PV Doctor Surpasses 2 GWp and Launches Its First Singapore PV Systems Performance Benchmarking Report
PV Doctor Pte. Ltd. (“PV Doctor”), a leading solar performance analytics and asset management platform has surpassed 2 GWp of solar assets under management, doubling its portfolio in just six months since reaching the 1 GWp milestone in November 2025. The company now monitors over 2,000 across 22 countries, reinforcing its rapid expansion and growing relevance across both emerging and mature solar markets.

Alongside this milestone, PV Doctor has released its first Singapore PV Systems Performance Benchmarking Report, offering a data-driven view into real-world system performance of 14% of the total installed solar capacity. Drawing on full-year 2025 data from 600+ systems, the report provides a rare, ground-level perspective on how assets actually perform in operation, rather than how they are expected to.
The findings highlight performance differences between residential and commercial & industrial (C&I) segments. Residential systems tend to underperform projections, largely due to suboptimal roof tilt angles misaligned with equatorial solar conditions, compounded by shading from surrounding structures and vegetation. These design-related constraints result in structural energy losses across a large share of installations. Commercial and industrial systems, by contrast, show a wide range of performance outcomes, reflecting inconsistencies in operational practices and significant untapped optimisation potential across portfolios.
The report also examines system ageing and degradation, showing that while some assets maintain stable performance over time, others experience accelerated decline. Importantly, this variation is more often linked to operational and environmental factors than to intrinsic module degradation, confirming that a significant portion of losses are both identifiable and recoverable.
PV Doctor's experience across its portfolio demonstrates that performance gaps are not permanent. Through targeted interventions, including repowering and rectification works, underperforming systems can be significantly restored. Case examples within the report document the successful revival of previously underperforming assets and measurable performance gains across operational sites.

PV Doctor continues to strengthen its analytical capabilities, supported by an active and growing artificial intelligence team. Its first published work in this domain will be presented at the 54th IEEE Photovoltaic Specialists Conference in the United States, demonstrating how AI-powered frameworks can automate the identification and diagnosis of performance issues across distributed solar portfolios, reducing false alarm investigation time by up to 90% while preserving engineering capacity for genuinely complex diagnostics. By combining research-driven methodologies with real operational data, PV Doctor is positioning itself at the forefront of intelligent, scalable solar asset management.
“Surpassing 2 GWp in just over one year of full operations reflects the growing demand for transparent and actionable insights in solar asset management," said Dr. André Nobre, Co-Founder & Managing Director of PV Doctor. "Our Singapore Benchmarking Report confirms that while deployment has scaled rapidly, performance optimisation remains a largely untapped opportunity. Most losses are recoverable or can be significantly reduced — and that is precisely where PV Doctor creates value for its clients, in Singapore and globally.”
PV Doctor is a pioneering solar asset performance management platform, spun off from the Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS). Built on over 15 years of world-class photovoltaic research and anchored in real-world operational expertise, the company monitors and manages over 2,000 systems across 22 countries, helping asset owners maximise energy yield, recover underperforming assets, and protect long-term returns.
