  • ISA: EIA: 4% of U.S. households choose to install residential photovoltaic systems

    According to a survey report on residential energy consumption released by the National Energy Information Administration (EIA) a few days ago, by 2020, about 3.7% of American households have installed rooftop photovoltaic systems.

    Rooftop PV system installations vary by region: the Western United States has the most at 8.9 percent; followed by the Northeast (4.7 percent), the South (1.7 percent), and the Midwest (1.4 percent). Photovoltaic systems installed in commercial buildings are also most prevalent in the western United States at 3.8% followed by the Northeast (2.5%), Midwest (0.8%) and South (0.6%).

    The report notes that the installation of rooftop PV systems on residential and commercial buildings also varies by construction year. Buildings built after 1980 are more likely to have rooftop PV systems. The report shows that 5.7% of households with an annual income of more than $150,000 have installed photovoltaic systems, while only 1.1% of households with an income of less than $20,000 have installed photovoltaic systems.

    The U.S. Energy Information Administration (EIA) notes that government-owned buildings are more likely to have rooftop PV systems than buildings owned by other departments or industries. Building-installed PV systems for public gatherings, education, offices or retail accounted for 61% of all commercial building rooftop PV systems.

    In the next decade, the number of photovoltaic systems installed in every sector in the United States will increase significantly. A study by Princeton University shows that with the implementation of the Cut Inflation Act, the installed photovoltaic system in the United States will grow rapidly, from 10GW installed per year in 2020 to 49GW in 2024. The installed capacity will increase by nearly five times. According to Princeton University, by 2030, more than 100 GW of PV systems will be installed annually in the United States.

    Investments in the U.S. PV industry will reach $321 billion by 2030, nearly double the $177 billion expected under current policy. The bill is expected to generate nearly $3.5 trillion in capital investment in new energy supplies in the U.S. over the next decade, the report said.
    Under the act, U.S. annual energy spending is projected to fall by more than 4 percent through 2030, saving U.S. households, businesses and industry nearly $50 billion annually. This saves American households hundreds of dollars in annual energy costs.
