  • Course details

With the current downward price in the development for photovoltaic (PV) projects, there is an increased interest in installing PV systems. Newly-installed peak power of PV now surpasses all other technologies, both conventional/fossil-based technologies as well as renewable technologies.

With this training course, you will learn how to implement projects using one of the most promising energy technologies currently available. You will acquire a solid theoretical and foundational understanding of PV project management, combined with practical hands-on exercises. Our experienced trainers will get you involved in the training and will facilitate valuable group interactions and discussions.


  • Photovoltaic markets and technical introduction
  • Management of solar projects (with case studies)
  • Economics and financing of PV projects (with case studies)

Training Course Objectives:

  • Evaluate the bankability of PV projects;
  • discuss technical, commercial, legal, and political risks as well as risk mitigation schemes;
  • determine CAPEX/OPEX, assess key financial indicators, and set up the financial structure of PV projects;
  • debate the advantages and challenges of PV power plant economics;
  • provide the knowledge and tools to make informed decisions on PV projects; and
  • facilitate the exchange of potential or specific project ideas among participants, who bring perspectives from around the globe.

Learning Objectives:

  • identify PV market development, segments, and outlooks;
  • describe the main components of a PV system and use software to access meteorological data estimates and forecast PV system yields;
  • define project phases, starting with the initial concept to operation and maintenance, to developing PV project plans, including: planning and commissioning, approvals, logistics, construction, and grid-connection;
  • implement, coordinate, and control PV projects from the installation process to grid-connection;
  • identify project risks, risk mitigation, and dos and don’ts;
  • analyse operational data from a real PV system;
  • evaluate the core activities within the PV value chain;
  • assess main steps of project development and implementation;
  • understand key stakeholders’ roles and project structures;
  • assess the KPIs of PV project calculation;
  • investigate main costs (CAPEX and OPEX) and other relevant figures for an economic analysis; identify leverage of projects; and evaluate a project with an accompanying economic efficiency calculation tool

This training will suit those who:

  • have prior knowledge of PV technology, and you are interested in implementing projects and need a comprehensive overview on PV project economics and finance
  • are a project developer, project manager, engineer, quality inspector, or customer service professional in the solar energy industry and want to start evaluating/developing your first project(s).

Dr. Emilienne Tingwey, RENAC

Current position:

Emilienne Tingwey joined the Renewables Academy (RENAC) AG in Berlin in 2010 and started off as a project assistant in the international know-how transfer project TREE (Transfer Renewable Energy & Efficiency). After managing various tailor-made courses offered by RENAC and carrying out solar training exercises, she is presently the project director of all face-to face training programmes at RENAC. She is head of the Green Energy Summer School, an annual study event offered by RENAC.

Professional experience:

Emilienne is a certified TüV trainer and trains people on how to carry out renewable energy training seminars and helps others to develop training programmes in renewable energy.Additionally, she is really keen to empower women and youth in the RE sector through training. With RENAC she carried out the APEC project ‘Empowering women as managers of the Renewable Energy‘ on behalf of the United States Department of Energy. Through training and mentoring, the project helped to increase the contribution of women to RE development in APEC economies. She was also in charge of a GIZ sponsored project in Cameroon: Transfer of renewable energy knowledge through the usage of solar photovoltaic to provide energy (electricity) to a local health centre: an off-grid system was installed in a local health centre and thereby training some youth in the community.
