First, let's look at the energy consumption of an air conditioning unit itself. Is it all that different from a toaster or a computer? The sheer numbers show that it is. An average american house spends around 10,812 kW a year, according to the U.S. Energy Information. .
Let's move on to a more complicated example. We've decided to install a central air conditioning system in a house somewhere in LA. Its rated wattage is 3,000 W. We'll set 6 hours as an estimated daily work time. This time though, running times of a PV system. .
First, let's think of the most simple situation: an AC unit works only during daytime at the same time as solar panels. Ideally, we would like. .
Imagine a house somewhere in Minnesota. There is a study where it gets really hot during summer days and it's impossible to work there. We install a small AC unit which requires 500W. It works for 6 hours five days a week. Therefore, on paper. [pdf]
