PVSol results request

[digital48]

I'd be very grateful if someone could run the following through PVSol for me and let me have the results.

Two strings
14 x Canadian Solar CS5A190M facing 20º south of west (roof slope 22º)
7 x Canadian Solar CS5A190M facing 20º east of south (roof slope 25º)
both feeding into an SMA 4000TL.

The installation is in Leeds.

Thanks!

As soon as I get some time, I'll run the systems through.

DO NOT QUESTION THE WISDOM OF PV SOL (tm) DIGITAL48, THE COMPUTER IS NEVER WRONG!!!!

COMBINATION IS BAD. INSTALL SUNTECH OR SANYO, IT WILL THEN BE GOOD!!!

 

[digital48]

Tell me more? What, in particular is 'bad'?

 

[SolarCity]

Nothing wrong with the set up as far as I can tell.

You'd need to set up the 7 panels on one string on one of the MPPTs and 14 panels on two strings on the other MPPT. The 14 panels together would give a voltage beyond what the 4000TL is happy with.

Thanks. Now I've double checked, it is 7 + (7 + 7).

@zeljuga: is that what was 'bad'?

@MorganPVI: What's wrong with the combination that Suntech or Sanyo would fix?

 

[SolarCity]

Sanyo or Suntech would certainly increase the yield but the problem is that Suntech are a nightmare to get hold of and Sanyo are a lot more expensive.
