1. Solar Insolation We will be using the term Solar Insolation a lot in this course, and your probably have not used it before. Numerical activity: a) Melbourne has an annual solar irradiation of 1679 kWh/m2/year. Calculate the average Solar Insolation in Wm 2 (averaged over one day and one square meter). Hint: remember kWh is a measure of energy and not power. b) c) A solar panel receives 990 W of solar insolation over 1 day. Calculate the area of the panel if the average solar insolation is 180 Wm³². Australia receives approximately 58 million PJ or radiation per year (1 PJ = 1 x 10¹5 J). Calculate the average Solar Insolation in Wm ². The area of Australia is about 7.7 x 106 km². (Hint: be very careful with converting units) Conceptual activity: In this course we will usually use values for the Solar Insolation defined for a particular location and averaged over 24 hours, and per square meter. Discuss what this means. • Why do we use Solar Insolation per day and per square meter rather than the actual Solar Insolation at a particular time of day? Is Solar Insolation a measure of power or energy? ● 1. Solar Insolation We will be using the term Solar Insolation a lot in this course, and your probably have not used it before.
