PV-Sol treats the sanyos as mono's. PV-Syst accounts for the HIT technology so if anyone is running that could you do us a comparison, i'd like to have this cleared up.
We've done more schott than sanyo, like others have said i'll only use sanyo on a small roof.
Only problem with schott is the stacking system during delivery, we've had 6 panels turn up shattered this year, 4 in November when we really could have done without extra hassle, also still trying to get the refund from Segen for damaged ones we received in JULY!!! Get on with it Segen...
Exactly, its only a 5M square roof, so either 8 normal size modules or 10 sanyo's. So it could be worth the extra money if he gets another 500w+ on the roof!
