Hi, I live in the south of Spain so plenty of sunshine to take advantage of. I have been gifted a couple of 450W panels and would like to have a go at building my own system as far as possible. Don't really know a great deal about solar systems and so would appreciate some advice about what sort of system architecture to initially aim for - i.e. Buck converter + Inverter, PWM Controller + Inverter, MPPT Controller + Inverter etc. Would also appreciate if anyone has circuit diagrams for any of these items - I'm planning to run the 2 panels in series so around 80-90V and 10 or so Amps. Planning on a 3kW sine wave inverter as I will probably expand the capacity once this is up and running. Thanks.
