PROBLEMS
1. From Table 8.1 calculate annual specific output, kWh/kW, for two different wind
turbines.
2. From Table 8.1, calculate capacity factor for Fayette, Vestas 23, Bonus 120.
3. From Table 8.3 , what is the average capacity factor for 1989 through 1996?
4. Calculate the specific output, kWh/m 2 in (a) 1985 for Enertech 44/60 and (b) 1990 for
Enertech 44/40.
5. From Table 8.4 calculate for 7 months for Enertech 44/25: (a) kWh/m 2 and (b) capacity
factor.
6. From Table 8.4 calculate for 1985: (a) kWh/m 2 and (b) capacity factor.
7. From Table 8.4 calculate kWh/m 2 for May and August 1984. Does specific output depend
on the wind?
