Optimization of building integrated photovoltaic systems

Abstract

The low irradiance efficiency of photovoltaic modules is important to the optimization of Building Integrated Photovoltaic (BIPV) systems. BlPV arrays are often not facing south and are frequently mounted vertically. Under these conditions, a greater portion of the total sunlight striking the array is diffuse, which is of lower intensity than direct sunlight.A lkWp, grid connected array of PV modules was used for assessing the accuracy of an energy performance model developed for BlPV systems. The algorithm for calculating power output of the photovoltaic array is derived from the ideal diode equation. An empirically derived parameter modifies the equation and the resulting model can be used to predict the performance of a variety of PV cell technologies at all irradiance levels.

Prototype development of smart parking system powered by solar photovoltaic

“…In [5] author write photovoltaic(PV) panels that use solar energy are used in lots of domestic and commercial houses, such as public parking garages, commercial centers, hypermarkets, and sub-urban apartments. In [6] author writes if photovoltaic technology is merged into design in building, it should consider the PV system technology.…”

“…In [7] proposes an efficient and robust maximum power point tracking based charge controller, a design and implementation of a low cost, suited for stand-alone or backup PV applications. At present, building integrated photovoltaic system can be divided into two classes; roof structure photovoltaic system and wall structure photovoltaic system [5].…”

Review of Economic Operation Optimization Strategy of Photovoltaic Grid-Connected System

“…Economic operation optimization of photovoltaic grid-connected system is to achieve the minimum cost of generation and the maximum income of operating. The economic operation of PV grid-connected system is a discrete, nonlinear optimization problem with multi variables [3]. The main research contents include the element operation model, network model, objective function, constraints and optimization strategy and algorithm.…”

Investigation of grid-connected photovoltaic generation system applied for Urban Rail Transit energy-savings

“…Solar roof plans are implementing in more and more countries or regions [2]- [6]. Referring to application results of PV generation systems [6]- [9], it can be easy to find that the urban rail transit (URT) has good applied conditions for PV generation system, such as huge arc roof of the open station with wall, and sound barriers along the line etc, where PV cells which do not take up extra space can be installed as a decorative in a unified appearance. In addition, the two sides of the elevated lines can provide very large installation space for PV cells.…”
