the panels are the least of your problems.  the main problem are and always will be the electrical components, aka the inverter, its also usually the most expensive part, except if you go for a ultra cheap chink one that will grill itself after 5 years.  also, if you don't have any storage solution you will not get any money on peak solar hours, as they will simply cut your panels off, maybe you even have to pay for your system to input power into the grid, because when peak shit happens there is to much electricity produced. germany already shits their pants for a blackout to easter.   aft/2024-11-17/fe2947ea3e6d16671f31 c6b83ed65273/?gepc=s3 > to much unregulated private solar installations > clashes with low demand on holidays > with a power grid that can't cope with it
