Solar energy at home, 6 people use, if you buy solar energy, how many collector tubes are good.

Mulberry Solar.

Choosing solar energy, from a large perspective, depends on these points: product quality, price, after-sales.

The inner liner of Mulberry Solar is made of one-time roll molding, which is more durable than other brands (the others are welded and formed). In addition, Sunle is the only company in the solar industry that promises free maintenance of natural disasters, and promises that the manufacturer will be responsible for repairing and replacing the use problems caused by natural disasters such as strong winds and hail. Sangle Solar uses three high-vacuum tubes (high temperature resistance, cold resistance, high pressure resistance), and each vacuum tube is printed with the logo of Sangle to ensure that it is produced in the original field, and the heat absorption effect is guaranteed.

The bracket used by Sunle Solar is a cold-rolled one-time formed steel plate, with good hardness, and a double-layer paint process, which will not rust for life.

24 pipes are OK, 24 pipes hold about 245 liters = 42 liters x 6 people, you have 10 famous brands on the brand, but ** much higher, it takes about 4000 yuan to install it, if you want to spend less money, you can buy a second-tier brand, anyway, it is also a regular manufacturer out of things, the quality of one-stop production, ** will be much less, and it will be about 3200 yuan to get it down.

It is recommended to choose a water tank with a net capacity of 180L-200L products, there are elderly people and children at home, in addition to bathing, the usual washing, kitchen will use hot water, because solar energy is a one-time investment product, one step in place, buy too small to want to change it.

And it is recommended that you pay attention to choosing a good dealer when choosing a brand, so that the after-sales service is guaranteed, and also pay a little attention to the installation materials, try not to package (the price of the host material), but to settle separately (the host ** + the actual material **), so as to avoid individual dealers cutting corners in the material, do not choose too low solar energy, a penny for the price, the old saying is dead, but also responsible for your own interests.

Now the solar market is relatively chaotic, many manufacturers rely on advertising to improve their popularity, it is recommended that you choose Samp, Tsinghua Sunshine, Tianpu and other well-known brands.

Summary. Hello there! It doesn't cost electricity, it can bring radiators, just use a solar water heater to drive the radiators for heating.

Hello there! It doesn't cost electricity, it can bring radiators, just use a solar water heater to drive the radiators for heating.

The daily heat collection of solar water heater is relatively small, if it is to be used to drive the radiator heating, it is necessary to equip the solar water heater with a large-capacity heat tank, and the number of tubes of the solar water heater is increased, and more heat collector tubes are collected to heat the water, and the heated hot water is stored in the large-capacity hot water tank, which is convenient for heating at night.

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.
