Solar Value Stack Calculator

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.

The New Order version of the calculator includes the changes specified in DPS’s April 2019 Value Stack Order, and is meant for projects that qualify under the new rules. The Legacy Value Stack Calculator is for projects that qualified under the legacy value stack. For more details on qualifying dates and eligibility, please see the resources on NYSERDA’s Value Stack main page.

The New Order Calculator contains the following changes.

Revision 2.3 (9/5/2019) of the Value Stack Calculator includes the following changes:

  • Calculators updated to reflect changes in the LIPA tariff, effective 8/1/2019. These changes bring Long Island’s value stack mechanism generally in alignment with the PSC’s April 18, 2019 Order.
  • Adjusted annual output factor for systems using both single-axis trackers and bifacial modules.
