“How can we measure direct sunlight irradiance?”
One of the most important things for an area’s solar energy potential is the amount of direct solar irradiance. However, how can we measure this? Well, let’s use our engineering mindset to solve this. First, let’s make a portable apparatus. Then, let’s put a window in this device such that sunlight can be collected. Let’s then focus this slight onto a thermopile, and convert the heat generated into an electrical signal which can describe the power incident on the panel. This machine is known as a pyrheliometer and is vital for measuring solar energy.
