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
Anjum Iqbal
