On electric adventure to Norway

Zoe rainbow Denmark[Klik hier voor de Nederlandse versie]
Two years ago it was the first time I went to Switzerland with my 100% electric Renault Zoe. 900km one way was a real challenge because back then there were no fast chargers. It made me happy if there was a semi-fast charger (22kW) on the route. This way I could not drive more than 350km per day. The next year there were some fast chargers and it was possible to make an entire tour of almost 2400km through Switzerland.
This year I set the bar higher, and the outward journey is already 2000km! Now I will mostly use fast chargers, and cover 550km per day. Seven different charge cards or phone Apps have been arranged. Hopefully they all will work, because I wasn’t able to test most of them. Furthermore, I will not use ferries on this trip, but drive entirely over bridges in Denmark and Sweden to Geiranger (Norway), where among other things I will attend the 20th anniversary of the Norwegian electric car association.

My Solar Panel System of 2940 Wp

20090430-zonnepanelen_On April 29’th 2009, finally my solar panels are installed! 14 panels of 210 Wp (Watt Peak) each (Suntech STP210-18/Ub). In total 2940 Wp (Watt Peak). Not a small one. Especially if I tell you that my last year’s usage in electricity has been around 1600 kWh. That’s why I bought it also for the future. If I had an addition to the family, and an electric car! My choices: Hybrid plug-in, or pure electrical, depending on what models will be available. But I will write an article about that some other time. Now more about this installation…
