1.Participate in class discussion on the meaning of load profile.
2.Research the meaning of energy demand, system voltage, and days of autonomy in groups.
3.Determine the energy demand of a given facility in groups by the following steps: • Identify and note the power rating of the loads that the solar system will supply in watts, then determine the number of hours each device will be used per day and consider the duty cycle (e.g., a refrigerator runs intermittently). • Calculate daily energy consumption for each load using the formula: Daily Energy Consumption (Wh) = Power Rating (W) x Usage Hours (h). • Sum Daily Energy Consumption by adding up the daily energy consumption of all loads. • Calculators • Charts • Power rating tags • Solar panels Students to:
1.explain what load profile is;
