The home photovoltaic market is maturing and industry standards are on the horizon

Media reporters learned from the 2018 household photovoltaic standard seminar held in Changzhou on May 9 and 10 that the household photovoltaic market is becoming more and more mature, and industry standards are about to emerge
.

In recent years, China's photovoltaic development has been rapid
.
From million-megawatt-level centralized photovoltaic power plants to Trina Solar's "million roof" plan, photovoltaics have moved from high-end industries to thousands of households
.

2017 is the first year of China's distributed photovoltaic development, distributed photovoltaic new installed capacity of 19.
44GW, a year-on-year increase of 3.
7 times, accounting for 36.
6%
of the total new installed capacity.
By the end of last year, the cumulative number of distributed photovoltaic power plants reached 29.
66GW
.
In the first quarter of 2018, the overall development situation of the photovoltaic power generation market was good, with 9.
65GW of new installed capacity of photovoltaics, a year-on-year increase of 22%, of which distributed photovoltaics were 7.
685GW, a year-on-year increase of 217%.

The new installed capacity of distributed photovoltaic is 4 times that of centralized power stations, and household photovoltaic is the main mode
of distributed photovoltaic.
Trina Solar Chairman Gao Jifan calculated an account: "From a macro perspective, the annual power generation potential of China's rooftop photovoltaics is 1.
5 trillion kWh
.
China's electricity consumption in 2017 was 6.
6 trillion kWh, and rooftop power can meet nearly a quarter of its electricity demand
.
"Jiangsu Province, as China's largest province with installed photovoltaic capacity, has installed 75,000 household photovoltaic households
.

Distributed photovoltaics have been highly valued by the state, and the subsidies are timely and high
.
This year, the state will subsidize 0.
37 yuan per kWh for distributed photovoltaic power generation projects in the mode of "spontaneous self-consumption and surplus grid"; 0.
42 yuan per kWh for village-level photovoltaic poverty alleviation power stations with benchmark electricity prices and household distributed photovoltaic poverty alleviation projects of 0.
5 MW and below
.
The quality of household photovoltaic has become a hot spot, and household photovoltaic standards need to be introduced
urgently.
