What extra accessories available commercially ?
I have one and it clocks over 100w and that is really good compared to many other Chinese flexible panels I got which they can't even break 50% of advertised spec. Avoid Werchetai panels on eBay... they get 45w out of 100w.

- 25 to 30 years is standard.
- Most panels still produce 80–90% of their original capacity after 25 years.
📉 Degradation rate:- On average, solar panels lose about 0.5% to 0.8% efficiency per year.
- After 25 years, a panel rated at 100W might still produce about 85W–88W.

Flexible panels made with Si are just asking for trouble--the panels will flex with wind/weather/handling and crack with even the slightest load. The plastic/fiberglass module itself may look and feel intact but the underlying Si used is extremely fragile and prone to cracking, which may not be obvious to the naked eye.
To the people asking about expected lifetimes...I would not expect more than a few months. Once the cracks start to occur you will see dropping Isc (current will drop permanently, and as a result, lower power or wattage) as the micro cracks propagate. This is going to happen much sooner than the natural degradation.
To the people asking about applications...at a minimum you will need an adapter for the included MC4 connectors. But I would not risk charging anything other than a battery bank. This amount of current and power output can still be extremely dangerous. You will need more panels to charge anything substantial (like an EV battery for example).
Save yourself some time, money, and effort by at least buying a solar module mounted on a glass substrate and supported by a metal frame. Yes, it's heavier but it's much much more likely to do its job.

Most EVs are AC only- so need an inverter? Is there a portable converter?
