A minor correction. The largest percentage of heat from the sun is in the form of visible light. When visible light is absorbed by the earth (not reflected) it heats the earth. The atmospheric greenhouse effect works because greenhouse gasses are transparent to incoming visible light, but the heat it creates is re-radiated as outgoing infra red radiation that is absorbed by greenhouse gasses.
Here's what I've summarized so far:ohm = resistanceamp = level of electric charge (electrons passing a given point/second) or speedwatt = rate of energy conversionvolt = force/power (the level of force/power the conductor is at when it takes 1 amp to create 1 watt) Photons (light particles) from the sun hit a solar panel and interact with silicon to create electrical current. That current level may vary, depending on the number of electrons released by the interaction (would this be measured in watts?). The speed at which the electrons travel along the wire to the battery is measured in amps (thus the expression "amped up"). Direct Current (DC) means the electron current is allowed to flow unimpeded. The electrons are then stuffed into the battery until it reaches a voltage (power level/force) where the battery is considered full (of electrons).Have I got that right?
