150w Solar Panel
How long would a 18W fluorescent tube be lit if a Solar Panel produces 150W?
I don’t understand how much electricity is generated by a solar panel. What does it mean if they say it generates 150W? Is it
per hour or per minute or per second.
If a fluorescent light has a power rating of 18W, does it mean it uses 18W per second, minute or hour? Help!
Watt is a measure of power. 1 Watt is one Joule (a unit of energy) per second.
150 Watt means that you get 150 Joule every second. And 18 Watt implies the fluorescent tube consumes 18 Joule every second.
Therefore a 150 W solar panel would be able to light up 8 (and 1/3, if this means anything…) 18 W fluorescent tubes, as long as it provides that power, that means as long as it is properly lit by the sun.
If you don’t use all the power, you lose it, unless said power is sent to a battery.
