Performance monitoring allows both you and TFS to monitor your solar electric (PV) system remotely via the Internet. TFS regularly assesses your system’s electricity production to be certain that your system is continuously operating at peak performance.

Performance monitoring clearly conveys how well your PV system is working by displaying the exact amount of energy it’s producing, environmental benefits, and total amount of financial savings your system has provided since installation. In real time, monitoring records, stores, and presents your system’s daily, monthly, and annual performance using easy-to-understand diagrams and graphs.

The yellow bars represent the electrical production of the solar panels, while the blue bars represent household consumption.


Consumption Monitoring

Consumption monitoring, a new feature from SunPower, clearly shows your household’s electrical consumption, side by side with your system’s electricity production.  With the online NET meter, you do not need to wait for your electricity bill to see if your system is over- or under-producing.  Consumption monitoring allows you to track electrical use patterns and see when you use the most energy, which can be a tool for adjusting your personal electricity usage.

Assure Optimal Performance

Performance monitoring insures that unforeseen problems will not go undetected. Monitoring your system enables us to quickly assess if your system is down or under-performing due to solar panel shading, excessive accumulation of dust, or a possible component glitch. If TFS detects a problem, we immediately take action to reduce any system down time.

Solar Savings

Easily understand the financial benefits of your solar electric system by tracking how much you have saved over the lifetime of your system.  Also, you can use performance monitoring to further reduce your monthly electric bills by assessing your household’s energy use and optimizing net metering.

Quantify Your Environmental Impact

Using clear dynamic graphs and charts, performance monitoring tells you exactly how much your system is helping to reduce your carbon footprint by displaying the pollutants your PV system is offsetting. This makes it easy for you, your family, and friends to understand the environmental benefits of your system.

History & Trends

Easily view long-term trends in energy production and usage patterns under various times of day and year. You can even compare daily, monthly, or annual information.
