Solar photovoltaic power generation is to rely on solar cell components, use the electronic properties of semiconductor materials, when the sun light in the semiconductor pn junction, due to the p - n junction barrier region produced a strong built-in electric field, resulting in in the barrier region of nonequilibrium electrons and holes or produced in the barrier region but the diffusion barrier region of nonequilibrium electrons and holes, the built-in electrostatic field, each moving in the opposite direction, leaving the barrier region, the p region potential increased, potential of the N region decreased, so as to produce a voltage and current in the external circuit, the light energy into electrical energy. Solar photovoltaic power generation system can be broadly divided into two categories, one is grid connected power system, which is connected with the public power grid through the standard interface, such as a small power plant; another is an independent power generation system, that is, in its own closed circuit system. Grid connected PV system is converted into high voltage DC by the PV array, which is converted into high voltage DC after high frequency DC. The output of the inverter is connected with the same frequency and phase sinusoidal AC current. The stand-alone power generation system photovoltaic array will receive the solar radiation energy directly converted into electricity to provide load, and the excess energy after charging controller to chemical energy stored in the battery.

Is specialized (focus) on Manufacturing & Developing the Technology of Welding & Cutting industrials.

Along with the China/ Asia shipbuilding industrial developing, Wood Well Limited start to touch the shipbuilding associated biz and products, looks like: BWMS, Cutting Tools, Welding Machine, Pipe, Power Cable,CBM…..

And the industrial field enlarge to: Mold Maker, automotive, Pressure Vessel, Chemical Energy….

In order to strength our ability, we invest and cooperate with some good potential China manufactory on “welding & cutting” from 2007 Year.

 

From 2010 Year, we cooperate with LG, Samsung to agent and sales on China market.

The beginning products is from the Recycle Chemical Resin: HDPE, LDPE, and LLDPE.

Now we have developing the more cooperate field with LG, Taita , Samsung….

 

On 2013 Year, we open the China Independent Corporation in China Shanghai:

Shanghai D&Z International Trading Co., Ltd.

And have the China Representative Office at Dalian, Zhuhai,

And the same year we set the Indonesia Representative Office in Surabaya.

It is enlarge out biz scope from Asia to East-Asia.

 

On 2014 Year, we register the “GSC” Brand for production the welding & cutting materials.

It is widely apply on the industrial fields.

And we set the Japan Representative Office in Tokyo on 2014 Year.

It is help us upgrade our quality and service standard, and have the chance to cooperate with Japan famous company: Kyocera, Toshiba, Asahi….

 

On 2015 Year, we set the Brazil Representative Office in San Paulo.

The 2016 Rio de Janeiro Olympic Games will be hold son, we hope our products and service could win this market.

 

During the last 14 years developing, and all the Wood Well Staff hard working, now we have the 3 main division with 7 Section.
