Nokia Solar Charging Results Came In, Still Not a Viable Technology

Nokia has been testing for the last four months a Solar-Powered mobile phone prototype called Lokki. The phone was given to five test subjects living in different climates: from the Arctic circle, all the way to the sunny Equator in Kenya. The goal was to collect data and analyze how viable this technology is for the mass market. What they discovered is that solar charging is possible, but very challenging. Results were mixed among the test subjects: not only where a user lives, but also their lifestyle and how they use their phone determine how useful this technology could be for a certain individual.

However, talk time was very limited. Only one of the Lokki devices could have supported un-interrupted communication; it was a Lokki sailing the Baltic and constantly being hit by the sun rays. Other devices such as the one in the Arctic harvested enough energy for only 17 hours of talk time on an interval of 65 days! In conclusion, there’s too many variables such as lifestyle and region that influence the effectiveness of a solar-powered phone, which means that depending on those conditions, a solar phone could range anywhere between being useful, to being useless.

The Lokki is a modified version of the Nokia C1-02, a very basic phone without any of the features smartphone users are used to. This means that solar-powered smartphones, which demand more battery life for advanced functions such as high-speed mobile internet, GPS positioning, and advanced applications, are still far away from hitting the market.

    A friend of mine suggested that to the Sustainability department head at Nokia during Nokia World 2010, but as you can see, no devices have been announced. I guess it’s not suitable for phones, can you scroll through a contact list without the screen going black-white every second?

      The refresh rate could be somewhat problematic but can be overcome by simply making pages in the UI instead of scrolling lists.  The bigger problem is that renewable resources r&d is a money sink and it seems everyone wants a way out to make their stocks perform a bit better.
