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 perday. Assume the power consumption is constant throughout the day. Let the dailyirradiance of Ababju be27 (t – 6)G(t)700 sin24where 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. Assumethat the mini-grid contains sufficient and lossless energy storage so that the excessenergy produced during the day can be used to power the load in the evening.18).
