5 Enrollments Level : IntermediateRelevance
In light of global climate goals and rising energy demand, rooftop photovoltaic (PV) systems are a key solution for clean, decentralized electricity production. Their scalability, cost-effectiveness, and growing policy support for self-consumption make them central to sustainable energy strategies.
The successful deployment of a rooftop PV system depends not only on the availability of surface area and sunlight, but also on a thorough understanding of its technical and financial feasibility.
This building block provides essential insights into the technical and financial feasibility of a PV system, including site assessment, system performance modelling, consumption and production analysis, CAPEX and OPEX evaluation, and risk and sensitivity analysis. It equips students with a detailed overview of how to evaluate project viability, supporting informed decision-making in PV development and implementation.
Abstract
This building block offers a structured introduction to the technical and financial feasibility of rooftop photovoltaic (PV) systems. It equips students with the skills to assess project viability from both a performance and economic perspective.
The module starts with a general introduction, followed by the technical feasibility component, focusing on site assessment (data collection, roof and shading analysis, electrical installation, and grid connection) and system performance modelling (layout, installed capacity, irradiation, and Performance Ratio).
In the financial feasibility section, students will gain insight into consumption and production profiles, CAPEX and OPEX, and business case development using indicators such as IRR, NPV, and payback time.
A section on sensitivity and risk analysis explores how variations in key assumptions affect project outcomes.
The building block concludes with a synthesis of key insights and lessons learned, enabling students to apply feasibility study principles to real-world PV projects and contribute effectively to the energy transition.
