Quantified Energy, a Singapore-based deep-tech company, has announced the successful completion of its Series A funding round, led by Vertex Ventures Southeast Asia & India. This investment aims to accelerate the global expansion of Quantified Energy’s drone-based solar inspection technology, which was developed as a spin-off from the Solar Energy Research Institute of Singapore at the National University of Singapore.
Founded in 2021, Quantified Energy has pioneered an autonomous drone electroluminescence mapping solution, providing inspection services for utility-scale and commercial solar systems. The company recently completed the world’s largest electroluminescence inspection, covering over one million photovoltaic modules in just three weeks. This achievement underscores the growing demand for efficient solar inspection solutions, as BloombergNEF projects 4.5 terawatts of new solar capacity by 2030.
The funding will enable Quantified Energy to roll out its second-generation drone inspection solution globally. The company plans to introduce a “pay-per-use” model for DJI M300/M350 drone operators, allowing them to perform high-throughput inspections. CEO Yan Wang stated, “With this new round of funding, we will be rolling out our second-generation drone EL inspection solution globally.”
Quantified Energy has already deployed its solutions across Asia, Europe, Oceania, and the Middle East. A recent Memorandum of Understanding with TÜV Rheinland at Intersolar Europe 2025 will further drive the adoption of their technology in European markets. Vertex Ventures Partner Puiyan Leung commented, “We are excited to work with Quantified Energy to bring their innovations to the global solar market.”
With this strategic investment, Quantified Energy is poised to enhance solar asset management and financing, contributing to the renewable energy transition worldwide.
