Agricultural intensification with Agrivoltaic insect net house systems: Delving into techno-economic feasibility in soilless media Gaurav Gadhiya, Urvashi Patel, Suprava Chakraborty, Pushpendrasingh Chauhan Energy Nexus, 2026 Energy and food are now the two most critical resources for any country. Population growth, industrialization, carbon emissions and food scarcity are all posing major problems to the environment and people. To overcome these difficulties an AV (Agrivoltaic) system which has been an integrated sustainable system is necessary. The AV system is compatible with the UN's SDGs 7, 8 and 13. However, AV might not be suitable for vegetable crops that require accurate pest management since it lacks microclimate control. In proposed work, researchers have developed a new technique for growing capsicum that combines an insect net house and AV. The 1.8 kW AV system has been placed at a height of 3 m to provide optimal tractor movement for various agricultural practices. The total cost of building the AVINH (Agrivoltaic insect net house) structure has been 85300 ₹ (1 ₹=0.012 USD). For experimental purpose, three distinct land treatments have employed utilizing soil and soilless media to cultivate capsicum (shade tolerant crop) in Gujarat. These treatments involved AVINH with covered roof and open roof with open fields serving as three distinct environmental conditions. Remarkably the land equivalent ratio in an AVINH can reach up to 2.55 indicating a significant increase in resource efficiency. It has produced 1058.30 kWh of emission-free energy during the experimental season with 8 years of payback period. This approach may be utilized widely, involving scholars and business professionals to enhance national progress and standard of living.
Performance Assessment of PV Module Technologies for Rooftop and Floating Applications in Southern India Mohamed Rizwan A, Suprava Chakraborty 5th IEEE International Conference on Sustainable Energy and Future Electric Transportation Sefet 2025, 2025 This study compares the performance of rooftop and floating photovoltaic (PV) systems in Southern India for eight different module technologies: monocrystalline silicon (Si Mono), polycrystalline silicon (Si Poly), Heterojunction with Intrinsic Thin layer (HIT), Cadmium Telluride (CdTe), Copper Indium Selenide (CIS), bifacial Si Mono, bifacial Si Poly and bifacial HIT using PVSyst. Analysis is based on energy generation (kWh/kWp/year), performance ratios, and efficiency levels to identify the best performing technology for each deployment scenario. Results reveal that floating PV systems consistently outperform rooftop installations across all technologies, with monocrystalline, polycrystalline, and CdTe modules achieving energy yield improvements of 8–12% in aquatic environments due to enhanced cooling and reduced thermal losses. CIS modules exhibited the highest rooftop performance, yielding 1,653 kWh/kWp/year at an 87.46% performance ratio, while maintaining strong floating system results (1,620 kWh/kWp/year, 86.30%). Bifacial HIT modules demonstrated notable versatility, performing competitively in both environments, with floating configurations leveraging albedo effects for incremental gains. The findings underscore the importance of aligning module selection with installation environments: floating systems offer significant potential for regions with high ambient temperatures, whereas CIS technology emerges as an optimal solution for space-constrained rooftop applications. Bifacial HIT modules provide flexibility for hybrid deployment strategies. These insights equip engineers, developers, and policymakers with evidence-based strategies to optimize solar energy infrastructure and advance sustainable energy goals in tropical climates.
Impact of tilt angle on bifacial power gain of a bifacial solar photovoltaic (PV) module: A comparative study with monofacial (rear side covered) module Achintya Basak, Suprava Chakraborty, Aruna Kumar Behura 2025 IEEE 2nd International Conference on Green Industrial Electronics and Sustainable Technologies Giest 2025, 2025 This study represents a comparative analysis of performance of a monofacial (rear side covered) and bifacial solar photovoltaic (PV) module under different tilt angles such as 0°, $13^{\circ}, 25^{\circ}, 30^{\circ}, 35^{\circ}, 40^{\circ}, 45^{\circ}, 90^{\circ}$ based on power output, and solar radiation. Experimental data were collected for each angle under real operating conditions. Bifacial module shows a consistent increase in performance compared to monofacial module. The highest bifacial gain of 13.20% was observed at 90° tilt angle when rear radiation reached at $174 \mathrm{~W} / \mathrm{m}^{2}$ and measured irradiation ratio was 0.28. The optimum electrical power output of bifacial module of 392.88 W was recorded at 30° tilt angle and in case of monofacial module it was 341.82 W at 35° tilt angle. The findings show that rear radiation and albedo hugely affect the bifacial gain at higher tilt angle whereas optimal power output is achieved at moderate tilt angle in between 30° to 35°. These results signify the importance of adjusting tilt angles in a specific location to maximize the energy output of the bifacial solar PVmodule.
Performance Evaluation of Agrivoltaic Systems: A Comparative Study of HelioScope, PVsyst, and Real-World Data U. R. Patel, G. A. Gadhiya, S. Chakraborty 5th IEEE International Conference on Sustainable Energy and Future Electric Transportation Sefet 2025, 2025 Agrivoltaic (AV) systems, implementation of PV panels into agriculture for food security and climate resilience. Accurate AV energy output simulations are vital for evaluating productivity and guiding decisions for future AV system installations. This study analyzes power generation simulation for a 7.2 kW<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">P</inf> AV structure using HelioScope and PVsyst, comparing simulated performance with actual generation. Results show that both HelioScope (total simulated output: 10199 kWh) and PVsyst (total simulated output: 9860 kWh) underestimated the actual annual energy output of 12667.14 kWh, demonstrating a correlation between expected and actual outputs while also highlighting discrepancies. HelioScope predicted higher energy output than PVsyst, especially during hotter months, but PVsyst's forecasts more closely matched the AV actual performance during peak solar output months. These variances indicate the need for advanced modeling methodologies that integrate real-world AV variables, such as microclimate, ground reflectivity, irrigation intervals and seasonal plant behavior to enhance energy yield prediction accuracy.
Tilt angle optimization for bifacial PV module: Balancing direct and reflected irradiance on white painted ground surfaces Achintya Basak, Suprava Chakraborty, Aruna Kumar Behura Applied Energy, 2025 This study investigates the performance of a 440 W bifacial solar photovoltaic (PV) module installed on the rooftop of the Technology Tower (TT) building at Vellore Institute of Technology (VIT), Vellore. The influence of tilt angle on energy generation was examined by systematically adjusting the module from 0° to 90° during sunny days in February 2024. Measurements were collected at one-hour intervals between 9:00 AM and 5:00 PM. To enhance rear irradiation, the ground beneath the module was painted with white reflective material. Key performance parameters were recorded, and irradiation ratios were calculated for each tilt angle. Results showed a maximum daily average power generation of 316.85 W at a tilt angle of 30°. The corresponding bifacial irradiation ratio ranged from 0.20 to 0.40. Daily average power exhibited a progressive increase from 0° to 30° tilt, followed by a decline to a minimum of 148.51 W at 90°. Interestingly, the irradiation ratio displayed the opposite trend, increasing from 0.32 to 0.96 at 90°. These observations suggest that while overall irradiation reaching the module increases with tilt angle, optimal power generation is achieved at a 30° tilt due to a balance between front and rear irradiance. This study highlights the critical role of tilt angle and ground reflectance when using white paint in maximizing energy output from bifacial PV modules. Within the experimental setup, the PV module's power output remained relatively stable for tilt angles between 13° and 45°, even when considering a 5 % measurement uncertainty. Further investigations are affirmed to explore the impact of seasonal variations and weather conditions on the performance of bifacial modules in this specific geographical location. • Minimal change in power output from PV module for 13°-45° tilt, within 5 % uncertainty. • Near-vertical bifacial modules generate less power but capture more reflected light. • Daytime irradiation ratio increases with tilt angle, stressing reflected light's importance. • Balancing direct and reflected light is key to optimizing bifacial PV power generation. • Tilt angle selection is crucial to maximize energy production from bifacial PV modules.
