Home solar, solar home heating

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.

Introduction to solar heating.

Solar heating refers to the system that converts the dispersed solar energy into convenient hot water through collectors (such as flat solar collector panels, vacuum solar tubes, solar heat pipes and other solar energy absorption collection equipment), and transports the hot water to the heating end (such as floor heating system, radiator system, etc.) to provide room heating, also known as solar heating system, referred to as solar heating. Solar heating is an environmental protection project, which is different from ordinary heating methods in that the heat source is different, that is, ordinary heating is coal, electricity, oil, gas, etc., while solar heating is the use of pollution-free, renewable solar energy.

Advantages of solar heating for home.

Use all year round. It can be used for solar heating in winter (also for year-round use) and bathing all year round. This is a revolutionary advancement in solar water heaters and a major technological breakthrough in solar energy applications;

Low investment and low fees. The one-time investment of solar heating system is significantly lower than the initial investment of central heating, oil-fired coal-fired boilers, etc., does not need approval, and the daily operating costs are much lower than those of central heating, oil-fired gas-fired electric boilers in the same heating situation, and even much cheaper than earth heating and air conditioning, and can also realize the bathing function throughout the year, which solves the problem that the equipment of the system is idle in spring, summer and autumn, and the depreciation of equipment is accelerated.

Apply 24 hours a day. You can use it for as many days as you want every year according to the temperature, and you don't have to worry about the high cost of using gas boilers or air conditioners, so you can only drive it for 2 hours a day, and the rest of the time is hard to support.

Intelligent control. The perfect combination of solar energy and electricity, dynamic and intelligent operation mode, daily expenses are minimized. The solar heating and bathing system consists of a high-temperature solar heating system on the roof and an indoor computer intelligent control system.

Easy to set up. In many areas, on a sunny day, 24 hours a day can be powered by solar energy. If you feel that you need a higher temperature indoors on a rainy day or at night, you can supplement it with electricity.

The application of solar broadband technology and electric frequency conversion technology enables the energy use of solar energy in the whole system to reach a maximum proportion of 60 95.

Safe, clean and pollution-free. The operation is simple, and it is convenient for the elderly and children to use. Avoid cold-related illnesses and create a healthy, comfortable and warm new life for you.

As a clean and pollution-free heating method, solar water heaters have been recognized by the public, and various problems have been accompanied by our use. A kind of solar water heater that uses ceramic materials instead of conventional glass vacuum tubes and metal plates as collectors, which is called black and porcelain, does not need to worry about problems such as frying pipes, freezing tubes in winter, long-term air drying to reduce life and heat collection efficiency.

With current technology, home solar power for heating is technically reliable. But the biggest problem is that the cost is too high!

For example, if you have a heating area of 100 square meters in your home, you need at least about 4 kilowatts of power to get the necessary heating effect.

At present, the cost of a kilowatt solar photovoltaic power generation device needs 10,000 yuan, and 40,000 yuan of investment is required for 4 kilowatts.

What's more, the fatal flaw of solar power is that it stops generating electricity as soon as it runs out of sunlight, and the long winter nights are exactly when electricity is most needed. Therefore, the complete technical solution needs to configure a group of battery packs with large capacity, add several kilowatts of solar panels to power (charge) the batteries of the battery pack, and use the electricity in the batteries to heat when the power cannot be generated at night.

How many battery packs do you need to drive a heating load of 4 kilowatts? Including additional solar panels, it is estimated that another 100,000 yuan may not be enough.

Therefore, even if the technology is mature and reliable, the home heating system, under the premise of high cost, is difficult to detach from the support of the grid system at night or in rainy and snowy weather, and completely independent heating, the cost is too high and not feasible.
