Soluzione Solare products in the catalogue: Sunmeter Pro SM1-485PRO and Sunmeter 2 Pro SM2-485PRO class A pyranometers with an RS485 Modbus interface and the SunSpec protocol, and the Temmeter TM3 module temperature sensor with a class A PT100 element.
These are the instruments that make real output comparable with expected output: irradiance measured in the plane of the modules, plus cell temperature, give you the Performance Ratio, the one figure that separates an underperforming system from a week of cloud.
Class A is the requirement set by performance contracts and by specifications on plants above a certain size.
