Spire Temperature Controlled Lab Flasher
The most accurate lab solar simulator for power determination, temperature coefficients and energy rating
With the TCLF, RnD and certification labs can perform:
- Accurate power determination of all new high efficiency modules
- Testing bifacial PV modules
- Accurate measurements of temperature coefficients
- Accurate determination of energy rating
The Temperature Controlled Lab Flasher (TCLF) consists of A+A+A+ Xenon Single Long Pulse Spire solar simulator and temperature-controlled chamber. The Spire lab flasher provides superior measurement accuracy and precision for critical module performance measurements.
The system delivers a Class A+ 300nm-1200nm spectrum (SPC >99%) in addition to Class A + uniformity and temporal stability in combination with a measurement repeatability of ≤ 0.15%.
The solar simulator’s unique feature of 270ms single pulse duration supports maximum module power determination of high-efficiency silicon, thin-film, PERC, HIT and multi-junction modules that exhibit internal capacitance effects.
The add-on temperature control chamber enables accurate temperature-related tests. The chamber’s temperature range is 10-85C and temperature uniformity± 1C.
The chamber can be added to existing Spire flashers.
