In 2019, the new installed capacity of solar photovoltaic power generation in China was 53.06GW, an increase of 18.52GW year-on-year, with a growth rate of up to 53.62%, setting a new historical high again.
can be said to be infinity of scenery, but it is just a temporary scenery!
Solar energy, as a clean energy that has been developed and currently quite effective, has always been highly anticipated, and the photovoltaic industry looks to have broad prospects.
But with the continuous development of technology, solar energy has gradually disappeared in our "eyes", and can also be said to be "no one cares about it".
What is the situation?
is the country banning solar energy?
does not, and the country does not disable. What exactly is the reason for
?
Why is solar energy abandoned?
has three reasons.
First, solar energy has certain limitations;
First, how does solar energy rely on to generate electricity?
The energy of solar energy comes from the energy of celestial bodies outside the earth (mainly solar energy). It is the huge energy released by the fusion of the hydrogen nucleus in the sun at ultra-high temperatures. Most of the energy required by humans comes from the sun directly or indirectly.
To put it bluntly, it relies on the sun to generate electricity, and it needs the sun to replenish energy.
But have you ever thought about the areas and provinces that don’t have much sun all year round?
For example: Guizhou;
It is one of the most cloudy provinces in my country. It is cloudy almost 9 months a year, and "the sky is not sunny for three days" is the characteristic of Guizhou's climate.
For example: Chengdu, Sichuan;
According to statistics from the Weather Network, from January 1, 2011 to November 1, 2021, Chengdu had a total of 1,377 days of cloudy, 1,280 days of rain, and 968 days of cloudy. In comparison, there were only 20 sunny days, with an average of only 20 real sunny days a year.
So have solar energy installed here? Have you ever respected the "sun"? There is no sun in
. How can I replenish the energy of the northwest wind when installing here?
is really true, new energy can be installed.
Second, there are new substitutes (new energy) appear;
Yes, that's right.
Since there are not many suns in these places, can we consider wind energy?
really doesn't work, hydropower generation is also OK.
Let’s take Sichuan as an example and say how Sichuan relies on generating electricity. must be inseparable from water at this time.
Let’s look at a set of data first:
Sichuan’s total power generation in 2021 is 430 billion kWh, but hydropower generation reaches 370 billion kWh. The data set of
shows that Sichuan mainly relies on hydropower.
As the saying goes, The world's hydropower is looking at China, China's hydropower is looking at the southwest, and the focus of the southwest is in Sichuan.
Sichuan has the title of "Province of Thousand Rivers".
More than 1,400 rivers of all sizes have created the trump card of major power generation provinces, making Sichuan's installed capacity and power generation both ranked first in the country.
According to reports, by the end of 2022, the installed capacity of hydropower in Sichuan Province is expected to exceed 100 million kilowatts.
Third, there are problems within the industry;
"Photovoltage fraud" I believe everyone knows!
In order to make more money, some people have started to show bad merchants, and even some fraudsters.
is especially seen in rural areas. lied that the photovoltaic is installed on the roof, which not only uses electricity for free, but also makes money.
has such a big "good thing", it is impossible not to take advantage of it.
So many fraud gangs used photovoltaic power generation to deceive rural villagers, fooled them into installing solar panels in various ways, and gave benefits.
But after installation, what they got was inferior products, and the villagers didn't have time to regret it.
. They used the villagers' ID cards to apply for loans, had long run away with the money, leaving the villagers to repay the loan alone.
Let’s take a look at a case.
On March 30, 2022, Suzhou Long Mouxiu invested in virtual photovoltaic products on a website through a friend's introduction. The bank card provided by him to the customer service was transferred a total of 190,000 yuan. Later, he found that he could not withdraw cash and the website could not be opened, and found that he was cheated.
So no matter who you are facing, we should be vigilant.
If you encounter investment and financial management needs, must invest through a formal platform, and do not trust telemarketing and online promotion, etc. Is it worth it to install solar energy in
?
Of course, everyone has different opinions, and in my opinion it is worth it.
is relatively cost-effective for a family and can reduce electricity bills a lot. However, the installation cost is relatively high, so in this case, you have to consider your own financial ability.
Because solar water heater system is fully automatic and static, without special care, it is safe and reliable, environmentally friendly and energy-saving and other characteristics.
Of course, the same thing is still the case. Everything depends on your needs.
Don’t blindly follow the crowd, , for example, everyone buys it, and then follow it to buy it yourself.
We should consider ourselves, and we should also consider whether the family needs it. If you need it, you can buy it, and if you don’t need it, you don’t need to buy it.
