For actual comparisons, you need to look at manufacturers prices at
source, over time.
The retail price is affected by things like the exchange rate, current
wars, oil prices, and materials costs.
And whatever retailer you happen to look at. +/-30%
Exchange rate. +/-30%
There are all sorts of trends, online, for things like this.
Whenever you see a price on a valid tracking/trending site, the cheapest
retail price you are going to get, is about the same as lowest
manufacturers price.
Ex.
If the current price of PV is 0.50€/w (it is, about, in the EU, 20%
VAT/IVA tax paid), the lowest priced PV panels will be at about this
price, within a few percent.
Big boat stuff goes for costs+margins+opportunity costs, as does
anything in the capital goods category.
Basically, anything costing more than approx. 3000$, or pallet sized,
can be had at low margin from some trader somewhere, and the cost
approaches the real value.
Transport costs are near zero, including internationally.
Anything quoted as extra is either "brand", "marketing or "valua add"
meaning you often pay too much for nothing.
But sometimes not- the onus is on the buyer to knwo what they actually need.
In boat stuff, systems integration may cost upto 400% of value of the
goods themselves, on top.
This may or may not be good in engineering terms, and may be good value,
or not.
Examples.
1.
Thus, a "yacht store" buys an "x kit" at 1000$ (landed).
They slap their brand on it (+1000) and 50% margin on it , so
(1000+1000)*150% = (3000$ + installs and systems) * 200% == 7000$.
2.
I buy the kit at 1000$.
I install it, using 500$ in tools (that I have) and 2 days time and a
rented winch (200$).
Total costs (to me) 1200$.
3.
The fisherman need the new piece for his fishing boat and call me to
have it ready at time "nn".
I charge 2000$ for my trouble (2 days) + my costs 1200$ = 3200$.
Fictional example, but describes how the systems work.
