Can Roof-Mounted Solar Panels Supply Enough Energy for the World’s Energy Demands? | PHILERGY German
Metro Manila, Philippines - With the cost of solar panels and other solar components becoming more affordable, roof-mounted solar energy systems are in turn becoming more appealing to home and business owners alike looking to cut down on their electric bills as well as reduce their overall carbon footprint. But is there enough roof space to generate enough solar energy to meet the world’s overall electric demands?
According to new research, it will only take 50% of the world’s rooftop surfaces covered in solar panels to deliver enough electricity to meet the world’s yearly needs. However, it is also important to determine the best locations for maximum efficiency.
Generally, rooftops located in higher latitudes such as in northern Europe or Canada can vary by as much as 40% in their generation potential across the year, due to big differences in sunshine between winter and summer. Rooftops near the equator, however, usually only vary in generation potential by around 1% across the seasons, as sunshine is much more consistent.
The research highlights Asia as one of the best locations to install solar energy systems because of its sunnier climates.
It’s vital to point out that global electricity supply cannot rely on a single source of generation to meet the requirements of billions of people. And, thanks to changeable weather and our planet’s day and night cycle, a mismatch between solar energy demand and supply is unavoidable.
The equipment required to store solar power for when it’s needed is still extremely expensive. Despite this, rooftop solar has huge potential to alleviate energy poverty and put clean, pollution-free power back in the hands of consumers worldwide. If the costs of solar power continue to decrease, rooftop panels could be one of the best tools yet to decarbonise our electricity supply.
