6 FAQs about [Rooftop photovoltaic energy storage capacity]

How big is the potential for rooftop photovoltaic?

The global suitable roof surface area was assessed at 36 billion m 2, or 4.7 m 2 capita −1, leading to a potential for rooftop photovoltaic of 8.3 PWh y −1, roughly 1.5 times the 2015 global residential electricity demand.

How much electricity does a rooftop photovoltaic use?

The rooftop photovoltaic cost-supply curves show a potential of 8.3 PWh y −1 in 2015 on a global suitable roof area of 36 billion m 2 and cost levels of 0.09–0.5 $ kWh −1. The total potential of 8.3 PWh y −1 is roughly 1.5 times the 2015 global residential electricity demand.

Is rooftop solar PV a viable alternative to residential electricity demand?

The results show that current global rooftop potential is 1.5 times the residential electricity demand. The market penetration of rooftop solar PV is much more dependent on socio-economic and policy factors than on the biophysical potential. Several aspects require further discussion.

Do rooftop solar systems need energy storage?

Energy storage solutions: As rooftop solar systems continue to grow in popularity, the need for energy storage becomes more critical. Batteries like the Tesla Powerwall offer residential users the ability to store excess solar energy produced during the day for use in the evening when the sun is no longer shining.

What is the potential of rooftop PV?

Global estimated potential 8.3 PWh y −1: 1.5 times residential electricity demand. Scenarios show key role for rooftop PV but regional characteristics crucial. Income levels and grid electricity prices dominate regional deployment. Low-irradiation western Europe better than high-irradiation Middle East.

Do rooftop PV resources affect solar energy generation in China?

It is observed that areas with sufficient rooftop PV capacities have moderate to inferior PV efficiency (CF ≤ 0.14), while building roof resources are scare in areas with high PV efficiency (CF close to 0.20). Such spatial inconsistency between roof resources and solar resources somehow reduces the electricity generation of rooftop PVs in China.
