@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.
My dad's system is not a DYI, but with the US, the largest problem is sub contracting and frankenstein parts. It works, but he has to make minor adjustments all the time and the guy that installed them isn't big on customer service. Most of Solar Panel companies in America operate solely as sellers of contracts and they sub contract the parts and labor through a 3rd party. More often than not you have no idea what kind of work or product you'll be getting until you get it, and I've seen enough BBB reviews and cases on the companies that reached out to me and those I've researched to stay clear of.
Those articles only show proposals and plans, which means nothing until they go into practice. Look back to all the green proposals made and see how many of them flopped once they started building.
Maybe they will get their shit together and pull it off, but for the moment they are are bleeding money, hydrolic fluid and breaking down much faster than their 'projected' lifespan.
