تحریر: ایم بلال ایم

سولر پینل صرف بجلی بنانے والے نہیں ہوتے بلکہ ان کی مدد سے دھوپ سے مختلف چیزیں، جیسے پانی وغیرہ بھی گرم کیا جاتا ہے۔ اس تحریر میں ہم صرف ان سولر پینل کی اقسام دیکھتے ہیں جن سے بجلی بنائی جاتی ہے اور یہ کہ ان اقسام میں سے پاکستان کیلئے کونسی بہتر ہے۔
بجلی بنانے والے سولر پینل کو پی وی یعنی فوٹو وولٹیک پینل کہا جاتا ہے۔ سولر پینل دراصل سولر سیل کا مجموعہ ہوتا ہے، جس میں متعدد سولر سیل جوڑ کر ایک پینل تیار کیا جاتا ہے۔ سولر سیل کی عمومی عمر ۲۰ سے ۲۵ سال تک ہوتی ہے، لیکن یہ نہیں کہ اس عرصے کے بعد سولر سیل کام کرنا چھوڑ دیتا ہے، بلکہ اس کی کارکردگی کسی حد تک کم ہو جاتی۔ سولر سیل کی بنیادی طور پر تین اقسام ہیں، مونو کرسٹلائن سیل، پولی کرسٹلائن سیل اور تھِن فلم/ایمارفیس سیل۔
مونو کرسٹلائن، جیسا کہ نام سے ظاہر ہے، اس کا ایک سیل سیلیکون کے ایک کرسٹل سے تیار ہوتا ہے۔ یہ سیل عموماً کالے رنگ کا ہوتا ہے اور تھوڑی روشنی میں بھی کام کرتا ہے۔ مونو کرسٹلائن سیل پر پڑنے والی روشنی میں سے ۱۸ فیصد جذب کر کے اس سے بجلی بنا دیتا ہے۔ یہی وجہ ہے کہ سولر سیل میں یہ سب سے مہنگا ہوتا ہے اور سب سے حساس بھی سجھا جاتا ہے۔

Chicken Droppings to Power Biogas Plants in Rizal

Chicken Droppings to Power Biogas Plants in Rizal

PHILIPPINES - Chicken droppings will soon be widely used in Rizal to power biogas plants, as Agham Party List Reprersentative Angelo Palmones teams up with DOST IV-A Director Fernando E. Ablaza in designing the new digester.
With methane as one of the major causes of the greenhouse effect, methanation or the generation of biogas from biomass fermentation has thus come to mean better things for most. With this in sight, Mr Palmones early this month inspected a biogas digester plant in Ibaan, Batangas to check the viability of his proposed project.

Together with Mayor Danny V. Toreja and officer-in-charge Emelita P. Bagsit of the Office of the Regional Director of DOST IV-A, the group reviewed the operations of some 44 digester units in Ibaan. With all units working 99 per cent, most of which under the communal system of piped-in methane gas for cooking and lighting needs, Mr Ablaza is confident that the new design for chicken droppings will work just as well.

Initially developed for Quezon, the design is targeting the poultry industry of Rizal. To ensure compatibility of digester design and material charge, Mr Ablaza redrew the mixing chamber of the biogas digester to suit the consistency and texture of chicken droppings. He added a system for reducing unwanted biological and chemical components of the droppings prior to their disposal. Lastly, he added a filtration procedure for the recovered gas to increase its combustibility.

Countrywide efforts have been attempted by various sectors to improve use of renewable energy sources such as biogas.

Mr Ablaza has led most of these efforts, facilitating construction since 1993 of more than 300 units all over the country worth nearly P27 M in investments. These collectively supply annually 762,000m3 of biogas; enough to fuel cooking and lighting needs of 2,285 families with six members for one year. The annual supply of biogas is equivalent to P17 M in potential fuel savings, assuming that all units are 40 per cent efficient (optimum efficiency in tropical areas) in fuel generation.

Pak student excels in Abu Dhabi competition

Pak student excels in Abu Dhabi competition

Islamabad: Ali Raza Randhawa, a final-year student of BS Electrical Engineering at the University of Engineering and Technology, Lahore, snatched a win for Pakistan during the Elevator Pitch Contest held in Abu Dhabi.

The event was held at Abu Dhabi Women’s College, Khalifah Campus. Over 70 short-listed semi-finalist teams, out of 4,500, pitched their idea 20 times to 20 CEOs, Presidents, Directors, and Saudi Khalifahs, who were representing

different companies at a two-day entrepreneurship workshop.

The event was jointly organised by GIST (CRDF Global) and MIT Enterprise Forum Pan Arab Region. Sheikha Lubna Al-Qassimi, Minister of Foreign Trade for UAE, and Sheikh Nahayan Mabarak Al Nahayan, Minister of Higher Education and Scientific Research, were chief guests on the occasion.

Ken Morse, Founding Managing Director, MIT Entrepreneurship Centre, trained the young entrepreneurs around the world during the workshop.

Pak-Energy Solution, founded by Randhawa, is committed to becoming pioneer of green revolution in Pakistan by providing cost-effective

energy solutions to the masses.

“The farmers cannot afford high prices of chemical fertilizers whereas use of these chemicals is the prime cause of damage to the quality of food in Pakistan. To cater this problem, Pak-Energy Solution is introducing an affordable biogas plant,” says Randhawa.
