Savings to Investment (SIR) Calculator: Solar PV + EE

This tool is designed to help property owners, solar PV developers, and Connecticut Green Bank determine the approximate limit on C-PACE financing that can be made available for individual commercial-scale projects contemplated to be completed under the program. Pursuant to the enable law and C-PACE Program Guidelines, all projects funded under C-PACE must achieve a savings-to-investment ratio (“SIR”) greater than 1, whereby “investment” refers solely to dollars sourced via C-PACE. 

Using this tool does not (1) substitute for an energy audit, technical reviewer report, or any other requirement under the C-PACE Program Guidelines, (2) represent an offer for financing or guaranty Connecticut Green Bank approval for the proposed project. 

As a potential participant in the C-PACE Program, you should seek any necessary outside legal counsel, accounting or engineering support to review contracts and energy assumptions and consider carefully the risks associated with accepting C-PACE Program financing, which include, but are not limited to, the following: (1) the Connecticut Green Bank does not guarantee energy savings, (2) information provided herein is for indicative purposes only and not to be relied upon by third parties, (3) fluctuations in energy prices, occupancy or property use may affect the savings associated with a project, and (4) the success of a project may depend in part on various U.S. Federal or State of Connecticut policies and incentives that are subject to change.
