“…These statistics show that educational institutions are among the highest energy users compared to other public buildings. Research focusing on the potential of installing solar PV systems in educational buildings to reduce energy consumption and electricity bills leads to positive significance, as mentioned by [7]. The present work by Oleiwi et al [8] uses a simulation PV system and Green Power Solution to suggest installing it on the roofs of educational facilities in Baghdad; the results show that an on-grid connection is the most suited PV system.…”

The education sector is one of the contributors to greenhouse gas emissions. Therefore, the education sector strongly supports the government’s aspirations to reduce carbon emissions. Energy consumption is related to the amount of carbon emission production—energy consumption information helps to forecast energy savings while creating carbon emission reduction. The research aims to propose a new modeling of rooftop solar photovoltaic (PV) by installing the Net Energy Metering (NEM) meter in the Politeknik Sultan Azlan Shah (PSAS) educational institution's ring distribution system. The energy demand at PSAS in 2022 is 3,916,534 kWh/year, equivalent to an energy cost of RM 1,429,535. The new model design is based on setting 20% of the total power supply in PSAS generated by solar. A feasibility analysis on the proposed modification of the distribution layout design found that in the next four years, it is predicted that the minimum energy savings that PSAS will obtain are 2,075,763 kWh, while the annual bill savings are RM 757,654. This energy saving leads to a reduction in gas emissions where PSAS can reduce the production of 1,526,620 kg of CO2 to the environment while saving 38,165 mature trees from being cut down.

“…Extending the foundations laid by prior studies on PV system design and techno-economic analysis, particularly within university contexts and equatorial regions, this research pioneers optimal grid-connected rooftop PV systems for universities (Mokhtara et al, 2021). Building upon optimal sizing insights (Khairi et al, 2022) and financial viability revelations (Shabbir et al, 2022), this study amalgamates the knowledge gleaned from Padang's equatorial characteristics. In doing so, the research endeavors to offer a comprehensive comprehension of the prime design and techno-economic facets of rooftop PV installations in the distinct equatorial milieu of a university campus.…”

Through a thorough analysis using Net Present Cost (NPC) over a 20-year period, this research presents a comprehensive and economically optimized solar panel design methodology. The study examines two different PV system configurations: On-Grid PV and Off-Grid PV, using sophisticated simulation and analytical techniques with the aid of HOMER Pro software. The simulation results offer compelling new information about these systems' economic viability. The simulation results in an NPC value of IDR 31,386,360,- for the Off-Grid PV configuration. The On-Grid PV system, in contrast, exhibits a significantly lower NPC value of IDR 8,903,329,- emphasizing its superior economic performance. This On-Grid PV system boasts a significant energy generation capacity of 5,012 kWh/year in addition to favorable cost efficiency. Notably, this is greater than the National Power Company's 1,186 kWh/year energy output. These results highlight the financial benefits of the On-Grid PV system and demonstrate its capability to provide affordable and sustainable energy solutions over a long period. The thorough analysis carried out in this study aids in the optimization of solar panel designs, offers insightful information for future sustainable energy projects, and emphasizes the crucial part that economic factors play in influencing the adoption of renewable energy technologies.

Climate change is a global issue that requires collective action to address. One of the most pressing concerns is reducing emissions resulting from combustion processes. The use of renewable energy sources and green energy has become a trend worldwide. Solar energy is one of the most promising sources due to its abundance and simplicity of implementation. The city of Aswan, located in the South of Egypt, has a high solar radiation that makes it ideal for utilizing solar power. The current study investigates the optimal design for a sustainable building electricity system at the Aswan Campus of the Arab Academy for Science, Technology & Maritime Transport (AASTMT) in Egypt. The campus has four electricity sources: a utility grid, PV panels, batteries, and a diesel generator, along with a weather station. Experimental investigations have been carried out in this research paper to study the performance characteristics of solar power. Moreover, HOMER pro software is used to model various configurations of the campus grid, including different photovoltaic (PV) panel types and tracking systems. The simulations are compared with real-world data collected from a weather station on campus. Additionally, CO2 and NO2 emissions are measured to assess the environmental impact of different scenarios. The total net cost over the life cycle is also calculated for different cases. The results demonstrate that the addition of a PV renewable system can reduce traditional grid usage by 38% and emissions by 50%. A decrease in the Levelized Cost of Energy (LOCE) from USD 0.0647 to USD 0.0535 is reported. Moreover, the difference in NCP cost between dual-axis tracking and fixed zero angle is USD 143,488. The dual degree tracker for PV panels can further enhance energy production by 30% more, compared with fixed panels, while reducing carbon dioxide emissions by more than 20%. The simulation results reveal that tracking systems provide greater energy generation, and that a cost–benefit analysis may prioritize fixed panels in some cases. The results from the HOMER software simulations closely match those of the experimental data, which is that the total presentation error does not exceed 8%, demonstrating the software’s effectiveness for optimizing renewable energy systems. This study demonstrates that a comprehensive analysis and optimization of a building’s energy sources can significantly reduce costs, lower emissions, and promote the use of renewable energy, particularly solar power.
