What is solar rooftop potential?
Solar rooftop potential for the entire country is the number of rooftops that would be suitable for solar power, depending on size, shading, direction, and location. Rooftop potential is not equivalent to the economic or market potential for rooftop solar—it doesn’t consider availability or cost.
Could solar conversion efficiency improve the rooftop potential?
With improvements in solar conversion efficiency, the rooftop potential in the country could be even greater. Residential and other small rooftops represent about 65% of the national rooftop potential, and 42% of residential rooftops are households with low-to-moderate income.
How much solar power will a new roof generate?
NREL estimates that an average of 3.3 million homes per year will be built or will require roof replacement—representing a potential of roughly 30 gigawatts (GW) of solar capacity per year. If even a small fraction of these new roofs had solar installations, it could have a significant impact on U.S. solar power generation.
Should solar panels be installed on a south-facing roof?
Ideally, your solar panels will be installed on a south-facing roof at an angle of about 30°. These are the optimal conditions for solar panel production. The closer you get to this, the more electricity your panels produce. Solar panels with a larger power-to-size ratio will produce more electricity per square foot.
What is rooftop potential?
Rooftop potential is not equivalent to the economic or market potential for rooftop solar—it doesn’t consider availability or cost. Rather, it is the upper limit of solar deployment on rooftops across the country.
Can solar power be installed on a new roof?
If even a small fraction of these new roofs had solar installations, it could have a significant impact on U.S. solar power generation. For individual rooftops, national laboratories and private companies have developed a number of tools to estimate the amount of solar that could be installed on a given rooftop.
