5 Top KPIs to Help Keep Solar Projects on Track

In Ireland, more businesses like yours are turning to solar energy to cut costs and support a greener future. But simply installing solar panels isn’t enough—to fully benefit, regular tracking and monitoring are essential. By keeping an eye on key performance indicators, you can ensure your system is running efficiently, optimise energy output, and catch any issues early on. 

So, in this blog, we’ll explore the best tools and methods for monitoring solar installations, practical steps to track performance, and solutions for common challenges. 

5 Major Key Performance Indicators (KPIs) for Solar Panels

To keep track of how well your solar panels are performing, focus on these essential key performance indicators (KPIs):

• Energy Output: This measures the total electricity your solar panels generate over a specific period. It gives you a clear picture of your system’s production and helps you see if it’s meeting your energy expectations.
• Peak Sun Hours: This metric shows the hours each day when your panels receive maximum sunlight. It’s important for assessing overall efficiency and checking if any obstacles are blocking sunlight.
• Efficiency Rate: This represents the percentage of sunlight your panels convert into usable electricity. Monitoring this rate helps you understand the effectiveness of your solar setup and spot any declines in performance.
• Degradation Rate: Solar panels gradually lose efficiency over time. Tracking the degradation rate helps you predict future performance and plan for maintenance.
• System Uptime: This measures the amount of time your system is actively producing electricity. High uptime suggests a reliable system, while frequent downtimes might indicate issues that need attention.

3 Tools and Techniques for Monitoring Solar Panel Performance

To effectively monitor solar panel performance, a variety of tools and methods are available that help you gather and analyse critical data:

1. Solar Inverter Monitoring

The solar inverter is essential for converting the direct current (DC) produced by your panels into alternating current (AC) that powers your business. Modern inverters often include built-in monitoring features, such as:

• LCD Display: Many inverters have LCD screens that display real-time information on energy output and system status, allowing for quick checks.
• Web Portal Access: Some inverters connect to online portals, giving you access to detailed metrics and historical data that can be accessed from a computer.
• Mobile App Monitoring: Most manufacturers offer mobile apps, enabling easy monitoring and management of your solar system from any location, so you’re always connected to your system's performance.

2. Dedicated Solar Monitoring Systems

Standalone solar monitoring systems provide deeper insights into the functionality and efficiency of your solar setup.

• Energy Meters: Installed between the solar panels and inverter, energy meters measure the electricity produced. These readings help diagnose issues by tracking specific output levels.
• Environmental Sensors: These sensors measure environmental conditions such as temperature, irradiance, and wind speed, all of which can impact your panels’ efficiency. This data allows you to understand how external factors affect performance.
• Software Platforms: Comprehensive software platforms provide real-time data, trend analysis, and alerts for maintenance needs, helping you stay proactive in managing system performance.

3. Online Monitoring Platforms

Many solar panel manufacturers and third-party providers offer online platforms that make it easy to track performance across various metrics:

• User-Friendly Dashboards: These platforms typically feature dashboards displaying essential metrics such as energy production, consumption, and financial savings, making monitoring simple and accessible.
• Alerts and Notifications: Customisable alerts notify you of performance issues, system anomalies, or scheduled maintenance, ensuring quick response times when needed.
• Comparative Performance Analysis: Allows you to analyse data across different time periods, identifying trends or seasonal variations and helping you optimise system settings for maximum efficiency.

Using these tools, you can closely monitor the health and productivity of your solar panels, ensuring your system operates effectively and meets your energy goals.

However, at Nusolas, you do not need to ask & search about tracking solar panels for business homes. With installation services from Nusolas, you’ll gain access to a setup designed to make monitoring simple and effective for your business.

Steps to Monitor Solar Panel Performance

To keep your solar panels performing at their best, follow these essential steps:

1. Install Monitoring Equipment: Begin by setting up all necessary monitoring devices. Proper installation and configuration are key to collecting accurate performance data.
2. Activate Online Monitoring: Register and activate the online monitoring platform, usually provided by your solar panel manufacturer or a third-party provider, to start tracking performance metrics.
3. Regularly Inspect the Inverter Display: Get into the habit of checking the inverter display daily or weekly. This quick inspection helps ensure your system is running as expected.
4. Review Data on Monitoring Platforms: Log into your online monitoring system regularly to analyse data and detect performance trends. If output falls short, investigate and address any issues promptly.
5. Compare to Expected Output: Regularly assess actual performance against the expected output provided by your manufacturer. Investigate any unusual variations to catch potential problems early.
6. Plan Routine Maintenance: Schedule routine maintenance for optimal efficiency. Clean the panels, ensure no shading issues, and inspect hardware regularly to keep your system running smoothly.

Conclusion

Monitoring and tracking the performance of your solar installations is essential to ensuring long-term efficiency and maximising your investment. By regularly checking key performance indicators, using reliable monitoring tools, and addressing common issues, your business can optimise its solar energy output. However, effective monitoring can be complex, and that’s where expert support can make all the difference.
