The solar carport first appears in Center park， which is a combination of power generation， sunshade and rain protection.
The company’s manager: you can save electricity charges of more than 200 yuan every day. We think that the solar power’s application to this field has a promising future.
Citizens are very familiar with carports that are used for car parking. Their materials are simply plastics, steel, tensile membranes, etc. But recently, there appears a special carport in Ningbo Beier Energy and Technology Co., Ltd. in Cidong industrial park. The rooftop of the carport is made of mono-crystalline silicon. It can not only be used to generate power, but also prevent against the rain and the sun (as shown in the figures).
A high-end, magnificent and upscale carport appears in the factory.
The reporter arrived in Ningbo Beier Energy and Technology Co., Ltd. on the afternoon of the 9th day this month. There is no significant difference between this carport and common carports if you see from a distance. It’s hard to tell that this carport is made of the solar cell panel. But you will find out that the rooftop of the carport consists of 188 sheets of monocrystalline silicon after checking it carefully at a short distance. The lines can be seen below the rooftop of the carport. It is reported that this company has two solar carports standing in a line. They cover an area of 250 square meters and can accommodate 20 cars.
There is a luxurious showroom with four transparent sides on the green space beside the solar carport and it is equipped with a power generation monitoring system. The reporter can see when the everyday peak value of the power generation is, the real-time voltage, the electric current, the output power, the illuminance， the wind speed, the temperature, the wind direction… clearly from a big screen. The company’s chairman Mr. Hua said this showroom can monitor all the real-time data when the solar carports generate electricity.
Mr Hua revealed that what the solar carport uses is grid -connected power generation. It can only be connected to the internal power grid of the factory rather than the national grid directly because what the solar carport provides is direct current. However， the direct current can invert to the alternating current of 220V-380V automatically through the special equipment. It can even invert to the ultrahigh voltage. When the equipment which uses solar power supply runs into the insufficient power， it can switch to the national grid automatically so black-out will not happen.
Save electricity charges of more than 200 yuan every day
When the reported mentioned how they had the thought of combining the solar energy with the carport, Mr. Hua said he had the thought one year ago. At that time we hadn’t carports for car parking. Considering that our carport is in solar industry, we just had a though of applying the solar cell panel to the carport. We can not only save electricity charges, but also regard the application of the solar power as a new attempt. We acted without delay. After a year’s preparation and organization, it was built successfully in June this year when going through the installation and debugging.
During the interview, the reporter knew that the whole solar carport’s maximum peak value of the power generation can reach up to 35 KW each hour. It can generate power of 200-300 KW.h especially in sunny days. Mr. Hua said if they just use common materials, the cost of the carport is just 70 thousand and now 350 thousand yuan is involved. ‘If the electricity charge is 8 jiao/ KW.h, you can save at least 150 yuan each day. If relevant policy subsidies are included， you can even save more than 200 yuan each day. Considering the cloudy and rainy weather, however， we expect to recover the cost in 7 years.’
Mr. Hua said the combination of carports and solar power generation can not only protect against the sun and rain, but also generate power. That is like killing bird with one stone. The maintenance cost of this kind of carport is very low. You just need to wash the panel every 2 or 3 months but its lifespan can reach up to 25 years. We will consider installing charging facilities like charging piles below the carport in the future, which can charge facilities that need to use electricity directly. It is reported that the company has planned to install the solar cell panel of 3KW on the rooftop of the factory in the second half of next year and take advantage of the solar power to supply electricity in every aspect.
It is very easy for solar carports to generate power.
It is understood that solar energy resources have many advantages such as green environmental protection, no pollution, direct exploitation and utilization, etc. They have been exploited and applied to more and more fields. Using solar power to generate electricity has been very common in some developed countries like Europe and America, schools, commercial centers, technology parks and even individual families. Although the solar cell panel has been widely applied to the fields such as the industry, life, traffic, etc. , it is still a long-term and arduous work for it to get into families in China.
Mr. Hua said common people probably think the solar carport is very novel and needs high technology. But the truth is completely different. We can even say that it is very simple because this kind of technology has been very ripe. We just change the position of the solar cell panel and apply it to the carport. In fact, the principle is the same-the solar power absorbs the sunshine radiant energy and transforms into the electric energy. Many people haven’t even seen that the solar cell panel can be installed on the carport and they don’t know about that as well so people feel it is high-end, magnificent and upscale.
Mr. Hua said it is very rare to take advantage of solar carports to generate electricity in China. This kind of power generation can make good use of cities’ little space to produce green power so we think highly of the prospect of solar power’s application to carports. This attempt can be regarded as the touchstone for our company’s future development fields. If it works well, maybe we will make corresponding promotion and release it onto the market in the future. Maybe it will become another business item of our company.
