Why has the growth rate of household photovoltaics sharply decreased?
Is the market size of household photovoltaics coming to an end
According to statistics from the National Energy Administration, the newly added grid connected capacity of household photovoltaics in the first three quarters of 2024 was 22.8 million kilowatts, a decrease of 10.177 million kilowatts compared to the same period in 2023. The installed capacity growth rate of centralized and distributed power plants is still increasing, and household photovoltaics is the only type of installed capacity that has experienced a year-on-year decline in growth rate
Household photovoltaic refers to distributed photovoltaic power generation projects built on the roofs of households or residential areas. Centralized power stations refer to those with an installed capacity greater than 6 megawatts, while distributed power stations are less than 6 megawatts. They can be divided into two categories: household and commercial. Household grid connected capacity is the smallest, generally not exceeding 50 kilowatts
Why hasn't the growth of household photovoltaics stopped
Tang Daqian, Deputy Director of Credit Rating Company Fitch Ratings, told Southern Weekly that the main reason is that the rapid growth of household photovoltaic installations has not matched the speed of intelligent upgrading and transformation of the distribution network
The potential large-scale grid connection of household photovoltaics poses a challenge to the safe operation of the distribution network, and the carrying capacity of distributed photovoltaics connected to the grid in pilot provinces is not optimistic. On the one hand, the dispersed layout and diverse operating conditions of distributed photovoltaics have increased the difficulty of local power grid allocation. On the other hand, it is closely related to its surging capacity
