Experimental studies and comparative analysis of load-bearing structures with photovoltaic elements
https://doi.org/10.15518/isjaee.2024.05.012-020
Abstract
The work is devoted to experimental studies of a new type of building products: load-bearing panels with integrated photovoltaic cells. Technical solutions are protected by patents of the Russian Federation for the invention. Photovoltaic cells are placed on the inner surfaces of the cells that make up the power circuit of the supporting structure of the panel.
The purpose of the experiment is to identify qualitative and quantitative differences between new panels relative to panels with controlled and fixed relative to the sun position of photovoltaic cells. The developed technique involves varying the position of the photovoltaic cell to simulate operation under the conditions being compared.
An assessment of the energy contribution of a photovoltaic cell is performed, as which the short-circuit current is taken into account during comparative tests. When processing the obtained data, a high degree of suitability was shown by factor analysis: KMO = 0,81, p <0.001. Two factors were identified: diffuse illumination (0,62 dispersion); azimuth factor (0,17 dispersion). Studies of operation in conditions of partial and full shading have been carried out, comparative quantitative estimates of the energy contribution of the new panel relative to solar-flow-oriented structures have been given.
The energy contribution of the cell according to the criterion of equivalent area in comparison with a controlled solar cell is 0,9-2,5, depending on the azimuth. With respect to fixed panels 2-4 times.
