The general recommendation is to have 60% of the required vent area as soffit 40% as high vents which minimizes the chance of depressurizing
Setback for plumbing and exhaust vents on noncommercial
I am working on a design where the contractor added plumbing and exhaust vents in the middle of the array area and want to know how far a PV module must be from one of those vents.

Providing Access to Roofs with a PV System | NFPA
The last type of required pathway for venting is where nongravity-operated smoke and heat vents are provided. For those, a 48 in. (1219 mm)
Natural Ventilation and Effect of Temperature on Solar
When the surface temperature of your solar panels gets too high, solar panel efficiency can decline somewhat. Let''s investigate the effect of
Microsoft Word
In the event that a raised photovoltaic mounting bracket system is used over the location of an installed O''Hagin attic ventilation product(s), then we suggest a minimum clearance of 2 to 6 inches from the
Clearance requirements for photovoltaic panels
