It is expected that the solar modules will deteriorate by no more than 0.5% per year. This is covered under the performance warranty of the modules. In this manner, the modules will be producing more than 90% of the Year 1 electricity after 10 years and more than 85% after 25 years. In this manner, the system is expected to produce a total of 28.405000MWh over its useful life, with an average cost per unit of Rs. 3.47per unit (after including O&M costs). In this section we provide the financial feasibility and payback analysis. Using the production estimates outlined in the previous section, we calculate the payback period of this project to be about 4.32 years for FAZAL-E-RABBI TEXTILE MILLS.
The detailed calculation of calculating energy production takes account of various factors including climate data, angle, orientation, solar panels and inverter efficiency and also accounts for losses due to conversion, cabling, soiling etc. These detailed calculations are provided in the technical section. Below, we provide the results of the simulation to show the expected variation in energy production on a monthly basis.
The system is expected to produce 1345213KWh/Per Year of electricity annually, with peak production during the spring and autumn season. This is usually when the industry is in session with peak demand. Production is slightly lower in July and August due to monsoon season and high temperature.
