Is a sailboat will use a motor if there is no wind? No! Same for us, we have solar bikes so we do not want to plug our batteries at the hotel each evening. We took this decision before the departure and we have the strong will to keep this choice till Astana.
This choice obliged us to change of itinerary to get more sun and avoid too much rain. It also obliged us to use more human power, but after all it is also a sportive adventure. We do more breaks than forecasted but each ray of sun is important so we stop and open our second panel to optimize the charge of our batteries. For example I’m writing this article in the middle of the Croatian mountains during a “sun break”.
