I'm not saying the opposite. It's just ONE solution. Me personal network injection does not interest me so I do not know more than that. I proposed this solution while waiting for someone to find out whether or not an individual can install this kind of system himself.
Many installers will necessarily refuse, especially the larger ones. But there are also a lot of small electrician craftsmen who have the amenities and with whom it is much easier to get along.

Because that implies that we must already prove that there is a drop in production, then find where it comes from, possibly which panel is defective. And if we managed to isolate the lame duck (s), we must proceed with the exchange under warranty.
And what do you think you will be told in 20 years? Well, my good sir, it's that your panels have been around for a long time since we don't make them like that anymore and we no longer have any in stock, so we just have to leave them on the roof and unplug them.
For the 2-year warranty on gear, you must ensure that it is a manufacturer's warranty and that it is applicable in Europe, which is not always the case for gear that comes directly from China, without passing by an importer / representative of the approved brand.
I believe that the subject has already been mentioned in another subject, and that we had concluded that except for some very large manufacturers, these guarantees are "bogus".
It should rather be taken as a technical data, a bit like an MTBF suitable for solar.
When an engine manufacturer indicates an MTBF of x thousands of hours, that does not mean that it guarantees that this engine will effectively operate this number of hours without breaking down.
And frankly who knows where we will be in 20 years? if it is on this date the solar panels will cost 0.1 € / Wp and we will completely laugh at this kind of guarantee. Maybe even those bought this year will be so obsolete that they will be taken down long before that date.
On the other hand, the 2 year warranty is a real warranty, since it is not that of the manufacturer in Asia, but that of the reseller in France indicated on its site.

It's for you to see. Either we favor the price, or the brand, but it seems frankly difficult to have both.
I already bought from him, and the panel that I took out the indicated power. Maybe I was lucky (we'll see soon, I bought 6 more today for another project)
I report this here for information, just to have a basis for comparison. Let those who find it better and / or cheaper let them know.
Anyway we can not say that this CGP packs a lot of people ... for the moment there are 4 of us talking about it and nobody shows an intention to buy.
For the moment, concretely, we have this:
180Wp panel at € 388 including VAT (19.6% VAT) can be removed in France.
It is at worst the maximum price that we will have to pay provided that we take a good hundred.
If there are more of us and / or we find a better supplier then the price may drop further.
Who takes it? how much ?
