You’re hearing the terms ‘KW’ and ‘KWH’ regularly tossed around. So what do they mean, and how do they relate to your energy bill? Try thinking about it like this:
KW —> Energy Demand
KWH —> Energy Consumption
KW measures energy usage at a given moment, while KWH measures energy usage over a given time. Check out this great car analogy to better understand how this works.
How Does This Difference Affect Your Utility Bill?
Utilities employ what are called ‘Demand Charges’. Picture this: You and Bob both use 1,000 KWH in February. You used an average of 34 KWH per day, but Bob used 200 KWH in just one day! Bob’s bill at the end of the month will be significantly higher than yours because of the greater demand placed on the grid during that certain day.
How Does This Affect My Solar System?
When designing a solar system, its size (KW) is determined by both your annual consumption (KWH), and by the amount of energy your solar panels can produce.
