"Self-sufficiency does not mean 'going back' to the acceptance of a lower standard of living. On the contrary, it is the striving for a higher standard of living, for food that is organically grown and good, for the good life in pleasant surroundings... and for the satisfaction that comes from doing difficult and intricate jobs well and successfully." John Seymour ~ Self Sufficiency 2003

"Sunshine on my shoulders makes me happy..."

I found this link on a blog last year - sorry, I was so enthralled, that I forgot to make a note which blog is was.  But, how cool is this site: http://www.sunearthtools.com/dp/tools/pos_sun.php?lang=en

But, with our solar panels / solar power in mind, I took a reading of the sun rays then, and thought I'd do another reading today.

What a difference a couple of months makes!
14 January 2014
The sun rises 1 3/4 hours earlier, and sets and sets 23 minutes later.  So, we're gaining roughly 2 1/4 hours more sun - and more direct sun - in summer than in winter.

You can also see exactly why they recommend facing PV panels due north in the Southern Hemisphere and due south in the Northern hemisphere.  Facing them due north allows for more of the sun's rays to hit the solar panels during the shorter, colder winter months.  And, strangely enough, the rays are more centered on the PV panerls during winter - during summer they rise and set "behind" the panels.

For those in the northern hemisphere, hit the link and check out the difference between now (mid-winter) and a few months time (mid-summer) where you live :)

Update: the blog where I was first introduced to sunearthtools is http://comptonia.blogspot.com/2013/09/post-equinoctal-thoughts.html

  1. Have you ever heard of Cody Lundin? He's a survivalist who lives in Arizona. He is very much into passive solar heating and other related things. Lundin is the fellow who costarred on "Dual Survival". He's written two books, both of which were pretty good. I don't know if they have them in South Africa, though.

Thank you for taking the time to comment - it makes my day and removes the "loneliness' of sitting at my screen blogging supposedly to myself ;)
