How to scan a solar panel's IV curve and other fundamentals of solar

In this video we go over the building block of PV systems which is the PV generator. We begin by introducing the basic electrical model for a PV cell which we then use to derive the operating behaviour of any kind of PV generator. The concepts are demonstrated with experiments that you can perform at your own convenience. Here is a list of the video's topics: 1:20 Single Mechanism Three Parameter Model for a solar cell 3:06 The IV curve 4:50 Combining generators, or when solar generators act as voltage or current sources 6:10 What is a PV generator exactly? 6:39 The split cell module 10:15 Current and voltage mismatch in series strings 10:59 Current and voltage mismatch in parallel outputs 13:27 Shading experiments 20:05 Standard conditions 21:04 Efficiency of a PV generator 23:50 PV Efficiency and light intensity 26:32 PV loading 31:51 PV loading experiment where we scan an IV curve with a motor 32:17 What is a solar panel's efficiency under very low light conditions, like say, a twentieth of what they are at Standard conditions? Is it the same? Let's see how much it deteriorates. 38:12 We compare two modules to check some of the assumptions we have made during the video. We compare two solar panels with two very different efficiencies and configuration. The LG Neon R is a 60-cell module made up of high efficiency cells, and the Canadian Solar 365W is a split 72 cell module that's 14% larger. Despite them being very different they are kind of the same through the lens of some peculiar ratios.
