Check out Solmetric’s new PVA-1500 PV Analyzer Kit at SPI

Solmetric PV analyzer

The PVA-1500 PV Analyzer Kit is a 1500 volt I-V curve tracer with built-in PV performance modeling and advanced wireless irradiance, temperature and tilt sensing from Solmetric. It provides unprecedented measurement throughput and accuracy and delivers deep insight into the performance of your arrays. You can see it for yourself at Solar Power International, booth 352.

In addition to the 1500V measurement capability, the PVA-1500 has a few additional enhancements over its predecessor, the PVA-1000S, including using WiFi to communicate to your tablet or laptop. This eliminates the USB dongle required for the PVA-1000S.

What’s new?

For each string, the PV Analyzer measures the I-V (current vs. voltage) and P-V (power vs. voltage) curves with a single button click. The measured results are compared to the expected performance, taking into account the irradiance and module cell temperature at the time of the I-V measurement. The I-V Unit communicates wirelessly to your Windows tablet or laptop (not included), enhancing safety and allowing freedom of movement during testing. Automated data analysis and reporting save you time.

The PV Analyzer is designed to work as hard as you do. High measurement throughput means it can measure 1 MW in less than 2 hours–even in hot environments where other curve tracers shut down. In an example PV system with 1300V Voc, 16 strings per combiner box, and 5 minutes to move to next combiner box, the PVA can make more than 800 measurements at 25°C ambient and 250 measurements at 45°C ambient. The incident angle corrected SolSensor is able to make accurate irradiance readings in lower light conditions extending your working window.

I-V curve testing is the preferred method for commissioning, O&M, and troubleshooting of PV arrays because it provides the most complete performance measurement possible. Populations of curves can be analyzed quickly for outliers and data can be archived as a baseline for future reference if performance questions arise.

Have you checked out our YouTube page?

We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.

Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.

We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
