I don’t think there can ever be something like too many panels, especially if you already own them and already have the MPPT capacity for them.
True.
But I suspect next winter will also see me even more content and chuffed.
There will be no shade this time as the roof house is very very high. That and the fact that they are now properly angled for winter sun trajectory. They were basically flat on the garage roof.
The way things are going now, my existing panels will lay idle for most of the day. I need to find work for them as my ROI just got extended by a couple of years.
Here is a before photo taken from the house’s main roof.
Panels are going to be another 4 metres higher than this.
And this is what it currently looks like.
Lots of cleaning to do before my garage also gets another roof to finally stop all leaking issues.
Just the final cabling to still be done.
Here they are up top.
Will try to upload a short video clip also that will demonstrate:
- The height of the roof
- The number of trees to the east and west of the garage that they had to contend with
- The fact that at 15h40 when I took the video clip the garage was already covered in shade
- And that there is still no shade up top.
Seems I cannot upload a video here. Pity.
Last feedback, then I’ll stop yapping about this.
Remarkable difference! My baseline over these past few days was that before relocation, the panels produced 150W at 06h20
With all of them on top, this figure is now 600W at the same time. Very happy about this.
As I type this they’re up to 1128W at 06h50. Even with both my neighbors chopping down their trees this would not have been possible.
Sorted for years to come me thinks.
Keen to see your peak output. Switch off the MPPT’s till 12:00, let the battery develop some headroom, then let them roam free…
Good idea. I was thinking about this too having been on only batteries the entire day yesterday when they completed the installation and thinking I might reach midday without a full SOC.
I started of with 38% this morning but at the rate things are going now they might be full long before then. Currently at 56% at 08h08
Is there anyway to post a video here? Or do I need to upload it somewhere and provide a link to it? I don’t know how to do these things.
I would link it from Youtube. (http://studio.youtube.com)
You can set the video to Unlisted and just add the link here…
Works well… When they are clean they will be even better
True, but that would’ve skewed the results. Dirty at the bottom so they must arrive dirty at the top.
The guys are finishing last cable trunking now then I’l hand them a pressure washer before they close the roof again.
Those frames used, are the sufficient for storms/wind?
Question because I’m a Capetonian and therefore very sensi to panels and frames and stuff.
EDIT: More specifically, that thin little upright pole at the back …
Here is what I get currently.
I have seen peaks of 6000W but that is on colder days.
Also, installers are still up there cleaning panels. So it could possibly get a little higher.
Have thought about this as well. There are extra supports that came in this morning after the photos were taken. He waited with these until everything else was done as whilst they scurry about between the panels, feet tend to get hook on them and it is very high up there…
Also, I am fairly sheltered from wind. My neighbor behind me takes the full onslaught for wind that comes from the South as he is on hill and higher than me. Also lots of trees between me and him to block most wind. Most of it should pass over me.
Should the wind come from the North, the worst that could happen is that those pillars will bend and push the panels more flat towards the roof surface.
Time will tell of this is merely blatantly ignorant reasoning from me…
Little higher now.
Don’t think I will see 6000W again because of the new angle. When they were mostly flat they were basically perpendicular with the sun.
But hell this is close enough.
Had a spot purpose build for panels. EV tubes. Lekker nice and flat. Red block.
Wind comes from front of house, the blue arrow.
So one day I was speaking to roofers.
The guy asked me if I was aware that the wind coming from the front, going over the pitch, will not push down on the panels on their frames, but could cause a lift like a airplane wing, lifting them …
More concerning, roof being Diamond Deck/Kliplock type (it clips in), better, he said, you put some screw into them frames and into the beams on that flat section.
I refused, it will leak, roof being that flat.
Hence I had the panels moved to the front, smack in the northwester …
My point, 100% referring to TTT and his ideas, I though I was clever, was not so clever for Northwest Cape Storms and what roofs do to wind … I should have asked the designers upfront before I had that cool purpose built area installed.
Maybe I must make it a tanning area …
The Green Circle, that area now has a flat roof, IBNR, my pop rivet roof.
Also why I asked about those frames of yours …
