Hi,
I’ve been reading about solar panels and different approaches - buy ready made, make your own etc and there’s one question I’m not able to answer or find an answer to - why are the ready made ones so expensive (smallest from £800)?
For example:
you can get 36 solar panel pv cells for around £40 on Ebay:

That’s about as many as you get on a standard ready made panel: http://www.solargadgetstore.co.uk/solar-power-station-60-w.html
next thing you need is a battery to store the power. If I’m looking at the right thing, then the prices start around £50 for a 12V battery:

then there’s some wires, a skeleton / rack to hold the panel and some circuitry.
My guess is that most of these things are made in Asia for a fragment of the cost they are sold for, so how does the final price amount to £800 and more? Fat margin? Freight costs?
if anyone can answer this, that would be of great help.
thanks.
this is the £800 ready made set I’m referring to:

It’s DIY, so no labour in the price, it’s pretty much only the parts I described.
You can go to a hardware store for the wire and parts for the frame.
You can use a automotive or marine (Deep Cycle) battery.
You will need a 12v power inverter to power your ac devices.
The real expensive part is the solar panels themselves. Unfortunately is is costly due to the manufacturing process. The end result is when you add up everything, you are paying twice to three times the cost of purchasing the electric from the electric company.
