LPO provides debt financing for the commercial deployment of large-scale energy projects; however, for research, developement, and demonstration (RD&D) and smaller projects, other offices within DOE offer funding and financing opportunities. For example, the Homeowner’s Guide to Going Solar provides valuable information from DOE's Solar Energy Technologies Office about financing home and small commercial solar systems.  

After reading about the respective program's requirements, potential applicants are encouraged to seek a pre-application consultation to discuss eligiblity requirements and the application process directly with LPO staff.
