1. Introduction

 Solar power is an infinite power, for its clean, quiet and security, it has become the main power to be used for human being in 21 century. Solar panel is a high-technology production, which is all advised by government because it is once investment and long benefit. This production is widely used at the far zone without electric net, and the open work zone, such as dwelling house, communication, hydrology, geology, mine, farm, orchard, and breeding farm.
The solar panel of WBT series is composed of high quality silicon-crystal light-electricity receive system, huge capability save system, and reliable adverse change output system, which is a high-technology integrated production including electronics, electric-power, micro-processing, auto-control, storage-electricity, and photo-electricity. Solar power is transformed to electric power to save through light-electricity conversion; by passing the deflector, it is transformed to all kinds of DC output which is at user's request.
