How to choose solar photovoltaic power generation equipment

Solar power generation technology is now very mature, and the most important thing to choose is to have sufficient power generation, stable operation, reliable warranty and after-sales freight service.

In order to choose the right one, we must first understand the composition of the system and the core that affects the power generation. The solar power system consists of solar panels or solar modules, inverters, brackets, distribution boxes, cables, and other auxiliary materials. The core components are solar modules and inverters, which directly determine the amount of electricity generated and how many years of electricity are generated.

The 5kw system can generate about 23 kWh of electricity a day in the summer when the amount of light radiation is at its highest.

The amount of electricity generated by a solar panel is determined by the efficiency of the cells, the materials used to assemble the solar panels, and the process. There is generally no problem with the process and materials of big brands, but there are also high and low cells, and the difference is also very large, so it is necessary to ask about the efficiency of cells and modules. 250W monocrystalline cells are sufficient, the standard specification is 1650mm*992mm, and the modules are generally in; 250W multi-Si cells are sufficient, standard specifications, and modules are generally in.

It is not recommended to install solar photovoltaic equipment by yourself, it is best to install a complete set of solar photovoltaic equipment, and installing it yourself may cause circuit damage and damage to photovoltaic equipment. Recommend several solar photovoltaic power generation companies for you, they can complete the integrated process service from design, installation and grid connection, and only need you to check the plan and sign to confirm that you are present at the time, so as to avoid the trouble of time.

Advantages of solar photovoltaic power generation:

1. Solar energy is inexhaustible, and the solar radiation energy borne by the earth's surface can meet 10,000 times the global energy demand! As long as 4% of the world's deserts are installed with solar photovoltaic fragments, the electricity generated can meet the global demand!

2. Solar power generation has no moving parts, is not easy to be damaged, and is complex to maintain, especially suitable for unattended use.

3. Solar power generation will not cause any purification, noise and other public hazards, and has no adverse effects on the environment, which is an ideal clean power.

4. Solar power generation is safe and reliable, and will not be affected by the energy crisis or the fuel market fluctuations.

5. Solar energy can be supplied everywhere, and it can be supplied nearby, without long-distance transmission, which prevents the loss of long-distance transmission lines. The sun does not need fuel, and the cost of operation is very low.

6. The fragmented establishment period of solar power generation is short, convenient and sensitive, and the amount of solar energy can be arbitrarily added or increased according to the increase or decrease of load to avoid waste.

Many manufacturers are color steel tile roofs or small flat floors, and they need high cooling costs in the hot summer. Photovoltaic panels have the function of thermal insulation, and after laying photovoltaic modules on the roof, it can effectively reduce the temperature of the factory downstairs. It can make the downstairs workers more warm tasks, and the consumer equipment can also run bumpy, which directly reduces the cooling cost of the enterprise's air conditioners, fans and ice cubes.

1) Solve the problem of people without electricity and electricity consumption in poor areas. Every 3,460 yuan investment in independent photovoltaic can solve the electricity consumption of one person; However, investing in the power grid requires 13,385 yuan, which is twice that of independent photovoltaics.

2) Achieve targeted poverty alleviation. 2015 In 2017, about 2 million poor households will receive a stable income of 3,000 yuan per year in the next 20 years, which is equivalent to providing 6 billion yuan of poverty alleviation funds every year.

3) Promote the integration of the central and western regions. The western region attracts photovoltaic manufacturing enterprises to invest with low energy and labor costs. At present, 57% of the polysilicon production capacity is in the western region, and this figure may reach 76% by the end of 2018. The new production capacity of other links is basically in the west.

At the same time, by the end of 2016, 40% of the country's photovoltaic installed capacity was in the western provinces, making full use of the abundant local solar energy resources and desertified land, and effectively improving the desertification of the land.

4) Activate private capital and promote the diversification of the main body of the energy industry. From extraction to power generation, traditional energy is basically controlled by state-owned enterprises. The photovoltaic industry, especially distributed photovoltaics, has broken the geographical factors of traditional energy, lowered the entry threshold, and provided the possibility for a wider range of small and medium-sized enterprises and the public to participate in the energy industry.

Among the enterprises with large holdings, state-owned enterprises and private enterprises each account for half of the country, while small-scale holders are mainly private enterprises. The characteristics of photovoltaic power generation determine that it is the main force to promote the diversification of the main body of the energy industry. This shift in role will have a significant and far-reaching impact on the evolution and development of the energy system.

5) Intensive land use, popularization of renewable energy, layout of energy Internet, photovoltaic power generation and other industries complementary development of new forms have become one of the measures for the development and transformation of many regions, and on the basis of the original function, the original building has increased the effect of power generation and energy saving, and improved the utilization rate. The development of household photovoltaic has brought renewable energy into thousands of households, let ordinary people understand renewable energy, and improve their awareness of energy conservation and emission reduction. The development of distributed photovoltaic has laid a solid foundation for the future development of the energy Internet.

6) Save water resourcesFrom the perspective of the whole life cycle, the water consumption of photovoltaic power generation is only 50% of the water consumption of coal power, and vigorously developing photovoltaic power generation can effectively save water resources.

Solar photovoltaic is a renewable and clean energy source with several advantages. First of all, the solar PV system does not require fuel, so it does not produce pollutants and greenhouse gas deficiency precursor emissions, helping to protect the environment and reduce climate change. Secondly, solar PV systems are less expensive to operate because they do not require additional costs such as fuel or lubricants.

In addition, the solar PV system can be transported in off-grid or on-grid mode, increasing its flexibility and reliability. Finally, solar PV systems are characterized by long life and low maintenance costs, so they can reduce overall energy costs.
