Hi Tim
The green algae is forming because of the absence of (normally) sunlight, which stops the build up naturally. I have also heard from some of our customers that parking the caravan close to the house wall (especially if it near the central heating boiler exhaust where there is a regular supply or warm damp air) makes the problem worse.
Solution (not sure), wash your vehicle with Fenwicks Caravan Cleaner;
