What is the quality of solar energy in the four seasons? What about the price?

solar power generation, the output per square meter is about 12w, and the cost per square meter is about 1,5 yuan. The larger the area, the lower the price.

In p>213, the photovoltaic industry was investigated by anti-monopoly in Europe and America. Overcapacity led to the closure of a large number of photovoltaic industries in Zhejiang, and the price of solar energy fell. This can be checked online at any time

It is suggested that the price of each solar water heater is 15-18 yuan includes other expenses, such as materials, etc., and it is recommended to consider the local climate, installation conditions, economic price and durability

1. Local climate: the solar tubes of solar water heaters will not freeze in winter, but many people will find that they are basically frozen except the solar tubes during actual use. It's really a waste to pick up half a bucket of cold water before taking a bath.

2. Installation conditions: the water pressure is not good, and the floor is high. It is recommended to wash and sleep when preparing to install a mixture of solar energy and electric heating. Related auxiliary equipment, including booster pump and controller, will force you to spend a lot of innocent money, and you always feel that it is difficult to ride a donkey

3. Economic price: in terms of use price, the price of solar energy is over 3, yuan, the electric water heater is about 1,5 yuan, and the gas hot water is about 2, yuan. Although solar energy does not need electricity, experienced friends know that solar energy can't be used without electricity, so let alone saving electricity. As far as the utilization cost is concerned, the price of natural gas pipeline gas is the least, followed by electricity. In terms of comprehensive cost, it costs 1,5 yuan more to buy solar energy, which is equivalent to 3, kWh, enough for you to use for several years.

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

solar energy as a clean energy source in the long run, but due to the limitation of artificial technology, The conversion rate is not as high as that when we directly plant trees and boil water with wood. It is recommended to choose carefully.

After all, the ladder electricity price, ladder water price and new energy promotion policy were selected by the votes of sitting in the Great Hall of the People, and we have no idea that it represents us. Every hearing only has how much it has gone up, and it has never gone up or down.

The above is purely wishful thinking. If there are similarities, it is purely coincidental.
