Hello! I would like to ask which brand of solar generator is guaranteed now? is suitable for home us

Generally, it is more suitable for places without electricity, Yutian solar generators.

It's all pretty much the same. The conversion efficiency will not be too high. If there is a place with mains, there is no need to do this.

How is the quality of the product of the solar generator, the main considerations are as follows:1Whether the system is properly configured.

It is important to have a good understanding of the local climatic conditions, such as solar radiation, the average temperature of the installation site, the type of battery used and its performance. In this way, we can design a reasonably configured solar power generation system, and the life of the solar generator will have a great impact on 2Consider the power of the electrical equipment, so that this will affect the service life of your battery and other related conditions, 3

Also consider the interval between the two longest rainy days, and try to ensure that the battery can be replenished in time. 4.The battery board should be selected, and the battery board with a good IV test curve should be selected, and its low child life should be considered, so as to ensure the charging efficiency of the battery board.

I've seen a lot of people who mismatch customers and don't tell customers how big the battery panel is, just tell people how big my output power is, which is actually very bad. To put it bluntly, you have a large battery and inverter, and it makes no sense to say that my output power is very large, the most important thing is the amount of electricity generated by your solar panels every day.

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 price is 150-180 yuan, including other costs such as materials and so on, and the purchase is optimistic about whether there is reliable after-sales solar panel power generation in the local area, and the group size is recommended to bid, mainly because the power transformation and storage power equipment is very expensive, and the conversion rate is up to 17%-20%, and the efficiency is very low, which 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.

Photovoltaics

Photovoltaic power generation system.

Referred to as photovoltaic, that is, photovoltaic power generation system, is the use of semiconductor materials.

The photovoltaic effect is a power generation system that converts solar radiation energy into electrical energy. The energy of the photovoltaic power generation system** is a clean, safe and renewable energy source from the inexhaustible solar energy. The photovoltaic power generation process does not pollute the environment and does not damage the ecology.

The investment cost of the solar power generation system is higher, and the above types of electricity are enough. This is an off-grid solar power system. A certain Tao, search store:

Entron Solar.

Solar generators have their advantages and of course their disadvantages.

First, the advantages of solar generators.

1. Independent power supply, not limited by geographical location, no fuel consumption, no mechanical rotating parts, short construction period, arbitrary scale;

2. Compared with thermal power generation and nuclear power generation, solar power generation will not cause environmental pollution, is safe and reliable, noiseless, environmentally friendly and beautiful, has a low failure rate and a long service life;

3. It is easy to disassemble and assemble, easy to move, low engineering installation cost, can be easily combined with buildings, does not need to pre-embed high transmission lines, and can avoid the damage to vegetation and environment and engineering costs when laying cables over long distances;

4. It is widely used in all kinds of electrical appliances, and is very suitable for families in areas lacking electricity and no electricity, as well as household appliances and lighting appliances in remote places such as villages, grasslands, pastoral areas, mountains, islands, and highways.

5. It is permanent, as long as the sun exists, solar power can be used for a long time with a one-time investment;

6. The solar power generation system can be large, medium and small, from a medium-sized power station of one million kilowatts to a solar power unit that is only used by one household, which is incomparable with other power sources.

Second, the shortcomings of Tianyang energy generator.

1. Affected by weather changes. The amount of electricity generated varies from time to time, and the weather conditions vary from day to day. Since solar panels rely on sunlight, even small clouds can affect power generation and power output.

In rainy and cloudy weather, you will find that solar generators can provide very little electricity.

2. Unless the excess electricity generated during the day is stored, it is impossible to use electrical appliances at night, whether it is for emergency or to provide electricity to the residence. The current typical method of storing solar energy is to use 12-volt batteries. A solar power system can use standard car batteries, but due to frequent use and charging, the best battery is a deep-cycle seawater battery.

In most cases, 4-6 batteries are combined to form a battery pack that can store power for a few days to a week in case it is urgently needed.
