Solar Value Stack Calculator

Solar Value Stack Calculator
(revision 1.8) [XLSB]
NY-Sun developed the Solar Value Stack Calculator to help contractors better estimate compensation for specific solar projects.

We will 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.

For a detailed overview of the calculator and instructions on how to correctly use it, download our Solar Value Stack Calculator Overview [PDF].

The updates in revision 1.8 (revised 8/06/2018) include:

  • Expanded ICAP Alt 1 functionality. User can now project future ICAP rates based on 1, 2, or 3-year historic lookbacks, with seasonal variation
  • Expanded ICAP Alt 2 functionality. User can now project future ICAP rates based on 1 or 2 year historic lookbacks
  • Corrected an error with energy storage. This error under-represented some projects’ revenue by limiting daily discharges to 1 hour, regardless of the energy storage system’s maximum capacity limit
  • Broke out NYSEG into Lower Hudson Valley and Rest of State regions to reflect different ICAP rates
  • Improved calculator run speed
