The general rule of thumb for sky/far cycs is that you want to place your units on centers whose distance for center to center is equal to the distance from the cyc. This means that if your cyc batten is 8' from your cyc then you should place your units on a maximum of 8' centers. If the batten is 5' from the cyc, then 5' centers. So, by this rule, you need to know how wide your cyc is and the distance your electric is from the cyc. then divide the width by the distance and that should give you the minimum number of units required.
