Get your startup plan in order. In 20 years you can become the "Uber" of solar panel disposal. Because you can't even throw away a fluorescent bulb with most garbage collection services. Imagine the amount of toxic chemicals we will need to get rid of when these solar panels start to wear out en masse.
Why would you throw out a paid for PV system? It's a sunk cost unless you're running out of roof space and need more power. The efficiency only drops some 20% over 20 years.
