Reviews photovoltaic system: mono, poly or amorphous?

[hdesch]

Hello, wishing to install pv panels, knowing that the south facing roof area is 600m² with a slope of 30%, I live in the north of France, and I have a budget 36000 €, what do you advise me as type of panels (mono, poly or amorphous) for a maximum of production?
Thank you

Do not panic, with your budget you can install 6800 Wc in mono that will take 48m².
You also have to see what type of roof, built-in assembly or not, billing in reduced VAT rate or to a taxable VAT.
Given your location, you could ogle the side of Belgian installers.

Amorphous is only interesting if installation costs are reduced.
(Style lay all the bazaar in a day on bins on a flat business roof)

Considering your surface, you can possibly orient yourself towards panels "a little old fashioned" which have a lower yield per m².

Attention, beyond 5 KWc, it is generally necessary to inject in three-phase

Thank you for your answer.
The roof is in black eternity, it will be non-integrated and reduced vat rate.
The installation is in three-phase 380 v.
5.3 € the kWc .... we can do better?
Have a good day

Have a good day

The Wc I presume

Yes we can do better but it is not the subsidies that will help ... I understand!

Well I took an average Belgian price. it is not yet a very large installation. You also have to see what signs have put: Chinese "old-fashioned overstock" or Sanyo HIT ....
I heard this morning that a company Ensival (region of Verviers) had had 500.000 euros installed PV on a metal roof. In fact, if I understood correctly, they glued amorphous PVs that could be unrolled on a rolled steel roof. Big advantage compared to poly and monos: much lighter, no rails.
We must also consider the structure of the roof: Eternit on wood frame, much less expensive than on metal frame.

Make quotes, you'll see.

A Belgian company proposes to me a installation in mono PV Enfinity-185M5 of Chinese manufacture for the price (complete installation) of 4.7 € TVAC / Wc.
It sounds interesting but what should you choose ... hi tech or old-fashioned ...

[elephant]

It is a good price and 185 Wc is very good. Beware, however, the Chinese often sell 185 plus or minus X%, and it's usually less. If you want to annoy the supplier, you require the individual test sheets of each panel!

I'm curious to see what the French will offer you.

[hdesch]

Here are the characteristics of the "Chinese" panels, ... are they valid for the price?
With an installation of 7700Wc the seller advises me a single inverter, is he right?
thank you and good evening

[elephant]

1) the datasheet, it's one thing, the test sheets, it's another

2) yes, if it is a three-phase inverter: beyond 5 KWC, network managers require three-phase feedback., Otherwise, you need 3 inverters.

Is your network a network 230-400 with neutral ????

(which allows to use less expensive "transform less" inverters.

[hdesch]

The network is in 400 v with neutral.
I am waiting for another quotation "Norwegian panels" it will certainly be more expensive but also of another quality ... and more ecological (-of km) ..
