Quick Answer
Short Answer: Acceptance of solar varies greatly by region, influenced by factors such as climate, energy policies, and cultural attitudes towards renewable energy. In areas with abundant sunlight, like California and Arizona, solar adoption is high, while in regions with limited sun hours, like the Northeast and Northwest, adoption rates are lower. This disparity is also reflected in the number of solar installations per capita.
Regional Variations in Solar Adoption
The number of solar installations per capita varies significantly across the United States. According to the Solar Energy Industries Association (SEIA), the top five states for solar installations per capita in 2020 were Hawaii, New Mexico, California, Vermont, and Colorado. These states have an average of 3.5 to 5.5 solar installations per 100 residents, compared to the national average of 1.8 installations per 100 residents. Factors such as high electricity prices, favorable net metering policies, and incentives drive the high adoption rates in these regions.
Sun Hours and Solar Potential
Sun hours, or the amount of solar irradiance per day, play a significant role in determining a region’s solar potential. California, for example, has an average of 7.3 sun hours per day, while states in the Northeast and Northwest average 2-4 sun hours per day. This disparity affects the efficiency and payback period of solar systems in different regions. For instance, a solar system in California can produce up to 30% more electricity than one in the Northeast, assuming the same system size and efficiency.
