Yield comparison of photovoltaic installations worldwide

Postby Retrerni » 02.01.2013, 01:53

Happy New Year all together!
As the change of years usually is also the time to sum up the year that passed, I'd like to also start that here regarding PV yields all over the world.
The basis of the comparison is the yield of the plant (in kWh) of the corresponding period divided by the nominal size of the plant (in kWp). This will naturally show huge deviations across the world (and also in between two years), but what I'd like to achieve with this thread to show what's possible where and maybe also at which costs. It is not intended to compare two sites next to each other where one is 1% more efficient than the other...

Just some kind of randomly picked samples (all static plants, to be continued (by everbody)...):

Northern part of Germany: daily average 2,4 kWh/kWp
China(Jiangsu): 2,5 kWh/kWp (best month daily average: 3,52 kWh/kWp, worst 1,48 kWh/kWp)
Great Britain (Gloucestershire): daily average 2,7 kWh/kWp (best month daily average: 3,8 kWh/kWp, worst 0,57 kWh/kWp)
Southern part of Germany (A/Bavaria): daily average: 2,85 kWh/kWp (3,0 kWh/kWp in 2011, )
USA/Canada (Great Lakes region): daily average 3,57 kWh/kWp (best month daily average 6,07 kWh/kWp, worst 1,05 kWh/kWp)
Greece (Rodos): 4,12 kWh/kWp
Border USA/Mexico (Arizona/New Mexico/Texas, still with potential to improve...): daily average 5,3 kWh/kWp (best month daily average: 6,1 kWh/kWp, worst 4,17 kWh/kWp)

Everybody knows that Germany has been the leader in the photovoltaic industry even regarding installations for several years, but why do others were so restrained regarding investment into PV?
Now as one can see that yield deviation near the equator has of course a huge impact but still the continent has a huge impact as well. E.g. when in the southern parts of the US about double amount of kWh could be produced by kWp. than in Germany. So what would the yield be in a county like Bolivia then?
What makes installations in the different countries so difficult?
Is it limited by local legislation?
Are subsidies of conventional energies (coal, oil, gas, nuclear) much greater?
Is there a high local ignorance about renewable energy and/or environmental issues?
Is it driven by the educational background of the average citizen?
Is it still not known to a board variety of people?

Hopefully some people will add data from their home countries to this thread as well.

Happy New Year!!! I have a table with kWh/kWp values in this file. Go to the "Index" page which is the farthest tab on the left and follow the hyperlink to the "kWh per kWp" tab. The spreadsheet details the sources for the values and the assumptions used.

Re: Yield comparison of photovoltaic installations worldwide

Postby Retrerni » 11.01.2013, 23:58

Nice list, eleh, thus I did not download the file as one seems to have to register for it.
Is that data from real plants and from last year or the average for several years? As e.g. the value you quoted for at least two cities has been superseeded by aboutu 12% last year.

Ciao

You have to register? No wonder nobody downloads my files. Pity... Try here.

http://www.wind-works.org/Solar/Economi ... sheet.html

I publish an updated version every month at the link on the index page.

Most of the data comes from PV Watts which uses a Synthetic Weather data set covering 20ish years. The assumptions I used were a latitude tilt and a derate Factor of .8 rather than the standard .77.

Hi eleh,
thanks for the comprehensive list. So I understand this right, these are simulated results, not real yields from actual installations?
best regards

And my intention was to proove those simulated ones with real ones like those I listed. At least for last year the simulation stayed below real yield and thus is realistic and conservative.

The data in my spreadsheet is average weather over 20 years. I use the data for simple modeling. A more rigorous approach would be to use the underlying Typical Meteorological Year (TMY) weather data in a statistical model that simulated 30 years worth of random weather that went up and down year by year but averaged out to your TMY input. I've built a prototype model that does this - my model doesn't quite work but it comes close for a hobby project.

You wouldn't want to use one years worth of performance data (even real world data) as a benchmark. You'd want to use many. Note also that your data may not come from a system with the same tilt and orientation as my data. I'm not saying my data is better than yours - I'm only saying my data is likely a good benchmark for simple modeling.

A neat way to benchmark expected system performance would be to use real world data like yours from many systems over many years in a compact area. That would be ideal really. Eventually there should be enough people sharing data to make this work.

Here's the file I've been trying to share. Can anyone confirm if this download works?
