The suns rays change each day for solar panels
Permalink  

Being in Sa I have noticed the sun does not deliver the same amount of amps each day for solar panels?

Today I been getting only  16.5 amps per hour,but 3 days ago I was pumping in 32 amps a hour from my panels, and I have been in the same position for 2 weeks now?

How many watts are your solar panels. I have 200 watts and get around 9 amps/hour..

The days get shorter as we move closer to the winter solstice(shortest day of the year around june 21) then they start to get longer again.

On my home solar, rated at 3.9kw I have had 5.4kw delivered from panels.

I monitored output in a log for 6 months or so and found on days with light white whispy clouds (say that fast) output is increased when compared to clear blue sky.

Obviously refraction of light will have a beneficial effect.

Maybe panels need a wash C/Man.

 

EDIT: Obvious also my panels are under rated by manufacturer,,, though I'd better admit that.

 I have 3 x 200 watt here, but today is overcast again so it be run the genny all day as I be lucky to get maybe 7 or 9 amps a hour.

Yesterday I made 96.8 amps, but 3 days ago I was pumping in over 30 amps think I made 156 amps into my 2 x 280 amp batteries

We found a difference in the amount of amps we got when over east (we are based in WA) and here in WA... the panels do much better in WA than say SA or Vic or NSW... Queensland is not so bad but we have not gone to NT yet.... WA seems to be the best place for sun even when cloudy. We will be putting up a few more panels now before we go back over east again :)
EG a cloudy over there we might get 1 or 2 amps over here we would get get between 9 and 15amps.....

 Next time you go throught Port Augusta might be worthwhile going on the steam train from Port Augusta to uorn,its steam during winter and diesel in summer.

solar panels dcrease in output the hotter they get, hence better charge on cloudy days
