7.7 A mini-grid is to be implemented for the community of Ababju. The com- munity has 500 households. Each household is expected to consume 600 Wh per day. Assume the power consumption is constant throughout the day. Let the daily irradiance of Ababju be 27 (t – 6) G(t) 700 sin 24 where t is in hours (valid between sunrise t = 6 and sunset t = many of the modules described in Table 7.3 are needed to power Ababju. Assume that the mini-grid contains sufficient and lossless energy storage so that the excess energy produced during the day can be used to power the load in the evening. 18). Determine how
