PROF'S POSER - Dial 'S' for 'Sun'
Nothing like tapping into the best brains out there.
Sp sorry if this is another question without an answer, as yet.
This weekend I bought a solar security lamp combo.
Where it was needed rather determined where it went and, despite a 5m cable, my choices were limited.
However, I did manage, a great risk to life and limb, to get it pretty high up, to make the most of the daytime sunlight. And, despite the picture, the panel is pretty much clear exposure all day.
However, I faced it due South. And near vertical. Now I have noticed, on a nice day like today, it is missing out on any solar impact until mid-morning, though if the sun stays out it will keep it pretty much until dusk.
My question is whether this is the most sensible orientation? Two real issues. When is the sun mostly 'out', and when is it at its most solarific?
I know that data will exist, and can determine the optimum year-round setting, as I don't want to go up there again. Scaaaaareee!
In passing, I will advise that I am working on a self powered device to help panels auto-track the heat of the sun, which I'll share when complete.
