Solar Panels Monitoring

What is Solar Panels Monitoring?

A solar panel monitoring system is designed to analyze panel performance and track results over time. These specialized systems collect real-time data on a variety of metrics, such as current, voltage, weather conditions, and overall energy generation.

Real-time monitoring is critical to quickly identifying and correcting any problems that affect energy output or the overall condition of the panels. Monitoring systems can provide detailed insights into the solar array, keeping panels functioning optimally and preventing unidentified issues hindering power generation.

Why is Panel Monitoring Important?

Panel monitoring allows solar plants to understand each panel’s solar generation and health. Monitoring systems typically cover other related components, such as inverters and charge controllers, so any issues can be detected as soon as possible.

Without solar panel monitoring systems, it can be difficult to understand how to monitor solar panel production. While you may still have some metrics available, a dedicated monitoring system enables predictive maintenance, the need for ad hoc repairs, and boosts revenue.

Core Solar Monitoring Components

Solar panel monitoring software will vary in capabilities by vendor, but generally, it will provide real-time data for several key components involved in power generation. 

Monitoring these components individually provides a holistic vantage point of the entire operation. The core components that need to be monitored are:

• Solar panels: Panels are the workhorses of any solar plant, continuously using photovoltaic cells to convert sunlight into electricity. Drone inspections with thermal cameras help identify any defects in cells while monitoring systems focus on power output.
• Power optimizers: A power optimizer is installed at the module level and aims to optimize the power output of individual panels. Monitoring optimizers provide real-time voltage, current, and module-level performance data.
• Charge controllers: These components regulate how batteries are charged and discharged in off-grid systems. A charge controller monitors the current charge, solar panels, and consumption. Monitoring systems are able to access this data to identify possible issues.
• String inverters: Solar panels generate DC power but typically need to be converted to AC power to be sold to the grid. Monitoring systems grant additional insights into energy production, current, and voltage. Additionally, string inverters are monitored to track the total output of multiple panels.

A monitoring system with access to each of these systems can inform solar panel maintenance schedules and trigger alerts when ad hoc inspections are necessary.

Key Benefits of Solar Panel Monitoring Systems

Solar panel benefits offer a wide range of potential benefits for solar plants, ranging from increased revenue to customized alerts. Let’s explore some of the most valuable benefits of a solar panel monitoring system to demonstrate why they’re well worth the investment.

Increase Revenue by Maximizing Output

Without a robust monitoring system, any issues that are overlooked by technicians during an inspection might not be identified until the next inspection. In the meantime, productivity and revenue will be reduced.

Conversely, monitoring systems provide ongoing insights into power output throughout the plant. Issues with a component will be quickly identified and resolved, maximizing output and revenue in the process.

Stay Updated with Emails and Notifications

While the specific options will vary by platform, you’ll typically be able to set up alerts, notifications, and email reports with a high degree of customization. Rather than relying on technicians watching the dashboard, alerts and emailed reports keep everyone informed.

For example, you can have a summary report generated at the end of every day for later review. Additionally, alerts can be triggered if any specific metrics fall below a predefined threshold. Texts or emails can be sent to technicians so they can follow up on the problem and return the plant to optimal performance.

Robust Data and Awareness of Operations

A monitoring system makes it easy to see how much power the plant produces. Personnel can also review monitoring data as necessary for the specific roles. Beyond the high-level overview, you can drill down into specific metrics for each panel and inverter, which can help inform maintenance or inspection scheduling.

Monitoring systems allow technicians to watch the entire solar plant so any anomalous issues can be identified as soon as possible, on top of any automated alerts. 

Additionally, historical data can generate any necessary reports to present to stakeholders or investors quickly within the dashboard.
