Solar plant and Generation

Yes, there is a strong positive correlation between the number of solar plants and total electricity generation across states. With a correlation coefficient of r=0.908, states that have more solar plants consistently tend to generate significantly more electricity overall.

The top two states — California and Arizona — together account for 81.8% of total national solar generation, producing 13,376 GWh out of a national total of 16,358 GWh. A detailed data table has been generated showing the breakdown.

The analysis produced a bar chart and data tables ranking all states by their installed solar capacity in megawatts (MW). The visualization uses a color gradient (yellow to red) to highlight the states with the highest capacity, making it easy to spot the top performers at a glance.

A bar chart has been generated showing the generation-to-installed-capacity ratio (GWh/MW) for each state, ranked from highest to lowest utilization. This ratio indicates how effectively each state converts its installed power capacity into actual electricity generation — higher values mean better utilization.

The analysis ranks each state by how much solar generation (in GWh) is produced per solar plant. A bar chart and data table have been generated showing the full ranking of states by this efficiency metric.

The analysis successfully produced a ranked bar chart and data table showing solar energy generation (in GWh) by state. The visualization displays each state's contribution, color-coded from yellow to red based on generation volume, making it easy to spot the top producers at a glance.

A data table has been generated showing states with high installed capacity but disproportionately low generation output. The table ranks states by their generation-to-capacity ratio (GWh per MW), highlighting those that fall below average efficiency.

Yes, states with larger average plant sizes tend to achieve better generation efficiency. The analysis reveals a strong positive correlation of 0.723 between Average MW Per Plant and Generation per MW of installed capacity, meaning bigger plants generally produce more electricity relative to their capacity.

The bar chart shows how Average MW Per Plant varies across states, with a mean of 12.2 MW. States above this mean favor large-scale solar installations, while those below tend to have smaller distributed plants. The visualization uses a color gradient (yellow to red) to make it easy to spot which states lead in large-scale capacity, with a blue dashed line marking the 12.2 MW average benchmark.

The scatter plot identifies states that fall in the 'Expansion Opportunity Zone' — those with fewer solar plants than the median (≤26.5 plants) but higher average capacity per plant (≥11.6 MW/plant). These states already demonstrate strong plant efficiency, meaning adding more plants there could yield significant capacity growth. The chart uses bubble size to show total installed capacity and color intensity to highlight average MW per plant, making it easy to spot the best candidates in the upper-left quadrant.

Across all states, the national solar energy totals are: 574 solar plants in operation, a combined installed capacity of 6,999 MW, and a total generation of 16,358 GWh.

The analysis calculated the GWh generated per MW of installed capacity for each state. A bar chart has been produced showing how efficiently each state converts its installed capacity into actual generation, along with a data table for detailed reference.

The analysis produced a bar chart and data tables showing solar generation across all states, ranked from lowest to highest. The visualization highlights which states have the least solar generation and lets you compare their installed capacity, number of plants, and average plant size side by side.

A pie chart and data table show each state's share of the total national installed solar capacity. California is by far the largest contributor, holding nearly 63% of the total. Arizona comes in second at 15.4%, followed by North Carolina at 9.56%. The remaining states each hold less than 4% of the national total.

A grouped bar chart has been generated showing the installed capacity rank versus generation rank for each state, sorted by the size of the gap between the two rankings. States appearing on the left side of the chart have the largest discrepancies between how they rank in installed capacity compared to how they rank in actual electricity generation.

Yes, the analysis identified several states with unusually high or low solar metrics that warrant deeper investigation. A z-score heatmap was generated showing how each state compares across four key metrics: number of solar plants, installed capacity (MW), average MW per plant, and generation (GWh). States with z-scores beyond ±1.5 stand out as statistical outliers — meaning their values are significantly above or below the national average. The heatmap uses a red-blue color scale, making it easy to spot which states are extreme in any direction.

The Average MW Per Plant values range from 4.1 to 22.5 MW, with a mean of 12.2 MW and median of 11.6 MW. The analysis reveals two distinct clusters separated by a natural gap of 7.4 MW. Cluster 1 (Low, ≤11.6 MW) includes New York, North Carolina, Colorado, and New Mexico, averaging just 5.6 MW per plant. Cluster 2 (High, 11.6 MW) includes California, Texas, Nevada, and Arizona, averaging 18.8 MW per plant — more than three times higher. Data tables were generated showing the full breakdown by state and cluster.
