It's not to big , 14x240Wp should nett produce about 2900 Kwh a year.
Which is about the usage i have now.

My neighbour, family of 4, wife has hairsalon, has installed about 40ish panels.. laying flat.supposed to be 10000 Kwh worth..
Mine are angled up.. I think their installer was taking shortcuts. My wires are all nicely tie-ripped. panels up right, wires nicely plugged through wall with sillicone kit, theirs is sloppy.. no tie rips, bare wires,no tube.. and all the panels lay nearly flat, just the low angle of the roof.

already noticed that their panels have a lot of dust on em, it doesn't blow off, won't wash off because of the shallow angle.. dust and dirt is no good for efficiency...I doubt they will see their 10000 Kwh a year
