ПОВИШАВАНЕ НА ПРОИЗВОДИТЕЛНОСТТА НА СЛЪНЧЕВИ ПАНЕЛИ С ПЛОСКИ РЕФЛЕКТОРИ

Abstract

Solar energy is one of the most significant sources of renewable energy both in its fields of application and in thermal and photovoltaic, all over the world. Bulgaria is one of the countries with an excess of this type of energy, where the annual solar activity on a horizontal surface reaches about 1000 kWh / m 2 / year. In this work, solar collectors with a V-shaped trough of a concentrator system with two geometric concentrations are designed to obtain additional electric power. The main results show that the solar concentrator system causes an increase in short circuit current due to an increase in the amount of incident solar radiation from the solar modules and, consequently, an increase in the output power. Compared to the reference module, the increase in power during peak hours exceeds 40%. It can be concluded that the use of a V-Trough concentrating system in combination with modular solar systems can lead to a favorable price-benefit ratio.
