Assuming you haven't spent the past few years completely immersed in some arboreal forest without even the most meager access to the internet, it is a safe bet to say that you’ve seen the ubiquitous advertisements hawking kits, ebooks, and any number of other mediums with the promise to teach you how to "Build your own solar panels!" I say this because they literally litter the world wide web, leaving nearly every page I visit somehow oddly resembling my fraternity's old house the morning after that toga party we threw during my junior year of college. But, unlike said party, the surprise one finds when finally daring to look beneath the toga is often less than magnificent, which is my very cleverly cheeky way of saying that purchasers of these ebooks and DVDs, et cetera, often find that the supposedly simple process described therein is either far beyond their capabilities, or at the very least it is much more labor-intensive than they had been lead to believe.
Let me say, also, that I'm not saying the whole DIY Solar Panels thing is a bust. On the contrary, I think it shows a great deal of promise. But, the truth is it isn't nearly as easy as most of those ads would have you believe. The process requires skills and patience. The solar cells you will have to acquire are rather delicate and break very easily. You can find them all over eBay by searching for broken solar cells; to be perfectly clear, they still work even though they're broken. The power you get out of them is obviously reduced when compared to a new, pristine cell, but you augment that by piecing together broken cells. In the end, you can build a perfectly working solar panel.
And, the best part is that you can now see how these panels are actually put together, using the free video resource YouTube. You can watch any number of videos that will give you a clear idea of what exactly is involved in putting homemade solar panels together, using what you learn there to make yourself better at the whole process and not such a novice once you decide to shell-out the cash for the expensive teaching ebook or DVD... or, better yet, to completely bypass the costly product and just go it on your own. Yes, some of the videos are that good!
So, here you go, watch and learn. Hopefully, this will better prepare you to make your decision whether or not you are capable of taking on a project of this type. Good luck!
