The PV-Blocks (MTI.AWS.EK.PVB) system is a unique and versatile solution designed to outdoor test any type of PV technology, including Silicon, Thin-Film, Perovskite and Hybrid modules, organic PV and even the latest high-capacity Bi-facial modules. The advanced off-grid and grid-connected research systems are fully compatible with the latest PV technologies in development and are scalable to test multiple modules in parallel. During long-term exposure tests, automatic measurements can be scheduled for continuous data retrieval of the measurable module parameters. Up to x32 modules or more can be connected to the PV-Blocks base pack to measure each individual I-V curve and characteristics under MPP load conditions. Similarly, individual temperature measurements are performed on the PV module. If modules are mounted with different tilt angles, different pyranometers or reference cells can be used to measure the total radiation in plane with the module.
The system can be expanded with a meteorological station, sun-tracker (DNI, GHI, DHI) and spectroradiometer. The PV-Blocks system is modular and can be adjusted to various system configurations. It can be expanded for simultaneous measurements of multiple modules of different currents, voltages and power ratings. The irradiance (GHI, DNI, DHI, POA) and module temperature can be measured simultaneously with the voltage and current measurements to calculate to STC or equivalent standards.
The internal Linux computer and special software combine the data from all sensors with the I-V measurements. Integration of spectral measurements is possible with EKO spectroradiometers.
The turn-key PV-blocks system is designed for outdoor and laboratory use and can be supplied with a weatherproof enclosure making it easy to install close to the PV setup.
