Thanks to the sun !
We started with a small panel that fed only water pump and a connected inverter to the cigarette lighter which allowed us while we were driving to recharge the computer, two phones and camera battery.
But in the summer 2017, we decided to invest in a more powerful solar installation. We made this addition while we were Scotland and ordered to Photonic Universe because the prices were reasonable and they offered delivery in UK. For about 400 €, we bought a solar panel 100W, a gel deep cycle battery of 100Ah, a controller, cables, fixing pasta and a gadget to see sunshine, load, etc..
This allows me to work on the computer all day if I want to, directly to solar and recharge our electrical appliances.
As for the Internet, packages today are largely sufficient to use the phone as a modem. I pay twenty euros per month at Free, j & rsquo; have 100 GB per month in France, 25 Go in Europe and d & rsquo; other countries (l & rsquo; eg Australia).
And of course there is public libraries that offer nowadays often Wi-Fi and have power outlets. Or even cafes, if you consume something there of course.
