“…It can be noted that the variation in percentage of error is due to the irradiation database, where PVsyst has irradiation data from Metronome 7.2 and the irradiation data used in our proposed online PV pre‐sizing tool is from PVGIS software. However, the percentage of error is acceptable whereas a conducted study for 1 MWp using PVGIS and PVsyst in Reference 25, where the authors concluded that there was a deviation around 8%‐15% in output results between the two sizing tools.…”

“…Annual produced energy (APE) across the year depends on which type of selected area, if the area is rooftop or ground mounted system, it is calculated by:

APE = Ps * MGF ((), kWh / year)

where MGF is the monthly generation factor obtained by:

MGF = ([], The monthly irradiation ((), kWh / m^{2} / month)) normalx ([], ξs)

Moreover, if the selected area is industrial shed, a loss of 5.5% is applied due to the change from optimum angle to industrial shed which is obtained by:

APE = ((), Ps * MGF) * 0.945 ((), kWh / year)

The generated energy produced per kWp installed across the year is defined as the specific yield (SY) which can be obtained by:

SY = APE / Ps ((), kWh / kWp / Year)

Additionally, the capacity factor (CF) is determined based on the location selected, the better the localized PV system the higher the capacity factor the more energy captured in daytime for a given PV system components, 25 it can be determined by:

CF = SY / Operating Time (() %)

where the Operating time is the total hours across the year 8760 hours. It is also defined as the maximum energy that can be generated at full rated power for 24 hours/day 26 …”

Summary Photovoltaic (PV) grid‐connected systems have shown a booming trend as a sustainable, green and low cost alternative for providing energy all over the world. Accordingly, PV sizing tools have been promoted to evaluate the expected performance and feasibility of the PV system at a given location. Various commercial as well as free/open‐source PV sizing tool are currently available; however, most of them consider a single prospective, either technical or economic, without considering the location‐based parameters such as the electrical tariffs. The aim of this article is to develop an online free PV pre‐sizing tool for grid‐connected system integrated with tariffs and electricity bills. The proposed tool can be accessed over the internet using multi‐platforms (online), without any charges or subscription (free) and it generates a preliminary techno‐economic solution showed in an online interface and downloadable PDF report (pre‐sizing). Seeking for validation, various 24 case studies have been conducted over four different cities in Egypt, where a commercial tool has been utilized as a bench mark. An overall mismatching error various in the range of 1% to 6% has been recorded, showing the full appropriately of the developed tool. Finally, a level of satisfaction questionnaire has been operated among various user segments, where acceptable outcomes have been observed.

The paper presents a performance investigation of a 3-kW grid interactive photovoltaic system located at Eskişehir Technical University using PVSYST program. The system has 260 , 12 PV modules and is connected to a 3-kW inverter. Parameters like the energy from PV panels, energy fed to the utility grid, performance ratio and final yield per installed is presented. The system produces 4839 kWh/year and injects 4648 kWh/year into the utility grid. It has a performance ratio of 84.8% and the specific production of 4.08 kWh/ /day. The specific production is compared to other systems in the literature review around the world. The paper concludes that Eskişehir region has a better solar energy potential than most places in Europe but not as good as the solar PV systems located in Africa or Asia.

Five 3.25-kWp Photovoltaic Systems were installed in different regions in Peru. Solar irradiance and power output were measured during the entire year of 2019. Based on data registered, solar photovoltaic (PV) performance ratio was assessed for all systems. Analysis of how a variation of the solar irradiation and the power output may affect Levelized Cost Of Energy (LCOE) values was carried out. Implications for end users in terms of expected payback time due to different LCOE values were also assessed. It is concluded that Performance Ratio changes over the year depending on which of the five regions the PV system was installed. Considering average monthly values, calculated for over a year, the highest value corresponds to Site Number 3 (Piura) while the lowest value corresponds to Site Number 2 (Lima Agrarian National University La Molina, UNALM). If LCOE from site Number 3 is considered as a basis for comparison purposes, then LCOE from site Number 2 would be 78.5% more expensive in terms of US$/kWh. Also, if payback time from site Number 3 is considered as a basis for comparison purposes, then payback time from site Number 2 would be 78.5% longer. Therefore, expected performance of a solar PV system, among different regions of the country, is a factor that should be considered when proposing policies and incentives for net metering squemes under distributed generation.
