I put a Unisolar PVL-68 watt panel on my roof in 2012.
Back then it exceeded its output for a month or 3.
Now it does not, but it has not degraded a huge amount either.
But I did not collect hard data then to compare to what I could collect now. In general the maximum output Mid June has gone down by 0.6 amps or so compared to when it was new.
I have it in parallel with a kyocera 130 watt framed panel in use for 13 years now, so the total maximum harvest must include the degradation of the Kyocera too, since 2012.
The low light abilities of amorphorus is a bonus as an equal 68 watt rating of mono/poly crystalline would prehaps push back the time of day that it reaches absorption voltage daily, some unknown degree.
If you got the space for enough amorphous wattage, go for it. It will likely harvest more in winter and in cloudy weather.
