Makes sense now. Thanks for the info.
So far, I have found this 30VAC, 1A SSR from Panasonic as the best fit.
(1A should be enough for 2 solenoids; my RainBird DV-100 have an in-rush current of 0.3A then stabilize to 0.23A)

But SSR prices explode even for small voltage/current increments. Maybe it’s not yet the time for SSRs…

My other option is using MOC3063 + the same BT1308-600 triacs. More components but way better specs and price than the SSR.

We are currently away till Monday July 21. Orders placed during this time will be shipped on Tuesday July 22. Thank you for your understanding!
