Without pictures hard to tell...
I suggest to call a solar company and run a full "health check" on the solar tubes.
Also,ask them to introduce the system to you such as basic checks, parameters and "what if" scenarious.
Solar tubes are fine for 9 months of the year.
Dec,Jan and Feb we're getting minimum output from the Solar due to angle ,position and length of the day.Think about as a "lunch time" for nature and for your tubes. Now is the perfect time to do service on them as warmer days will make it very difficult.
You can see my system live here:https://www.vbus.net/scheme/3a2d0feae70e6ff873aaaf72aec7fea2
Rarely reached over 15" these days.
Come March,gettting better and from end of April until end of September never have to turn on the boiler or immersion.

Thanks so much, this is really helpful.
I'll look at getting someone in to check out the overall system; it sounds like you said, that this is a side effect of the weather.
If you were eyeballing it, what pictures would you need?
