Eligible Equipment and Improvements

Helios can finance retrofit projects with a wide variety of energy efficiency measures (see samples and table below). In addition, depending on the details of the project and location, other items can be included in the retrofit project such as seismic strengthening, water conservation measures (e.g. irrigation and gray water systems), and new roofing (e.g. if solar panels with 20 year life are being installed on a roof with only 5 years of life remaining).
