How would you design this?

[smiffy_99_uk]

I Have a Customer adamant that they want a 6 panel system with 3 on a south facing roof and 3 on a east. I Know normally on south and east you would either use dual mpp tracker or two inverters. I cant find anything small enough for two or a mpp tracker for this size. Any input would be Appreciated.
Many Thanks

x2 Soladin 600?

 

[daytona600]

6 modules of what Wp ratings
2 soladin 600s 2 steca SG300/500 or 6 micro inverters
all low effciency as per all micro/small inverters
or has client room for thin film modules - higher voltages to suit min range of the MPPT

I was thinking of Sharp 245's because of the small roof space but now I am thinking about Sharp 230's to fit a Soladin 600, How would you find the annual yield with these small scale inverters?

 

[daytona600]

check mastervolts website to see if modules will work
all small inverters have limits on volts/amps
yields will power a big plasma or a microwave oven
not very good units cheap from china
google mastervolt soladin recall

I see your not a fan of small scale inverters have you tried thin film? do you think its would produce better results?

 

[daytona600]

thin film in stock , but need more surface area , great for any inclination and orientation
good for shading and east/west/north as well & low light

all micro/small inverters are low effciency and limited in application
modern string inverters to 4kwp are 97% effciency and universally flexible in application
plus i am still waiting for a credit on some soladins i returned under warranty
mastervolt recall website blamed component overheating
the last thing you need in any electronic device is thermal run away
or as the client would call it - my inverter went on fire
thats what you get for transferring european production to china and fitting cheap components
PM send on options

My Inverter went on fire are not words you want to hear are they ? Thanks for the PM. All looks very interesting. Still scratching my head at the mo about this one.
