Why don't Cantonese use solar energy?

Reason one: There are misunderstandings among citizens.

For the general public, the most common solar energy product is the water heater. "Laoguang" has the habit of taking a bath every day, and the amount of hot water is large, so it should welcome energy-saving and environmentally friendly solar water heaters. But this is not the case.

In Guangdong, where the sunshine time exceeds 2000 hours every year, the penetration rate of solar water heaters is only 2%. According to Chen Yucun, vice chairman of Guangdong Solar Energy Association, the current installations are mainly collective users such as schools, hospitals and factories, and there are few individual families.

"The main thing is understanding." Chen Yucun said, for example, I'm worried that it won't be used on cloudy days and that the first investment is too big. He said it was a complete misunderstanding. Guangdong has a long sunshine time and a large amount of radiation, and it is only cloudy for 60 to 80 days every year; Even on cloudy days, solar water heaters can absorb heat. If it is cloudy for a long time, it can also be used with electricity and gas.

In addition, it is economical to use solar water heaters. Take a family of three as an example, the initial installation cost is two or three thousand yuan, but after installation, at least eight or nine kwh of electricity is saved every day, and the electricity fee is saved by more than one year 1000 yuan, and the cost can be recovered in two or three years.

Reason 2: The management department is not active.

In addition to energy saving, the use of solar energy will also bring huge social benefits such as environmental protection to the local area. According to statistics, Kunming, the city with the most mature solar energy utilization in China, can save 80,000 tons of standard coal, reduce carbon dioxide1.1.01.000 tons and 445 tons of sulfur dioxide every year, making it a veritable "sun city".

With environmental protection and energy saving, the utilization rate of solar water heaters in China has been very high, reaching more than 10%, much higher than that in Guangdong. In areas with good solar energy conditions such as Tibet and Yunnan, the penetration rate has reached 30%; Even in Jiangsu, Zhejiang and other provinces where solar energy conditions are far worse than those in Guangdong, the utilization rate is nearly 20%.

According to industry insiders, this is not only the understanding of users, but also the initiative of relevant local management departments. For example, in Kunming, the relevant departments have clear instructions on the installation of solar water heaters.

And in Guangdong? According to Chen Meicun, there is no clear plan for solar water heaters in Guangdong, let alone guidance and encouragement. The reporter once asked the relevant person in charge of the planning department of Guangzhou for verification, and the answer was: At present, there is no such plan, and the public had better consult or report to the nearest planning branch before installation. However, what the reporter learned is that a small number of retail investors currently installed are basically "stolen" without reporting.

Reason 3: Residential property management is not allowed.

Solar water heaters are energy-saving and environmentally friendly, but some people living in residential areas have encountered another problem when they want to install them-the residential property management office does not allow them, on the grounds that they "affect the appearance". Miss Zeng, who lives in a large real estate in Panyu, told this newspaper that she was going to install solar hot water pipes on her rooftop, but the property management office blocked her and threatened to cut off water and electricity.

In fact, it is not uncommon for this receiver to interfere without solar energy. In this regard, the person in charge of a large solar water heater factory in Guangdong also said that the community can be installed uniformly, just like outdoor air conditioning, "it is also very beautiful." However, this person also suggested that it is best to install solar water heaters in new houses, so as to unify the style and provide central heating. All families only need to install a hot water faucet, which is not only beautiful in appearance, but also cost-effective. He said: "This is also the supporting style of new houses in some cities in the mainland."
