Energy Costs Reduce in Energy-Efficient Buildings by Applying Single Axis Solar Tracker

Different ways to increase the energy efficiency of buildings are constantly sought [1–5]. Green electricity use is the perfect logical addition to an energy efficient building. Such electricity can be obtained from sunlight using a photovoltaic panel. Most photovoltaic panels have a CPA approximately 20%, reached at 25°C. It means that at the outlet on the panel surface the transformed electrical energy is maximum 20% of the solar energy. The panel should have a temperature 25°C and be perpendicular to the sun's rays in order to use all of the panel's capabilities. These conditions can be achieved with a sun monitoring system. That publication reveals the creation of such a system.
