Where can I get cost information on roof mounted photo voltaic cells and water-to-air heat pumps and associated vertical loop systems? I need to know the cost of this equipment and their installation if I am to try and sell the idea of putting them on my ranch-style townhouse to the neighborhood association. Also, I need to know how resistant photo voltaic arrays are to high winds, hail, ice, and snow since I live Nebraska. Furthermore, I need to know if I can afford this equipment since I am an environmental lab technician who ended up in the food processing business.
