A remote orphanage is looking at energy solution for all the electricity load related their regular operation. They have approached you regarding the design of the system The client requirement is a full load energy system design (Stand Alone Sveter using some renewable energy sources only. Use the attached tables and conditi given to design and calculate the system discussed. a) Calculate the average daily energy load and peak load. Also tabulate the subtotals of each category of electricity consumption units. b) Calculate the battery bank capacity needed in voltage and ampere hours for full load and lighting loads. Select the appropriate battery configuration.- c) Calculate the separate inverter size for full load and lighting load system. d) Design and sketch PV system with suggested configuration each for summer and winter design using respective average PSH and temperature, mentioning the number and arrangement of PV modules to compliment the battery bank. (Hint: Temperature above 15 °C is summer months) e) Show the average wind speed at installation height normalized for given surface roughness. f) Design a wind farm each for best and worst wind months, mentioning the number of wind turbine of given specification needed to sustain the energy demand if the installation height is mentioned to be 30 m above ground level. (Hint: Wind Speed above 4 m/s at 10 m is best wind months) g) Prepare a list of essential maintenance and monitoring equipment with function for both PV and wind systems.
