RCD keeps tripping in rainy weather since having PV system installed

The technician is incorrect. It is almost certain your PV inverter is transformerless, meaning there is no isolation between the grid and the PV panels. The result is PV leakage currents can indeed trip an RCD though inverters are supposed to check for and fault if such leakage exists though this feature can be disabled.
