You are designing an off-grid solar power system with battery back-up storage for your log cabin in northern michigan. you use batteries to store excess electricity produced by the panels, which are discharged to supply the energy demanded by the house. use the following system parameters in your analysis:
pv module efficiency (at 1 kw/m^2 solar intensity): 20%, capacity factor: 14%
installation price: $6/watt (rated power), area per module: 1.5 m^2
1. the average power requirement of your cabin during the daytime hours is 1 kw. how many modules must you purchase, if you would like to produce enough total electrical energy to satisfy this demand for 8 hours/day (round to the nearest module)?
