On the evening of September 25, eight group teams and 16 individual competitors after an intense elimination resulted in four teams and eight individual players. On the 27th, the competitors gathered in the billiards room for another round. After two hours of showdown, two group teams defeated the others to enter the final champion challenge and two individual players entered the finals.
On the 29th, the teams and individual player finals match began at the same time. Every player showed their strength and will to compete.
The victory or defeat of the competition was not the issue. ReneSola hopes that its employees who enjoy sports will participate in future company sporting events, such as badminton, ping pong, basketball, and others.
ReneSola exhibited on November 19th to 21st at ‘Strategies in Light’ in Munich, a conference and exhibition mainly focusing on LED lighting technology. For the first time, ReneSola has shown its outdoor and indoor luminaires to a wider audience of trade experts in Central Europe. As ReneSola is dedicated to large to medium scale projects in the public sector as well as at facility lighting, we have focused on street and tunnel lighting as well as on indoor lighting. For the latter, ReneSola concentrates on products dedicated to facility managers such as, LED tubes, high bay lamps, and down lights.
Being a rapidly growing market, and being a provider of direct benefits to consumers’ energy bills, more and more people are taking the plunge into residential solar energy to power their homes. However, prior to officially adopting this method of power for a residence, it is first vital to understand exactly how these solar systems work to generate power.
There are three essential components to the system: the solar modules, the inverter, and the utility meter.
In today’s world, the fast economic development has resulted in the serious depletion of nonrenewable resources, such as oil, coal, and natural gas. The energy crisis is increasingly prominent and the use of traditional energy sources has created a pollution issue. Increasing pressure to be environmentally friendly has made ‘Save Energy and Go Green’ an important issue in society. The energy and environmental crisis has led the energy industry to actively search for new developments. The solar industry promotes ‘Green Energy’, receiving recognition from all regions of the world and leading to rapid development. Similarly, the production and use of Light-Emitting Diodes (LED) in the lighting industry and its energy saving and environmentally friendly features have brought about great development in this technology.
Solar energy relies on solar cell components to generate electricity. Solar cells are made of silicon that acts as a semiconductor. Heat and radiation from the sun’s rays hit the silicon cells and release electrons that roam freely. The roaming electrons in the cells are channeled into an electric field. Metal strips on the bottom and top of the cells allow the output of electricity. There are two general types of solar power generation systems. One type is the Grid-tied system, which is connected to the utility company and works like a small power station. This system uses solar modules to transfer solar energy into direct current electricity which is converted into alternating current electricity by the inverter. This electricity powers appliances, lights, or other household items. Another type is the Stand-Alone system where the solar modules transfer the solar energy that is received into power and charges the battery. The battery supplies power when needed. In comparing the two systems, the Stand-alone system is less costly and has higher energy conversion.
In the past one hundred years, lighting has developed through three stages: incandescent, fluorescent, and High-Intensity Discharge (HID) lighting. Incandescent lighting is first generation, fluorescent lighting is second generation, and high-intensity discharge lighting is the third generation. Now with the great development prospect of the LED lighting industry, LED is considered the fourth generation of lighting. LED is a semiconductor light source which has the advantages of longevity, energy efficiency, high luminosity, fast response, low voltage, and solid-state, as well as the convertibility of alternating current to direct current. Also, the LED start and operating voltages are consistent so does not require a lighting ballast. While saving costs and energy, the LED has greatly shortened the response time of electrical continuity.
Solar energy generation operates on low voltage direct current lighting. An inverter is required to convert direct current into alternating current electrical load. A large amount of energy is lost in the conversion. In comparing the light sources in the lighting market, low voltage current that LEDs use is obviously most suitable to power a solar energy system.
As we all know, LED produces no flicker, has fast response time, and is most suitable for lighting control systems. Solar energy systems have certain requirements for the control of lights and other loads. Especially when it comes to saving energy, the load controller controls the solar load by switching the connection on and off. This makes LED the most suitable light source for solar energy systems.
In summary, since LED uses direct current and has low operating voltage, it is compatible with the solar battery which transfers the solar energy into direct current. The solar battery parts through a series and parallel connection can receive suitable LED voltage. At the same time, LEDs can also be connected into series and parallel to match the solar battery voltage. Furthermore, LED lighting does not flicker, has fast response time, and is currently the most suitable light source in the lighting and solar control system markets. The combination of the two allows for high energy utilization, increased safety and reliability, and is energy conserving and environmental friendly.
In October at the Melbourne Exhibition & Convention centre was the All Energy conference, for the suppliers & distributors of solar, wind and other renewable energies. There were a lot of delegates in attendance for the workshops and trade floor; and ReneSola was involved in a few of the workshops.
Some of the sessions chaired by Derek Marsden (GM ReneSola Australia), were Project Development with a key focus on capital ventures into green technology and regional trends with installations. Also there was international knowledge sharing between representatives of the solar installing market from the US, Canada and Australia. For more details email firstname.lastname@example.org

ReneSola has launched a skills competition to further strengthen and improve ReneSola employee skills and work quality at its factories. The exercise covers the inspection of solar cells, solar cell diffusion inserts, cleaning techniques, and product packaging. The goal of this exercise is to identify training needs, operational knowledge, and outstanding staff to build on company development, outstanding quality and performance, sophisticated technology, and a superb product line staff. During the month of July, employees of various departments in quality testing got together to compete in an interesting competition.
In the solar cell inspection test, 12 employees had to analyze and select the solar cell sheets with damaged exteriors and input the correct information in the database. The highest scorer won the test. The criteria were based on the understanding of inspection standards and trivial questions. The intense competition and skilled work of the contestants were admirable.
The processing of diffusion inserts required employees to be fast and have good eye and hand coordination. The criteria of the solar cell diffusion inserts test were: wearing of gloves standards, vacuum tube movements, placement direction of inserts, and handling of inserts and quartz. Points were marked off for broken inserts and suction devices not secured properly. Three female contestants with the highest scores were the winners of this test.
The cleaning techniques test required two people in a team to work together. Contestants were scored in the areas of equipment operations, quality, and speed. The final test was the packaging of the solar modules which is also the last step in the quality inspection. The test required the contestants within 20 minutes to select the solar panels that do not meet quality standards out of ten different types of panels. The contestants must identify the different power levels and affix the aluminum plate on the panel after inspection. Judges gave points based on time used and level of completion. Those who finished the task in less time were given higher scores.
“We have been watching this company for some time now. They have the most efficient and consistent panels out on the market and are a key research and development supplier for solar companies. They provide a high-quality product and we’re pleased to work with them,” remarks Warren Hall, Owner of Blue Tongue Solar.
