Highest Output Power per Unit Areas NU Cell Series are made of single crystalline silicon solar cells which has conversion efficiency of 21.5%. It is the most advanced solar cell in the present world market which is supplied by SunPower Co. from USA. - Low Reflection & High Absorption on the Exposed Surface. The metallic electrode is treated on the back side of the solar cell, and the front exposed surface treated with special film for low reflection & high absorption; and therefore, it can be enhanced the electric power generation from the sunlight. It can be used camouflage in military mission. - All Solar Panels are Connecten in Parallel. Normal operation is performed without any coltage variation, but only with diminishing current generation even the solar cell module is partially damaged or shadowed in the parallel connection mode. The amount of diminishing current generation depend on the degree of damaging solar panels. - Flexibility of Power Generation by control of Number of Panels. In field operation, NU Cell cover the any kind of portable electric devices for military mission. NU Cell can be easily adjusted the power including operating voltage and current by modification of number of panels in parallel and serial for need of load power. - Available Any Time, Any Where, Any Body NU Cell is provided an internal battery, if it is sufficiently charged, it can be assisted its operation any time and any where without any light source. It is also very convenient and easy everybody be use it.
