The future of solar energy production is bright.
First, it is possible to largely replace the currently dominant coal-fired power plants, protect the planet and reduce sulfur dioxide emissions.
Secondly, the application of a large number of distributed solar power generation methods will effectively improve the quality of life of people in remote areas and solve the electricity problem of people living in remote areas. areas where large electricity networks are difficult to reach. due to cost and technology.
Of course, to achieve the above goals, several technical issues need to be resolved:
1. The first is whether the conversion efficiency of solar panels can be greatly improved. For example, the conversion efficiency of large-scale solar panels will increase from the current 18% to around 30% while ensuringachieving a reduction in costs.
2. Solve the power supply network security problem of large power grids subject to the impact and shock of photovoltaic power generation. Otherwise, large power grids would not be able to withstand the impact of a high proportion of solar photovoltaic power generation.
3. Significantly reduce the cost of photovoltaic solar power generation equipment, making the cost per kilowatt equal to or even lower than the cost of conventional thermal power generation. At present, the cost of conventional thermal power is about 5,000 yuan per kilowatt, while the cost of solar photovoltaic power generation systems is about 10,000 yuan per kilowatt. At the same time, the effective annual electricity generation duration of conventional thermal power is more than 6,000 hours, while the effective electricity generation durationThe electricity generation of photovoltaic solar power systems is only 2,000 hours.
In summary, although the future prospects of solar power generation are theoretically bright, if the above three points cannot be effectively improved, solar power generation will not be able to not play a leading role for many years.
Is photovoltaic solar energy production in rural areas reliable?
No stopping.
The installation process of the photovoltaic power generation system is complicated and requires high attachments, but the buildings and facilities on which the photovoltaic power plant is based must be legal. In order to achieve better lighting through solar panels, many users have carried out major construction work on the roofs of buildings, built photovoltaic cabins, and built wooden supports.rics several meters high to store solar panels. The supports are illegal structures, leading to their demolition. the urban management service.
If the installation of a photovoltaic power generation system requires approval from urban management, safety supervision, planning and other departments, photovoltaic systems remain still a niche in many places, with small installed capacity and little attention from local authorities. This has led urban management departments in many places to be flexible in the area of photovoltaic systems.
Notes:
When installing a photovoltaic panel array, you must take into account the azimuth and inclination angle of the installation. Blockages between Blue Sky panels of Jiaotong University should be avoided. Including surrounding buildings (pottelephone water, eaves of houses, etc.).
The stability and firmness of the bracket placement (consider local weather data, such as sunshine hours, weather disasters, storms, etc.).
Plot the distance and location of the combiner box. Try to keep trace distances short and even. Terminal blocks must be secure to avoid false connections or disconnections.
Battery terminals should be firm (never short circuit) and pay attention to polarity when installing to avoid explosions and fires. The application process for national grants is as follows:
(1) Apply for grantsResidential distributed photovoltaic power generation projects and poverty alleviation photovoltaic projects must meet the following conditions:
p>
a Complete the file in accordance with the procedures.
b. The project has been completed and put into operation, meets the relevant conditions for grid connection, and has completed acceptance of grid connection and other grid access works.
(2) With the exception of photovoltaic poverty alleviation and residential photovoltaics, other photovoltaic energy production projects that require state subsidies:
In principle, they should adopt competitive allocation methods such as competitive bidding and apply through project owners, the competitive ranking method is used to determine national subsidy projects and subsidy standards . The allocation of market competition and tenders for photovoltaic projects distributed by non-residents are implemented under the guidance of the provincial energy authorities. Energy authorities in various cities are organizing requests for pprojects. For specific application requirements and procedures, please refer to “Guangdong Provincial Energy”. The Administration forwarded the Notice of the National Energy Administration on the 2019 Notice “Notice on Issues Related to the Construction of Wind and Photovoltaic Power Generation Projects” (Guangdong New Energy Letter [2019 ] No. 358) and other relevant documents, or consulted the energy authorities.
For projects that meet the application conditions, the electricity supply company will actively assist you in applying for subsidies in accordance with government regulations. First, it will be submitted to the Ministry of Finance, the National Development and Reform Commission and the National Energy Administration after review and approval by provincial finance, price and energy authorities. The Ministry of Finance, the National Development CommissionDevelopment and Reform and the National Energy Administration organize the review of submitted projects and include qualified projects in the subsidy catalog for announcement. If the project is included in the National Grant Catalog, the state will allocate grant funds in accordance with the plan.
Reliable. Photovoltaic energy production is a new energy project which is strongly supported and promoted by the State, like wind energy production, certain financial compensations are provided mainly for large ones. -area projects. It is also a promotion project with large investment and slow results, saving power generation resources.
Photovoltaic power generation involves letting photons shine on the metal, then absorbing the energy through the metal and converting it into solar cells. Solar energy is currently a source of energyinexhaustible renewable, clean, reliable and usable for a long time.
Future Trends
Solar photovoltaic power generation will occupy an important place in global energy consumption in the near future. It will not only replace some conventional energy sources, but also become the main source of energy. of global energy supply. It is expected that by 2030, renewable energy will account for more than 30% of the total energy structure, and solar photovoltaic power generation will account for more than 10% of the world's total electricity supply.
By 2040, renewable energy will account for more than 50% of total energy consumption, and solar photovoltaic power generation will account for more than 20% of total electricity by end of the 21st century, renewable energies; will represent 50% of the energy structure. More than 80%, solar energy production will represent more than 60%. These figures are enough to show the development prospects of the solar photovoltaic industry and its important strategic position in the energy field.
