Other Benefits:

My Motivation:

We wanted to benefit the environment and set an example of good stewardship for the community. Net zero our electric bill and find a wise investment for the future of our congregation.


For a congregation, generally, it is much less complicated to finance a system through an endowment, grant or mortgage.

Experience with Installer:

The experience was extremely positive. CED was very helpful in assisting us in exploring a number of financing options and educating our congregation about the system production, SREC"s, maintenance and warranties. The crew was professional and installed a robust, highly productive system.
