grid parity, page-31

Isn't there something wrong with the .333 bit ???

And don't forget the Inverter and Electrical work
Around $ 5,000 on the average.

Dyesol produces 85 watts per square meter per hour
in 1/3 sunlight and more in full sunlight.
Sunlight = 1000 watts per square meter


85 watts
by 6 hours (reasonable average in 1/3rd Sunlight)
=========
= 510 watts per 6 hour day

510 watts by 7 days
======================
= 3.570 KWH per 7 day week

3.570 KWH by 52
====================
= 185.64 KWH per square meter per year.


Having got rid of that, Tas and I use around
6,000 KWH per year at $ 0.250 per KWH which
equals around $ 1,500 .

We would need around 33 square meters of Dyesol
DSC to to get the 6,000 KWH.

10 years power usage would equal $15,000 minus
$4000 for installation and Inverter which leaves
$11,000

33 panels divided into the $11,000 would be
$333 per panel.

So we would have free power after 10 years

Our mate installed quite a large Solar Array a bit over a year ago and claims on his current data he will pay it off in 10 years disallowing the Government rebates.

It is on a angled tin roof on steel framing. So the panels have been laid flat on the tin. So a simple but large system costing around $30,000 before rebates.

He sells the power to Aurora for $ 0.250 and buys it back for the same amount and is breaking even.

Problems
He has noticed the drop on really hot days
Never has got more than 3 hours full output
The Inverter had to be oversized to stop it
blowing up in the 1st year.

Allowing for what he paid and the time he will pay it back , Dyesol will have to sell for around $200 per square meter on top of the tin price . Why go cheaper ???

Grid Prices can only go up, and there was a Chinese Govt announcement on TV today (CCTV) that they are going to bring in a carbon tax
