Solar is cheaper than ever? I mean sure, but you still have to pay for it upfront, and by the time you got your money back you need some new panels. Also i like solar power and everything, but i'm not at home during the day, so i would produce energy for no one. Or i'd get a big ass battery, which is super expensive and doesn't last as long as the panels. And no, where i live, you don't get any money anymore for the extra power you produce.
It's also cool that the ocean is being cleaned, but we'll just produce more garbage in shorter time. So far we did plastic straws, which was a big thing that a lot of people are still mad about. And it was just basically a marketing campaign because a turtle had a straw in it's nose. The garbage that is being fished out of the ocean doesn't just disappear. It's better than chilling in the ocean i guess, but it's still garbage twice the size of texas that has to be delt with.
For your first point, sure let’s consider that the case, then the old panels can be recycled and you get more efficient ones, not a bad trade.
Also, share with your neighbour the extra energy? Or contact your municipal office to pass a tax cut/payback? There’s so much opportunity there! (Just imagine if your city passes such an initiative and others adopt too! Less reliance on fossil fuels!)
On your second point, yeah, we need more innovation in recycling technology. Hopefully we get there too 😊
As to solar, payback is usually 7-15 years depending on overhead costs, while most panels are still at 80% output in 20 to 25 years. Batteries don’t last as long as panels when being used to near capacity, but they’ll still do about half the lifespan of the panels. Batteries prices are also falling about as quickly as panel prices, with us now being in the neighborhood of 100 dollars per kwh of storage.
I also think it’s a bit of a misnomer, especially on this instance, to consider these things completely dead and worthless at 80% effectiveness, especially when that is still far more effective than a brand new top of the line one a decade ago. I think that there are a lot of people in the world who wouldn’t mind the system taking up 25% more space if they could get them much cheaper, it’s just that much like EV battery range, a lot of people are finding that they don’t really need to replace the thing away at 80% capacity in the first place.
