Nokia Solar Powered Phone - Nokia's Mobile Phone Solar Charging Project
Nokia has recently finished its scientific research on the feasibility of harnessing the Sun’s energy to power a mobile phone with disappointing results.

The Finnish tech giant concluded that charging through solar energy has several but minute benefits when a lot of sun is available, but the outcome was otherwise more ineffective in regions with less sunlight.

The Nokia solar-powered phone experiment dug into the possibility of using solar energy as alternative electricity in areas with less or vague power supply.

Of the five prototypes with solar panels as back covers, two visited the Arctic Circle, one flew to Kenya, one went to southern Sweden and one sailed on a boat in the Baltic Sea.

“The tests showed that charging a mobile phone by simply using a solar charging panel on the back cover is possible but challenging,” wrote the company in a post on Nokia Conversations. ”When carefully positioned, the prototype phones were able, at best, to harvest enough energy to keep the phone on standby mode but with a very restricted amount of talk time. This means there’s still some way to go before a workable and care-free solution is achieved.”

The obvious immediate winner was the prototype in Kenya, an African country known to have plenty of sunlight while the other four handsets had mixed results.

“The greatest amount of charge was generated in Kenya, as there was no shortage of sunlight and the phone tester, Amos, who works as a security guard, was often stationary,” added the firm as it painted a rather bleak picture of the experiment.

Nokia found that other factors were also at play and not only the lack or abundance of sunlight and other weather conditions.

“The amount of charge generated for use by the phone is not solely dependent on the weather conditions and the amount of sunlight. Factors such as lifestyles and the angle of light also have a significant impact on the amount of charge generated,” Nokia added.

According to the company, it was hard to increase the amount of charge with a fixed back cover size, automatically limiting the power delivered to the battery.
