First off, there is absolutely no reason to cloak your clickbank ID for squidoo. However I definitely have some advice for you.
I sort of consider myself a squidoo expert. I have many lens that make me money but one of my better lens has earned me about 5k this year. Now I know that doesnt sound like a lot but thats not all the money I am making on lens. But its free and it took me like 2 hours to set up like 3 years ago. After owning it for about 6 months its been making me a lot of money.
The first huge flaw in your lens is that you provide absolutely no value to the reader. People can find this solar energy stuff for free online. Its pretty available. If you search for a free method of making solar energy you will be hit with an abundance of crap on it. If you throw up a product people can get for free and provide them no value your dead in the water. You may get a sale here and there but not much more than that.
The way I would have approached this is. Find a great method for making solar energy. Use one of the methods found in the ebook. Give them something of true value. Show them step by step how to do this, give them screen shots or a short vid. Once they use your info and make something successfully or realize your not just trying to sell them something they will be more likely to buy from you.
After you give them this info mention your ebook for sale. Tell them that this way and others are displayed in detail within the ebook. If you give people some truly good content they will trust you and your going to start to get some positive comments on your guest book.
