sorry

sorry my fault. I must go to primary school again!!!

for 48V 300Ah battery lowest price is about R35K which is no so bad at all.

thanks.

@Weasel I see you are online and hope you will give the quick answer then Chinese co.. I made an enquiry for the same cells you already bought, so while I am waiting for the price from Chinese , how much did they charged you for them ? regards

Do you switch off the batteries too? If not it doesn't have much of effect

@TTT I am afraid we won't see that in our lifetimes

https://www.businessinsider.co.za/draft-rules-require-solar-pv-backup-generators-to-be-registered-2018-5 ANC wants to charge us for using the sun and the wind. I wander when they will start charging us for the air we breathe !

the cup is for your granny!

Update of my multi strings 7:20 12+3 panels 98.2V 578w 12 panels 89.1v 262w 12:00 12+3 panels 84v 1986w 12 panels 74v 2108w 16;00 12+3 panels 79v 1007w 12 panels 85v 636w

@SolarNoob thanks for the chart. I am even more encouraged with your and Plonkster's charts and Chris's post to go that way. Thanks to all of you.

Yes @plonkster it does illustrate well. Hope the east facing panels does the same but in opposite direction. Thanks for the charts.

Do you have a knowledge of how much longer it is or what are the "working hours " these days?

Wow, how do they perform ?

I will continue as soon as weather clears

I am sorry for the joke, I did not know about your wife. My reason to reply to the post starter's question was to tell that there is no issue with multi orientation of panels. At least I do not have any problem. My aim was to see how much power I can count on putting whole Array to face east and another to face west cause I am lacking power in the early morning and in the late afternoon. My first idea was to build a solar tracker which is extremely simple to do but decided to erect a new roof on the part of the house where is a flat roof now and where all the panels are installed . The new one will face east-west with enough space to accommodate 12+12 panels.

That's what the slaves are for, aren't they?

we simply couldn't stop chatting! As you can see @Chris Hobson is still slipping. It was very interesting subject we were discussing.

Now at 7:00 15 panels array is producing 572w at 101.9v 12 panels array is producing 209w at 83v 12:00 15 panels array is producing 2209w at 84v 12 panels array is producing 2371w at 74v I will edit this post at and at 15:30

@Chris Hobson Yes I have 3 Axperts. All of them has 12x 250W arrays plus to one of them I added 3 same type of panels that faces east.

I am not sure I understand you. If I leave only three east facing panels running I can compare to 12 panels of another array and see how east facing panels are efficient. Do you agree with that or not?

I will then disconnect 12 tomorrow morning and leave 3 east facing panels running and tell you the voltage of both of them. You must take in account the weather that was very cloudy whole day today but forecast for tomorrow morning is party cloudy so we might have a chance to see better reading . 'how much do the three influence voltages when the system is up and running. '' I can tell you the power the three produce in the morning is at lease double if not more then the other 12. I was not paying to much attention on the voltage as I did to the power produced by the three.

No, it is not but difference come from 3 panels only against other 12 which are in the shade at the time I took the voltage. I will post the afternoon voltage

@Chris Hobson here are the voltages : 15 panels 95v 12 panels 85v
