In the sub/tropics, usually there are only two seasons: wet and dry. During wet season, how much is PV production affected?

Generally you get less than 1/3 of ideal conditions during rain. Overcast less than 2/3 of ideal.
In Hawaii, each island has a dry side and a wet side. You can site grid-scale solar on the dry side.
My understanding is rain/clouds don't drastically affect energy production, and sometimes the first rains can work to clear some dirt and debris off.
