Panasonic donated 4,000 pieces Solar Powered Lantern to Iwate, Miyagi and Fukushima prefectures, hoping that they’ll help add a bit of comfort and assistance to those who have been hit hardest by the quake.Panasonic states, “One of the models also include USB output which can be used to recharge mobile phones. We hope that the products will be able to bring light in midst the situation, especially where electrical supply is still limited. Panasonic Group and its employees sincerely hope for swift recovery of the people and areas affected by the disaster.”
A solar Lantern is produced of three essential elements – the solar cell panel, the battery and the lamp. The procedure is really easy. The solar energy is reformed to electric energy by the solar cell panel and put in a sealed maintenance-free battery for later apply during the night hours. A single charge can work the lamp for around 4-5 hours.
