A solar monitoring system is the technology that lets you track your solar panel system's performance in real time. Most modern solar installations include monitoring capabilities that connect to a smartphone app or web dashboard, giving homeowners detailed visibility into their energy production, consumption, and savings.
Monitoring systems collect data from your inverter or individual microinverters and transmit it wirelessly to a cloud-based platform. You can typically see real-time power output (in watts), daily and monthly energy production (in kWh), historical performance trends, and system health alerts.
There are two primary levels of monitoring. System-level monitoring tracks the overall output of your entire solar array, showing total production and any significant drops in performance. Panel-level monitoring — available with microinverters or power optimizers — shows the output of each individual panel, making it easier to identify and troubleshoot specific issues like shading, soiling, or equipment malfunction.
Most major inverter manufacturers offer their own monitoring platforms. SolarEdge, Enphase, SMA, and Tesla all provide free monitoring apps with intuitive interfaces that display production data, environmental impact metrics, and estimated savings.
Monitoring is valuable for several reasons beyond curiosity. It helps you verify your system is performing as expected, catch problems early before they reduce production significantly, and validate your electricity savings against utility bills. Some monitoring platforms can even detect panel-level issues and alert your installer automatically.
For homeowners earning SRECs or participating in performance-based incentive programs, monitoring data serves as official production verification, ensuring you receive the credits and payments you've earned.
