Hi Jeff,
Thanks!
i found the calculator and itīs probably giving a very good angle. Iīm close to Nueva Palmira and it returns 41 degrees for optimal winter sun.
I find it curious that they calculate the angle relative to a vertical surface, is that the norm? So 41 degrees vertical would be 49 degrees relative to horizontal.
There is a lot of factors and preferences to take into account. I made my own calculations based on kWh data from WeatherSpark and sun angle from suncalc.org. And itīs hard to say where the optimal point is. I guess thatīs very individual depending on preferences. It getīs even more complex if we have to take preference whether we want more energy early/late or at mid day into consideration
49 degrees relative to horizontal is definitely not a bad angle for winter sun.
Iīll definitely get myself an adjustable mount, so I have the option of changing my mind
I would have liked to post some graphs from the calculations I made, but I canīt post pictures yet.
