You are aware of the variation of wind and solar energy generations throughout the day, therefore considering a battery system to store the excess electricity generated when electricity demand is less than generation. After calculation, you notice that not all excess electricity can be stored by the battery system. [Prompt #2] calculate the capacity ( in kWh) of the battery needed to store all the excess electricity generated in a 24hr cycle [5 pt] [Prompt #3] the above question does not consider charging speed of the battery. Calculate the hourly storage capacity (in kWh/hr) of a battery system (12V, 2.44) using the following equation [5rd _VxI s xt \"T 1000 Where: Sm: hourly electricity storage by charging the battery, kWh per hour V: voltage of the battery system, volt I : electric current, ampere t: duration of battery charging, hr [Prompt #4] calculate the amount of electricity sold to grid each hour aer storage Mint: 40% the energy is lost during battery charging, therefore cannot be sold to grid) [5 pt] Based on the preliminary analysis above, you would like to get an estimation of both the monetary and carbon payback periods for your investment. [Prompt #5] use the information provided in Table 2 to calculate the monetary and carbon payback periods. Hint: the information you will use is based on \"average daily electricity consumption and generation \" [15 pt]
