Photovoltaic Roofs: What is the ROI?

Finally, managers must answer difficult questions regarding the financial feasibility of such a project:

• What are the available incentives, rebates, and credits from federal, state, and local governments and utilities in the area?
• What is the potential for an SPPA or other financing options?
• What are the projected installation costs for the chosen system?
• What are the projected energy cost savings?
• What is the projected payback time frame, return on investment, and cash flow?

Performing this type of analysis is critical for managers to properly determine the potential success of a PV system. The final steps are to have a professional design the PV and electrical systems, then to have a qualified contractor perform the installation.
