Residential solar energy systems in the UAE: opportunities, challenges, and policies

Residential solar photovoltaics (PVs) can play a pivotal role in the UAE’s energy transition, yet adoption in the housing sector remains uneven. This paper presents a qualitative, policy-oriented review of opportunities and constraints for residential PV, including grid-connected rooftop systems and solar home systems. Evidence is synthesised from peer-reviewed literature, official strategies and programme documents, and stakeholder perspectives and benchmarked against leading residential PV markets (Australia, India, Saudi Arabia, and the USA). Challenges are organised into geographic, legislative, economic, social, and technical dimensions. Recent national and emirate-level initiatives have strengthened deployment pathways; however, persistent barriers, particularly fragmented and evolving regulations, tariff and crediting structures that extend payback periods, high soft costs, limited awareness, and gaps in installation quality, operation and maintenance (O&M), and supply chains, continue to constrain uptake. The review is triangulated with recent UAE household survey evidence on adoption drivers and with programme-performance studies, and reports indicative economic metrics (installed cost, payback ranges, and levelised cost of electricity) for rooftop PV. The paper concludes with an integrated roadmap linking regulatory harmonisation, streamlined permitting, targeted finance, and long-term O&M capacity and data transparency to accelerate equitable residential PV diffusion.
