Reflections about a remote shortwave listeners station

During the last days I reconnected my notebook - not the tablet - to the solar charger and did some running tests with the 15 W solar panel. This weekend the new 100 W solar panel will be added to the 100 Ah solar battery. It should give sufficient current to run the notebook during night time. I am looking foreward to do this. Due to power reasons I will use the 5 V tablet only for live listening. It remains connected to the 7 Ah battery which is powered by the 15 W panel, or the 20 Ah battery which fits in a pocket and can be charged at my home QTH.
