What Sinton Instruments does

Sinton Instruments (legal entity Sinton Consulting Inc.) is a Boulder, Colorado-based privately held company founded in 1992 by Ron Sinton. It designs and manufactures test and measurement instruments for the silicon photovoltaic (PV) manufacturing value chain, spanning bulk silicon ingot/wafer characterization, cell-level light I-V and Suns-Voc analysis, and module-level flash testing. The company is best known for commercializing the quasi-steady-state photoconductance (QSSPC) method in 1994 and for its patented voltage modulation technique, which together underpin its WCT-120 wafer testers, BCT-400/BLS-I bulk lifetime testers, FCT-650/FCT-750 cell testers, Suns-Voc MX, and FMT-500 module testers. Its instruments are referenced as the de facto lifetime-measurement standard in laboratories worldwide, comply with the SEMI PV-13 standard, and have been deployed in over 600 units globally, with module testers having characterized more than 20 GW of product.

The company sells through a direct enterprise quote-based motion supplemented by regional channel partners in China (GCD, HTTR), Taiwan (GSI), and India (Ikshana Automation), targeting silicon solar cell manufacturers (primary), wafer/ingot producers, and module manufacturers. Revenue is generated from hardware sales of instruments and spare parts, recurring software updates, and calibration services, with a small workforce of 11–50 employees. Sinton has supplemented internal R&D with non-dilutive grants from the U.S. Department of Energy SunShot Initiative and NREL. In 2025 the company extended beyond its industrial PV core with ChargeBug, a consumer mobile app that uses grid carbon-intensity data to advise EV drivers on optimal charging windows.

Core offering

Sinton Instruments designs and manufactures photovoltaic test and measurement instruments used in silicon PV process control across the solar manufacturing value chain — from bulk silicon ingot/brick characterization, to wafer lifetime testing, to in-line cell testing (light I-V and Suns-Voc), to flash module testing. The product portfolio includes BCT-400/BLS-I bulk lifetime testers, the WCT-120 series wafer testers, FCT-650/FCT-750 cell testers, the Suns-Voc MX process-control tool, and the FMT-500 module tester, all built on proprietary QSSPC and voltage-modulation measurement techniques. The company also sells software updates, calibration kits, spare parts, and an EV charging forecast mobile app (ChargeBug).

Product overview

Sinton Instruments offers a comprehensive portfolio of photovoltaic testing and measurement instruments for silicon solar cell and module manufacturing. The product lineup includes: BCT-400 and BLS-I bulk lifetime testers for silicon ingot/block characterization; WCT-120 series wafer lifetime testers including standard, temperature-dependent (WCT-120TS), and photoluminescence (WCT-120PL) variants, plus inline IL-800 for production wafer testing; cell testers FCT-650/FCT-650SE and FCT-750 for light I-V and Suns-Voc analysis; Suns-Voc MX for post-diffusion process control; FMT-500 flash module tester for module characterization; ST-100 spectrometer for solar simulator classification; calibration kits and spare parts. The company also offers ChargeBug, an EV charging optimization app. All instruments are based on proprietary measurement techniques including quasi-steady-state photoconductance (QSSPC) and voltage modulation methods.
