Well, Let me share with you my own experience. I have seen most of the people using solar panels to charge the UPS batteries. The issue with this model is that it can only save your electricity bill and gives limited time backup. A UPS with good battery/batteries can give you 2-4 hours backup. It works fine with scheduled load shedding i.e. 1 hr power outage after each 2 hrs or even on alternate hours, which is not the case in most of the areas in Pakistan specially in summer.

To get independent of WAPDA (at least for fans and lights) I went for 12V fans and lights. I have made simple setup diagram (attachment 1). The main advantage with this setup is that it gives more backup (24Hrs in my case with two fans) as compared to the UPS system which can go upto 4hrs.

The diagram shows panel connected to a 'solar power controller', battery and 12v fan. The only thing you may not be aware of is the power controller; it is a small device (2.5''x4''x0.75'') that is used to avoid battery overcharging. Further it shows the battery status and avoid using batteries at day time. see attachment 2

Cost of the setup depends on the quality and capacity of the solar panel and battery you purchase. Approximate prices are as below:

Solar panel : 60 to 150 Rs. per Watt. 150Watt panel costs from 8500 to 20000+.

Solar power Controller: PKR 1000 to 2000

12v Pedestal Fan(with led light): PKR 2500 to 3500

Battery: you all may know well :)... 200Ah battery works fine with 150W panel

Backup: 200Ah can run 2 pedestal fans and light for the whole night.

Availability : I bought all the stuff from Hayatabad Karkhano Market, Peshawar, but knowing all these specifications I guess you can find it anywhere.

The whole setup (panel+2fans+controller+200Ah battery) would cost from PKR 30 to 40k which is same as that of UPS.

The issue with this setup would be that you need to run a cable(like UPS).

Deploy solar and sleep well..

I would also like to take the liberty to comment on this important topic as Solar Energy attracts me a lot and I did some basic research about its domestic use - though I am not a scientist

As far as my understanding is concerned, the big stumbling block to bring solar into common life is the storage issues - as the use of batteries does not only make it costly but also a bit hassle-some

I am aware of 'reverse metering' or other on-grid concepts - but these things are out of DIY scope and might not be available in Pakistan soon (I wish it comes asap)

so can anyone share their thoughts on how one can make solar viable for urban life? especially keeping in view Pakistani dynamics?

At home if you have the required equipment and some basic knowledge, you can make a cell in working condition but the equipment it self and the assembling process is a little bit difficult. I have read this book in chunks and another DIY book and video, the process seems to be easy but the dealers, arranging solar cells get the most out of you.

Dear Asalam-o-Aliekum

it is requested to all group members that can any ONE share here the complete method with all material detail for making solar cells for solar panel at home... share knowledge and benefit more peoples in Pakistan to promote Green Energy Awareness Campaign.

I would welcome all experienced people for sharing easy and complete step by step method for making solar cell at HOME.
