    I wish we could still install the old panels somewhere. They might not be good enough to be rooftop solar anymore, but in the field, why not take all they can still give?

      Because solar panels are dirt cheap to produce and your time and construction materials and land has value. Recognizing trash is vital for an eco friendly economy.

      Edit: some red necks do use old solar panels for off grid, low cost setups.

          Yes. But they don’t produce power by themselves. They need light. Hence mounting, countryside etc. That’s effort.

        But that relies on the capitalist assumption that producing trash and CO2 is free because you can dump it withouth having to pay for it, and destroying nature to stripmine for the raw resources only costs the purchasing price because the environment isn’t monetized.

        Plus the imperialist assertion that providing decentralized electricity to poor people in developing nations is net negative because it increases the cost of labor from those regions because they can do other productive things than work in your factory.

          No. It relies on the assumption that newer panels produce more energy hence are more eco friendly.

          Plus: I explicitly mentioned them being a great opportunity for the poor.

          Also Pakistan is rapidly building out solar panels without that.

            Depends on how you define eco friendly.

            The old panels already exist so if you can use them without having to transport them across the world (like the parent comment suggests), continuing to use them is eco-friendlier than producing new ones, which requires additional CO2 from manufacturing

              Not doing anything at all has the lowest emissions. But it is obviously not the best way to curb impact while preserving lives and quality of life.

              Your adversity to investments that do pay off would be a great hinderance to society as a whole.

              Solar panels can be recycled, take very little materials and manufacturing and are usually not the limiting factor when it comes to transitioning into a low damage economy.

              Throwing away great amounts of cheap solar power because you would have to lift a finger to achieve it is not… Great.

                Using something that still works as long as it doesn’t produce emissions…. Is actually the single best way to curb impact, yeah.

                Like literally the best use is long-term. If it still works and you can eek some power out of it rather than toss it, there’s no harm doing so.

                Assuming you can recycle it now, you can also recycle it down the line when it genuinely isn’t worth keeping anymore. Until then, if you’ve got space, might as well. Because recycling isn’t free, in energy, emissions, or labor.

                preserving lives and quality of life.

                ROFL what? Continuing to use old panels in addition to new ones harms lives and quality of life? Ridiculous.

                  Limiting your power output may cause more fossils to be burned. You ain’t got permits or ability to put up solar everywhere. You act like infrastructure and land is free and then ridicule me.

                    Limiting power output cause more fossils to be burned…? What are you even on about? Nobody said use old panels instead of new ones for absolutely everything, yet your argument is based on that, best I can tell, pretty much entirely.

                    You act like nobody can possibly have their own land and a use case for long-term low-power-draw use. That’s why it’s ridiculous.

                  They too can. Their materials value is rather low and the available amount of panels is way too small to make it worthwhile today. That will change in due time.

      You’ve got to have space you want to use for them. Just because I have 10 200w panels for free doesn’t mean it makes sense to mount them on my roof (which is the only space I have facing the sun), because 400+w are available now and it costs money to mount them.

      But it might not make sense to take down my 20 year old 200w panels and replace them, or maybe I can sell them to someone with more space.

        Sure! That’s why I talk it might be critical for rooftop, but maybe useful somewhere else.

        I’m pretty certain it may make economic sense to install something like this in a large open area. If the panels were meant to be thrown away, the price must be tiny.

        Anyhow, I expect this to be more common once the mass-produced solar of the last decade gets old. We may just not be there yet to have plenty of used solar to offer.

        My goal one day is to have enough yard space to do an on ground set up. Insanely cheap if you pick up some used panels. The average person would only need an electrician to hook it up to the house.

        I understand not being comfortable with diy roof mounting, I know I’m not. The costs scale quickly when it goes on the roof

          Ground mount has to address wind load which can be significant. I think the standard is around 500kg wind lift per standard panel. I’ve got a number of 200w panels I haven’t set up because I don’t have an inverter but also because they’re a pain to anchor.

            I’ve never lived in areas with high winds. I’ve seen some people with very simple plywood frames to hold their panels. They’ve held for years without issue. Totally regional though

              People get away with a lot, but as you note it’s regional. All it takes is one gust of wind.

              But I do have a steady average 8kt wind (I mean average over last 5 years day and night), but gusts and storms push 50kt. I wish wind power was more accessible like solar has become; I live in an area that’s frequently the windiest in the country. I’d be able to use it as primary generation and solar for top off.
