abdumer;4495909:

The Solar system for residential load is designed according to the following parameters:

Type of appliances ( Inverter ACs, fans, fridges, freezers and Etc ).

Quantity of each appliance

Approximate Operating duration of appliances per day.

In order to make the system cost effective and realistic in terms of initial capital, i would request your to list down your priority load which you wish to run on solar. Shifting all load like microwaves,iron, all ACs, water pumps is not feasible both with design and cost perspective.

Infini inverter can handle 4100 Watts of panels (20 panels for 205 Watt each) Or 3000 Watts of panels (12 panels for 300 Watt each) depending upon the current ratings. Infini with maximum connected panels will generate 350 KWh to 400 KWh approx.

Running all load day and night without WAPDA/GRID is not recommended because this will require a huge battery bank which means it will increase your capital cost as well as your replacement cost.

To make your design effective, i recommend you to please share your Load Profile, which you intend to run on Solar Energy.

I will be able to quote any price after knowing your load details and requirement. And go for installing (Inverter type ACs) for your house as they can easily be run of Solar systems and takes almost half power then conventional Split ACs even when running on WAPDA/GRID

How about if I want a backup to run from 5pm to 10pm in other words how many batteries required for 5 hours backup?

I want to bypass the peak hours time.

To the best of my knowledge a DC to ac conversion loss is about 30%. Please correct me if I'm wrong with this figure.

Based on my calculation a 24v 300ah system will hold 7200w dc. And it can handle up to 5000w ac power. Again please correct me if there's an error in my calculation.

conversion losses are lesser....maybe less than 5% for a good system.

what do you want to run during the bypass hours?

Let me remind you that storing energy in batteries (even lead acid) costs more than the peak electricity hour rates. And this is just storage expense, then you add to it the actual electricity expense and conversion/charger losses.

So UPS/battery is only for backup (when there is no electricity available). Stored electricity in battery costs even more than electricity generated from a diesel generator (a decent branded one).

To find out cost of battery storage, figure out how many total charge cycles the battery can take. From that calculate total energy it will be able to store in its life time. Now take the total cost of battery and divide it by total energy figure.

I'm thinking that 24v 300ah battery pack will cost ~50k. And perhaps last 1000 charge cycles. So total it can store is 7200kw-hr. which assuming the battery costs 50k, makes a storage cost of around rs7/kw-hr. And this figure is probably way off from reality becasue the battery probably costs way more and becaue I know that batteries don't go all the way down to 0 volts. They go from max volts (~12.5 or so) down to about 10.xx something (that's when the UPS shows 0% as below this voltage, the AC volts will be so low, it will not run anything). So for 7200w-hrs you probably need a battery much bigger.

I have calculated a 24v 150ah system lasts about 1:40h with 700 watts load. So I assume I will need 3 or may be 3.5 times bigger system to reach my target.

As told earlier, what you are trying to do will cost you money for nothing. Peak hour rate is rs18/kw-hr. this is cheaper than what it would cost you if you used electricity stored in UPS battery. So using UPS to save yourself from peak rate doesn't make economic sense. Electricity from UPS costs upwards of rs20/kw-hr. I hope you understand now.

I am also planning to buy solar for my home. Plan is to slowly convert everything except air conditioner on solar.

Today I visited Nizam Energy and they gave a quote of Rs 436,100 for 1050 watts load setup.

Canadian Solar Panel 1900w with 10 yrs warranty Rs 209,000
Axpert Inverter 2kva with 1 yr warranty Rs 38,000
Battery 150ah / 12V qty 4 (dry) with 1 yr warranty Rs 114,000
rest like structure, power cables
db box, transportation and installation

Total comes to Rs 436,100 . This is with 3 hours backup on batteries. as per their calculation the load is 6100wh during day and 3350 wh during night on batteries.

This is very expensive. I do not have an electrical background / knowledge, so a full DIY is out.

Any other options in Lahore for solar.

I have install a 1000 watt continues using 24 hours system total load without ac 5 kva expert Soler inverter. 3200 watt mono plates one extra charge controler 60amp 200amp 12 battery bank liquid

I have 10 x 200 watt panels
1 x 3 KVA MPPT
2 x 150AH battery

Connected to serve 2KVA max load

From morning 6 to evening 6 I running all my load on Solar + Battery

All these systems are quite expensive.. can an expert give a cheaper option of charging a 200 amp battery using homeage inverter from sunlight and keeping wapda input off whole day... especially when 4-6nonstop power failure...

To do that you will need a solar panel which will be connected to a charge controller and the charge controller will be connected to the battery. Used panels can be bought for about Rs.50 per watt and a PWM charge controller won't be very expensive.
