Measuring the power produced by a solar panel

Anyway, as a little project I''m interested in measuring how much power my solar panel is producing at any point in time (then being able to graph it etc with some software). My solar panel is rated at 20w and has a fixed current of 1 amp thus as the panel is more or less in sunlight it generates a value between 0-20V.

Measuring the Power of a Solar Panel

We said previously that the output power of a solar panel mainly depends on the electrical load connected to it. This load can vary from an infinite resistance, (∞Ω) to a zero resistance, (0Ω) value thus producing an open-circuit voltage, V OC at one end and a short-circuit current, I SC respectively, at the other. Then we need to be able to find an external resistive value
