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

Rooftop solar PV (photovoltaic) panels could supply more than 25 per cent of the world’s electricity needs by 2050, according to a team based in UCC.

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.
