What is this tool used for?
Estimate spacing on level ground from panel length, tilt and the sun's elevation at your chosen design time. This two-dimensional shadow check does not cover every sun direction or roof obstacle.
How this is calculated
h = L × sin(β); g = h ÷ tan(α); p = L × cos(β) + g; L = Panel length · metres; β = Panel tilt · °; α = Solar elevation · °; g = Clear row gap; p = Row pitch; h = Raised height
