|
| From
the above graphs it can be interpreted that as more turbine are insalled
there is a linear increase in CO2 savings per annum |
|
|
|
| It
can also been seen that the amount of power derived from the turbines facing
due west is greater than for the turbines facing due south |
|
|
| It
is estimated that the maximum amount of turbines that could be installed on
the building at the Rottenrowsite is 14 facing due west and 14 facing due
south |
|
|
|
|
| Combining
the amount of electricity generated from 600 BP585 modules, 14 ducted
turbines facing due south and 14 ducted turbines facing due west |
