Quantified Energy (QE), a Singapore-based deep-tech company, announced its Series A fundraise led by Vertex Ventures Southeast Asia & India on Tuesday.
With this latest funding round, QE will accelerate its global business development efforts and double down on product innovations to cater to the needs of the fast-growing solar industry, the firm said in a statement.
“With this new round of funding, we will be rolling out our second-generation drone electroluminescence (EL) inspection solution globally,” the firm’s Chief Executive Officer Dr. Yan Wang said.
“Any partner operating a DJI M300/M350 drone can plug in QE’s EL payload and subscribe to our ‘pay-per-use’ model—instantly unlocking the ability to perform high-throughput EL inspections for clients,
“Through this approach, we contribute to safeguarding the exponential growth of the solar photovoltaics (PV) industry,” he added.
He also highlighted that QE’s founders are solar researchers from Asia and Europe who came together in Singapore with a shared mission to make every PV module count throughout its lifetime.
According to the statement, the global solar market is experiencing rapid growth, with BloombergNEF projecting up to 4.5 TW of new solar PV capacity to be installed between now and 2030.
Large-scale systems remain the key driver of this expansion.
By enabling precise and non-destructive in-situ diagnostics for solar power systems at unprecedented throughput, QE empowers solar asset owners and financiers to reduce the risk of premature degradation and improve safety.
This, in turn, helps optimize asset performance throughout a solar PV system’s lifespan, leading to higher energy yield and improved return on investment.
Founded in 2021 as a spin-off from the Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore, QE is a company aims to advance solar asset performance through artificial intelligence (AI)-driven inspection and analytics.
By combining drone technology with proprietary software, QE delivers actionable insights to optimize the efficiency, reliability, and sustainability of solar installations.
The firm developed an autonomous drone EL mapping solution and provides inspection services for utility-scale and commercial solar systems.
The company has deployed its solutions across Asia, Europe, Oceania, and the Middle East.
Last year, QE completed the world’s largest EL inspection, covering over one million PV modules at a single site within three weeks.
Recently, QE signed a Memorandum of Understanding with TÜV Rheinland at Intersolar Europe 2025 in Munich, Germany, to drive the adoption of drone-based EL mapping in key European markets such as Spain and Portugal.
This follows multiple successful pilot projects between the two companies across the region.
“Solar power is a cornerstone of the global renewable energy transition. QE’s unique capabilities are well-positioned to transform how solar assets are managed and financed,
“We are excited to work with Quantified Energy to bring their innovations to the global solar market,” said Puiyan Leung, Partner of Vertex Ventures Southeast Asia and India.
