also time of use menu behave differently if you set battery as % vs Volt

[PKTUN]

am sorry i've been away from holy land of pure for sometime. couldn't track and get update about current state of 'scamming mindset' of our con artist traders. may be @mgalaxy3 @AkbarGr8 @AbbasJin offer more insight

[chdemon]

i did that, but if i do this, then wapda is never being used, even when there is no solar. this is strange problem which is happening and there support also dont know about this.

[chdemon]

no, time of use is something else and does almost exactly same about using wapda means it does not use wapda at all if i uncheck this time of use in setting. i am waiting for there technical director's answer.

[AkbarGr8]

This is so difficult- ie buying genuine panels. My solar vendor allowed me to pickup mine direct from a warehouse/ direct importer so that removed a lot of doubts.

Secondly i bought a complete / sealed pallet with documentation that i verified from the manufacturers website. Attaching pictures as an example.

Who's your vendor? What's his current rate/watt for pallet?

[AkbarGr8]

Mudassir- 03004348817. Was saying 117/watt as of yesterday here in khi but don't know if that holds true after today's usd price hike.

[umans]

I am confused about your requirement. You said you dont want to charge battery with grid, thats doable as explained above.

[chdemon]

brother, i dont want to charge batteries from wapda. but problem is no matter which setting i do from inverter. either it stops using wapda at all. or it keeps charging from wapda. i shared this issue with there technical staff. they asked to wait as they could not find reason why inverter is doing this.

I heard one of the solar installers in KHI on YouTube saying current prices are unnecessarily jacked up and are a result of different traders reselling the same stock to each other over several months and now not many customers want to pay such high prices. Their claim is actual prices will come down to 80-90rs per watt in a while. How true do you guys think this is?

[noobie]

Seems unlikely but i hope it does happen. Want to expand from 10kw to 15kw and 85 to 90/watt would be amazing.

[AkbarGr8]

I saw the same video. Be it cars or solar panels - i haven't seen such substantial drops.

It all boils down to the political situation / if we get the IMF bailout package or not.

If you feel an IMF deal isn't happening- then the best time to buy is now. With political instability/ lack of $ inflows these rates will go up further, even though no body will be buying this equipment as it will be too out of reach.

In Karachi, there are massive delays in net meter installations- so the more one waits, the overall timeline will keep getting pushed forward.

On a side note, I've been reading that load shedding will be the worst that we've encountered this summer. To all those that can afford, they will pay exorbitant prices to get hold of solar panels / hybrid inverters to get through the summer.

[capsat]

if we look at the exchange rate and the importers' hue & cry we may not see drop below Rs.100 in times ahead.

under prevailing circumstances and the electric tariff review by NEPRA , put forth every month by producers, Load shedding schedules will be of short duration but UNIT PRICE will be no less then Rs. 38 + tax & as high as Rs. 46 + tax for domestic consumers. Power consumers with 5kW or above mentioned as connected load unit slab charges vary to peak & off peak charge as well.

[AbbasJin]

UI calculated my July and august bills last year and even then the units averaged out to 43-44rs per unit if you do a simple total bill/total units after including all taxes surcharges etc etc

So this year it’ll probably touch 48-50rs per unit when unit prices are jacked up./. This is for a 3 phase iesco bill ranging from 700-1100 units monthly

[abart]

set battery as % not voltage,
discharge your battery at peak hours like 15% it will stay 85% all the night .
change 85% to 100 percent at around 11am to 12pm, this is you are going to charge your batteries with solar only.

[AbbasJin]

Guys, I've recieved 130/watt rate for longi and Canadian solar 550w panels. And 359000rs for inverex nitrox 3kw inverter?

Are these prices too high or good enough?

[capsat]

@AbbasJin these are very reasonable prices transfer some advance and book the units within validity of quotation.

[noobie]

Hi, I'm interested in knowing the efficiency you guys are getting from your installed solar panels capacity.. I haven't been able to test mine yet since net metering isn't up and running. Do you get around 80% of the capacity? Is that realistic? I've got 10kw panels installed and I'm hoping to get about 8kw (is that realistic?) of power from them. I'm planning on bumping that up to 15k panels soon since I've already got a 12kw inverter. Would i be able to generate the full 12kw on a sunny day with the extra panels?

Thanks!

[noobie]

Also, My solar vendor received a demand notice from Wapda/LESCO for my net metering application (they have paid it now) but LESCO hasn't come for inspection yet. Do you guys have any idea how much time it will take to get the green meter now?My application was submitted approximately 20 days ago.
