What is the difference between ruby solar, brand solar energy and general solar energy?

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.

This is equivalent to the fact that general shoes and clothing are the same as brand shoes and clothing, and there must be a big difference.

There's a little battery in there.

There are many, many kinds, and if you want to make it into a solar ......

What do you mean? That's not an exhaustive question.

Because there is sun in the sky, so solar energy.

Light energy can make plants grow, but it can also make ugly**.

Photosynthesis converts carbon dioxide into oxygen.

1. Unlimited energy is widely available, and the lowest cost is hot water. As long as there is sunlight, it can carry out photothermal conversion and can operate all year round.

2. Green environmental protection products, solar energy, as a clean renewable energy, has incomparable advantages of other energy sources: no environmental pollution, no potential safety hazards.

3. Long service life, the service life of the main component vacuum tube is about 15 years, and after the expiration replacement, other components can continue to be used for a cycle.

4. It can be used with other energy sources to achieve all-weather operation.

5. Significant economic benefits. One investment, long-term benefits are the distinguishing features of solar water heating systems. After years of practice, it has been proved that under normal circumstances, solar water heaters can fully recover their investment within 2 to 4 years.

As a new energy source, solar energy has three major characteristics compared with conventional energy:

First: it is the most abundant energy source available to humans. Clean, pollution-free, environmentally friendly, inexhaustible.

It is estimated that the sun has consumed 2% of its own energy over the past 1.1 billion years. In the future, it will be enough to supply the human beings of the earth for billions of years, which is really inexhaustible.

Second: Wherever there is solar energy on the earth, it can be developed and utilized on the spot, and there is no transportation problem, especially for rural areas, islands and remote areas where transportation is underdeveloped. It is generally believed that in the area within 50 60 degrees of north and south latitude, the annual sunshine time in this region is 1600-2400h (hours), with abundant solar energy can be used, as long as the initial cost is a certain price, invest a sum of money, build a good solar energy utilization device, the energy will continue to be sent to the door, free of charge, during which only a small amount of equipment maintenance costs are spent.

Third: Solar energy is a clean source of energy. In the development and utilization, there will be no waste residue, waste water, waste gas, no noise, and no ecological balance. It will never cause pollution or public pollution.

Fourth: solar energy does not increase the thermal load on the earth, which is a particularly important advantage of solar energy, so the system using solar energy is also called the invariable energy system. Because we use solar energy to do work, although it eventually becomes heat, if we don't use it to do work, it will eventually become heat.

Fifth: solar energy safety and availability. Nuclear power generation will have the risk of nuclear leakage, once the nuclear leakage will cause a great ecological crisis, but solar energy is absolutely not like this, it is very reliable.

Solar energy is divided into photovoltaic and solar thermal 2 parts, the specific principle of the photovoltaic part is not very understood, the cost is very high, I contact is sold by w in the market should be about 20 yuan, the more months cheaper, an inverter is also very expensive, the specific number is not clear, with the current electricity price to calculate more expensive, because the after-sales is quite a lot, solar thermal price ratio is good, for example, the use of hot water in the home is very convenient, as long as there is the sun is generally not needed electricity, a family of four to buy a 3000 or so is enough, you can't use a few kilowatt-hours of electricity a year (provided that you can use it, don't open the electric heating for a long time, set it to manual, under manual heating on cloudy days, if it's automatic 24 hours a day, it will cost electricity, and you can calculate it yourself A heating rod is at least).

Recyclable, clean and pollution-free.

The advantages of solar energy are many: clean, cheap, and inexhaustible.

Solar energy is an infinite source of energy that will not be exhausted for hundreds of millions of years.

The sun can be used for hundreds of millions of years without being consumed.

Clean and cheap.

Inexhaustible.
