been thinking about this one for a while. everyone obsesses over which panel brand to buy but over 25-30 years how much does the module actually move total output compared to inverter efficiency, install quality, shading, site conditions? my gut says install and site dominate the first few years and the panel's degradation curve only really separates brands over decades. is that right or am i underrating how much the module matters? curious how people who've actually run the numbers see it
