Home photovoltaic parity Internet access: Can you stop messing around?

Recently, with the official launch of Yongzhen Technology's industrial and commercial roof subsidy-free project, cheap Internet access has once again become a hot word in the industry. Some enterprises took the opportunity to announce that they would build a number of distributed photovoltaic projects for residents without subsidies to reduce the subsidy burden.

It sounds really tall, but is this goal really that easy to achieve?

Power generation and income forecast should be reliable.

Let's look at this screenshot first:

Sure enough, the technical level limited my imagination. It turns out that photovoltaic power plants can be installed not only on the roof of buildings, but also in the sun, working 24 hours a day, thus achieving ultra-high power generation and meeting the output requirements.

The following one is more interesting:

It must be pointed out that "the first year rate of return" is a rogue concept. Many cities have local photovoltaic subsidies. Take Hangzhou mentioned above as an example. According to the Implementation Opinions of Hangzhou Municipal People's Government on Further Accelerating the Popularization and Application of Solar Photovoltaic to Promote the Innovation and Development of Photovoltaic Industry (Hangzhou [2016] No.79), the distributed photovoltaic power generation project connected to the grid before 20 18 12 3 1 will be given 0.655. The subsidy in Zhejiang Province is 0. 1 yuan/kwh, and the first-year rate of return can reach14.54%. If the project happens to be in Fuyang District or Xiaoshan District, you can still get district-level subsidies, and it is not a lie to reach 17%.

However, it is easy for consumers to misunderstand that after installing photovoltaic system, the annual rate of return can reach 17%. In fact, the influence of local subsidy years on the rate of return can not be ignored. Furthermore, even if this factor is not considered, the annual output will gradually decline due to the attenuation of parts efficiency, and it is too unreliable to calculate the income only by the power generation in the first year.

In the process of photovoltaic system promotion, the above false propaganda and word games are common, and people who don't know enough about photovoltaic industry suffer greatly. Previously, there was an example in Zhejiang, where the owner was dissatisfied with the 3KW system with 65438+ 10 generating 282 degrees a month, which was exposed to the media. However, in the view of Sobi photovoltaic network, there are more rainy days in 65438+ 10, which will affect power generation, so it is reasonable to use only 94 hours. The reason why customers are dissatisfied is probably because the marketing staff talk nonsense in the publicity stage, which leads to the high expectations of customers for power generation.

Household photovoltaics need subsidies and stable support.

Not long ago, the Human Resources and Social Security Bureau of Yichun City, Jiangxi Province received a proposal to encourage citizens to take the initiative to apply for giving up receiving pensions, but the reply was "the proposal is not feasible" and was resisted by the people of the whole country.

I always thought this joke was far away from us until I saw this sentence on a photovoltaic media:

Should the subsidy be withdrawn after the investment cost of the power station is recovered? This idea completely ignores the characteristics of "low electricity price and low self-use rate" of household photovoltaic. If it is only to save electricity and have no extra income, it is impossible for ordinary people to spend tens of thousands of yuan on photovoltaic investment at one time.

No wonder the members of the group refuted after reading the article.

A, it's too idealistic. It is precisely because of these unrealistic ideas that the 53 1 policy is across the board.

B, we can't just consider the cost of self-investment, and we can't develop without channel profit.

C. I hope to stick to my promise, and the subsidies mentioned in the previous paragraph of the New Deal can be given in time and can be honored for 20 years.

Dr. Qu Xiaohua, Chairman of Artes, believes that it is a commitment to continuously subsidize photovoltaic projects for 20 years. No matter how the policy is adjusted in the future, the stock projects cannot be affected. "Did you violate the subsidy for the installed photovoltaic system? Yes, Greece and Bulgaria. Is it necessary for China to keep up with these? The New Deal does not go back to the past. No matter what the reason, unless the financial collapse, red-headed documents can not be easily changed. " This attitude has been widely supported by members of the group.

What's the difference between household photovoltaic and industry and commerce?

I often see the saying that "the electricity side is connected to the Internet at a low price", but I said in my previous article that due to the fundamental difference in electricity prices, the two must be discussed separately and must not be confused.

At present, the LCOE of photovoltaic power generation has been lower than the average industrial and commercial electricity price, far lower than the peak hour electricity price. In other words, we have successfully achieved online parity in this field, and subsidies are icing on the cake. For household photovoltaics, the residential electricity price is usually only 0.4-0.55 yuan/kWh, and subsidies can reach the average level of industry and commerce, which can be described as "giving charcoal in the snow".

From the perspective of self-use ratio, few household photovoltaics exceed 20% in this indicator. According to the data of Energy Bureau, in 20 17 years, the domestic electricity consumption of urban and rural residents in China was 869.5 billion kWh, and the average electricity consumption of a family of three did not exceed 1900 kWh, which was equivalent to 15.8% of the annual power generation of 10KW photovoltaic system (at 1200). If someone tells you that the proportion of household items can reach 80% or even 100%, then he must be a local tyrant. Please hold his thigh tightly and let me know.

The purpose of writing this article is not to cry for poverty, nor to ask the competent authorities for money. Facts have proved that after years of confrontation, the three ministries and commissions have already cultivated a heart of stone, and the saying that "crying children have milk to eat" is not established. It is also hoped that manufacturers and distributors will take into account the interests and development prospects of the industry while destocking, and do not make false propaganda to boost short-term shipments and stock prices, mislead competent authorities and consumers, and damage the reputation of the photovoltaic industry.

At least we must ensure that after the newly allocated indicators are issued in 20 19, we still have food to eat, and the photovoltaic industry will not be shouted down by everyone.
