Advantages of quantitative over manual monitoring in distributed solar systems

Updated: Jul 5, 2022

The Smart Solar Management platform (SysMap) allows quantitative assessment of distributed solar PV performance, which is a key technological approach to transform standard manual (qualitative) solar monitoring into predictive solar management.

Quantitative monitoring is a standard for large-scale solar PV facilities of utility and industrial scale, but in the commercial and residential segments it is rarely utilized due to the high cost of high-tier weather sensors and the need for sensors' maintenance and calibration. There are however also alternatives which are better suited for the distributed solar segment - one involving satellite sensing and another with sensorless approach such as Soltell's SWMP technology.

In this recent example from one of our commercial fleet clients, a 125kW rooftop PV system has experienced a malfunction in one of the string trackers, lowering the overall output of the system by nearly 10%. Obviously, when knowing something is wrong - one can notice the curve differences, but as human operators attempt to perform daily manual monitoring upon hundreds of PV facilities such nuances are typically left unnoted.

Let us summarize the outcome of technology application: a commercial 125kW PV system with 10% more solar energy production and 90% less human labor in operations. We shall continue transformimg solar O&M with advanced Industrial IoT powered automation.

Commercial and residential solar integrators - interested to know on Sensorless technology to measure PV performance and integrating it into your solar monitoring/management software or a service application? Fill-in the demo request form to get more details.
