ACT and L light source received orders for Bhutan solar LED lighting

Japan's Advanced Capacitor Technologies (ACT) and L-Light source announced that they have received an order of US$530,000 from Bhutan, mainly for 220 sets of solar LED lighting lamps using lithium ion capacitors as storage devices, which will be installed in schools in Bhutan. , hospitals and public facilities. It is scheduled to be available from February 2011.

Bhutan will use the $530,000 purchase from the Asian Clean Energy Fund (ACEF) set up by the Asian Development Bank (ADB) to purchase 150 fixed and 70 mobile solar LED lights. Solar cells are purchased locally and are not included in this order. The fixed type is equipped with a white LED with an output power of 2.3 to 4.7W and a mobile type with an output power of 1 to 1.8W. Both models use the large-capacity capacitor "Premlis A5000". Two fixed models were installed side by side, and one was installed on the mobile type. The operating voltage of the A5000 unit is 4.0 to 2.0V, and the storage capacity is 8.3Wh. In terms of the time of use at full power, the fixed type is 3 to 6 hours, and the mobile type is 4 to 7 hours.

The Bhutanese government aims to supply electricity to all its citizens. In the “10th Five-Year Plan” from 2008 to 2013, it plans to increase the domestic power supply ratio of Bhutan from the current 60% to 100%.
