The map does indeed show average available solar energy per square meter per day for solar panels tilted at latitude e g if you live in st.

Solar panels hour of light per day map.

Kilowatt hours per square meter. The first 400 watt residential solar panel was released by sunpower in march 2019 but you can now find several panels from different manufacturers that are around this. If the map says 9 kwh m2 then you are getting about 9 full hours of sunlight on the panel. This can also be called solar production potential.

Modern solar panels are around 15 efficient so that works out to approximately 150 watts per square meter or 15 watts per square foot. The maps below illustrate select multiyear annual and monthly average maps and geospatial data from the national solar radiation database nsrdb physical solar model psm. Average solar hours per day. Solar production potential in units of kwh kw yr is the same as saying.

Calculating sun hours per day by zip code how to determine if you get enough sun to make solar panels worth it. Average peak sun hours vary greatly across the country. Instead it refers to an hour in which your solar panels produce a certain amount of energy. The psm covers most of the americas.

A peak sun hour doesn t include just any hour when the sun is out in the sky. A peak sun hour specifically is an hour during which the intensity of sunlight is 1 000 watts per square meter. Africa the middle. Solar panel wattages have steadily increased over time.

Central america south america the caribbean solar insolation map. This is helpful to determine the size of the pv solar array and battery plant needed to operate a solar powered air conditioner for a given number of hours per day. Learn about the nsrdb psm.

The amount of solar radiation or insolation delivered by the sun varies throughout the day based on the sun s position in the sky clouds and other atmospheric conditions. Each kwh m day is consider to be one solar hour. Louis mo you re at 38 627 degrees north so the map assumes the panels are tilted up 38 627 degrees from horizontal. Each peak sun hour is defined as one hour when the intensity of sunlight solar irradiance reaches an average of 1 000 watts of energy per square meter roughly 10 5 feet.

These solar energy maps are visual representations of the amount of energy that a solar photovoltaic system can produce based on the intensity of light that reaches the earth s surface. The earth at sea level receives about 1 000 watts per square meter.
