Rooftop solar energy ‘can provide major portion of global electricity needs’

Owing to improved deployment capability and reduced costs, rooftop solar PV) – solar farms or roof-mounted solar panels used in home, commercial and industrial buildings – is currently the fastest deployable electricity generation technology.

Using modelling that provides much more accurate indications, the researchers conclude rooftop solar PV can supply 25-49 per cent of global electricity needs by 2050 in their study, the first detailed global assessment of energy potential from this source.
