At the present time, all country of the world is very interested in renewable energy sources such as solar, wind, geothermal or tidal energy …, solar energy is one of the most energy resource used wide spread. This paper presents a solution to make solar energy more viable, this is increasing the efficiency of the solar panel. The idea is to design a single-axis tracking system, which changes the position of the solar panel for maximizing the incident radiation on panel. Solar tracking system includes solar panel, light sensors, controller and one actuator. In this paper, we present an overview of solar tracking systems, light sensors, introduces the simple controller of the solar tracking systems using platform Arduino uno, present a control algorithm for this system, and conduct modeling of this controller using software Proteus. Simulations results conform to the technical requirements and posed control algorithm. We conducted manufacturing light sensor and controller. Check results show that this controller effective working and have high accuracy.

The article describes the development of use and prospects of bioenergy as one of the drivers of sustainable development as the country as a whole, as well as a separate region. The purpose of research – the possibility of introducing a closed bioenergy developed complex farming Udmurt Republic. For this purpose we developed energy-efficient complex with two bioenergy plants, counted the technological cycle of biogas installation. The amount of heat generated will amount to 465 kW/hour. According to studies it can be concluded about the need to develop renewable sources of energy, especially bioenergy, to move Russia from the fifth to the sixth innovative waves and sustainable development of regional economy.
