Rooftop solar is increasingly cost-effective for home owners, business owners, and their communities.
Individuals and businesses have been attracted not just to the environmental benefits of solar power, but also to the ability to generate their own power and to the fixed and competitive price of electricity that these systems provide. Rooftop solar is increasingly cost-effective for home owners, business owners, and their communities.
Gernaat et al. (2020) estimated that the global suitable roof area for PV generation was 36 billion square meters. This represents a potential of 8.3 PWh/y, which is equivalent to 150% of the global residential electricity demand in 2015. This demonstrates the potential of replacing traditional electricity sources with rooftop PVs.
Fig. 1. New installed capacity of renewable energy technologies globally from 2011 to 2021. Building PV generation systems can be applied on roofs (Kumar et al., 2018) and/or facades (Quesada et al., 2012), and the installed PV generation system can share the grid load.
The unique properties of roofs, such as good sunlight incidence, good ventilation conditions, no redundant shielding, and flexible tilt angle for PV panels, are advantageous for solar energy harvesting. Accordingly, roofs present the highest efficiency potential for PV generation systems in buildings (Lin et al., 2014).
Their incorporation into building roofs remains hampered by the inherent optical and thermal properties of commercial solar cells, as well as by esthetic, economic, and social constraints. This study reviews research publications on rooftop photovoltaic systems from building to city scale.
Rooftop solar is increasingly cost-effective for home owners, business owners, and their communities. Reductions in technology prices, innovative financing, and growing networks of solar installers and financial partners all helped drive down the prices for household systems in the United States by 45% percent from 2010 to 2014 [ 2 ].
