“…From an environmental perspective, if a photovoltaic system is installed on a heavily shaded roof, the power generation during its life cycle cannot offset the energy consumed during the production process, and the emission reduction during its life cycle may be negative. Therefore, it is necessary to calculate and analyze the annual cumulative radiation amount required for the photovoltaic system to balance the power generation income and initial investment during its life cycle, that is, the economic radiation intensity of solar photovoltaics [9,11,22,23]. In this paper, the economical photovoltaic installation ratio is selected as the index to evaluate the potential of photovoltaic installation capacity in the area, as shown in the following formula:…”

“…It is also proved that increasing the number of photovoltaics can reduce primary fossil energy use and global energy costs [6]. According to the analysis of the annual energy structure, 29% to 75% of the annual power generation of distributed photovoltaics can be used for self-consumption, which shows the huge potential of distributed photovoltaics in achieving the goal of carbon neutrality [7][8][9][10][11]. However, the shading effect between buildings and mismatch between the solar power generation and building energy consumption often limit the application of the distributed photovoltaic system.…”

The large-scale application of distributed photovoltaic system is often impeded by the shading effect between buildings and mismatch between the solar power generation and building energy consumption. This paper explores the relationship between urban form and rooftop photovoltaic installation and utilization potential with implications for low-carbon city planning. This study first investigated the influence of the urban form on the installation potential of the solar rooftop photovoltaics for 12 cities across China which covering different solar climate zones. The significant impact of the urban density on the photovoltaic installation potential is only observed in the cities in high latitude areas with medium solar radiation, and the negative impact can be mitigated by reducing the building height differences, which up to 25% improvement can be expected. Then, taking Shenzhen as an example, the influence of the urban form on the photovoltaic power generation utilization was further investigated for residential, commercial and office type of district building energy consumption profiles. It is found that the densely developed urban built-up environment has positive effect on the solar power utilization in which high percentage of the self-consumption ratio is observed. The self-consumption ratio of the residential district which is the lowest can be effectively improved by mixing with office and business buildings. For typical urban form in Shenzhen which the BCR and FAR are 0.35 and 2.5 respectively, if carefully planned, the rooftop photovoltaics can provide 12.6~18.5% of the building energy consumption and 69.8~75% of the solar power can be directly used by the building, which make the rooftop photovoltaics an important clean and economical energy resource for low-carbon city development.

“…Specifically, the proposed model makes use of Magni's (2020) [6] accounting-and-finance system to engineering economic decisions. It accomplishes a detailed analysis of the sources of value creation in both absolute and relative terms, always supplying the net present value (NPV), the rate of return, and the financial efficiency, thereby overcoming the limitations of the internal rate of return (IRR), usually recommended in benefit-cost analysis (Sartori et al 2014 [10], Mangiante et al 2020 [9]), but most likely to be undetermined in this kind of projects.…”

The adoption of a photovoltaic system has positive environmental effects, but the main driver of the choice in the industrial and commercial sector is economic profitability. Switching from acquisition of energy to production of energy is an investment with costs (e.g. leasing annual payment, O&M costs, capital expenditure) and benefits (e.g. savings in the electric bill, sale of the energy exceeding consumptions). In this work, we use an accounting-and-finance model to calculate the Equity Net Present Value in different scenarios and a sensitivity-analysis method (Finite Change Sensitivity Index) to explain the reasons for differences in results. This technique enables identifying the contribution of any input factor in the output value variation. In this way, the investor can draw attention on the most significant critical variables in the initial estimations to ensure success in forecasting.

“…Selain itu, pemerintah juga berfokus pada pembangunan ekonomi sesuai SDGs yaitu tercapainya pertumbuhan ekonomi berkualitas melalui keberlanjutan peluang kerja dan usaha, inovasi, industri inklusif, infrastruktur memadai, energi bersih yang terjangkau dan didukung kemitraan [SDGs]. Namun untuk merealisasikan energi bersih khususnya melalui PLTS on-grid perlu dilakukan analisis desain yang matang sehingga penggunaannya dapat optimal dan sesuai dengan target yang ditetapkan [7][8][9][10][11]. Beberapa studi telah mengkaji desain yang optimal pada perancangan PV on-grid namun tanpa menggunakan baterai [12].…”

This paper aims to investigate the feasibility and viability of the on-grid solar power generation at the university canteen by using two alternative methods. The first method uses the actual daily load as the basis of the calculation for the reliability of the system, whilst, the second method uses the available area as the basis of the calculation of the power generation. This research analyses the technical feasibility and the economic viability of each possible configuration involved in the comparison process. The analysis shows that the on-grid configuration set by using the maximum available area for power generation provides the highest economic viability. The system may contribute to nearly 68.98% of the working day energy consumption and nearly 182.18% of the consumption during the weekend. The total energy generation is expected to reach the potential of 16.063kWh annually.
