Companies selling PV systems are concerned that if utilities add a set fee for solar customers to remain connected to the grid to take in electricity at times when the sun isn't shining, or if utilities decrease the retail credit for the times when customers send their excess generation back to the grid, people will be less likely to put panels on their roofs.
Equipped with an extremely low power, smart interface the Smart SMP pyranometers offer industry standard digital and amplified analog outputs within the well-known CMP series housings. The output range is programmed so that all SMP pyranometers have identical sensitivities, allowing easy installation and exchange for recalibration. Serial communication allows access to measurement data, instrument status, operating parameters and calibration history.
Building on the proven CMP Series design and technology that is used around the world, the new SMP pyranometers add digital signal processing and interfaces optimised for industrial data acquisition and control systems.
