“…Inverters are used in different types of solar systems to match the generated energy of the PV panels with the electrical grid (Yilmaz & Özçalik, 2015). Inverters use different technologies to convert DC energy, produced from PV cells, into AC (De Lima, De Araújo Ferreira, & De Lima Morais, 2017), (Kymakis, Kalykakis, & Papazoglou, 2009).…”

The Egyptian government has set renewable energy targets of 20% of the electricity mix by 2022 and 42% by 2035. The National Water Research Center (NWRC) (Qanatir, Egypt) set up a pilot rooftop 90 kW PV system supporting this approach. This paper analyzes the electrical output signals of 90 kW photovoltaics on-grid system mounted on the roof of the National Water Research Center (NWRC) (Qanatir, Egypt). A previous simulation model using Matlab program is modified to incorporate more accurate information on system configuration became available. Components of the model were modified: four inverters (20 kW rated power) and one (10 kW rated power) and the scenario of tying the system to the local low voltage grid is discarded. Recommendation from previous study was taken to tie system the national high voltage grid to multiply the savings; therefore, it is the only simulated scenario.The simulated output energy of the system, at different values of solar intensity, is compared with the recorded data. A deviation between the simulink model and recorded data is found, due to power failure, surface cleaning of PV panels and weather variations. The results showed that the maximum energy is generated during July (14.5 MWhr) whilst the minimum energy in December and January (5 MWhr).

In this research paper effect of pandemic and performance analysis of the utility grid connected PV system under net metering is evaluated for one years based on PV plant generation data. The performance of the system depends on annual average final yield, reference yield, and array yield and their values are 3.87 kWh kWp-1. d-1, 4.57 kWh kWp-1. d-1, and 4.29 7kWh kWp-1d-1 the performance ratio and capacity utilization factor are 77.48% and 15.68%. Due to pandemic campus energy consumption is less so energy export to grid is more than the energy import from grid. As per the state energy policy minimum billing is done even the export units are more than the imported units which result in increase in return on investment (ROI) compared to post pandemic. The above statistics illustrate the quite strong performance of solar power plants built in the Indian state of the Andhra Pradesh, Guntur.

“…Even though the interest in PV applications has been increasing, no studies have been carried out to determine the losses caused by snowfall which reduces power generation. In the current performance studies, performance losses caused by snowfall are not included in the assessments [14,15]. Therefore, a snowy region (Konya, Turkey) which is prioritized in PV solar energy investments has been chosen as a working area to resolve this research deficiency.…”

When the module surface is covered with various factors such as snow and icing which prevent the solar irradiance from reaching the photovoltaic cells, the power production of the system and its performance decrease. The purpose of this study is to determine the energy production losses of a grid-connected photovoltaic plant due to snowfall and icing. The effect of snowfall and icing has been examined on a photovoltaic system consisting of a hybrid inverter with two separate maximum power point tracking inputs and 36 monocrystalline modules, which are mounted on the supporting system horizontally in the south direction and at a constant tilt angle of 30 • . The plant area is located in a priority and snowy region (Konya,Turkey) where large-scale photovoltaic system installations are carried out. In order to evaluate the effect of snowfall, the minute resolution data of the hybrid inverter which provides connection to the grid is used. The change over time of the power generated by the two arrays of the plant was examined comparatively. For comparison, one of the arrays was continuously cleared. The recorded data was used to determine the expected energy output of the array covered with snow. Besides, the solar irradiance and ambient temperature data obtained from the meteorological station were used to accurately identify and evaluate the effects of snowfall with digital images recorded in the site area.The results showed that surface clearing of modules had a significant positive effect on the power output of the system. In the array entirely covered with snow, the daily energy loss exceeds 93%. In months of heavy snowfall, the monthly energy loss is 18% depending on time of being covered with snow of the modules. When the production data of 2017 and 2018 is evaluated, it is seen that the total energy loss of the plant varies between 1% and 2%.
