to make my own solar panels. Is there a cheap way of buying the panels or can I make them myself.
Unless you have a silicon fab in your basement to make silicon wafers, you aren’t making your own solar panels and there is nothing about this idea at all that will be "cheap".
Your entire idea may be nobel on one level, but it also points out just how uninformed on the subject you are. As an example of what I mean, buying the solar panels is not actually a problem, but it is apparently the only part of the problem you can get your head around, so this is where you are starting with your questions.
Let me throw out a few things for you to consider. First, solar panels tend to be fairly expensive. The absolute cheapest I have ever heard quoted are in the several dollar per watt range and when bought in small quantities, it will likely be up to around $10 per watt.
I have no idea what you want to power, but lets just say you want to run a TV using solar. A TV can easily use 200 watts or more of power, so in the small quantities you are talking about, they could cost $1000 to $2000! If you actually have visions of powering more than this, just add more $$$.
Now, do you realize the solar panel puts out unregulated DC and to run most things, you will need regulated AC so now you need a certain type of inverter. Add some more $$$.
I’ll further guess that you want to actually connect this to the power in your home in some fashion. No utility company in the country will allow you to connect your contraption to their power unless it meets their standards and the work is done by a licensed electrician. More $$$.
The fact is, the only way any of this is economical viable for anyone is because of the incentives that the various levels of government and utilities are currently offering. However, attempting to do it on the "cheap" as you are will also doom you to not being able to qualify for any of the incetivives which are out there.
Here is an installer in AZ who does this work and does it correctly such that you would qualify for the various incentives. Pay special attention to the costs.
