What are the rules for mixing panels of

Panels in series limit the current to that generated by the smaller panel, voltage is the sum of the panel volts. Thus panels in series should have similar current outputs.

Can I Combine Solar Panels of Different Wattage?

Combining different wattage panels is advisable when expanding or upgrading existing solar arrays with leftover or new panels having different ratings, especially if using advanced

Mixing Different Wattage Solar Panels

The short answer is, yes, you can mix solar panels that have different wattages. But it is not usually advised, because mixing different wattage panels reduces the efficiency and power output.
