extraction from sunlight are of great importance in sustainable energy resources. This report is written
to discuss the effects of temperature and wind on the PV module’s efficiency and how the trend of efficiency
changes with change in the module’s temperature. The manufacturer was the first task for the given material and
power rating values. Powers used for analysis are 105W, 120W, 225W, 425W, and 445W. Comparison of
daily, monthly and yearly values from actual data and satellite values of actual efficiencies, PR and Energy
The generation for Karachi is performed. Results show that the module’s surface temperature is the
dominant factor affecting performance. Wind speed is also related to surface temperature and with
an account of wind, we have lower values of the module’s surface temperature so higher values of efficiencies.
Values of Efficiency and PR change from 1.0% to 3% by accounting wind speed. Analysis of data of the last
five years for Karachi shows that most of the power generation is in March and April. In July and August
efficiency and PR decrease due to increment in ambient temperature

For that we had performed the experiment and collected the data, then both experimental and theoretical analyses are done. Frequency related data is analyzed on MATLAB and simulation is done on SOLIDWORKS software. The frequency response module for a simple beam and beam having mass at the end is checked. The nature of the material was predefined and the first 3 frequencies were measured. All the conclusion related data is shown in the results section, error in experimental and analytical values is due to neglecting masses of different attachments. The error range is from 10 to 25 %. Neglecting mass of accelerometer and unfixed support of beam are causes of error. We can associate graphs and approaches from different means to reach accurate outputs. This report also introduces the feature SIMULATION of SOLIDWORKS to practitioners. The use of SIMULATION is very imperative in design and prototyping. We can easily determine the effect of different parameters on an object when it will be in practical conditions. Due to which we can measure the critical factors and the critical points where the load is affecting. Here, we have studied the frequency response in the SIMULATION module in both conditions (mass and no mass at the end).
