The 440W PV output / 380W inverter output seems be taking into account pretty-normal 90% efficiency, which is practical. What the biface does for you is slightly boost your output in less-ideal insolation, so even though the first face might drop below 440W, support from the second face should keep the inverter at 380W a little longer than it would with only once face, and give you a little extra as sunlight dims further. You'll never get the full benefit of biface (alleged 30% for some panels, so potentially 570W for a 440W per-face?) in full sunlight though, because of the microinverter limit. There's a slightly sad pragmatism creeping into Renewable Energy which means we're happily accepting lower utilisation of components / opportunity *because there's no way of reliably utilising peak performance*. Pragmatism has its benefits, once you've talked yourself round.
Does the inverter mounted on the bacl of such a panel impact the light gathering characteristics?? Would it not be better to ensure all cables and inverters don’t block light from hitting the underside solar cells??
Send me one for free so i can stop polluting air to turn my lights on and save little kids from getting asma if you really like kids you will come and install it for me for free .
Sound like a good idea on paper but it's interesting that lack of modularity is being sold as a positive. Should something go wrong with just a micro inverter, the whole inverter and panel assembly will be 'scrapped' and replaced.. fine from a customer pov whilst in warranty, but there is the downside of unnecessary landfill in my opinion. Further, outside of warranty (yes it's a long time away) then a replacement of the entire unit is far more costly to the end user, so definite negative at that point. Appreciate all the content and in depth technical explanations though!
Looks like the inverter is in a cradle that is bonded to the back of the panel so if the inverter were to go down it could be unclipped and replaced, I think
@@billbobaggings1505 It does put you in an 'iMac component not the same as PC component' position though, unless the cradles themselves are standardised across suppliers - in which case I guess what you really have is a separate panel and microinverter after all...
Lots of good information in this video. Overall, I am generally not in favor of removing modularity even if the warranty is reasonable, the hassle factor of the lack of modularity makes it annoying. Thanks for the video.
So when the inverter fails as there’s always 1 in a batch a few years down the road, time will move on and so do the pannels which by the time may be 500+ with the original discontinued, will they swap the panel with the equivalent as that could be the iq9 or even 10 by then and more than likely higher output solar pannels by then ,as well. given that enphase has with other models brought back and replaced with the iq7 in the past and altered its cabling over time what happens if newer pannels require a different main string cable etc and rest of rig compatibility or just remove the inverter and use one from storage, as if the cable gets altered requing a heavier gage , what will happen to the rest of the incompatible cable run , given there integrated will they be replaced to the newer panel’s as well
Enphase app has ropey connection to its servers for users, often can’t connect with large time gaps in service. I know it’s Enphase as my Alpha battery app works great all the time.
Is there a cost saving to the customer when using these integrated panels over separate REA panels and Enphase micro inverters ?

Are the microinverters and panel made in China?
You saying they're attached to each other in Australia?

Excellent product
Have prices gone up recently?? I did an online quote for 6 panels a few months ago £5k plus scaff
Now same seems to be £7k ??
Excellent news 😊. Enphase gives just great quality, warranty, and customer service.
