Why solar lighting systems are difficult to promote

"Going out on the road, the future can carry solar modules to charge mobile phones," "Natural showers on the beach can be powered by solar energy..." This year's high-tech fair has attracted many visitors. It is understood that, at present, the application of solar energy technology and people's lives are closer, but solar energy should really enter every family's homes, and become an indispensable alternative energy for everyday life such as living lighting, and there is still some way to go.

The story sells solar energy products for the first time.

There are more and more solar energy companies exhibiting at the High-Tech Fair, and their products are changing with each passing day. However, the current technology and market prices make it necessary for these products to “fly into the homes of ordinary people”. One entrepreneur who was fighting in Germany stated that enterprises must successfully overcome the technical difficulties and overcome market difficulties in order to successfully promote solar energy products.

Developing completely innovative solar energy products German-Chinese German Liu Xu is presenting his products for the first time at the Shenzhen Hi-tech Fair. "I started researching solar applications in 1998. I started working at a large German research institute and later went to a company as a development engineer."

The stable and comfortable living environment did not eliminate Liu Xu's entrepreneurial dreams. Liu Xu, who wanted to find a place in the solar energy field, founded Ake Lima Technology Co., Ltd. in Germany. He also had a close relationship with Shenzhen. At the beginning of the venture, there was a shortage of funds and talents. An engineer from Shenzhen joined Liu Xu's team. “At the time, Shenzhen SEG retired senior workers Hou De helped to do product quality management, which helped the start-up companies and the team made concerted efforts to create completely innovative products in the market.”

In the words of Liu Xu himself, the product he developed is “a solar submersible pump that can be driven by at least two A4 paper-sized solar panels and can provide home drinking water, green drip irrigation, and beach showers.” The reporter saw at the scene that the solar submersible pump is very compact and simple in appearance, but its use is very extensive. “A lot of plant greening in the city needs irrigation, and the use of this small-flow-rate, environmentally-friendly water pump for automatic drip irrigation is very environmentally friendly,” said Liu Xu.

“Being too advanced” was said by customers that they couldn’t understand Liu Xu’s entrepreneurial momentum. It was soon discovered that this small-scale solar application was difficult to open the market, but he “couldn't leave it down”, and he just supported the company. Go on. Liu Xu said that the development of solar energy products has taken a long time to develop. There is nothing wrong with the company's products. The only drawback is that it is too advanced. The first reaction that many people see when it comes to products is: Why do you use this stuff?

“In some remote market areas, customers have difficulty understanding and using this box, so the biggest difficulty is to promote popularization. Once people understand the changes that these solar energy products bring to life, they will It is easier to accept the use.” Liu Xu said that the market situation was slowly opened, and some customers would order online and on the phone. For example, customers in Norway call to order, saying solar water pumps can come in handy when they are on holiday in a forest chalet.

Someone persuaded him that since there is a new energy technology selling point, why not "play the concept"? However, Liu Xu adheres to a step by step operation. “The more innovative the product is, the more faithful it is” and cannot be sold for the sake of selling the product. At present, Liu Xu's products are mainly sold to markets such as Germany, France and Switzerland and are welcomed by local residents.

Reducing costs for each family to accept sales for the domestic market, Liu Xu said he was very confident. “In Germany, the proportion of renewable energy applications is already high. In the future, Chinese households will also increasingly use solar energy. Especially in remote areas, it is entirely possible to use a similar product to make the living environment more comfortable.” But Liu Xu Frankly, it will take some time for the solar energy to go into each family. In addition, the concept of people living in each region is different, and the degree of acceptance of solar products is different. However, in the future, solar energy products will become more popular as technology advances and costs decrease.

Zhou Minyi, chairman of Shenzhen Allianz Allianz, also expressed the same opinion. “There is still a long way to go before the use of solar energy in the lives of ordinary residents. Especially for solar roof lighting systems, whether the price can be accepted by the market is a big problem. Due to the limitation of living space, urban life needs to be applied. Solar energy needs another way, such as solar lighting for underground garages."

Need to strengthen popular science, overcome technological difficulties, reduce costs How close is solar energy to ordinary citizens? What is the development of the solar energy industry and its application in the daily life of citizens? Why is it difficult to popularize solar roof lighting systems for urban residents? The reporter learned from experts in the industry that the application space and industrial development space of solar energy are enormous and will be the future development trend. However, large-scale applications still need to strengthen popular science, overcome technical difficulties, and support related policies.

Solar energy science needs to be further promoted. "Solar energy is getting closer to the ordinary people's life, but most people don't have intuitive feelings about it." Zhang Jian, secretary general of the Shenzhen Solar Energy Society, told reporters that solar street lights on the Shenzhen Binhai Avenue are located in the "Park." The 1 MW grid-connected solar photovoltaic power station in Shenzhen and the underground garage for solar lighting newly completed in the Civic Center are closely related to solar energy.

Solar energy can be linked with our food, clothing, housing and transportation, including “organic vegetables” that residents can buy in supermarkets. They may use solar-powered “pesticidal lamps” to prevent insects, and solar energy “shaking head dolls” that are easily available to the public. Solar product applications. Zhang Xin believes that these new and practical products have brought new energy sources closer to the ordinary people and are a good breakthrough point. They conform to a customer-oriented market and lay a good foundation for solar energy companies to start the domestic market and further expand the international market. Foundation. In daily life, ordinary people's application of solar energy is still limited to "solar water heaters", and solar energy lighting and photovoltaic building integration are still not well understood. This shows that solar energy science needs to be further promoted.

There are technical difficulties that need to overcome the difficulty of letting the sun directly illuminate our room. The reporter learned from the interview that, first of all, most of the buildings did not take into account the needs of solar panel installation. Solar panels must be integrated with the building in order to promote solar roof lighting.

Zhou Min, chairman of Shenzhen Allianz Allian, told a reporter that under the current conditions of solar panel conversion efficiency, building a solar roof power station is inefficient and requires a lot of building roof resources, while the city’s building roof is very expensive and Scarce, it is difficult to provide the space needed for the construction of solar panels for power stations; at the same time, the economic benefits are also low. The average investment recovery period of rooftop power stations needs to be more than 40 years, and the average lifetime of solar photovoltaics is only 20 years. Investment and return Can't match.

Zhou Minyi, for example, said that for ordinary residents, most of them are living in high-rise buildings. Due to the restrictions of living space, it is not easy to place solar panels in suitable places. When solar water heaters are installed on the roof, they lose solar panels. The space and opportunities; Secondly, the cost of 10 square meters of panels is at least 50,000 yuan, and the amount of electricity generated is not enough to meet the needs of the entire family. In the future, “photovoltaic architecture” combining photovoltaic power generation and buildings is a general trend. However, under current conditions, urban residents use solar energy lighting, and most of them are first promoted in public space.

It is hoped that the cost will be further reduced. "Solar solar thermal utilization is a very strong policy industry." Liu Xu said that many countries have introduced relevant subsidy policies and incentive mechanisms for the solar energy industry. The reporter was informed that from March 2009, the Chinese government decided to allocate about 10 billion yuan annually from the government to provide subsidies for the construction of solar roofs and photovoltaic buildings to promote the formation of a domestic solar power market.

"But we must see that these preferential policies are only an encouraging gesture." Zhou Minyi said that the use of advanced technology and advanced products in commercial use depends on the degree of price acceptance for the market rather than government subsidies. How many. “At present, one of the major factors restricting solar energy for large-scale civil use is cost and reducing costs is the top priority. Significantly increasing the efficiency and efficiency of photovoltaic power generation is an important way to reduce costs.” Zhou Minyi said, “Once a price bottleneck is broken, The application of solar energy cannot be imagined."

Liu Xu also believes that solar companies cannot rely on the government's financial support alone. They must explore new business models, meet the needs of users without increasing the burden on users, and use their own innovative technologies and products to guide market demand.
