Solar Energy Savings Calculator

I wish to have installed on the homepage of my site, a calculator that shows savings by using solar energy, in the United States. I don't know if this should be java based but I like it to be calculated on one page, without changing a page for calculation. I need something that is not copyrighted and I know there are calculators that exist online. I wish to have this installed as soon as possible. Please let me know the work you have done in this regard. [login to view URL] This is the look and type of calculator I wish to use. Simple...but the formula will be such as this one at [login to view URL] I cannot find the right formula. The average retail price for Atlanta is 7.63 cents/kWh and that is all I have.

I want it simple and clean. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
