System of photovoltaic solar electric power for buildings: “solar facade with variation of the β-angle”

Abstract

Based on a previous work, this paper presents a system for the use of photovoltaic solar energy for the facades (vertical claddings) of the buildings, applied to a specific modern building. The system presents regulation to one axis, which will vary the ß-angle (the or inclination of the solar cells) in order to be placed in the most perpendicular possible way to the solar radiation. This particular application is based on optimization algorithms developed for the supervision, control, and management of photovoltaic solar electric power in singular buildings dedicated mainly to apartments. The basic principles of performance of these algorithms are kept within two big guidelines: renewable energy generation (to produce so much electric solar energy as possible), and demand side management (to reduce the demand peaks of the buildings). The presented system is integrated in the buildings in order to present a particular aesthetic appearance. Then the algorithms and procedures of the system are designed in combination with the information of the different commercial solar panels in the market.
