Do any of you actually own solar panels? The prior owner of my home installed solar in 2013, I moved in here in 2016. I have 68 panels on my roof. From 2013-2016, they produced over 22,000 kWh of power. Now, only 8 years later, I am getting around 17,000 kWh of power per year. I had an issue late last year, and when the company came out, they told me that my panels and inverter boxes are already outdated. It took months for them to get the parts they needed to fix it. With such a huge decrease in efficiency and how outdated things are in just 8 years, I feel that solar on a massive scale would require constant upgrades to keep up with newer tech and also frequent changing out to new panels in order to keep up with the current demand. That isn't even considering higher demand, which would need more and more panels installed. They can tell you that panels last 25 years, but it seems like efficiency, at least for their highest output, only lasts maybe 5 years then there is a steady decrease year to year.
