System modelling and performance simulation are essential to successful renewable energy project evaluation and implementation. This activity enables a much more thorough analysis of a project's technical and financial implications. Modelling and simulation provide greater clarity through information necessary to support key decisions and risk evaluation of projects.

Designing the specific details of the system including hardware selection and system routing is the final step prior to project implementation. Renewable energy system design for successfully implemented projects is based on the results of the feasibility study; system modelling; and performance simulation. A key target of the design process is appropriate hardware selection, completed within budget for a given system design. IESC successfully meets this goal through its project experience; industry knowledge; technical expertise; and keen problem solving skills.

IESC combines its strong design capabilities with extensive program management experience which spans all project stages from concept to completion. IESC services can include additional measurements and system verification conducted after the conclusion of project construction. This enables performance evaluation and tracking to build a database of information for future improvements to the given project or others.
