ultra light panels don't have a longevity track record and are extremely prone to deterioration when heat is trapped behind them. The cheaper, but heavier framed rooftop panels now can be warrantied for 30 years agains degradation, and unless physically damaged have little reason to take them down after 60 years. LiFePo batteries (cheaper than original lithium) charged once per day, they can last 30 years too.

It's a fair point that chargers and inverters will fail within 10 years or so. If going with LiFePo power station, they might need repair/part replacements, or you can recycle(paid for) the power station that stopped functioning. Power stations can provide value by bunding useful simple connections to a battery in a nice and portable case.

It's a matter of scale to have repair/recycling local industry. Home Depot or other stores not having a large solar/battery section means its less popular, and shipping a bigger portion of costs.
