Wa Alaikum Salam !
No doubt affordability of Solar Energy Systems for domestic use is an issue, especially due to: 1) capital cost of imported solar panels, heavy duty batteries and imported DC appliances, and 2) maintenance cost of inverters and batteries.
This thread aims to seek attention of local researchers and industries for their contributions in this area for producing cost effective indigenous solar systems/appliances tailored to our local needs.
The consumers, especially those spending more than 20 million rupees in building a house, may also be requested to consider the solar option (may add 5% to the house cost) instead of UPSs and Generators.
The banks may be requested to offer Solar Leasing schemes to help meet the capital costs.
We may optimistically hope that economical Solar Energy Systems would be at our homes within 3 years, Insha'Allah.
Best Regards and Wishes

Asslam-o-Allykum All,I still don't understand the argument about solar energy being affordable. From the discussion in this thread, its my understand that if you want to run a typical single home load (3,4 split ACs, Refrigerator, TV, Computer, 8 Fans, 8 Tube lights) the initial cost of solar will be exorbitant and it may take 8-9 years to break-even to the cost of running these devices on Wapda supply. Am I right?

However, it may not be attractive for those who have installed UPS as UPS can also support fan and lights for 5 hours without spending any fuel. In California, the problem of theft of solar panels on house rooftops is increasing and I am sure it will also be an issue in Pakistan, especially for landscaping lights.Junaid---------------------------------------

I have heard that there are solar panels available in Pakistani markets (at least in Karachi). Prices are Rs. 150,000 and up. Does anyone have any experience of buying and/or using these panels?Junaid---------------------------------------

Waalaikumussalam,Recently, we were fortunate to meet Prof. Nasim Akhtar Khan, Vice Chancellor of Hamdard University. He is an expert in alternative energy sources, with special focus on solar, wind, geothermal, and bio-fuels. We witnessed several products, such as, electrical vehicles, houses running through windmills, cooling-huts for deserts (Thar), creation of bio-fuel, e.t.c.Here is his brief profile: http://www.petaro.org/cadets%201957-69/533-NasimAkhtar.htmHere is a blog describing a similar visit by a few journalist to Prof. Nasim Akhtar Khan at Hamdard University: http://blogarch.thenews.com.pk/blog_details.asp?id=1484&page=2Wassalam,Wali.

Assalam o Alaikum - Dear All !
Current energy crisis has indulged people to use UPSs and Generators, which are additional loads over national electric grid, gas resources and oil and equipment imports.
Solar Energy could provide a viable alternative for Pakistan, if related problems are addressed scientifically. I don't know whether our universities and industry are focusing this issue with due seriousness or relying on imported and/or conventional equipment?
We found COMSATS incubator (http://ranicautomation.com) making efforts in this regard.
A simple DC based Solar Energy System (100 W DC) may be specified as follows;
1) Solar Panel - Converts sunlight to electric voltage:
Imported, Price Rs. 150-190 x 100 = 16000-19000, Life 20 Year (about)
Immediate Research Need: Testing of Solar Panels for Throughput and Life in Pakistani Environment
2) Charge Controller - Matches the voltage output from solar panel to that required by the battery (12 V DC) and controls the charge of the battery:
Imported, Price Rs. 8000 - 18000, Life 5 Years (about)
Immediate Research Need: Design and Development of High Throughput, Long-life and Economical Charge Controller
3) Battery - Stores the electric power captured from the Sun:
Local or Imported, Price Rs. 7000 - 20000, Life 1-3 Years (about)
Immediate Research Need: Design and Development of High Power, Long-life, Economical and Easy Maintenance Batteries (may be different in design and packaging from the car batteries)
4) DC Appliances (especially fans and compressors):
Imported fan 16 inches/15 Watts, Price Rs. 3000 (about), Low Throughput
Immediate Research Need: Design and Development of Low Power, High Throughput, Long-life and Economical Fans and Compressors
HUMBLE REQUEST
Our Universities and Industries should put hands together to win this National Energy Championship !
Best Regards and Wishes
