    good question, its a sealed loop system I suppose you could drain it and add some fresh antifreeze to the system.

    I would expect manufacturer details and serial numbers on the panels. Which means you can trace recommendations via this. Phone, email or Google this.

    You should have the installation and operating details somewhere, and I suspect any servicing requirements will be listed there. Over to you here.

    I am a building bod, not a panel installer but have vague recollections about panels loosing pressure, and glycol (yellowy green) antifreeze certainly breaks down with time. This has always been an issue with cars which is why anti freeze renewal is every three years typically. Modern anti freeze is non glycol, and hence longer lasting - the pink stuff you see in cars. Only you will know what was fitted in your panels. Regardless, at some stage this anti freeze will need renewing.
