# Re: [Phys-L] [SPAM] Re: solar constant

A very quick search on trusty google showed up two experiments that may be worth the effort.

You have inspired me to give both of the above a try to see what sort of results they yeild.

Thanks! Can you send me that article, or is there a web link?

The solar constant is around 1370 W/m2. I believe this is the average
value over the entire Earth in one year. I have two questions.

1. How can I find the approximate value on a given day at a given location
(latitude)? Is there some formula or way to estimate? I realize this might
not be easy.

2. Is there a "simple" experiment kids can do to measure the solar
constant (solar cell, heating water, etc.)?

This has some good concepts for energy, heat, and optics in both physics
and astronomy.

Long ago we developed a simple experiment to measure the solar constant:
