last time I watched about bifacials is it gives around 15-20% more power. I think the panels were 5 feet above the ground, I think to minimize the shadows casted by the panels itself.
Your videos reflect the passion and hard work you put into them.. Keep going, you're making a difference! - "Great achievements are born from great sacrifices.."
Mounted on a boat perhaps, the reflection off the water may improve things, also the higher the panels are off the groound and as much reflective background as possible under and most importantly outside the panels shadow?
I have a Renogy Bi panel, i still haven't mounted in a place where the sun gets the panel from the front and then in the later half of the day shines on the backside. Im guessing that these have to be mounted vertical to get the full benefit? The ideal mounting angel would be let say from 10 Am to 12 Pm the back side of the panel would get the Sun. From 12pm to maybe 5pm the front side of the panel would get the rays. Ive seen some pics where all the Bi Panels were mounted straight up and down.
On the Solar Tracker, leave one normal panel and place one Bifacial panel of the same size for direct comparison, or create a second Solar Bifacial Tracker with panels of the same sizes for direct comparison. You can then experiment with different surfaces under the Bifacial tracker, whatever you like, but white surfaces or reflective foils will be probably the best. It would be interesting to develop some sort of shaped surfaces on the sides or around, and mount it permanently under the Solar Bifacial Tracker so that this reflective platform moves with the Bifacial panels and reflects sunlight on the back of the Bifacial panels as optimally as possible during the whole day. I'm very interested to see what you came up by your experiments with the Bifacial panels.
Bifacial panels work best when they are at least six feet up off the ground from what I’ve see. Like on a pole array or tracker. This way they are not in their own shadow.
Could you try wrapping the box in aluminum foil and positioning it so that reflection from it hits the back of the panel? I think this would provide a best case for reflected light to determine the maximum gain from bifacial vs normal panels......thanks.
Great video, I have a much clearer understanding the benefits of bifacial panels. I wonder what your output would be if the panel was flipped face down?
To get light on the back is definitely when the sun isn't square to the panel. Also if the panels are elevated so the sun also hits the ground under the front of the panel you get more from the ground. Imagine a ground mount with the front lower edge of the panel several feet above the ground. Then if you have light colored rocks on the ground...
That's a good point about the front of the panel being elevated. In that scenario we would get gain when the sun is squared up with the panel. All these comments are great, and now I need to test more stuff. Thanks!
I have 2 of these panels, tried today for the first time, front only, connected parallel to a bluetti ac180, most watts I got was 155... But angle wasn't ideal...but dam .I figured I would get at least 100 per panel...should I try connecting in series ???
Yeah, you need them in series, not parallel. Check your open circuit voltage with them in series to make sure you're under the 60v limit before connecting them to your Ac180. If they are two12v panels in series it should be under 60v but it's wise to check. Thanks.
I noticed a difference when I had my camper panels vertical (lifting mechanism failed) that they generated power even when the sun was hitting them on the back of the panels in the morning though not as much as in the evening. These were not "bifacial" so I suspect this bifacial is a bit of a marketing stunt as all solid panels exhibit this behaviour to some degree.
Oh that's awesome, so you were producing from the back of standard panels. That makes sense, the baking on them is just a thin white sheet for the most part. How much do you think they were producing, 5-10%?
@@BradCagle They were only producing morning (back) and afternoon (front) and they were giving me around 5A morning and 15A afternoons, so probably closer to 30%.
I think that while the IDEA to lift up the panel BASICALLY is good, you changed the angle towards the sun, and LOST some watts. If I understand correctly, you need the reflecting material OUTSIDE of the shadow, to reflect light IN. Putting reflecting material IN the shadow, gives minimal gains.
There seems to be some concern that over paneling your charge controller may cause damage to it. The reviews I've seem to indicate that what most often happens is that the current is limited to the maximum output of the controller. To these things, I add that you probably will rarely, if ever, receive the maximum rated output from your solar panels. That rating was based on ideal conditions operating at room temperature. which, in my view, is reasonable to substitute 75% of the panels rated wattage when calculating what size charge controller you will need. Then leave a little more for headroom.😂

150W max from a new bifacial 200W panel seems low. That's 75% only and the conditions look to be really good.

I've got 2 bifacials from JJN Solar. They look a lot like your BougeRv panel. They perform very well, i've seen 180 watts at times.
That's awesome. How do you have them mounted?
@@BradCagle Just free-standing really. Series with a couple of short mc4 extension cables.

Try putting a mirror for the reflection of the sun to the back side, hmmmm
Yes there is a good idea there someplace?
IIRC, bifacials are meant to be mounted up off the ground. That way they collect the reflected light from its surroundings.
...collect the most reflected...
Did you turn the panel over to check the best case / relative power from the rear?
No, someone else suggested that too, and now I need to try :)
On the Solar Tracker, leave one normal panel and place one Bifacial panel of the same size for direct comparison, or create a second Solar Bifacial Tracker with panels of the same sizes for direct comparison.

Great Ideas. Would be neat to have a mppt per panel, and log the data independently. Thanks

That make sense, Thanks!
I agree, an aluminium sheet could reflect the sun light this will help

I have roll of radiant barrier that's super shiny, I should try that. Thanks
Great video, I have a much clearer understanding the benefits of bifacial panels. I wonder what your output would be if the panel was flipped face down?
That sounds like a great suggestion to flip the panel face down.
I remember seeing someone do that not too long ago on another video and it was outputting about 40%.
@@YouLookinAtMe-Bro Thanks, good info.

Looking forward to your review of that AC70 unit!! 😉
I have no idea what you're talking about 😉But whatever it is will probably be after the 20th 🤣

@@BradCagle Thank you!! Will do!! .
@@BradCagleyes. In series its getting about 290-310 watts...much better. Sometimes it drops to half that for a few seconds then back up.
@@michaelsparti Right on!
What happens if u stand a bifacail straight up and down like a fence
Just for info I have 2 older Kyocera 140w panels in parallel and I have never seen more than 200 watts from them
try another video with foil or mirror underneath
Alright, I will. Thanks
Pretty cool. Thanks!
You're welcome
Put the panels over the pool. Heaps of light bouncing around there !!
All panels should have space left under them. It allows airflow under them which increases efficiency.
Love this video! Subscribed, and I'm eager for more insights! - "Success is the result of your continuous journey.."

Add a mirror behind it

Yes, yes, mirror. Yes.
Should of put the panel upside down on the box and see what happens.
Great idea! Thanks
Don't think the bifacials have the tariffs on them which SHOULD make them cheaper...IF the savings is passed to the consumer.
Oh really, nice! I do see this panel is cheaper than the monofacial counterpart on their site. Thanks for the info!
By facial panels am meant to be vertical, basically stand straight up and facing west east or east or west

lol need 2 suns
Haha! Yes indeed.
hmmmm

Must be low quality fake panels?? Seems like eco worthy panels same result. Shame
