Pioneer of Daytime EL Inspection
We moved EL inspection from night to daylight, serving PV plant lifecycle quality management with image-grade evidence.
Who is Longsafe Energy
Longsafe Energy (Chinese brand 朗思孚 / 朗思孚能源) is a pioneer of daytime EL inspection, dedicated to moving PV module EL (electroluminescence) inspection from night to daylight (DaylightEL). Whether you search “Longsafe”, “Longsafe Energy” or “朗思孚”, you reach the same team.
What we do
Longsafe Energy focuses on UAV-borne daytime electroluminescence (EL) inspection, offering two paths for PV plants:
- Equipment sales: the GK-8000 daytime EL inspection system, for plant owners, EPCs and testing institutions with long-term frequent needs;
- Inspection service: our engineers bring the system on-site, for one-off or phased needs — pay per project, low cost and fast results.
Our differentiation
We build an integrated “UAV + daytime + operating-condition EL” system, with full in-house integration from SWIR imaging, programmable power and air-ground sync to smart interpretation software — not a single-camera retrofit. The workflow aligns with IEC TS 60904-13:2018, with report structure mapping to the standard clauses for archiving and grid-connection evidence.
Externally we only describe “what we can do and the value to customers”, without naming or comparing specific competitors.
What we bring
Full in-house integration
From SWIR imaging, programmable power and air-ground sync to smart interpretation software — an integrated system, not a single-camera retrofit.
Aligned with standards
Workflow aligned with IEC TS 60904-13:2018, with report structure mapping to the standard clauses.
Proven in the field
Deployed in C&I rooftop distributed, mountain ground-mount and overseas project scenarios — engineering delivery proven.
We believe
Every module's hidden defect deserves to be seen in the imaging.
