The roof of the house we bought is totally shot, it all must be totally rebuilt (rafters and all).
So I'm thinking to just make a flat roof tilted at a certain angle or angles to optimize our solar production.
We'll make it generally South facing and the builder said he can do about a 20 deg. angle (he balked at 15 deg.)
So I was thinking about it and wondering if a secondary angle would be beneficial since it's all being rebuilt from scratch anyway.
If so, does anyone know of any tools to calculate the best stationary angles for 2 axis?
We live fairly close to the equator and there are some trees to our West we cannot cut down (effects later afternoon shading) so I'm also wondering if there could be some sense to tilt the roof a bit toward the East...
The house orientation now has the Southern exposure at South but slightly facing East (9 deg)

The rainy season is here June-November, would it make sense to just focus on the best average angles for that season? I'm wondering if the diffusion of light in the rain will make optimal angles less important?

It says part of the year the best orientation is South but part of the year it's North and Northwest.
