Scaffold? Show me the solar installer who has a scaffold set up for two people for one day. That might be charged, but in the end, the long ladder goes onto the roof.

Our neighboring house just got a photovoltaic system last week and a scaffold was set up for one day.

The invoice still lacks the aluminum substructure, the mostly used stainless steel holders and screws, the cabling and RCBO switches, all operating costs (variable and fixed) that are proportionally allocated, wages, taxes on profits, travel expenses, administrative costs of the order, warranty coverage, etc. It is clear that some black sheep pad their pockets with inflated offers due to the extreme demand, but anyone who perceives €1,500/kWp as "rip-off" should also stop using liquid soap and buying bread rolls at the baker’s.

Does anyone have current costs for tile laying? I checked; in 2017 we paid 66 EUR / m2 all-in for laying floor tiles, including consumables and labor, but excluding the tiles themselves. Currently, we are waiting for quotes for 36m2 of floor tiles.

I just got 2 solar modules at the factory outlet of a photovoltaic manufacturer. 0.82 kWhp for 260 EUR. 0.21 kW/m², not particularly good... not particularly bad... a usual value. For 10 kWp you would have paid 3,200 EUR. Of course, you still need an inverter (SMA Solar 10kWp 2,100 EUR) and a 2-man team working on the roof for a day (hourly rate 120 EUR*2*10 hours = 2,400 EUR + travel 300km*0.5 EUR/km = 150 EUR)…

So. 3,200 + 2,100 + 2,400 + 150 = 7,850 EUR. We round up to 8,000 EUR and ask ourselves where the remaining 7,000 EUR go.

Because neither does a solar installer charge 120 EUR/hour for his journeymen... nor does he buy the modules at the price of 130 EUR/0.41 kWp... nor does he pay the SMA Solar Internet price for the inverter...

At least that’s what I assume. Because my craftsman buys his stuff from the wholesaler at good prices and not at Obi, Hornbach… or in the sale at the photovoltaic manufacturer’s factory outlet...

Oh right. I just read… 15k net. So we don’t ask where the remaining 7,000 EUR go. We ask where the remaining 10,850 EUR go. Because we already paid the VAT. We got the modules at gross prices, the SMA inverter as well. And the 2-man team also likes their salary gross…

For the electrician, you can calculate between 1,000 to 2,000 euros depending on the effort. The salesperson (often freelance contractors) typically takes around 10% of the net amount. On top of that administrative costs such as storage, marketing, vehicles, chamber of commerce, business tax plus provisions for warranty, scaffolding contractors. And of course the scarcity surcharge, easily recognized by the waiting times for installation....

I just picked up 2 solar panels at the factory outlet of a photovoltaic manufacturer. 0.82 kWhp for 260 EUR. 0.21 kW/m², not particularly good... not particularly bad... a typical value. For 10 kWp, you would have paid 3,200 EUR.

So. 3,200 + 2,100 + 2,400 + 150 = 7,850 EUR. We round up to 8,000 EUR and wonder where the remaining 7,000 EUR go.

Because neither does a solar installer charge 120 EUR/hour for his journeymen... nor does he buy the modules at the price of 130 EUR/0.41 kWp... nor does he pay the SMA Solar internet price for the inverter.

At least, that's what I assume. Because my craftsman buys his stuff from the wholesaler at good prices, not at Obi, Hornbach... or in the sale at the photovoltaic manufacturer’s factory outlet.

I'm currently reading... 15k net. So we don’t ask where the remaining 7,000 EUR go. We ask where the remaining 10,850 EUR go. Because we have already paid VAT. We bought the modules at gross prices, the SMA inverter too. And the 2-man team also wants their salary gross.

Well, I would get 25 modules with 405kw. The module at 250€ each plus 90€ shipping on eBay is already a good price. How you come to 3,200€ for 10kwp is not clear to me. Where can you buy such modules?
I am very satisfied with the price. The inverter costs just as much, only the delivery time is extremely long.
Otherwise, the offer naturally also includes the material and installation. I leave such things to the experts. No force on earth could get me up on the roof.

I want to have your modules. With 405 kW per 250€ module, I would compete with the municipal utilities.
