// In the 'sunRelative' coordinate system:
// the sun is considered to be an infinite distance directly up.
// this is the rotation of the panel relative to that.
// directly upwards (theta = 0) = coverage 1
// left/right 90 degrees (abs(theta) = (pi / 2)) = coverage 0
// directly downwards (abs(theta) = pi) = coverage -1
// as TowardsSun + = CCW,
// panelRelativeToSun should - = CW

// then for the first 90 degrees of rotation in either direction,
// this plots the lower-right quadrant of a circle.
// now basically assume a line going from the negated X/Y to there,
// and that's the hypothetical solar panel.
//
// since, again, the sun is considered to be an infinite distance upwards,
// this essentially means Cos(panelRelativeToSun) is half of the cross-section,
// and since the full cross-section has a max of 2, effectively-halving it is fine.
//
// as for when it goes negative, it only does that when (abs(theta) > pi)
// and that's expected behavior.
