How about Qilu Star Solar

Despise those black-hearted advertisements that mislead consumption!

Solar power generation, power generation per square meter is about 120w, the cost per square meter is about 1500 yuan, and the larger the area, the lower.

In 2013, the photovoltaic industry was investigated by the anti-monopoly of Europe and the United States, and overcapacity led to the collapse of a large number of photovoltaic industries in Zhejiang. This can be checked online at any time.

It is recommended to buy solar water heaters** each priced at 150-180 yuan, including other costs such as materials and materials.

In the case of solar panel power generation, the proposed bidding for the scale of the group is mainly due to the fact that the power transformation and storage power equipment is very expensive, and the conversion rate is up to 17%-20%, which is very inefficient, and it is not as good as plant photosynthesis.

At present, the national clean energy and photovoltaic power generation support policy is that more than 10kw can be connected to the grid for free, but the electricity price is very low and the procedures are cumbersome.

When choosing a solar water heater, it is first recommended to consider the local climate, installation conditions, economy** and durability.

1. Local climate: The solar tube of the solar water heater will not freeze and crack in winter, but many people will find that in addition to the solar tube, the others are basically frozen and broken. It is indeed a waste to take half a bucket of cold water before taking a bath;

2. Installation conditions: the water pressure is not good, the floor is high, and it is recommended to wash and sleep when you are ready to install a mixture of solar energy and electric heat. The associated auxiliary equipment, including booster pumps, controllers, will force you to spend a lot of innocent silver, and you will always feel like you are riding a donkey.

3. Economy: In terms of use, solar energy is more than 3,000 yuan, electric water heater is about 1,500 yuan, gas hot water is about 2,000 yuan, although solar energy does not use electricity, but experienced friends know that solar energy can not be used without electricity, so we don't talk about saving electricity. In terms of utilization cost, natural gas pipeline gas is the most economical, followed by electricity bills, comprehensive cost, buy solar energy to spend an extra 1500 yuan electricity equivalent to 3000 kilowatt-hours of electricity, enough for you to use for a few years.

4. Durability: The safe use period of electrical products is 6 years, solar energy will leak in the later stage of use, and the conversion rate will gradually decrease, knowing that you intend to give up.

Solar energy as a clean energy is quite good in the long run, but due to the limitations of artificial technology, the conversion rate is not as high as when we directly plant trees and boil wood to boil water, it is recommended to buy carefully.

After all, the ladder electricity price and new energy promotion policy are voted for in the Great Hall of the People, we don't know that the representative is us, and there is only how much it rises in each hearing, and it never rises or falls.

The above is purely a fool's dream, and any similarities are purely coincidental.

I despise advertising, especially the black-hearted advertising of some companies!

Know that the team is after-sales --- God's customer service.

Qilu Star solar energy quality is very poor, and the service is very poor,

There are counterfeit brands. For example, the Star of Brother Mu in the Four Seasons. Pastoral Song of the Four Seasons. Pay attention to discernment. Hope it helps.

Have a great day.

I have been at home for a year, and there are always problems, poor after-sales, poor quality, and even worse accessories!

My home Qilu Star solar energy, the quality is too poor, the after-sales service is poor, and the service is even worse! If it's broken, no one cares about it!

Qilu Star solar water heater can not be bought, who buys who is fooled, the service is directly unreliable, I used Huangming solar energy for 17 years, Qilu Star only used two years to rot!

Find me, you won't be disappointed.

The amount of water stored by nature is also known as groundwater, but it is different from the amount of dynamic water in groundwater that participates in the modern water cycle and can be renewed. It was formed by nature on a time scale of millions of years. For example, beneath the Beijing Plain is a huge "underground reservoir" filled with pore water.

It formed naturally over a period of about 3 million years. If the aforementioned "total water resources" are compared to the sustainable supply of solar energy, the amount of water stored by nature is equivalent to that of petroleum and coal, and their formation requires geological years of time scale, which is also a "non-renewable resource" for human society.

Groundwater is renewable, but it's pumped too fast beyond its ability to regenerate and can't be regenerated.

Excessive pumping of groundwater can lead to land subsidence and salinization of coastal areas.
