“…Similar dynamic PV systems were fabricated with a-Si PV cells and c-Si PV cells, respectively, in [112], and it was interesting that a-Si PV cells presented higher actual efficiency. According to a study reported in [113], the cost for fixed-tilt PV structures was USD 0.07 per watt output power, USD 0.12 per watt for the adjustable PV structures in one axis and USD 0.40 per watt for the two-axes ones [113].…”

Building integrated photovoltaic (BIPV) technologies are promising and practical for sustainable energy harvesting in buildings. BIPV products are commercially available, but their electrical power outputs in practice are negatively affected by several factors in outdoor environments. Performance improvement of BIPV applications requires mitigation approaches based on an understanding of these factors. A review was, therefore, conducted on this issue in order to providing guidance for practical applications in terms of the selection of proper PV technologies, temperature management, solar irradiation enhancement and avoidance of excessive mechanical strain. First, major types of PV cells used in BIPV applications were comparatively studied in terms of their electrical performances in laboratorial and outdoor environments. Second, temperature elevations were widely reported in outdoor BIPV applications, which may cause efficiency degradation, and the mitigation approaches may include air-flow ventilation, water circulation and utilization of phase change materials. The heat collected from the PV cells may also be further utilized. Third, mechanical strains may be transferred to the integrated PV cells in BIPV applications, and their effects on electrical performance PV cells were also discussed. In addition, the power output of BIPV systems increases with the solar irradiation received by the PV cells, which may be improved in terms of the location, azimuth and tilt of the cells and the transmittance of surface glazing. Suggestions for practical applications and further research opportunities were, therefore, provided.

“…En el caso de los sistemas fotovoltaicos (SFV) es posible la optimización de etapas funcionales, en término de variables independientes, tal es el caso de la irradiancia, potencia recibida por unidad de superficie, y temperatura de los módulos, dando lugar a combinaciones de métodos de optimización [11][12]. En esta área se ha detectado la necesidad de un modelo matemático que incorpore los parámetros del sistema, describa los componentes y su comportamiento, con el objetivo de definir el control dinámico aplicando coeficientes adaptativos, a partir de la identificación de correspondencia entre cada una de los subsistemas.…”

“…Bifacial PV has potential to reach the lowest levelised cost of energy ( LCOE ) of any commercially available PV technology because such bifacial energy gains are achievable using the same land area that is used for monofacial PV designs while maintaining comparable upfront costs [9, 10]. A study by Rodriguez‐Gallegos et al [11] assessed the economics of different PV designs and found that bifacial PV on single‐axis trackers achieves the lowest LCOE for >90% of the world's land area.…”

The energy produced by bifacial photovoltaic (PV) arrays can be augmented via albedo enhancements. However, the value of the additional energy must outweigh the costs for such modifications to be economically viable. In this work, the electrical performance and economic value of six 13 kWp crystalline‐silicon (c‐Si) PV arrays with distinct configurations are evaluated. The system designs include horizontal single axis trackers (HSAT) and 25° fixed‐tilt structures, monofacial and bifacial PV panels, and low and high ground albedo. The value of the system designs is assessed using onsite electrical measurements and spot prices from the Nord Pool electricity market. We find that HSAT systems increase the annual value factor (VF) by 4% and decrease levelized cost of energy (LCOE) by 3.5 EUR/MWh relative to fixed‐tilt systems. The use of bifacial panels can increase the VF by 1% and decrease LCOE by 4.0 EUR/MWh. However, a negligible VF increase and modest LCOE decrease was found in systems with bifacial panels and ground albedo enhancements. Although our results show that albedo enhancements result in lower LCOE than designs without, the uncertainty in upfront and ongoing costs of altering the ground in utility‐scale PV parks makes the solution presently unadvisable.
