The International Renewable Energy Agency (IRENA) has released a new report that explores the potential for solar PV to contribute to global energy needs. The report, titled "Which Energy Future? Rooftop Solar PV in a Decarbonising World", provides a detailed analysis of the potential for rooftop solar PV to provide a significant share of global energy demand by 2050.
According to the report, the global potential for rooftop solar PV is more than 4,000 gigawatts (GW), which is more than double the global electricity demand in 2016. The report notes that, while the majority of this potential is in developed countries, the greatest growth in rooftop solar PV is expected to occur in developing countries.
The report provides a detailed analysis of the economics of rooftop solar PV, and finds that the levelised cost of electricity from rooftop solar PV has fallen by more than 70% since 2010. The report also finds that the payback period for rooftop solar PV systems has fallen from around 15 years in 2010 to less than 5 years in many markets today.
IRENA’s Director-General, Adnan Z. Amin, said that the report shows that "rooftop solar PV is a increasingly attractive option for households and businesses
Which Energy Future Rooftop Solar
Rooftop solar is an exciting energy future for many reasons. It is renewable, clean, and cost-effective. It can reduce or even eliminate electricity bills, and provides a great way to reduce our dependence on fossil fuels. It is also a great way to increase property value and aesthetic appeal. Rooftop solar panels can be installed on virtually any roof, regardless of the angle or orientation. Furthermore, they require little to no maintenance, so they can provide clean energy for years to come. With the right incentives and support, rooftop solar can be a great way to reduce our environmental impact and improve our energy future.
