Geometric Modelling of Low Concentrating Photovoltaic System
Author:
Abstract: The paper presents aspect to increasing energy production of photovoltaic systems by concentrating solar radiation and orientation of photovoltaic modules. To focus sunlight on photovoltaic surface and increasing thus the energy absorbed, the concentration solar photovoltaic systems used either optical elements retractable (usually Fresnel lens) or reflective elements (usually mirrors). The photovoltaic concentrating system aims to reduce expenses regarding photovoltaic surface and replace it with optical materials. Geometric design issues are presented for these systems adapted to the conditions of a certain geographical location. The paper started with modeling of specific angles of photovoltaic panel and ends with a prototype of low concentrating photovoltaic system (LCPV). The simulation results show that the additional length decreases with the angle formed between the mirror and photovoltaic module x, and increases with the incidence angle h, meaning with the duration of the orientation step. Also, the concentration ratio increases with the increase of angle x. In order do not overweight the supporting structure of the LCPV system there have been utilized materials with light weight.
