[RE-wrenches] Panels with 20.1% efficiency rating?

[Marco Mangelsdorf]

Looks like Silevo—which was consumed by the SolarCity juggernaut—makes (past tense?) 18+ percent efficient mods.

 

See attachments.

Speaking to the U.S. market: I've been a SPR dealer 3 different times (on again, off again, currently on). Because I have to bid against non-SPR systems all day long I've had to do my homework on this issue. >From what I've read in the literature, there are no commercially available mods that are in the 20's except SPR. Other high eff claims are cell eff or non-commercial/space tech stuff. Too bad. Can't wait for solar R&D to break the ceiling and reach commercially viable efficiencies in the 50's at least.

If you ~really~ need high efficiency solar panels, you could go here...

Greater than ~30% efficiency if you don't mind paying about  $250 per watt.

Hey Marco,

I pulled the data sheet to scan it and what did I see? CELL efficiency is 21.1%, not module efficiency. I guess I told all my customers wrong....sheesh! 

I will email you the data sheet.

Right August, it was the Panasonic HIT 240 that is 21.1% . The newer ones are less.

Hi Lou,

 

The LG Mono X NeON 305 W 60 cell is 18.6% according to their website. I think that is about the best non-SunPower option you can readily get these days.

Even Panasonic modules  are only 19.4%: http://eu-solar.panasonic.net/en/products/n-240-n-245/

 

Best, August

Wrenches,

 

I am looking for panels with a 20.1% efficiency rating or better, that are NOT Sun Power. My distributors can not acquire anything even near that. Any leads or resources to check would be greatly appreciated. 

 

Thanks! 

 

Aloha,
