Should I use a centralized inverter or microinverters ?


In terms of costs, centralized inverters are generally recommended for installations over 3kWp and microinverters for installations under 3kWp. Microinverters can be relevant for certain installations above 3kWp as well: for instance installations with the presence of shading or installations with different facing roof areas (for example when there is a solar field facing east and one facing West).
