Harnessing rooftops to generate solar power

A company is installing solar cells on rooftops, then sharing proceeds from the electricity sale with the houseowners.

If Dr Nurul Muiz Murad has his way, every rooftop in Malaysia will be covered with solar photovoltaic (PV) panels to generate electricity. Why not, considering that Malaysia enjoys relatively long hours of daylight, and there are lots of rooftops with no conceivable use other than to keep the elements out.
