Since the sun transits once a day, energy per 24 hours is relatively
meaningful in my view. In fact more relevant than dividing by 24 h to get an
average. It doesn't arrive on anything like an "average" basis and storage is
required to get continuous power. You can certainly calculate an average
power, and I know you know how to. The question is should you.

Megajoules? Since when is the joule/area a unit in radiation? Radiation is
energy-flow thus power. Average insolation in the US is usually considered of
200 W/m2 if my memory serves me right. So Seattle might be 100 W/m2, or maybe
50 W/m2. Stan J

A better reference might be a clear, sunny day at the same latitude, on the
same date. I estimate around 14 MJ depending on exact assumptions.
What would one "convert" it to? British Thermal Units per square yard? Horses
per acre?

That's great but wouldn't it be better if there were some reference points
like how much solar energy other cities receive. The best way to make metric
work is to make it relevant in every day life. If people want to understand km,
learn the distances between cities, kg--the weight (mass) of common objects,
etc.

Foxnews published this article about the total insolation in Seattle
last Friday amounting to only 0.37 MJ/m² (though they spelled out the
unit names). No "translation"! I posted a supportive comment.
