EIA: 4% of American households choose to install household photovoltaic system
According to a recent survey report on residential energy consumption released by the US Energy Information Administration (EIA), by 2020, about 3.7% of US households will have installed roof solar systems.
The installation of roof photovoltaic system varies from region to region: the western region of the United States is the largest, accounting for 8.9%; Next are the Northeast (4.7%), the South (1.7%) and the Midwest (1.4%). PV systems installed in commercial buildings are also the most common in the western United States, reaching 3.8% times in the Northeast (2.5%), Midwest (0.8%) and South (0.6%).
The report points out that the installation of roof photovoltaic systems in residential and commercial buildings also varies according to the year of construction. Buildings built after 1980 are more likely to have rooftop photovoltaic systems installed. The report shows that 5.7% of households with an annual income of more than $150000 have installed photovoltaic systems, while only 1.1% of households with an annual income of less than $20000 have installed photovoltaic systems.
The US Energy Information Administration (EIA) pointed out that buildings owned by government departments are more likely to install roof photovoltaic systems than buildings owned by other departments or industries. Photovoltaic systems installed in buildings for public assembly, education, office or retail account for 61% of all commercial building roof photovoltaic systems.
In the next decade, the number of photovoltaic systems installed by various departments in the United States will increase significantly. A study by Princeton University shows that with the implementation of the Inflation Reduction Act, the installed photovoltaic systems in the United States will grow rapidly, from 10GW installed annually in 2020 to 49GW in 2024, with the installed capacity increasing nearly five times. Princeton University said that by 2030, the annual installed capacity of photovoltaic systems in the United States will exceed 100GW.
By 2030, the investment in the US photovoltaic industry will reach 321 billion US dollars, almost twice the current policy expectation of 177 billion US dollars. According to the report, the bill is expected to bring nearly 3.5 trillion dollars of capital investment to the new energy supply of the United States in the next decade.
According to the bill, by 2030, the annual energy expenditure of the United States is expected to decline by more than 4%, saving nearly $50 billion annually for American households, businesses and industries. This saves American families hundreds of dollars in energy costs every year.
