I bought my current house with a specific clause that the solar panels were 11 years old at the time, the transformers were at the end of their lifespan and the panels strongly degraded.
now, 12 years later, the panels are performing at abooout 95% of new, when adjusting for what the sticker claims and how the new panels perform on the same roof. 1 of the 6 transformers has also died. Granted, that was shitty to replace, it was one of those “plug one panel into an outlet” things that were common back then.
It’s definitely not altitude that’s saving them, I live about as low as anyone on earth, below sealevel

So, it takes burning 1kg of wood to generate 25 Wh, or 90kJ. One kilo of wood contains, roughly, 20.000kJ of energy. That’s about 0.5%.
It’s fine if you want heat at that time, but quite a bit power demand is when you don’t need any heat.
It also creates huge problems with particulate pollution that are tied with all fossil fuel heating systems.
