Hence at a northern hemisphere location at latitude j, the highest elevation of the Sun at noon is not constant throughout the year, but is instead hSmax ¼ 90 À j þ d. In the northern hemisphere, d > 0 in summer, but d < 0 during winter. The amount of solar radiation over the course of a given year is primarily determined by latitude j and solar declination d.

67 per kWh for electricity fed into the grid for a period of 12 years, whereby this emolument was spread across the electricity prices paid by all customers. In conjunction with the fixed federal and cantonal subsidies amounting to a few euros per watt of peak power that were available back then, this framework constituted an emolument system that allowed for the depreciation of grid-connected systems during their lifetime. This system also resulted in the realization of a great many such systems during the ensuing years.
Common time intervals are one year (a), one month (mt), one day (d) or one hour (h). Units: kWh/m2 and MJ/m2 (kWh/m2 is more expedient for PV applications). 278 kWh. Pyranometer: Instrument for measuring global radiation (global irradiance G) on a level surface over the whole wavelength range between approx. 3 and 3 mm. Based on the thermoelectric principle, pyranometers are highly accurate but expensive instruments that are mainly used by weather services.
