Duke Energy completes 10 MW Black Mountain Solar Power PV project in Arizona

We need more data to analyze the average efficiency of projects in today's use. This one points to modules having on average 238W of power. http://www.solarserver.com/solar-magazin…in-arizona.html

SunPower 7.5MW in Phoenix

22,936 modules, for 7.5MW, average looks like 326W per module, tile system so I am not sure what module size. http://www.pv-tech.org/news/sunpower_ins…n=news-rss-feed

Interesting numbers. If I was a homeowner and putting up panels on my roof, I would ask for Renesola panels. They generate more electricity, they degrade less, last longer, and cost less. IMO, Renesola has the best technology, best wafers and best panels out there.

Their E20 is 327w. The area is similar to a 6x60, but ratio differs a bit since its 5x96. If you look for powerful cell tech, here it is. Still much higher cost than standard products. Cell efficiency 22%, module efficiency 20%.

This is an exciting threads that should continue. Another great SPVI thread.

Yes, that's consistent with the average I've modelled for Trina's volume production.

Having large loads of unallocated inventory ready close to end markets might not be a good business symptom though. It is for their ability to provide good service. But these delivery schedule performance things mean more during times of shortage.

odyd, I think that's a good idea; to track actual power rating when we see them. Big projects, big orders, big export shipments. Then we have some hard shipment data on conversion efficiency (even if not comprehensive) that we can verify our assumptions about average panel quality against.

That is the intend. Companies now more so are willing to tell amount of modules and even the model number. So extracting the averages is easy. On the other hand Solarzoom folks were not interested in making this calculation available on monthly shipments. They have simply stated that the cost of performing this activity outstrips the earnings/interest factor. So I dropped the subject.

I find it very weird that Trina comes out with that press release now since that project was built in april to september and commissioned in december. As of october there's not FIT in germany for utility projects over 10MWp, so all the big projects had to be built by the end of september.

Trina is like that. I remember the announcements of their Colorado Springs and Austin Texas projects, which at the time were near record size in the US, were released via press releases after completion and after they were up and running. There had never really been any mention prior. I suppose that is fine and indeed better than releasing a bunch of LOI type of announcements. As for German FIT, I guess we will see what happens as far as further large scale development without subsidies.

Ok, thanks trying to get these export data details though. After a while with project announcements, we should get a good picture of the average conversion efficiency at least for the project market.
