The efficiency of solar cells is not large enough but still far

Approximately 11% of solar energy is absorbed.

Intensive research and development work is in progress. Sometimes they wonder why they have not gone and why products are not mass produced.
One example is that the knowledge of the orientation towards the sun increases as the panel can charge significantly. Why is not a steering mechanism that is always addressed in solar cells right?

Although the rather primitive stage in the photovoltaic industries, today, in enough the approximately 11 percent good to provide the energy needed. They are betting that create power-efficient solutions for supplying weather stations, broadband equipment investment, which lacks 220volt, in the archipelago in the mountains or where it sometimes becomes loose power.
