The development of science and technology has led to the progress of solar power generation. Throughout the solar pv industry abroad, has become increasingly mature, the domestic market is also hot. How far can solar power go? We analyze its development prospect together.

First, the future of solar power generation is bright

View the problem from the point of view of onlookers, from the point of view of a few years ago: solar power may be largely replace currently dominated by coal-fired power stations, to view now: solar power has replaced coal. First, global warming is caused by the increase of carbon dioxide. Solar power generation is characterized by low carbon and environmental protection. On the other hand, the application of distributed solar power generation can effectively improve the quality of life of people in remote areas and solve the problem of difficult transmission of power due to the cost and technology of national power grid. People in remote areas use solar energy to generate electricity to solve the problem of electricity.

2. The future of solar power -- the development of domestic solar energy has a bottleneck

There are two bottlenecks in the development of solar power:

1. Direct current generated by solar power generation can only be directly used for pure resistance electrical appliances such as lighting and heating; If used in refrigerators, washing machines, color TV sets, air conditioners and other household appliances can only be used by converting inverters into ac power, the investment and operation maintenance costs will be increased.

2. Domestic solar power generation is usually installed on the roof and the wall facing the sun, which requires unified design and planning. Some places with poor lighting are restricted. Combining the first two points, the use of solar power in rural cities is restricted.

3. The future of solar power - the problem to be solved now

All technologies that can be widely used are constantly changing and innovating. For solar power to be widely accepted and used, the following technical problems must be solved:

1. The first question is whether the conversion efficiency of solar panels can be greatly improved. For example, the conversion efficiency of large-scale solar panels will be increased from about 18% now to about 30% when the cost is guaranteed to be reduced.

2. Solve the security problem of supply network under the impact and shock of photovoltaic power generation on large power grid. Otherwise, the large grid cannot withstand the impact of high proportion of solar photovoltaic power generation.

3. Substantially reduce the cost of solar power generation equipment, so that the cost per kilowatt is 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 pv system is about 10,000 yuan per kilowatt. At the same time, the annual effective time of conventional thermal power generation is more than 6000 hours, while that of solar photovoltaic system is only 2,000 hours.

From the above analysis, we can see that the future of solar power generation is bright in the long run. If the problem of photovoltaic technology cannot be improved, it will become one of the factors restricting the development of solar power generation.
