Thank you so much for actually showing the output numbers. So many people talk about the panels as if you get full wattage out of them, it's nice to see some real world numbers.

Bi-facial is good for snow regions, especially ground mounted. The snow reflects the sunlight onto the backside

The Namekian people must love these solar panels! I decided to save a few bucks and get regular panels since my current use case doesn't allow for much light on the back, but I could see a few instances where they would be beneficial. I'm using one of those Elejoy boosting charge controllers and it works great for my ebike batteries. Thanks for the video!

Wow I was thinking about that to 5:00 nice video love the full detailed specs

I've seen these before. IIRC, they mounted them vertically facing East and West. That way, they get, mostly, full Sun in the morning and full Sun in the afternoon.

Such a shame Solar companies Lie ..
I was hoping you woul Test the Old Panel for 100w .. but you didnt ?
Nice channel 👍

I'm very curious about a follow-up episode on this panel. Could you test if another panel would reflect any usable light onto the backside, like in an array? Or test it vertical? Or try a full-blown mirror focused into it? I would really appreciate more info.

It can do a littie more. You are blocking the rear panels propping ut up on boxes or whatever. Legs mounted to the outer frame and a little lift for the entire panel over your driveway or on the roof. Roll on some of that white elastomeric stay kool type stuff to make the roof nice and reflective first of course.
That little panel seems to do the business. Have you tried those flexible military grade ones? You can even partially shade those and rhey still work. I bought a tiny one, like not even $20 and it was pretty impressive. Definitely worth the money just to tinker with. It could definitely charge a phone, probably on a cloudy day even. I want to say it's like 9v so all you need is one of those littie charge/discharge modules. I should probably dust that off and put it to use since i know I bought the charge boards. I got 2 different ones that can charge and discharge at the same time since I am familiar with the quality control of these types of PCBs.

So, bifacial manufacturers are claiming 100 watts is counting reflective power onto the back, that you aren’t likely to actually get except in very specific circumstances ? I think i’ll just stick to regular panels.

i have the 195 watt version of this panel and the Max i get is 150 watts. Disappointing results but it seems these cheap Eco-Worthy panels all produce less than advertised.

Very funny!
Dual Solar systems.
How about if you put a mirror in the back?
Or if you stand on its edge and put two mirrors on either sides?

Interesting panel. How many cells in series is it? The Vmp and Voc might indicate more cells in series. 20 years ago we used to do 36 cells in series with each cell producing about 0.5v Vmp in STC or about 18v. When the panel was actually in the sun on a hot day the voltage would drop down to about 0.4v/cell which is still enough to fully charge a 12v battery. Some cheap panels used 33 or 32 cells and would only produce about 13v which isn't enough to fully charge a 12v battery.

mirrors will cause too much heat in the panels and will then decrease efficiency

And still use wrong .
You have to set Strait up .
You make a fences around your house.
This is not make to set it on a roof.

The panels are made to be mounted vertical to get sun on the back.

Isn't this just two single sided solar panels placed back to back? Seems rather pointless to me unless you were mounting it somewhere like over a lake or snow where sun could reflect onto the back. Otherwise it seems your money would be better spent on two single sided panels.
