Ok since a lot of people are asking, I will try to answer. Long thread ahead
PV systems are complicated ones, and there is a lot of internal specs/configs that you need to look for. Suppliers give a very basic offer without any details

If they want you to pay 5k+, they better be able to answer questions. The costumer has the right to get all the data sheets, calculation notes (for estimated PV production, cables sizing, protection devices..). I am seeing quotations of half a page, this is unacceptable 2/n
1- Start with the equipment datasheets, and check on the manufacturer website (some are cheap counterfeit). For the panels look for lifetime and guaranteed efficiency drop. For batteries look for DoD/nbr of cycles curve. For inverters you need to look for a lot of things 3/n
