u said it produces 1350 units, saving is 35K
now u said the diff is 662 units, saving is 9K
which one of yours statement is true?

Plz justify 35k, then i am also interested in bigger system. If return of investment is within 2,3 years then i need 20+ 20 kw in my 2 setups. I can invest 10 millions on this project.

Suppose return of 10 million in 4 years, and saving for next 12, 13 years, nice project.

What more justification do you want Sir? I have provided the calculations, I have provided the bill of the client. According to the bill, he has saved 54K somehow but I am not even considering that. 6Kw system can produce around 1080 units (Just considering effective sun hours) which means you will be saving 22K/Month at least. and 40Kw system wont require an investment of 10Mil, It'll cost you around 8.4Mil, and according to my calculation, you will be producing 87,600 units a year, making your payback count of 4.8 Years (considering only Wapda Cost, not including any generator cost here. Also considering unit price to be constant, which it never is).

Take a deep breath and calculate it again. Units in july 2014 were 1097 while units in july 2015 are 435. Difference= 662Units. Now you must consider that he used to run Ac only at night before, however now he runs it throughout the day (On Solar) and also at all night, which means it never switches off. The result is nonetheless in front of you. If you still have doubts then you can further ask questions. I have even offered you guys to give you the client's contact information, lets see where that leads.

@ Pantera

what capacity AC is Mr. Zubair running on 3Kw infini

@ Pantera

what capacity AC is Mr. Zubair running on 3Kw infini

He is running (1) 2.5 Ton Inverter Ac (Mitsubishi) and (1) 1 Ton inverter Ac (Gree) on total 6Kw infini.

I'm using infini 6.4kW
With 2 3KW inverters
Saves me an avg of 28 units daily

electricity tariff massively increased plus calculation method also drastically changed for KARACHI by KE.

@ Pantera

2.5 ton infini AC on infini. :-# Infini can give 13 Amp AC. what amp does this AC consume while compressor is running.
(Correct me if Im wrong)
can we connect two Infini inverters in parallel.

[muh_farooq]

@huzaifa.haroon
This is what i am saying
28*18*30=15,120 per month

Any thing greater than 20,000 is false, may be i am wrong

[muh_farooq]

My 3 kw system gives me 12 units a day, at an average.

[muh_farooq]

@pantera
U are saying that 6kw system can produce 1080 units and can save 22k.
Again u are saying he saved 54k.
Then u are saying he saved 35k.
Which statement is true?

No, both infinis are standalone systems. And his Ac takes 10.5 Amps at peak and runs at 4-5 Amps so it runs fine.

Bro my queries?

[pantera]

@pantera
Bro my queries?

I said according to his bill he saved 54k, words mustnt be twisted. And everything is illustrated on the bill for you to see. On average he has saved around 35k monthly during the summer.

[pantera]

@pantera
Bro my queries?

And I am not just talking in calculation, theory is different than reality. He saved 1080 units, but what about the extra units he used at night now which he wouldnt otherwise? I am talking about changes in real term here.

[huzaifa.haroon]

No offense to anyone and i don't want to get into fight.
I am using infini with yingli solar panels and even i change angles of panels season to season but still the max output they give Is when there is a little solar and weather is not very hot.
I same 28 units on avg without Ac.
My electricity bill has reduced from 24k to 16-18k
Not much of a difference but i don't care to much about that because i installed it to make my home load shedding free.
So, you can't save 35k monthly.

In case of liquid go for AGS 165 Ah X 2 ...... in dry NARADA 100 Ah X 2 ..........
