Community Wind Handbook/Calculate Simple Payback
Calculate Simple Payback
The Small Wind Economic Model is a Microsoft Excel spreadsheet that can help you analyze the economics of a small wind electric system and decide whether wind energy will work for you. You provide information about how you will finance the system, the characteristics of your site, and the properties of the system you’re considering. The tool then provides you with a simple payback estimation (it assumes no increase in electricity rates) in years. If the number of years required to regain your capital investment is greater than or almost equal to the life of the system, then wind energy will not be practical for you. A more in-depth explanation of payback with links to additional resources is provided later in this guidebook.
