Modelling Approach
and Results
The modelling part is crucial to designing the suitable renewable system
by estimating the demand characteristics associated with generation potential.
PVsyst is a widely used software tool for modelling the performance of photovoltaic (PV) systems due to simplicity, less complexity and ease of learning than that of other software, ease of accessibility, accuracy, allows for proper calculation of load values and more
choose the geographical location.

Site Location
After selecting the location of the representative site that is also associated. The next step was to collect the site data, including the latitude, longitude, altitude, temperature, solar radiation, wind speed, and other climate data that are needed to run the simulation. This data was obtained from online databases sources built in the software.
2. PV system orientation
PVsyst showing optimization of system orientation only for fixed tilt plane is studied. The tilt angle is the angle of inclination of the system. This depends on the geographic location. The tilt angle must be in such a way that the system yields maximum output. The panels are facing south tilted with 40° as shown in Figure.
3. User demand
In the daily profile editor, the user can input the hourly energy consumption values for each month of the year. The values can be entered manually or copy and paste them from a spreadsheet or other source. The hourly profile was then depicted in graph.
4. PV system components selection

Selection of PV Module
Trina Solar was chosen for its exceptional customer value, which stems from its high-power output of up to 555W and impressive efficiency rating of 21.2%. Additionally, the company boasts a high level of reliability thanks to its innovative non-destructive cutting technology, which minimizes the occurrence of micro-cracks. Furthermore, Trina Solar's panels have demonstrated a remarkable ability to generate energy even under low radiation conditions, resulting in a high energy yield overall.
Inverter selection
Gin long Technologies inverter was selected because of its high efficiency, durability and reliability. Gin long Technologies inverters are known for their high efficiency, which means that they can convert a larger percentage of the DC power generated by your solar panels into usable AC power. This can result in a higher overall energy yield and lower energy costs. The inverters are designed to withstand harsh environmental conditions, such as extreme temperatures and humidity. Additionally, they are equipped with advanced safety features to protect against overvoltage, overcurrent, and other potential issues, ensuring a reliable and safe operation.
