Winter solstice and solar power

In this society where everything is available to us at the flick of a switch, we become disconnected from the marvels of nature, but since setting up my first solar power rig, I’m starting to identify a little more with paganistic worship ;).

Each day when the sun is shining, it’s not just a case of “hmm, nice day” for me, it’s “hooray, good battery charging day – thank you sun!”.

This year has been particularly interesting for me as where I’m situated is heavily treed. That’s absolutely wonderful, but it also creates a challenge during winter when the sun sits lower in the sky, casting longer shadows. I didn’t want to cut any trees down, so I had to select my camp site carefully, but some of it was guesswork having not been here for a full year.

Today is winter solstice in Australia (summer solstice in the Northern Hemisphere) – it’s the shortest day of the year and the day that the sun is at its lowest angle – about 31.7° above the horizon at solar noon – therefore far less charging time than in summer; when on December 18 it will be at 78.5°.

While the last couple of weeks have seen me having to move the solar panel a little more to dodge shadows and get the most from the available sunlight, it’s been great to find that spot I picked to call “home” will suffice! My generator usage, even though we’ve had a lot of cloud/fog cover in the past week has been minimal.

Just on that point, it’s a mistake that many people new to solar power make when purchasing a system – not taking into account that while there may be available daylight for X hours a day, during winter peak sun hours are X minus Y. In my neck of the woods at this time of the year it’s around 4.5 hours a day.

While I’m not about to don the druid gear and join the gang at StoneHenge, going off-grid certainly does give you a better understanding of why our ancestors were in complete awe of and worshipped the sun!
