What model is suitable for solar rain solar water heater household type and what is the price?

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.

1.Look at the brand. To choose the products of Huai Jing manufacturers, it is best to have excellent quality brand, so that it is possible to have excellent product quality and excellent after-sales service system and commitment.

2.Look at the quality of the vacuum tube. The vacuum tube is a key component of the water heater, and the amount of heat obtained by the vacuum tube under the same external conditions directly affects the water temperature.

When purchasing, carefully observe the coating on the glass tube in the vacuum tube, the color is generally black, dark blue or dark gray, the coating color is uniform, the film layer has no scratches, no peeling or peeling, there are no stones on the glass, the support is placed properly, and the lead is not loose.

3.Look at the selection of materials and process technology for the insulation layer and liner. There is a layer of insulation material between the shell and the inner tank of the solar water heater tank, which plays a very key role in hot water insulation, and the service life of polyurethane insulation materials can reach more than 15 years.

The inner tank is where the hot water is stored, preferably with a stainless steel plate, with a thickness of about millimeters. In short, consumers should choose imported polyurethane and water tanks with thick insulation layer.

Because the insulation layer and inner tank of the water heater are inside, it is not easy for consumers to see, so it is better to buy products with a good reputation in the market and guaranteed in terms of product quality, performance, and service.

4.Look at the thermal performance indicators. It is not that the higher the temperature of the water in the tank, the better the thermal performance, but the higher the average daily efficiency, the better, and the lower the average heat loss coefficient, the better.

The second is to see whether the pressure test of the water heater is qualified, and if the pressure test does not meet the standard, it will easily lead to the leakage of the water heater, which will waste hot water and cannot be used.

5.Look at the bracket design. The bracket should have sufficient strength and rigidity.

6.Look at the reflector design. When purchasing, attention should be paid to whether the reflector design of the product can make full use of the heat-absorbing surface of the vacuum tube, and whether the vacuum tube can receive light to the greatest extent.

In addition, in terms of key technologies, consumers should also pay attention to identifying: (1) different colors of vacuum tubes are due to different absorption layers, and the effects are also very different; (2) Most companies do not use reflectors, because after a period of use, the reflector becomes a decoration, there is too much dust, there is no effect at all, and from the perspective of windproof, it does not support the use of reflectors; (3) The water storage tank is not the thicker the insulation layer, the better, after reaching the critical thickness, the thicker the insulation layer is useless; (4) The thickness of the water tank plate, for the non-pressurized water tank, is almost the general standard of second-tier manufacturers, which can already ensure the service life of the water heater, but why is there it, it is a famous brand product, **expensive, the cost increases a little, and the sales ** are 50% more expensive than others.
