Estimation of solar radiation from the number of sunshine hours, Applied Energy, 63,161–167 Angstrom A., 1924. Solar and terrestrial radiation, Quarterly Journal of Royal Meteorological Society, 50, 121–125 Bakirci, K. 2009. Correlations for estimation of daily global solar radiation with hours of bright sunshine in Turkey, Energy, 34, 485-501.
Since the peak solar radiation is 1 kW/m 2, the number of peak sun hours is numerically identical to the average daily solar insolation. For example, a location that receives 8 kWh/m 2 per day can be said to have received 8 hours of sun per day at 1 kW/m 2.
To asses the availability of solar radiation at different locations, measurements of global radiation, diffuse radiation, beam radiation, sun shine hours, bright sun shine hours, maximum and minimum temperature, humidity, pressure, visibility, wind speed and direction, gust speed, water precipitation, and air mass are very important parameters.
Accurate and efficient estimation of surface solar radiation facilitates the planning and design of photovoltaic energy systems. Most surface solar radiation studies have focused on developing high-accuracy models, while overlooking model uncertainty, generalizability, computational efficiency, and interpretability.
The solar resource varies with the geographic location, time, season, weather, and the landscape. Its utilization involves capturing solar radiation, its conversion, and storage. Assessment of solar resources at a location is vital for knowing the potential for utilization.
The average daily solar insolation in units of kWh/m 2 per day is sometimes referred to as "peak sun hours". The term "peak sun hours" refers to the solar insolation which a particular location would receive if the sun were shining at its maximum value for a certain number of hours.
