Welcome to the forums!

I put Jose Pedro varela into the solar irradiance calculator and it said:

42 degrees optimum winter angle
57 degrees best overall angle
72 degrees optimum summer angle

With the overall angle, it looks like you get about 6kwh per day per square meter in December and January, dropping to about half that in June and July. Fiddling with panels can boost June and July to around 3.6 or so, depending on mother nature. Here's the link:

Main thing I can tell you about solar is if you're serious about it, do it right the first time and enjoy your power source. Plan the whole thing out before you go shopping for materials. Consult with suppliers and a local engineer and spec out the drawing. Figure out details with the power utility and local government. This homework will pay you back in longevity and reliability for a long time. Not doing the homework ahead of time and just eyeballing and rigging things will definitely come back to haunt you.
