but I don't keep that close an eye on the outputs. I used to keep monthly charts, and took random readings during different days to build a graph of typical output during different months. I haven't compared those old graphs to newer data for a year or two now, but that's a darn good idea. I'll let you know.
I still occasionally see the system up to 90% of it's rating, which is pretty good.
They should last decades, two, maybe three if we are lucky. I haven't checked the panels direct output for several months, I should get out the meter, climb into the attic and check those leads.
We've not researched newer panels mainly because we don't want the cost of up-grading while these are still doing their job really well.
I don't know what we'll do if this thing goes through.
