Just wondering about your thoughts on whether I lost a job to a technically deficient but more expensive design.
Basically a customer has a fairly large tree due west of his roof

but has been convinced that the shading is severe so he should go for a more expensive quote using micro inverters. I've modelled this in PV*Sol Expert and a standard Power One 3.6 out performs both Enecsys and Enphase.
Unfortunately Solar Edge are not on PV*Sol so has anyone done any modelling in PVSYST to see if Solar Edge really do outperform when shading is softer and from a more distant object? The PV*Sol figures only showed 3.6% shading on most shaded panel.
I know it shouldn't but it does get to me when a salesperson convinces a customer to go with a more expensive design that I'm 99% convinced will produce less energy! Happened twice in the last two weeks
I've been in solar for 8 years so if I'd have thought a micro-inverter was the right solution that's what I would have proposed! I do recommend them with hard shading from close objects but in this case I'm sure it's the wrong choice of inverter.
