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.
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.
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.
Most rooftop PV stations are Grid-connected photovoltaic power systems. Rooftop PV systems on residential buildings typically feature a capacity of about 5–20 kilowatts (kW), while those mounted on commercial buildings often reach 100 kilowatts to 1 megawatt (MW). Very large roofs can house industrial scale PV systems in the range of 1–10 MW.
Rooftop Solar photovoltaics (RTSPV) technology as a subset of the solar photovoltaic electricity generation portfolio can be deployed as a decentralized system either by individual homeowners or by large industrial and commercial complexes.

Particularly in the residential sector, rooftop PV systems have seen significant adoption as decentralized electricity generators 3. Projections from the International Energy Agency (IEA) indicate that rooftop PV capacity is expected to reach 143 GWp by 2024, a substantial increase from 58 GWp in 2018 4.

The government of Eritrea has received a $49.92 million grant from the African Development Bank to fund a 30 MW photovoltaic plant in the town of Dekemhare, 40 km southeast of the capital Asmara. It will be the country's first large-scale solar plant.
The Government of Eritrea is the beneficiary of the grant, and the Ministry of Energy and Mines is responsible for its implementation. Eritrea experiences inadequate, unreliable, expensive and polluting electricity supply. The available capacity is 35 MW for a peak demand of about 70 MW.
When completed it will become the largest solar zone in the world. Financing Approval date 1 March 2023 Project name: Dekemhare 30-megawatt photovoltaic solar power plant project in Eritrea.
Part of the grant will also be allocated to technical assistance and capacity building to improve the operational performance of the grid and ensure the sustainability of the results achieved and the overall development of the Eritrean power sector.
From January–March 2025 we tracked significant rooftop PV fire incidents worldwide on commercial and agricultural buildings. Each entry lists date, what burned, where, suspected cause when known, and notable consequences like roof damage, smoke, water-damage, or PV debris. A house fire in Kleve, Germany involving integrated photovoltaic roof tiles required about 65 firefighters and lasted nearly five hours, with the blaze mainly confined to the roof and no injuries reported. This AllShield tracker lists each incident with date, location, likely cause and impact, plus verified sources and expert insight—so insurers and owners can benchmark risk and improve safety. We. According to PV Watch, a rooftop fire broke out at the Gotion Energy manufacturing base in Changzhou's Jintan District on the afternoon of July 21, sending thick plumes of smoke into the sky and drawing widespread attention from passing residents and online observers. The fire affected a single-family home and required about 65.
