Solar Value Stack Calculator
NY-Sun developed the Solar Value Stack Calculator to help contractors better estimate compensation for specific solar projects. The calculator combines the wholesale price of energy with the distinct elements of distributed energy resources (DERs) that benefit the grid: the avoided carbon emissions, the cost savings to customers and utilities, and other savings from avoiding expensive capital investments. Select the calculator that best fits your project.
We periodically update the calculator—please revisit this page regularly to ensure you are using the most recent version. To download the calculator, you will need a recent version of Microsoft Excel. The password to unlock the file is nysun.
