I do solar energy in a city in Jilin Province.
Because I did it earlier, the brand is good, and the after-sales are good, so the sales are good now. But the city is not very big, so it doesn't make a lot of money.
There is a saying in the solar energy industry: "good people don't like to do it, and people can't do it", especially in the north, solar installation and after-sales are more troublesome than in the south, and there are many problems in winter. The after-sales volume is very large, so you should consider it before drying.
Before you do that, you have to see how solar energy is developing in your local area, and how many new developments are developing. There is also the fact that the contract has been signed for the new solar building as soon as it comes down. Fixed brand, if you can't get a building in the local area, it is not easy to do it, it is best to have a certain relationship with the development company or property.
To be honest, we don't make much money doing solar energy here. Many of them are just maintained, and some of them will be yellow if they can't do it.
Solar energy is an industry with high profits in the early stage and high maintenance costs in the later stage (manpower, materials, solar heat tracing sometimes catch fire, solar water leaks to the gusset, or flows into many homes from the airway to cause losses, and it is inevitable that it will be dry for a long time).

Well, very good, I have a few friends who open a solar water heater factory, and their products sell very well in Inner Mongolia. I haven't asked, and it doesn't seem to be cheap. Because some time ago, I just walked more than 20 units, and he bought them from me because of the high cost of Inner Mongolia.
It's a small hostel. Find someone to install it yourself.

Australia Aosen flat panel solar energy, has been done for decades, and the effect is good! It is one of the world's largest manufacturers of flat panel solar. Titanium liner, blue titanium coating, service life of 50 years.
However, this product is relatively high, I have not been to Inner Mongolia, I don't know how the economic level is, we are now generally in Beijing, Shanghai, Nanjing, Shandong, the market is still OK, if the economy over there can also be a try, after all, now the country vigorously advocates the development of the solar energy industry, there are also some related support.

Our solar water heater controller did a great job over there!
-
I just resigned, and I just went to say that I would give you 1 to 3 months to turn like a high chain Almost all of them are turned positive in three months. And the probation period is 1500 a scum grandson month. It's good to be able to get a thousand in the last month.
Most importantly, I'm in these two months. I didn't pay my salary when I left my job. Said that there is no money, and when there is money, it will be called to the card!
-
It's not good, deducting wages.
-
It's very good, it mainly depends on what position you should judge Chang to hire, the ratio of men and women is more balanced, 12-hour work system, three shifts and two down, not tired is to rely on panic, downstairs said no welfare is true, the salary is now paid on time, it will be a day or two short, a month to the regular exam, after the month to regular, as for the two fools downstairs I don't know why they didn't transfer, the probation period is 1800. As for the issue of resignation without pay, I just want to ask this fool upstairs, didn't you say hello in advance when you resigned from your job? Do you want to go?
Don't deduct who you deduct. Second, goods.

--- Zhang Wenyue, Hohhot Language and Technology Co., Ltd.
In recent years, the demand for solar water heating equipment in new residential communities has gradually increased due to the owner's requirements for diversified residential functions and policy subsidies. However, the solar household water heater is installed and managed separately, and it is used by itself; It is still the use of a hot water system that is assembled in a centralized manner to produce hot water and measure it separately, and people from all parties have different understandings.
Based on years of experience, our company compares the two methods as follows:
Item: Household Water Heater Hot Water System.
1.Installation method South façade wall mounted or top floor roof one per household, roof installation, one system per unit or each building.
2.Management mode Self-use self-management Property company management, sub-household**.
3.The operating cost is used by each household, and the tap water is metered separately and paid according to the flow rate.
4.Heat production mode: natural circulation, forced circulation, a variety of industrial control methods.
5.Water supply temperature No fixed value Water supply at a constant temperature according to the set value.
6.Water supply pressure Open water tank self-flowing water supply, no fixed value; The pressurized water tank is supplied with water according to the tap water pressure and the constant pressure at the set value.
7.Piped cold water Yes, the lower the floor, the more it is ready to use, and there is very little piped cold water.
8.Anti-freeze and heat preservation The traditional heat preservation and anti-freezing of the water tank has a large temperature drop; Pipeline electric companion with anti-freezing, high power consumption indoor water tank, small temperature drop; The collector and pipeline are emptied and anti-freeze, with high thermal efficiency.
9.Cost range: 2300-3000 (ordinary type) 2300-3000 (excluding household pipes and metering water meters**).
10.The appearance of the shape must be scattered and placed near the residents, and the overall shape of the building is not easy to deal with, and it can be combined with the roof modeling, which is beautiful.
Comments: Household water heater technology is mature, widely used, natural circulation, low failure rate, low operating cost;
Disadvantages: The quality of water supply is not high, the user management burden is heavy, the water consumption of a single household cannot be adjusted, and there is a possibility of high temperature scalding.
The hot water system makes the user feel like a hotel, the water is produced at constant temperature and pressure, and there is no water limit, the increase or decrease of the family population and even the family going out are not affected, the disadvantages: the product has high added value, the technical difficulty is large (especially in the northern alpine region), and there are not many manufacturers who master the core technology.
Summary: The use of solar energy is not only energy-saving, but also simple and comfortable, domestic large cities (such as: Beijing, etc.) have rarely seen the trace of solar water heaters, the number of solar water heaters in medium-sized cities is also declining year by year, solar water heating system with its energy-saving, efficient, convenient, and building combination ability and many other advantages, will become the main force of domestic hot water production.

Solar energy is an emerging renewable energy source and is a relatively good energy source.
Solar energy refers to the sun's thermal radiation energy (see the three ways of heat energy propagation: radiation), which is mainly expressed in the so-called solar rays. In modern times, it is generally used to generate electricity or provide energy for water heaters.
Since the dawn of life on Earth, it has mainly lived on the heat radiation provided by the sun, and since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of making food, such as making salt and drying salted fish. In the face of declining fossil fuels, solar energy has become an important part of human energy use and continues to develop. There are two ways to use solar energy: photothermal conversion and photoelectric conversion, and solar power generation is an emerging renewable energy source.
Solar energy in a broad sense also includes wind, chemical, and hydro energy on the earth.
Solar energy is produced by the fusion of hydrogen and helium in the sun's interior to release huge amounts of nuclear energy, radiant energy from the sun. The vast majority of the energy required by humans in solar power systems comes directly or indirectly from the sun. Plants release oxygen, absorb carbon dioxide, and convert solar energy into chemical energy through photosynthesis for storage in plants.
Fossil fuels such as coal, oil, and natural gas are also primary energy sources that evolved over a long geological period from plants and animals buried in the ground in ancient times. The energy contained in the earth itself usually refers to the energy related to the thermal energy in the earth's interior and the energy related to the nuclear reactions.

Compared with electric water heaters and gas water heaters, what are the advantages of solar water heaters in terms of energy saving? A manufacturer of solar water heaters gave the answer:
A solar water heater occupies two to three square meters of space, and each square meter of solar water heater can save 150 kilograms of standard coal and 450 kilowatt-hours of electricity per year. In 2002, solar water heaters saved 5 million tons of standard coal for the country, accounting for the country's building energy consumption; It is estimated that by 2020, solar water heaters can save 50 million tons of standard coal.
The new photoelectric complementary intelligent solar water heater can automatically use electric heating in the weather with insufficient sunlight; But in Beijing, where there are rarely cloudy days, electricity is not used for more than 20 days a year. The use of such a water heater can save 95% of electricity compared with an electric water heater in a summer, and save an average of 350 kWh of electricity per household.
According to my own experience, the distance from the top of the building to the second floor is cold after boiling water in winter.
It's more wasteful, and it depends on where you live, and it's good to have more sunshine. It's also important to buy that brand collar!

The one-time investment in solar energy is relatively large, but it is still relatively convenient to use. It's also safe and energy-efficient, and the solar energy I use can reach more than 70 degrees in summer and 40 degrees in winter. The service life is generally 15 years.
-
Solar energy is good. Energy savings can be saved. I have been using it at home for a year, and I can use it every year from mid-April to the end of November.
Of course, it's too cold in winter to use solar energy. During this period, electric water heaters are hardly used. I also have an electric water heater at home, which I use more in winter.
-
Well, of course, use the sun's heat to save energy for natural combustion.
-
That's where the score is! You say that? There are good and bad!

There are subsidies for solar power generation in Inner Bai and Mongolia, which are:
1) Strong support.
zhi user side light dao volt application;
2) Improve the special price and subsidy policy;
3) improve the management of subsidy funds;
4) increase fiscal and tax policy support;
5) Improve financial support policies;
6) Improve land support policies and construction management.
Electricity prices and subsidy policies are the most important factors restricting the development of the photovoltaic industry.

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.
According to the provisions of the national fiscal and taxation policies, power generators need to provide sales invoices to power supply enterprises, and buyers also need invoices to offset costs, while individual power generation does not have the qualifications of industrial and commercial owners, and the procedures for obtaining invoices are complicated. Taxes over 20,000 are halved.
If you can't get an invoice, it will increase the difficulty of selling power generators, which is not conducive to promotion. The issuance of the State Administration of Taxation will reduce the tax burden on power generators. ”
According to the documents of the State Administration of Taxation, from July 1, 2014, the State Grid Corporation of China purchases power products of distributed photovoltaic power generation projects, and the State Grid Corporation issues invoices, and the monthly sales of power products of power generators exceed 20,000, and the enterprises affiliated to the State Grid shall levy VAT according to 50% of the tax payable. Monthly sales of less than 20,000 yuan can be exempted from VAT.
According to the policy issued by the State Administration of Taxation last year, from October 1, 2013 to December 3l, 2015, the levy rate will be calculated at 3%. Taking Gao Song as an example, if the monthly sales are 30,000 yuan, then the tax amount he should pay is 30,000 3% 50% = 450 yuan.
For every 1 kilowatt-hour of electricity generated by residents, the state subsidizes yuan; The state purchases inexhaustible self-generated electricity from residents at the price of desulfurized coal electricity, which is also yuan per kilowatt-hour. Based on the average installed cost of 1 kilowatt of a distributed photovoltaic power generation system of about 10,000 yuan, if the average daily power generation of an 8 kilowatt system is 30 kWh and the household electricity consumption is 5 kWh per day (no more than the first level of electricity price), the investment will be recovered in about 8 years.
According to the same calculation, it will take 9-10 years for a 10 kW distributed PV installation to pay for itself.
The payback period for a home PV power plant is between 8-10 years on average.

You can only say that you are looking for a cost-effective teaching.
Domestic brands are better Huangming, Four Seasons Muge, Sun Rain, Tsinghua Sunshine, these prices should be more than 4000.
Don't think about the 3000 or so wall-mounted machine
In winter, there will definitely be a strike, and they will rely on the electric heating in the indoor unit to send you hot water, which is the trick of some manufacturers.
Without the sun, there would be no such beautiful world.
Solar street light is a lighting device that uses solar energy to generate electricity, which is composed of solar panels, batteries, controllers, LED lights and brackets, etc. >>>More
The brand of solar water heater, I still know better, every time I buy, I will go to the top ten brand network maigoo to understand the brand of solar water heater, I think it is still Huangming, Sangle, Tianpu, Huayang, Yijianeng These well-known brands are of better quality, and I use Huangming's at home, and there have been no problems in the past four years!
