People die every year. A lot of people. So go to the CDC website, and start looking at the TOTAL number of people that died every year since 2010 in the US (Not third world, modern contries). You will find the data harder to find past 2020, but just get the totals and graph it, just the total for any reason. Then tell me what you see.

I know 20 years ago, 8,000 people died every day from all causes in the US

140,000 died everyday from all causes in the world

one needs a valid point of reference to know reality

Very nice panels indeed: N-type, high bifaciality factor and excellent temperature coefficient. :cool:

But I still get nightmares about installation.

Only logical choice extend the pole string and see if you can make em snap with the huge sails from three of them glued in an assembly.
 
What's with the (up to, obviously) 85% bifacial (80% +/- 5%) claim anyway?? Just marketing?? Or did something change. As long as we blast backside with STC conditions = additional 85% output per datasheet...
 
If you install these panels with their backside facing the sun they should make 85% of their rating, assuming no light hits the front side. With normal ground albedo under the panels bifacial gain is up to 20% making total output 846W.

One of the panel breakage problems solved.
Let's see a forklift operator stack on top of THAT pallet.
Couldn't quite reach the roofrack on my pickup, we ended up lifting bundle of rails and sliding on from the end.

Unloading, now ... more likely to tip and take me with it. Need to make a 2x4 frame to brace it while pulling panels one at a time.
 
Shadowmaker has 700w bifacial panels NOW. His existing are probably larger??

I have newish 2yo 380W (non bifacial) panels. These are 55% more area but 85% more frontside power alone ? ? ?

Mine are only 70+/-5% bifacial, but they are 22,8% efficient so they are actually smaller than these CS panels (22,7%). Reading from the specs mine are 1,3kg heavier though.

In any case no one should ever get panels this size unless they know what they are doing. Of course it's also possible to be an ignorant idiot like I was/am.
 
I would not use anything bigger than the 530W panels I have.

  • Dimensions: 89.25" x 44.2" x 1.27"
  • Weight: 62.8 lbs.
It was enough, you are not doing these alone. Wife and daughter helped and I installed all but one standing on the ground with array flat with the MT Solar mount.
