Quantified Energy (QE) is a solar software company spun off from SERIS/NUS. QE specialises in AI-driven automation and analytics to support solar asset management. Its flagship solution is autonomous drone electroluminescence (EL) mapping. This in-situ, X-ray-style diagnostic tool provides cost-effective and comprehensive insights into the health of utility-scale solar farms. QE is dedicated to delivering high-quality services and cutting-edge technology to meet the evolving needs of the solar energy industry.
Key Innovations and Contributions
In 2025, QE reached a major milestone in commercial scalability by pioneering a novel approach to in-situ QA/QC testing for largescale solar asset management. In collaboration with Spanish inverter manufacturer Ingeteam, QE successfully demonstrated fully automated, contactless drone-coupled EL inspections integrated with the INGECON SUN B and C Series® Inverter. This breakthrough enabled QE to inspect 40,000 PV modules in a single 8-hour night shift — a record-setting throughput that marks a 400% improvement over previous state-of-the-art methods. By eliminating the need for manual current injections by ground teams, QE dramatically reduces labour and operational costs. This achievement sets a new global benchmark for highvolume, cost-effective photovoltaic (PV) inspections, validating QE’s readiness for industrial-scale deployment and reinforcing its leadership in solar diagnostics and risk intelligence.
In addition, QE’s contribution to industry-wide excellence is exemplified by the company’s work on the sixth edition of SolarPower Europe’s Operation & Maintenance (O&M) Best Practice Guidelines, released in February 2025. Drawing on its experience in solar diagnostics, QE defined the 6 main tests conducted at various maintenance intervals throughout the PV lifecycle to ensure the optimal performance and longevity of PV systems. This involvement underscores QE’s role as a thought leader, helping to set new global benchmarks for PV asset management and quality assurance.
Our Growth and Achievements
In December 2025, QE successfully closed its Series A funding round, raising a total of $6 million. The final closing included new strategic investments from Asian Development Bank Ventures (ADBV) and Beacon Venture Capital, the venture capital arms of Asian Development Bank (ADB) and Thailand’s KASIKORNBANK (KBank) respectively, joining initial lead investor Vertex Ventures Southeast Asia & India (VVSEAI). This expanded consortium underscores strong institutional confidence in QE’s pivotal role in advancing the bankability and financial resilience of utility-scale solar power plants globally.
The capital accelerates the integration of QE’s solution into existing quality assurance protocols, enabling operators to detect and address potential issues before they affect energy production. Solar asset owners, insurers and financiers can thereby make informed decisions about asset health early, protecting their investment returns across their 25-30 year lifecycles.
This integration is delivered by its second-generation drone EL inspection solution, which is built around a flexible pay-per-use model, allowing any partner operating a DJI Matrice drone to plug in QE’s proprietary EL camera payload and subscribe to its Technical Asset Management (TAM) platform. This unlocks the ability to perform high-throughput, lab-quality inspections anywhere in the world - making scalable, data-driven solar diagnostics more accessible than ever.
QE also achieved a major milestone in September 2025 by signing a strategic MOU with Generali China Insurance (GCI), part of the global Generali Group. This agreement establishes a new industry standard by integrating QE’s proprietary technology into GCI’s insurance underwriting and claims processes. By providing high-resolution pre-incident data that diagnoses subtle, internal solar panel defects (like micro-cracks), it enables a critical shift from reactive claims handling to proactive asset protection, showcasing QE’s role in shaping global renewable energy insurability and risk management.
Real-World Application: Asset Value Recovery
QE’s technology and expertise deliver clear financial and operational benefits to utility clients worldwide. Global renewable energy provider Engie utilised QE’s drone EL scanning to diagnose performance issues in their large-scale solar rooftop system. The EL imaging uncovered extensive microcracks and solder defects in the modules, which were contributing to a drop in performance. The data quantified a defect rate that was then used as the basis for financial recovery.
As a direct result of QE’s solution, Engie was able to work with the module manufacturer to negotiate a prorated credit that covered 8% of the full site, as shared by Tan Bin Ming, Asset Manager of Engie South East Asia. This demonstrates how QE’s solution translates directly into significant financial recovery, safeguarding the long-term value for solar asset owners globally
