Abstract Background End energy user relies on fossil fuel-based national grid to meet their energy demand; hence, indirectly contributing towards greenhouse gases (GHG) emission and causing climate change. This study aims to investigate the minute role of a single, end energy user in GHG mitigation by shifting to the green renewable energy source, photovoltaics (PV) through its techno-economic analysis. Method For the study impact, NASA Meteorological Data is used to select an ideal single energy user equipped with 10 kW PV system based on annual- average daily solar radiations and temperature through MATLAB/Simulink, among eleven populous cities of Pakistan. Helioscope software is used to select tilt and azimuthal angle to expose PV surface for most of the solar radiations. Afterwards, RETScreen software is used for cost, financial and GHG analysis. Results and Conclusion The proposed system at single end energy user mitigates 6.9 tonnes of CO2 per annum while producing 16,832 kWh per annum and recovering its 7337$ capital cost in less than five years in the project’s 25-year life span. A single energy user invisible to national grid can play a pivotal role in GHG mitigations while earning from its investment and achieving energy independency from the main grid at the same time.

Energy Demands

Abstract Background Households, as end energy users, consume grid electricity to meet their energy demands. However, grids across the globe for energy production are majorly based on fossil fuel technology and make the highest contributions to global warming and climate change due to greenhouse gases (GHG) emissions. This generic study aims to investigate the minute role of a single-end energy consumer in GHG mitigation by switching to a rooftop PV system to meet his energy demands and trading surplus energy to the grid through its techno-economic analysis. Method For the study impact, NASA Meteorological Data are used to select an ideal single energy user equipped with a 10-kW PV system based on annual average daily solar radiation and ambient temperature through MATLAB/Simulink, for 11 populous cities in Pakistan. Helioscope software is used to select tilt and azimuthal angles to maximize the solar radiation intercept. Afterward, RETScreen software is used for cost, financial and GHG analysis. Result and conclusion A single end energy user equipped with a 10-kW PV system switched to a green energy source from a fossil fuel-based grid has the potential to avoid the burning of 3570.6 L of gasoline by producing 16,832 kWh of green energy per annum, while financially recovering the 10-kW PV system’s 7337$ grid-tied investment in 5 years (equity) and in 9 years (equity) in a 9077$ stand-alone system over its 25-year life. This approach provides relief to end energy users from high priced grid electricity through environmental friendliness by mitigating 8.3 tons of CO2 equivalent emissions per annum from energy production, while providing relief to the main grid by grid stabilization through peak shaving, in the broad sense.

End energy user is dependent on fossil fuel-based main-grid and contributes toward greenhouse gasses (GHG) emissions. Changing its energy source will change the dynamics of the power plant, contribution towards GHG production. This case study aims to highlight the minute but positive role of a single end energy user, invisible to the main grid in GHG mitigations through photovoltaic energy source, selected among Pakistan’s top 10 most populous cities as per census 2017. Quetta is a selected city in Pakistan as the best fit location based on annual average daily solar radiations (AADSR) data retrieved from National Aeronautics and Space Administration (NASA) meteorological data. Helioscope software is used to select −15° tilt and 180° azimuthal angles, which further increased Quetta’s AADSR value from 5.54 kWh/m2/d to 5.93 kWh/m2/d. For research significance, a realistic approach is undertaken by proper selection of solar panel type based on Quetta’s annual average temperature, load categorization, user selection and inputs from a solar energy expert. Finally, initial cost, investment and GHG mitigation analysis are carried out in RETScreen Expert software, which validates the minute but the prominent role of a single, end energy user by mitigating 122 tons of CO2 in 25-year project life span. Further, the proposed project favors end-user financially by recovering its $4501 initial cost in less than four years by effectively meeting its energy demand and saving $1195 per annum.

Pv Systems

Green energy by PV systems reduces the dependence on fossil fuel-based power plants. Maximizing green energy to meet the demand reduces the burden on conventional power plants, hence lesser burning and greenhouse gases (GHG) emissions. For this purpose, this study draws a relationship between tracking schemes of the PV systems to GHG mitigation potential. The best fit location for detailed analyses is selected among the 15 most populous cities of Australia. The solar radiation potential is increased to 7.78 kWh/m2/d through dual axes tracking compared to 7.54, 6.82, 5.94, 5.73 kWh/m2/d through the one axis, azimuth based, fixed-tilted, and fixed-horizontal surface schemes, respectively. Through the dual axes tracking scheme, a 1 MW PV system per annum energy output avoids the burning of 796,065.3 L of gasoline, 4308.7 barrels of crude oil which is equal to the mitigation of 1852.7 tCO2 equivalent GHGs. Concisely, the PV system, through its green energy output, can avoid the release of greenhouse gases from fossil-fuel plants to tackle climate change more effectively.

This paper proposes design steps in obtaining the optimal size of a standalone photovoltaic (PV) system, which is able to meet a predetermined power load requirement. The keys of the system sizing are primarily to satisfy a specific load demand that depends on the power generated from the installed PV system and also to maintain hydrogen storage state of charge. A case study was conducted using Kuala Lumpur's meteorological data and a typical rural area load profile of 2.215 kWh. An economic analysis on the system was performed in order to determine system feasibility. The levelized cost of energy for the proposed system was RM1.98/kWh. However, the results showed that if the same configuration used absorbent glass mat (AGM) battery as the backup power supply, the system cost and levelized cost of energy is lower. Therefore, a sensitivity analysis of the electrolyzer and fuel cell efficiencies towards levelized cost of energy for the proposed system was executed. The result indicates that unless the efficiency of hydrogen storage technologies significantly increases in the future, the system will not be feasible to be implemented in Malaysia.
