The average lifespan of a solar panel is 25-30 years
No. It's about 10 years in real world applications. Just like LED lighting which should have a very long operating life but doesn't live longer than a few years, photovoltaic solar panels fail long before their theoretical lifespan due to environmental factors mainly. That greatly reduces their lifetime efficiency which is used to determine how wonderful they are at getting (((climatologists))) pussies wet. It's all a (((scam))).

It depends on how much you pay. Cheap LEDs die because of cheap low quality drivers from China.
