Solar Lighting: Broader market development

One of the highlights of the 2012 Guangya Exhibition was the addition of solar panels. This move conforms to the country's new energy strategy and is of great significance to the progress of China's new energy technology and the promotion of new lighting development.

According to the data, solar lighting is essentially a photoelectric conversion system. The field of expertise is called "silicon wafer ground photovoltaic modules." Its working principle is that the silicon wafer receives the sun light and then converts it into electricity. It is then stored in a battery and then controlled by a light switch. It automatically lights up when it is dark, and goes off automatically when it is on.

Because silicon wafers are expensive, the initial solar energy is only used in the aerospace industry. After a slight breakthrough in technology, the United States, Japan, Germany and other developed countries took the lead in trying to use them in high-tech fields. With the development and progress of solar photovoltaic technology, it is first applied to lighting fixtures in civilian applications. In recent years, due to the dual advantages of environmental protection and energy saving, solar lighting products have gradually formed scales such as solar garden lights, solar lawn lamps, and solar decorative lights.

At present, domestic solar energy technology is still in its infancy, far lower than foreign advanced level. In the face of the dual pressures of energy and the environment and the huge market to be developed, foreign companies have shown great interest and enthusiasm in exploring the Chinese solar energy market.

In order to make up for this deficiency, this year's Guangzhou International Lighting Fair has introduced nearly 100 European and American solar energy companies, bringing the world's most advanced technologies and achievements.

A person in charge of the exhibition said that the cost of solar lights is higher than that of ordinary luminaires; if the construction costs of the invested projects are included in the whole project, the two luminaires will be priced at the same initial investment. The larger the project, the higher the construction cost of ordinary lighting, and its initial investment is greater than solar lighting. However, the longer you use it, the more you can demonstrate the benefits of solar lighting. If the manpower and material resources are included, the auxiliary lighting costs and maintenance costs of ordinary lighting will be higher than the budget. In the subsequent use of the cost (electricity, maintenance costs, etc.), the advantages of solar lighting is more obvious.

In fact, after several years of promotion, the advantages of solar energy have now been accepted by more and more people. As one of the series of solar energy applications, solar lighting has always been the focus of research and attention of all parties. The company predicts that solar lighting will have an opportunity to become popular in the country in the next five years and become the future lighting industry development trend.

The company also stated that it hopes the government can give policy support to the entire solar lighting industry. In foreign countries, the world's solar energy industry is far ahead of Germany. In the "Renewable Energy Law" revised in 2003, it was emphasized that power companies purchase renewable energy at a guaranteed price, enabling Germany to obtain subsidies of 3.4 billion euros for solar energy and other renewable energy industries in 2005. .

According to reports, Germany’s “One Million Roof Project” has enabled many families to use solar energy not only to solve their own energy use, but these families have also become small “private power stations” that continue to deliver electricity to grid companies and generate a considerable amount of revenue. .
