Improving solar photovoltaic installation energy yield using bifacial modules and tracking systems: An analytical approach

Abstract

In this paper, we present the results of a simulation of a 3 MWp photovoltaic plant in Nigeria using four case study scenarios: ground-mounted fixed inclined monofacial, and bifacial photovoltaic installation, as well as monofacial and bifacial photovoltaic installations with trackers. The bifacial gains, tracker gains, and bifacial-tracker gains were calculated for each configuration. The fixed ground-mounted inclined bifacial PV system gained 12% annual average bifacial gain over a fixed ground-mounted monofacial system, while the bifacial system with a solar tracker gained 8.9% over a monofacial system with a solar tracker. A monofacial PV system with a tracker over a fixed inclined monofacial system has a tracker gain of 16%, while a bifacial PV system with a tracker over a fixed inclined bifacial system has a tracker gain of 13.2%. The monofacial system with a solar tracker outperforms a fixed inclined bifacial system by about 4%. The sensitivity analysis performed to determine the effect of system parameters such as albedo and ground clearance height on bifacial PV systems reveals that the increase in specific energy production per kilowatt-hour per year is directly proportional to the albedo of the surface area on which the bifacial PV systems are installed, and adequate ground clearance height is required between the ground and the installed bifacial PV plants.

Design of actuator motor acceleration model in dual axis tracker movement for stand-alone PV system

“…Previously, a projection method was carried out using the PV position in flat conditions or at one point on the solar cell where this condition has not been able to produce optimal energy conversion in converting [18]- [21]. Then another problem that occurs is weather fluctuations that occur such as the movement of clouds in covering the sun so that the conversion produced by solar cells into electrical energy drops dramatically [22]- [24]. The solution is to focus on increasing the development and installation of a stand-alone PV system with the concept of using actuator motor technology with two linear motor drives so that the power generated by PV is maximized.…”

Performance Analysis of a 50 MW Solar PV Installation at BUI Power Authority: A Comparative Study Between Sunny and Overcast Days

“…This hybrid setup aims to improve energy stability, optimize resource utilization, and contribute to the national grid while minimizing environmental impact [26], [27]. The performance of solar PV systems is highly dependent on weather conditions, specifically sunlight availability, solar irradiance, ambient temperature, and system design [28], [29], [30], [31].…”

Study of bifacial photovoltaics with fluorinated ethylene propylene as an anti-reflective layer

“…One of the approaches involves the use of lightguides or reflective meshes in the intermediary spaces between the PV cells to reduce and redirect stray light back onto the cells [2,3]. Another method via which the efficiency of such systems can further be enhanced is through the external arrangement of the reflecting ground surface such as grass, sand cement etc [4,5]. In contrast, the method investigated in this work involves material substitution and changes in the layer arrangement of the bifacial panel structure for improved performance.…”
