Each panel is wired to an optimizer, then the optimizers are connected in series strings as per usual

As Gavin says: in summer it won't matter.
But with low sun in winter (or early/late in the day at other times of year), the difference in angle will make a big difference to panel output, so the bypass diodes will be working overtime.
By my reckoning, a 5-degree difference (35 v 30 degrees) in angle affects as follows:
Mid-day, June sun: 0.5%
Mid-day, March/Sept sun: 5%
(comparable to morning/afternoon summer sun)
Mid-day, December sun: 20%
(comparable to early-morning/late afternoon spring/autumn sun)
Busy week... The installer has come back saying they will install the quoted GroWatt inverter, use fire retardant board etc.
I am going to struggle to get out of a signed contract where they have offered to comply with the contract.
Whats the worst that could happen with
Growatt 3600MTL (2 MPPTs)
12 x 245w panels on a 30% roof
4 x 245w panels on a 35% roof
Could be wired 8+8 according to Growatt tech support, though that was before I knew about roof angle, and they haven't answered my recent question.
In another thread, FB said
Will that amount to much over the year?
Is bypass diodes working overtime a big problem?
Thanks...
When did you sign the contract as you have 7 days cooling off period
