Engineered to meet rigorous IEC 60904-9 Class AAA compliance and high-bandwidth dynamic load testing. Trusted by Silicon Valley clean energy labs, aerospace test facilities, and utility-scale PV module exporters.
As Northern California accelerates its transition toward 100% clean energy mandates under California Code of Regulations (Title 24) and the California Public Utilities Commission (CPUC) NEM 3.0 net metering framework, the demand for precision solar simulation and power electronics validation has reached unprecedented complexity. San Francisco, serving as a global nexus for CleanTech venture capital, academic research institutions (such as Stanford University and UC Berkeley), and national laboratories (Lawrence Berkeley National Laboratory - LBNL), requires state-of-the-art test infrastructure to benchmark next-generation photovoltaic technologies.
As an established Solar Simulator Manufacturer & Exporter serving San Francisco and the wider Bay Area tech corridor, our engineering architecture bridges the critical gap between theoretical solar cell research and commercial-scale grid integration. By combining IEC 60904-9 Class AAA light simulation with high-slew-rate programmable AC/DC electronic loads and regenerative power converters, our test systems enable engineers to characterize photovoltaic modules, microinverters, energy storage system (ESS) interfaces, and perovskite-silicon tandem cells under reproducible laboratory environments.
Accurate IV (Current-Voltage) curve tracing of solar cells and modules requires strict adherence to international standard IEC 60904-9 (Edition 3). A solar simulator must achieve top-tier "Class AAA" status across three fundamental optical parameters:
The spectral irradiance distribution must not deviate by more than ±25% (0.75 to 1.25 ratio) from the standard AM1.5G (Air Mass 1.5 Global) solar spectrum across specified wavelength intervals from 400 nm to 1100 nm. Our multi-channel LED light engines allow sub-nanometer spectral tuning to match custom AM0 space or indoor lighting spectra.
Irradiance uniformity across the designated test field must remain strictly within < 2%. Achieving spatial uniformity over large-area commercial modules (exceeding 2.5m × 1.3m) prevents localized hot-spots or fill-factor distortion during high-throughput factory flash testing.
Light intensity variation over the IV sweep duration must not exceed Short-Term Instability (STI) of < 0.5% and Long-Term Instability (LTI) of < 2%. This temporal stability ensures high-precision MPPT (Maximum Power Point Tracking) efficiency calculations without optical flicker noise.
San Francisco's unique geographical, economic, and technological ecosystem drives specific operational requirements for solar simulators and power test setups.
Leading clean-tech incubators in South San Francisco and Sunnyvale are pioneering tandem photovoltaic cells reaching theoretical conversion efficiencies above 30%. These multi-junction devices exhibit strong capacitive effects and slow luminescence decay. Our steady-state LED solar simulators provide adjustable flash durations (from 1ms up to continuous steady-state) to eliminate hysteresis during high-accuracy IV measurements.
With California's NEM 3.0 tariff shifting consumer and commercial ROI focus heavily toward Battery Energy Storage Systems (BESS), solar installations in the Bay Area require hybrid inverter compliance. Our programmable AC/DC electronic load banks and simulated PV sources allow San Francisco system integrators to dynamic-load-test microinverters under simulated rapid cloud transients and voltage ride-through (LVRT/HVRT) grid conditions.
For satellite builders and high-altitude pseudo-satellite (HAPS) manufacturers operating near Mountain View and Moffett Field, standard terrestrial spectrum (AM1.5G) is insufficient. Our custom continuous solar simulators feature tunable AM0 spectrum filters, vacuum-chamber-compatible optical collimators, and thermal control stages designed for orbital solar array verification.
San Francisco Municipal Transportation Agency (SFMTA) and private corporate shuttle fleets are rapidly deploying solar-powered microgrids. Testing high-power DC fast-charging infrastructure coupled directly to solar arrays demands massive dynamic loads. Our 1000KW 3-Phase AC load banks and high-power DC regenerative loads deliver stress-testing capabilities up to 600Vln / 1039Vll to simulate real-world municipal loads.
Bifacial PV modules are now standard across commercial rooftop projects in the Bay Area and utility-scale developments in California's Central Valley. Evaluating rear-side irradiance reflection (albedo) requires dual-sided solar simulation. Our advanced test rigs incorporate independent bottom light banks to measure rear-side gain factor under calibrated 100 to 300 W/m² secondary irradiance.
California's mandated solar energy systems for new residential and commercial construction have elevated the quality control bar. Exporters and distributors shipping solar panels into San Francisco ports must provide verified factory flash-test data backed by ISO/IEC 17025 accredited solar simulator calibrations to prevent supply chain litigation.
California utilities (including PG&E) require grid-tied solar inverters to support Rule 21 smart inverter functions. Our programmable solar simulators emulate fast IV response curves, enabling inverter manufacturers to validate dynamic anti-islanding, reactive power control (VAR), and frequency response under varying solar flux conditions.
Selecting the correct solar simulator radiation source depends on target DUT (Device Under Test) chemistry, throughput requirements, and thermal management limits.

With over two decades of engineering excellence in high-power test instrumentation, programmable AC sources, electronic loads, and solar light measurement systems, our organization delivers complete testing solutions built for lifetime reliability. Serving manufacturers, research labs, and exporters in San Francisco and globally, we combine direct manufacturing oversight with localized technical support.
Every solar simulator and power measuring system ships with comprehensive spectral irradiance maps, spatial uniformity charts, and NIST-traceable calibration certificates required for regulatory compliance.
Our instruments feature native automation interfaces including GPIB, USB, RS485, Ethernet/LAN, and EtherCAT. Native IV-curve tracing software enables automatic extraction of Voc, Isc, Pmax, Fill Factor (FF), and efficiency metrics.
We provide rapid air and ocean export logistics directly to the Port of Oakland and San Francisco International Airport (SFO), complemented by regional field engineers for on-site commissioning and annual lamp/LED optical recalibration.
Our simulators undergo rigorous optical testing using calibrated spectroradiometers and multi-point sensor grids. We certify Class AAA performance across all three critical areas: Spectral Match (400-1100nm spectrum within 0.75-1.25 of AM1.5G), Spatial Non-Uniformity (< 2% across total working area), and Temporal Instability (STI < 0.5%). Detailed calibration documentation is supplied with every system.
Yes. Modern high-efficiency N-type TOPCon, HJT, and Perovskite cells exhibit significant capacitive charge storage during fast IV sweeps, which can distort efficiency measurements. Our steady-state LED solar simulators allow programmable sweep rates and variable pulse widths up to continuous illumination, enabling true equilibrium IV measurement without dynamic capacitance distortion.
We specialize in tailored optical configurations, including micro-area light guides for sub-millimeter cell research, multi-channel LED spectral tuning (permitting custom atmospheric or AM0 extraterrestrial spectra emulations), temperature-controlled vacuum sample stages (-40°C to +120°C), and automated probe stations with Integrated Lock-In Amplifiers for quantum efficiency (EQE/IPCE) analysis.
Standard bench-top electronic loads and compact LED solar simulators are typically dispatched within 2 to 3 weeks via direct air freight to San Francisco International Airport (SFO). Customized industrial cabinet units or large-area flash solar simulators ship via ocean freight to the Port of Oakland with full door-to-door customs clearance, white-glove rigging, and local field commissioning options.
Our High-Power Regenerative AC/DC Load Banks convert the electrical energy extracted during solar inverter burn-in or battery discharge testing back into clean 60Hz AC utility power with up to 95% efficiency. This dramatically reduces electricity consumption, lowers HVAC heat dissipation requirements in Bay Area facilities, and aligns with local corporate sustainability mandates.
