@doonxib @db @WandererUber @sickburnbro There is a very smart channel I watch on youtube, called Tech Ingredients. it's hosted by an engineer and his assistant who go into detail explaining how things work (or don't work).

He covered how inefficient solar panels come out of the box due to their contradictive nature. The solar cells need peak UV radiation to get the most power out, but the heat absorbed in doing so lowers the conversion as well as the lifespan of the panel. The solution would be to add heatsinks and fans behind the panels, but this adds a lot of weight to them as well as the cost and effort needed to make it as there are very few companies that are even looking into it.

My dad lives offgrid and bought solar, but tells me all the time about the problems he has with them.

Also note that the advertized lifespan of these panels are projected and not actual. Many of these panels have not been around as long as they claimed they live and are already failing. They cannot even be recycled and end up in landfills, while containing heavy metals that will leech into the soil.
