## 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.

100 watt bulbs are phased out currently (though still available), but only those. 100 watt bulbs are incredibly wasteful, I never used them due to the fact that they convert most of their energy to heat and I live in a warm area, so they not only wasted power in irradiated heat, but power from climate control.
