Solar hot water panels require a cylinder, but it is possible to use them with a combi boiler. This video explains how it works. And for those who prefer to read the information, here's a summary:
If your combi boiler accepts pre-heated water (some do, some don't, it's important to make sure yours is the former), you can have a pressurised cylinder fitted on the incoming side of the boiler to preheat the water. This means the boiler doesn't have to work so hard.
It's very important to make sure the combi boiler is compatible before attempting this. It has to have temperature-rated components on the incoming side and it has to be fully modulating to ensure the water isn't overheated as it goes through.
Once the solar heated water gets hot enough that it doesn't need further heating, it can be set up to bypass the combi boiler, and go direct to the taps.
