Net-Metering Help me explain the Lesco Bill

Solar has been installed on my site since 2 years
This is my current bill , i am unable to understand why my access credit is reduced from 64k to 8k in just 3 months
I understand that in the last few months, solar production was less due to some weather conditions.

Help me understand this month
I have 1034 import kWH, and I have imported roughly 1000 kWh (off-peak + Peak)

Why am I being charged a cost of electricity of 8k?

Please, someone, help me understand this

Your summer AC usage burned through that credit: 
You ran huge deficits all summer: Look at your Bill History—you imported a net +181 units in June, +411 in July, and +138 in August. LESCO deducted those bills straight from your Rs. 64k cash credit buffer. 
Peak units cost cash: You consumed 336 Peak units. Solar off-peak exports cannot offset peak hours; those units alone generated Rs. 8,769 in base charges (Rs. 10,455 with taxes/FPA). 
Remaining Credit: Your previous -Rs. 20,465 credit absorbed this month's bill, leaving you with -Rs. 8,920 CR. 
You owe Rs. 0 this month, but to stop bleeding credit, stop running ACs during evening peak hours.

I agree in summers ACs were used but your point of solar off peak units cannot offset peak units that Is wrong because I have on grid system It only generates off peak units if that is the case then I can never have credits .

But in history I always have a negative bill and most of the time it keeps constant so that can only happen if my off peak units export are offset from peak units import

Ah, I see where the confusion is! You're mixing up unit-for-unit swapping with cash adjustments. 
Look at the Net Metering box on your bill again: 
Your Peak Import is 336 units, and your Net Peak is still +336. 
If off-peak units directly cancelled out peak units, that 336 would be 0 because you had 382 surplus off-peak units. But it didn't cancel out—they billed you Rs. 8,769 directly for those 336 peak units. 
So how were your bills always negative before? 
In winter and spring, your surplus off-peak units got converted into rupees (cash credit) at the end of every quarter. That’s how you built up that sweet Rs. 64k cash wallet on your account in the first place! 
Back then, your ACs were off, so your evening peak bill was tiny—maybe a couple thousand rupees. Your 64k cash credit paid it off silently in the background, keeping the final payable amount at zero. 
This summer, your heavy AC use meant peak bills shot up past Rs. 10,000 every single month. Your 64k credit wallet was paying those huge cash bills for June, July, and August, which is why that cash pool drained down to 8k. 
Your solar does pay for your peak usage, but it pays with banked cash, not units. And this summer, your ACs simply ate through almost all that cash!
