Dear Jafar
Salam
Yes this system has been implemented in many countries. They say that in Germany if only 10% of their rooftops are fitted with solar panels it can fulfill the electricity requirements of all of Germany. However, the problem is not the technology, the problem is the capacity and willingness of the government and institutions. For example, it took more than five years for LESCO to install smart meters at only one feeder in Lahore. Reason: Smart meters can stop electricity theft and provide accurate meter readings to the consumers.
However, to me the only long term solution to Pakistan's energy problems is investment in renewable sources mainly solar, wind and hydro. Wind and hydro require heavy investments but solar can be installed for a few thousand rupees. Take it this way if a million people in Pakistan can buy a UPS then at least five hundred thousand can also buy a solar panel of 1 KW. This adds up to 500 MW of electricity. The pay back period of solar panels without storage is roughly 3-4 years. The solar panels have a lifetime of 25 years so after the payback period it is pure profit.
However, to me the best part of all this equation is the environmental friendliness. Unfortunately nowhere in our energy policy we see environmental friendliness as a criteria for measuring a technology.
But my hunch feeling is that the new government will take more loans to buy more oil to have more circular debt. It seems that the idea of developing long term public friendly policies is non-existent in our power corridors.

While informal chat, Dr. Anjum Iqbal sahib gave a really good idea regarding energy solution as follows:The solar panel system can be more useful, if we use 'Reverse Metering' system:
- Govt. may help people buying solar panels on soft loans.
- Govt. may recommend/approve solar system specifications to be used.
- Distribution Companies can launch 'Reverse Metering' system. Excess energy, in the day, at end user premisis may be accepted by respective grid. When end user gets advantage of energy units this will make the project feasible. End user will try to install more and more solar panel at its premsis and end user will try to maintain it in a good state to get advantage of free energy.
- Generation Companies may generate more energy in the night and less in the day. Because more solar energy is available in the day.
- End user will not need a big battery bank for storage for night use.
Is this workable? What are your comments?
