Question

Note: This assignment consists of three parts. Part I on Grid-connected PV systems (Marks 4), Part II on the sizing of the battery bank and the number of modules calculations for an off-grid system (Marks 4), and Part III is on the performance of solar water heater (Marks 2). 75% of the marks are allotted for calculations and 25% for the results' discussion. | Part I-Grid-Connected System Design Calculation: Table 1 shows the design and performance calculation steps of three grid-connected photovoltaic systems (A, B, and C). Calculate the values of empty boxes for each system (please follows the same procedure as you did in the assignment 3). Table 1: Parameters System A System B System C Each PV Module DC Power Capacity (at 25 *C) 150 W 200 W 250 W Number of PV Modules in the above System 30 30 30 Area of each Module (m-) 1.8 1.6 1.5 System DC power rated output (W) Module operating temperature (45 "C): De-rate 8% 8% 8% (reduction) of temperature System output power after temperature de-rate (W) (Losses:8%) System output losses due to wiring: De-rate (reduction) 2% 2% 2% of wire losses System output after including wiring losses (W) Inverter DC to AC power conversion efficiency 95% 95% 95% Inverter Maximum AC power output (W) Average daily solar energy at the site (Peak Sun Hours) 4 PSH 4 PSH 4 PSH Average daily energy production of the site (kWh/day) Feed-in-Tariff Incentive rate (2014) (Govt. was paying to $0.40/k Wh $0.40/k Wh $0.40/k Wh generate solar electricity) Daily earnings from this project ($) Annual earnings (Assuming constant output each day) $ Earnings in 20 years (Assuming constant output) ($) Project Cost (include module, inverter, installation, $20,000 $18,000 $16,000 accessories & permits) Simple pay back from this project (years) Total net earnings in 20 years ($) Monthly earning from this project ($) Total roof area for this project (m Annual COz avoided by this project, if the system is replacing a coal-based electricity (0.890 kg/kWh) (kg) Please calculate the following values of Table 2 with the help of Table 1
