Watts: The amount of energy a light bulb uses. The lower the light bulb wattage, the lower the electric bill. Compact fluorescent lights (CFLs) and LEDs have a lower wattage than incandescent bulbs but emit the same light output.

How do I calculate wattage?

The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second. For example, a 60-watt light bulb uses 60 joules per second.

Is 100W a lot of power?

A 100 watt panel that receives 8 hours of sunlight per day will produce almost 1 kilowatt-hours per day. If we multiply this by 365 days per year, we get a solar output of about 365 kilowatt-hours annually.
