![]() ![]() ![]() If we multiply the kilowatts and time, we get the amount of energy we used. The power goes out in the neighborhood and we resort to solar power for 3 hours. Let’s say we have a solar system that’s rated at 2 kW and is fitted with an EP500 Bluetti Power Station. What separates one from the other is including time as a variable. Kilowatts and kilowatt-hours are easy to confuse given their similar names. If we can think of kilowatts and watts as power, a watt hour or kilowatt hour can be described as energy.Įnergy is the power that’s used or produced over a given period. This is why kWh calculators are so important as they allow us to size our solar systems using power measured in kW. ![]() When we take a graph detailing the output per hour in a day, we’ll see that it only reaches the peak at around midday. The ‘6 kW’ marker means the system outputs that much power at any point on a perfectly sunny day. Let’s take a 6 kW solar system made up of 24, 250 W solar panels. Well, solar systems are sized in watts with the larger systems being measured in kilowatts. So what does this have to do with the world of solar? This means we can use watt or kW to amp conversions if we have the necessary values. Using Ohm’s or Watt’s Law, we can work out the voltage, current, watts, and resistance of a system. This law states that the power or wattage of a circuit is equivalent to the product of the current and voltage running through it. Watts can be calculated or determined using Watt’s Law. They typically describe the rate at which work is done on an object.Ī single watt is equivalent to one joule of work being done on an object. When we speak about watts, we’re talking about a metric unit measuring power. ![]()
