Three cases of PV areas were considered, namely: building roofs, parking area, and PV land plant, in Cairo International Airport, by using the proposed selected PV cleaning methods. This paper aims to apply analysis for PV system energy generation and its components to give initial cost, and annual cost as well as providing cost payback period which is an important indicator to define the amount of time it takes to recover the cost of an investment. Autodesk Revit and Autodesk Green Building Studio, during simulation, can give the annual wind Rose. PVsyst software was used to model the power generation and to design the whole PV system properly. BIM has the ability to achieve a more energy-efficient building to improve the sustainability through energy analysis, solar analysis and wind analysis. Solar system can be installed either fixed or adjustable to increase the amount of solar energy received via preservation the incident solar beam radiation normal to the system surface as possible. Solar energy systems can produce electricity in the day time when sun ray is available and it is cost efficacious.
Airports have merits that promote the financial viability of on-site renewable energy, in particular for solar photovoltaics (PV). Renewable energy has become an increasingly cost-effective commerce preference for airports on account of technological advancement, market ripeness and public-sector investment.
