Solar panels

Hi
Hunting for advice.
The house I have moved in has a 1.5Kw solar inverter and 6 panels that generate a maximum of 900 Watts.
Seen in Leroy Merlin new 420w panels and a 4Kw inverter.
As I have the infrastructure i.e. roof tracks and current integration to my electric network would it be as simple as buying the equipment and swapping it over.
Cheers

You would have to upgrade the Inverter to take the bigger load from the new panels and the system you have may not be compatible but you can add a second independent system. You would need a professional to cost it for you. There is good advice in this link and it might answer questions you have. They are referring to Irish regs and standards but any Spanish installer will be up to spec on the Spanish system.
