What factors determine a solar PV power plant's capacity factor?
A solar PV power plant's capacity factor is largely determined by three main factors: resource quality, tracking capabilities, and inverter-sizing considerations. Sunnier locations, such as those in the southwestern United States, have more hours of direct, high-angle sunlight per year, allowing the solar PV modules to capture more sunlight.
How much solar power does California have?
Solar power capacity is steadily expanding throughout the United States, as more than half of the states now boast 1 gigawatt (GW) or greater of installed solar. California has set an ambitious goal of achieving 100% clean energy by 2045. The state has been at the forefront of renewable energy generation and solar power generation in particular.
What is the average solar PV capacity factor?
Earlier I noted that the average solar PV capacity factor of approximately 18% at 1MW is also broadly comparable to the 16% estimate in my previous post, which was based dominantly on plants less than one MW in size. Figure 4 superimposes the capacity factors from the previous post on the EIA data out to 10MW.
How much solar power does Massachusetts have?
Small-scale solar PV systems made up nearly 66% of the state's total solar capacity that year. On the other hand, more than 190 MW of capacity have been added from utility-scale facilities since January 2021. In July 2023, Massachusetts was ranked as the tenth state in net solar PV power generation.
What is a good solar capacity factor?
These four sources have an overall capacity factor of (27.5+18.4+17.5+15.1)/4 = 19.6%. Twenty percent would therefore be a good round number for planning purposes, always assuming that US solar subsidies are maintained at the levels necessary to support further PV expansion.
What percentage of State Electricity is generated by solar energy?
In 2022, solar energy contributed 19% of the state's utility-scale electricity net generation. When adding small-scale generation, solar energy accounted for 27% of the state's total electricity generation. The solar industry employs more than 78,000 throughout the state.
