Is it really that expensive to install a home solar power system?

Yes, not cheap! Generally, ordinary families all bring more than 10w

Depending on what appliances you have in your home, the more powerful the appliances, the less cost-effective they are, and you may have to use many times the price to install solar power.

Look at the place, the main thing is the sunshine coefficient problem!

It should not be less than 25 watts. You can do the math yourself!

3 years of professional in Guangxi.

Hello! First: the area of the photovoltaic panel depends on the size and model you choose, the size of our board is: 1640mm x 990mm x 35mm;

Second: the market is about 10 yuan w (our price is including the whole process, installation, etc.), and there are also higher**. 3kw is 30,000.

Third: 3kw generates 3 kWh of electricity in an hour, and you can roughly estimate the amount of electricity generated according to the sunshine hours on your side.

The area and ** of the photovoltaic panels are analyzed based on the situation of our company for your reference.

Do you have to ask about an on-grid or off-grid system?

1. Household solar power generation is done through the sun, as long as we can use it reasonably, it is still more reliable.

2. Under the standard quality, the grid-connected power generation system can generally be used for more than 20 years, and the solar panels of the off-grid power generation system can also be used for more than 20 years, but the battery (3-5 years), controller (5-10 years), inverter (5-10 years) and other components need to be replaced regularly; The home system is easier to do for villas and self-built houses with independent roofs.

3. In general, if the formalities are completed, the grid connection can be merged, and the excess electricity can also be sold to the power company, which has precedents.

In recent years, with the implementation of the "dual carbon" strategy and the help of various national macro policies, the rapid development of new energy industries such as distributed photovoltaics, household photovoltaic projects have become more and more popular among the masses. More and more people are curious about whether home solar photovoltaic power generation is cost-effective, so let me answer them one by one.

First of all, the light conditions of the region have an impact on the income of power generation. Photovoltaic power plants rely on sunlight to generate electricity, which requires good light conditions, and the roof cannot be blocked by surrounding houses and trees. The better the light conditions, the higher the power generation efficiency, which can save electricity bills and obtain benefits.

Moreover, traditional winter heating not only consumes limited resources, coal resources and pollutes the environment, but household photovoltaic power generation itself does not use fuel, does not emit any substances including greenhouse gases and other waste gases, which is more cost-effective and environmentally friendly.

The second point is that the area of the roof determines how much installed wattage can be placed, and the number of kilowatts that ordinary households need to install for solar photovoltaic power generation is generally based on the roof area or household electricity consumption. Taking the 400-500W board that is used more as an example, it is generally calculated at 225W per square meter, such as the installed capacity that can be installed in 100 square meters. Installed capacity has a direct impact on the amount of electricity that can be sold per unit of time.

The third point is the conversion efficiency of the module itself. In simple terms, the conversion efficiency of a photovoltaic module can be described as the conversion rate from sunlight to electrical energy. This parameter directly determines the quality of the module's power generation capacity.

The conversion efficiency of photovoltaic modules is affected by many factors such as the type of material of photovoltaic modules, cell technology, construction and installation angle, the degree of cell attenuation, etc., and the efficiency of typical photovoltaic modules is in the range of 15 to 20, and the higher the conversion efficiency of the module, the more it can play a role in reducing the cost of power generation.

The fourth point is the local electricity price that everyone is most concerned about and is integrated into the national grid. The average electricity price of grid-connected photovoltaic power generation in the life cycle of grid connection is about yuan, the current average electricity price of residents, the average degree of electricity gap yuan, now the state has a kilowatt-hour subsidy for solar power generation, and each kilowatt-hour of electricity subsidy yuan (including tax), there are local subsidies in individual areas such as Hefei, Jiangxi, Zhejiang, Luoyang, Henan and other places.

The installation of household solar photovoltaic is beneficial and harmless, not only has national policy subsidies, high yield and stable income, but also can meet household electricity, and does not require special maintenance, which is very worry-free and labor-saving. Therefore, if you want to install distributed photovoltaics, as long as you find the right conscientious brand, then you will get safe and stable good income. As a brand that has been deeply involved in the industry for 20 years, LONGi Green Energy has advanced module technology, stable and reliable power generation, especially the advent of a new generation of product Hi-Mo 6, which further reduces battery attenuation through technology iteration, which can bring higher benefits to end users.

1 kilowatt is about 10,000, 2 kilowatts 2 is rising, 30 million to 5 kilowatts is basically 10,000 per kilowatt, and more than 10 ** will be cheaper. Solar energy refers to the energy released by a thermonuclear reaction inside the sun. The Sun is a large, hot star that is constantly undergoing thermonuclear reactions, radiating large amounts of energy, some of which reach Earth.

Main advantages: The sun reaches the earth with a lot of energy, part of which is used by plants and converted into bioenergy, and part of it is used by the evaporation of water and converted into water energy, and a lot of energy is wasted.

The sun is a huge natural energy source, and the use of solar energy has great prospects. In order to make more efficient use of solar energy and convert sunlight into heat, electricity, chemical energy, etc., scientists have studied the use of large-area light devices to concentrate solar energy and convert it into water or electricity, and have designed and manufactured a variety of solar energy devices.

Do you have any other questions?

Solar energy is endless, and it absorbs solar radiation from the earth's surface.

That's 10,000 times the world's energy needs. If 4% of the world's desert areas were converted into solar energy, the electricity generated would be enough to meet global demand. Solar energy is safe and reliable, it can be found everywhere without the impact of the energy crisis and the instability of the fuel market, it can provide electricity nearby, it does not need to be transported over long distances, it does not need to be transmitted over long distances, it does not consume fuel, and it has low operating costs.

A small sun for home use.

The system is very good, and the following is its advantage.

1. Safe and reliable, no noise, no radiation, no consumption, no mechanical rotating parts, failure rate.

The construction period is short, the scale is free, and the disassembly and assembly are simple.

3. Instantaneous use, low cost of demolition and damage, easy to combine with construction, no need to bury high wires, saving vegetation and environmental damage and engineering costs caused by long-distance cable laying.

4. Stable voltage, high-quality power supply, suitable for all kinds of power facilities, very suitable for use in remote areas such as mountains, farms, islands, high-speed highways, and other remote areas, and is an ideal emergency backup power supply.

Safety issues should be a book round do not have to worry, when choosing to choose a brand with Baozhou attack barriers, according to the operation specifications are no problem.

But the use of personal feeling is not Zen to take practical, the peak period of electricity consumption of ordinary people in our country is generally at night, and the night of winter is the peak period of electricity consumption, and the electricity that is about to be used is not generated later, and the use of electricity at night is completely dependent on storage, if there are many people, it is a problem.
