Making use of solar enegry.
submitted 6 months 16 days 15 hours ago by: amersarfraz : 3 comments
This is probably the first commercial use of Solar Panels I have seen in Lahore and I must admit that it's a perfect solution that all the outdoor (advertising and lighting) should convert to.
I know there is great potential in producing energy from solar power in Pakistan, considering it to be an extreme weather country, but I don't understand why have we not made much use of it so far.
One argument that I have heard is that Solar Energy equipment probably is very very expensive and producing energy from solar panels is not financially viable. Does anyone else has a better knowledge on that?

solar energy panels are very expensive to built, but their maintenance cost is low. The solar cells gather enrgy and store them in batteries. Like the generator in the car produces energy and store it in battery. The battery has to be changed after some time.
Another source of cheap energy generation is wind mills. The setup cost is very high but the maintenance cost is low. Holland is generating enogh energy from wind mills(I think 80% of their requirement is met through windmills). Small wind mills can prove to be benificial.
The government has also asked the owners of sign boards to find alternative solution for lighting up the signboards.

RAPID GROWTH REQUIRES EXCELLENT >MANAGEMENT. Q-CELLS AG HAS BEEN >PROFITABLE SINCE ITS FIRST FULL YEAR >OF OPERATION.
Founded at the end of 1999, Q-Cells AG began with the production of silicon solar cells in the summer of 2001 with only 19 employees. By the end of 2007, approximately 1700 people were employed at Q-Cells; the company is now the largest solar cell manufacturer in the world. In order to strengthen our position in the worldwide market, we will further expand our production site in Bitterfeld-Wolfen/Germany and start the construction of our new Malaysian production facility. Beside the mono- and polycrystalline core business we develop and produce thin-film modules, using different technologies. In the coming years we want to continue to grow faster than the market in terms of turnover and production capacity.

THE ENERGY OF THE SUN SURPASSES <>HUMAN NEEDS 7,000-FOLD. WE EXPLOIT <>THIS INEXHAUSTIBLE SOURCE.
While the oil, gas and coal reserves continue to decline, photovoltaics is developing from a niche application to an alternative to conventional energy production that is used throughout the world, providing a growing share of the power supply. In nine of ten solar systems, this is based on silicon technology. Silicon is gained from quartz sand in several melting and cleansing steps. The liquid silicon is cast into blocks. These blocks (ingots) are cut into thin discs, the so-called wafers.

Q-Cells buys these wafers and processes them into solar cells. To this end the wafers are cleaned with acids and alkaline solutions and electrophysically altered. Finally an anti-reflection film made of silicon nitride is applied to them to increase their efficiency. In a last step the electrical contacts are attached. Q-Cells sells the finished cells to solar module manufacturers.

This is good to see. At least authorities have shown some interest. Have you ever noticed a solar signboard located @ Shadman Chowk (going towards the Shadman Market), Lahore. That is about Solar Street Lights if I am not wrong. And that particular signboard is solar powered itself...
Govt. should run the campaign on itself as well. They should cut their power usage. They should charge 5 star hotels double... Half street lights should be powered off in the night. There are several options which the authorities can adopt.
Let's see...
