Is there a minimum size for the photovoltaic system I should install?
No. How small or large the photovoltaic system you install can be depends mainly on two factors: a) the available area on your building or property for installing the photovoltaic panels, and b) how much money you are willing to invest.
For example, you could install a system that covers just 20% of your needs (if you have limited space and money), or, of course, cover 100% of your electricity needs.
