Solar radiation in Portsmouth Solar radiation 15 days
In the following list by days you can know the forecast of the predicted solar radiation. To know the data hour by hour, click on the day that interests you. If you have a solar panel system, these data will be useful to predict the energy it will produce.
The unit of measurement for solar radiation is expressed in W/m2 (Watts per square meter).

To carry out the solar radiation forecast, the angle of incidence of solar radiation is taken into account, which depends, among others, on the declination, latitude, inclination and hour angle. The weather forecast is also taken into account, since, for example, on a cloudy day we would only have diffuse radiation, much less than direct radiation.
