The teaching unit "Project Development of a Photovoltaic System" introduces students to the planning of a real solar project. The unit can be conducted as a standalone lesson or serve as the starting point for a further school-wide project in which the plan is subsequently implemented.
 

 
 The class takes on the role of a project team tasked with developing a photovoltaic system for their school. Together, the students analyze potential locations for the system, discuss the school's electricity needs, and consider the optimal size for the installation. They also examine fundamental questions regarding economic viability, CO₂ savings, and organizational requirements such as permits and financing.
 

 
 Another component of the lesson is the examination of the role of petitions in democratic decision-making processes. Students learn about the function of petitions in politics and how they can be used as a constructive expression of civic interests. As an example, a petition is prepared at the school, aiming to initiate the installation of a photovoltaic system on the school roof. In doing so, the students reflect on potential challenges involved in formulating demands, gathering support, and communicating with decision-makers.
 

 
 The lesson thus provides a basic understanding of how a solar project comes about – from the idea to its implementation – and how young people can use democratic instruments to initiate change.
