6 Enrollments Level : IntermediateRelevance
In the context of global climate goals and increasing energy demand, solar energy has become a cornerstone of sustainable development strategies. Rooftop photovoltaic (PV) systems, in particular, offer a decentralized, scalable, and cost-effective solution for clean electricity generation. Their relevance continues to grow as building-integrated energy systems become more prevalent and regulatory frameworks increasingly support self-consumption and grid interaction.
Understanding how rooftop PV systems are designed, installed, and maintained is essential for professionals involved in energy, construction, and sustainability sectors. This building block provides the foundational knowledge and practical insights needed to actively contribute to the successful deployment and operation of rooftop PV systems.
Abstract
sustainability goals. It begins by explaining the importance of solar energy as a key technology for decarbonizing the energy sector, increasing energy independence, and supporting the transition to a low-carbon economy.
Following this contextual introduction, a real-world case study is used to illustrate the full lifecycle of a rooftop PV project. Each phase is addressed in detail, from feasibility assessment and administrative procedures, through system design, tendering, and construction, to commissioning and performance evaluation.
Students will gain a thorough understanding of the technical components of rooftop PV systems, including modules, inverters, mounting structures, and electrical connections, as well as key aspects of operations and maintenance (O&M) and troubleshooting practices.
The building block concludes with an analysis of the economic and environmental impact of the system and a reflection on lessons learned. By combining strategic context with practical application, it equips students with the knowledge and tools needed to contribute effectively to the deployment of rooftop PV systems as part of the energy transition.
