Wind
Turbine Shadow Calculator
Do not operate the form until
this page and its programme have loaded completely. Otherwise
the program will complain about missing data, and you will have
to click Reload. This
calculator lets you experiment with your local conditions to
determine the shape and size of the local area which may be affected
by shade (light flicker) from a wind turbine. For an actual project
you will probably want professional wind project software which
will help you with a lot of other aspects as well. (See the Links section).
After changing data, use the tab key, click
the Calculate button, or click anywhere on the page outside the
field you have updated to get the results in the right column.
To get a plot image, click on the Plot button. Click on the question
marks for help. (If a plot windows disappears, it is probably
hidden behind this window).
