Difference Between kW and kWh


Understanding the basics of energy and power can be confusing, especially when it comes to terms like kW (kilowatt) and kWh (kilowatt-hour). If you’re considering solar panel installation, knowing the difference between these two terms is crucial for making informed decisions about your energy consumption and savings. Let’s break down the difference between kW and kWh in simple terms to help you understand how they relate to your home or business’s solar energy system.

What is a Kilowatt (kW)?

A kilowatt (kW) is a unit of power that measures how fast energy is used or produced. Think of it as the “rate” at which electricity flows to your appliances.

1 kW = 1,000 watts

For example, if you have a 1 kW solar panel system, it can produce 1,000 watts of power at any given moment when the sun is shining.

Common Examples of Power Usage in kW

1. A standard air conditioner might use around 2-5 kW of power.

2. A washing machine typically uses about 0.5-2 kW while in operation.

3. A microwave could use about 1 kW of power.
