Analysis of Peak Power Capacity on Rooftop Solar PV 1.25 kWp at Sun Conditions 90 Degrees

Abstract

This paper describes the optimization of energy conversion when solar radiation occurs at peak power conditions, namely at 11.00 am to 2.00 pm where the position of the sun is parallel to the layout of the PV Rooftop installation. The panels used are 5 units with the type of polycrystalline with a capacity of 1 panel unit consisting of 250 Wp. The position of the panels installed on the roof of the Andalas University building is based on an angle of 90o degrees with a position of ±255m above sea level. The advantages obtained when placed on the roof of the building are due to the minimal impact of shadow effects and environmental disturbances. Data retrieval using DC current and voltage sensors is then connected to the Arduino Uno microcontroller which is then interfaced in graphic form. Considerations in the installation of PV by reviewing the weather conditions at that time where the conditions were sunny and the air was clean with the aim that the performance when solar radiation entered the solar cells could be produced more optimally. Based on the data obtained at peak power, PV can convert DC power to 972.56 Wp. In the final stage of collecting data recorded on this PC, it can later be used as a reference for installing solar panels for household electricity scales in the West Sumatra region.

Energy Generation Intensity (EGI) of Solar Updraft Tower (SUT) Power Plants Relative to CSP Plants and PV Power Plants Using the New Energy Simulator “Aladdin”

“…In addition, it can be used successfully even when the systems do not have a clearly stated electric power capacity. In solar photovoltaic (PV) systems, a peak capacity (at standard test conditions) is available [34][35][36][37]; thus, a power-normalized metric may be used in such cases as kWh/kWp, which means the amount of electric energy generation (in kWh, kilowatt hours) per unit peak capacity power (in kWp, kilowatt peak). However, concentrated solar power systems do not have an equivalent well-defined instantaneous peak capacity power, but they still have well-defined accumulated electric energy generated over one year and a well-defined ground area.…”

Exergy Analysis of Coal-Based 2 X 7 MW Steam Power Plant

“…Once the environment is defined, a value can be assigned to exergy in terms of the property values for the system only, such that exergy can be considered an extensive property of the system [1]- [3]. Exergy analysis is a thermodynamic analysis technique based on the second law of thermodynamics that provides an alternative and enlightening method for rational and meaningful assessment and comparison processes and systems [4], [5]. In particular, exergy analysis yields efficiency, which provides a true measure of how close to ideal performance is, and identifies the causes and locations of thermodynamic losses more clearly than energy analysis [6], [7].…”

Design visual studio based GUI applications on-grid connected rooftop photovoltaic measurement

“…The West Sumatra region has the potential for large-scale solar panel development as well as for household scale. This is influenced by the high potential for solar radiation with an average capacity of 4.8 kWh/m2 per day [14]. However, the frequent occurrence of rotating power outages have a significant impact on activities that occur in the local community such as the Bonjol area where this area does not yet have a main substation and is only supplied by the Bukit Tinggi and West Pasaman substations, even though the weather conditions in the Bonjol area are almost at sunlight reaches 12 hours with hot weather conditions [15].…”
