How to Easily Calculate the Conversion of Volts – Amps & Watts
Basic electric theory states that:
Volts are a measure of the force or pressure under which electricity flows.
Amps are a measurement of the current flow rate of electrons.
Watts is a measurement of electrical power created. 1 watt is equal to one joule of energy per second.
In the solar Industry, the ability to easily convert volts, watts and amps is necessary for every part of the business from system sizing to procurement of solar panels, inverters, and balance of system components like connectors and wiring.
My colleague Stewart Wadsworth, an educator from Boots on the Roof treated us to the use of an easy to remember chart to calculate volts, amps and watts.
To use this conversion chart, you will need at least two of the three desired electric values from a specific load requirement. From there, you can calculate the third. Simply draw a triangle, then place a W for watts at the top. Then place a V for volts at one of the bottom corners and an A for amps at the remaining corner.
