On December 28, 2017, the world's first 1.1-kilometer photovoltaic highway was unveiled in Jinan, which triggered reports from the national and world media. However, media reports have recently damaged the photovoltaic modules of this highway for six months. , I have to close the maintenance frequently. At present, the fast lane part of this photovoltaic road has been patched a lot, it seems mottled.
Photovoltaic road is a scientific and technological concept. A road can be both open and power-generating. It is said that in the future, electric vehicles running on it can be directly charged. So this photovoltaic road has attracted countless eyes since its inception. At that time, there were even people. Interpretation said that the photovoltaic road is the life of the gas station. Because it is the 'first section of the world', this photovoltaic road was once regarded as the representative of China's scientific and technological progress.
But the ideal is full, the reality is the bone. Only half a year, it is full of patches, but also often closed maintenance, no doubt a good sign.
We even have reason to worry that this PV high-speed project is not another 'Ba-Tie' image project.
'Batie' is the 'stereo bus', between the tram and the bus. The upper level can carry passengers. The lower level has windows and lights to pass the vehicle. When the concept came out a few years ago, it was also interpreted by many people as ' The invention of the stunning world, 'Made in China shocked the world'. But in the end, this brainstorming project became a financing scam, and the investor’s boss was arrested for illegal fundraising, leaving a chicken feather.
After the "Batie" myth was shattered, people summed up the lesson. One of them was: Without considering the technical feasibility, they blindly beat the 'patriotic card'.
So is PV high-speed project a project of the same nature? I dare not rush to conclusions, lest people be labeled as 'blocking domestic innovation'. But there are some questions that have to be made.
As early as the PV Expressway was unveiled in Jinan, some netizens raised questions, such as conversion rate, cost, and durability. After half a year of practice testing, these problems were more prominent.
There have been reports in the media that the photovoltaic section is expected to generate about 1 million kilowatt-hours per year, and its economic benefits are very impressive. 'The cost of the photovoltaic highway is 3,000 yuan per square meter, which is much higher. According to reports, the total net area of this photovoltaic pavement is 5,875 square meters, which is roughly calculated, and the total cost is about 17.6 million.
The annual power generation is 1 million kWh, which is calculated according to the civil power of 0.5 yuan per kWh. The annual income is 500,000. The design life is 15 years, and the total income is about 7.5 million, which is almost the fraction of the total cost. This kind of economic benefit can't be called 'very Considerable.
From the practical results, the annual power generation of 1 million degrees is still an optimistic estimate. On April 4 this year, some media reported that the cumulative photovoltaic power generation in this section was nearly 100 days, and the cumulative power generation was 87,920 kWh. That is, less than one hundred days of power generation. 8.8 million degrees. Although there are seasonal factors, but damage, maintenance will also bring loss of power generation efficiency.
This project was launched from the very beginning without commercial viability. The investor is a state-owned enterprise, and the financial situation is crude. It does not put tens of millions of costs in the eyes. A person in charge of the project has said: 'This It should be said that it is a long-term strategic decision. It is still a venture capital project. ' But the actual exposure problem is more significant than the laboratory data.
It is worth noting that the person in charge also said: 'The birth of every new thing is not smooth sailing. From the beginning everyone is squatting, to the gradual solution of the problem, and then forming a large-scale industry, like Tesla. The same growth. '
There is no problem with this passage alone, but venture capital is not without paying attention to earnings, but more emphasis on long-term gains. Tesla is not a public welfare enterprise. Musk is squandering for capacity to prove that Tesla has earned Money ability. So is this 1.1-kilometer 'the world's first photovoltaic highway' with long-term business prospects? Or, the purpose of its existence is to spend money to make a big news?
If you just take the road to do the experiment, can you do it short? Even if you want to test on the actual road, there is no need to test it at high speed. Frequently closed construction will affect the road traffic, road damage is also It may cause a safety hazard.
We must praise for independent innovation, but we must also be wary of taking the initiative to create gimmicks. A technology can not be allowed to discuss because of wearing a hat for the country, otherwise it is a great injustice for those who are down-to-earth.
Whether photovoltaic high-speed is a gimmick or a true innovation, please give evidence to speak for yourself.
