At present, the PV price policy has been issued in 2019, and other relevant policies are expected to be probable in the second quarter. The demand for domestic PV market is more certain in the second half of the year, and the industry boom continues to increase. In addition, the demand in overseas markets continues to be strong.

The focus of PV parity online is to reduce the on-grid price. For custom solar panel manufacturers, the key is to improve the photoelectric conversion efficiency of photovoltaics. The main methods include:

1. Silicon wafer link: increase the ratio of single crystal.

Single crystal solar cells have higher photoelectric conversion efficiency than polycrystalline batteries, and with the rapid decline in manufacturing costs, it is expected to seize the market share of polycrystalline in the future. Therefore, the growth rate of single crystal silicon wafers will be higher than that of polycrystalline silicon wafers.

2. Solar cell segment: Promote the use of PERC technology.

PERC solar cells increase the absorption of long-wave light by adding back reflectors, while increasing the potential difference between P-N poles, reducing electron recombination and improving photoelectric conversion efficiency. In 2018, China's PERC solar cell accounted for 33.5%. It will reach 50.6% in 2019, and the PERC technology replacement trend is very obvious.

With the approach of photovoltaic level-level Internet access nodes, improving photoelectric conversion efficiency and reducing on-grid tariffs are the development direction of the industry.
