Bifacial solar panels can generate electricity from both front and rear surfaces, and their power output is significantly affected by shading, as demonstrated by a 440W panel producing only 144W when partially shaded by a palm tree at 2:00 PM in mid-May.

I bought the 440W solar panel from Bunnings! | Powerbay N-Type BifacialHinzugefügt:
So, today I'm picking up two of these power bay 440 W panels from Bunnings.
121 each.
They're going to be powering my dad's EcoFlow Delta 2 Max, so one each. And actually it came to uh 217 80 for both cuz I have power plus.
And my dad's somewhere down there getting a trolley and I'm hiring a hiring a well, getting a free trailer I have to borrow to put these in. I'll take you along for the ride.
Okay, this is how we're going to get it out of the store.
All right.
Okay, we are going to chuck it in one of these 6x4 trailers.
I don't have one of my own, but Bunnings give you a free courtesy trailer.
Dad's laying some frame down there.
And just for reference, a 6x4 trailer exactly fits this solar panel. All right?
Okay, we made it home.
So, we're going to mount it up here.
Gosh, let's swing it back a bit further so you can see.
On the flat part of the roof.
Currently, the panels are over here.
Long run.
And yeah, he's got a lot of old grid panels, but the voltage is a way too high.
And you know, they're a bit degraded for the Delta 2. So, that's why we just went with the one one 440 W for each Delta 2. He's got two of them.
And then we will just um he's got another 12-V system inside the garage and we can use the grid panels up here at some point. Add more capacity and more charge controllers, so we will be able to use these old grid panels.
Okay, we're going to be using these Eco-Worthy Z brackets, I think they are.
And yeah, just for easy to install.
And I have a bit of this tape here.
Uh obviously don't want metal against metal.
There we go.
Okay, we're up on the roof. [snorts] There we are.
I'm going to disconnect these panels and use this one instead.
And I'm going to move that one next to it.
Okay.
Nice view from up here.
And these are the existing grid-tie panels.
Okay, so I'm just tying off some MC4 connections and I need to cut this cable here to reuse it.
And um it's twin core, so I'm just put that to prevent any more power going through.
How funny.
Okay, we are done. As you can see that palm tree is really annoying because it shades the panel at this time. It's about 2:00 p.m.
And we are in mid-May.
So, that won't be a too much of a problem in summer, I don't think.
It's a bit shaded there.
But um here we go.
Let's have a look. I checked both EcoFlow apps and they are working as much as I can at the moment.
Not the best of jobs, but it's tied enough. This is tied off underneath.
And I'm probably going to run a cable to the shed there.
And get these other panels off the ground.
See if you can see them clearly.
They're down there.
So, that's enough for today.
These bifacial 440 watt things N-type panels from Bunnings.
They are fine. They're just really big.
They are physically big. Bit of a bit of a problem if you're on your own, but help with my dad.
They work for now.
So, it's about 3:00 p.m. in the afternoon and it is autumn.
I'm checking out the panel. Yeah, still a bit shaded, but getting 144 watts. So, not too bad.
So, there we go.
Um I will share some uh details in the app once this shadow comes through late afternoon. I don't know how much it's going to get in that time, but I'll keep you updated. Catch you next video. Bye for now.
