Solar panels are an excellent option for those who are concerned about their environmental footprint and their electricity bill costs.
The installation of solar panels is only the beginning, though. Constant evaluation is required to guarantee they are producing the expected amount of energy.
By reading this article, you learn more about solar panel performance monitoring and how to pick the best monitoring system for your needs.
The Importance Of Monitoring Solar Panel Performance
The efficiency of your PV system may be tracked and reported on with the help of a solar monitoring system. It covers how much energy your home uses and produces, how to maximise your energy efficiency, and what to do if your solar panels are damaged.
You should monitor your setup to know if your solar panels are performing at peak efficiency.
For example, you can see if there have been any noteworthy shifts in performance with a monitoring system.
Most solar energy providers will install monitoring hardware and special software to connect it to the inverter.
Currently, the most common method is through applications, which are built into most of your devices and can use cellular data on a mobile phone or tablet, keeping your data accessible even if your Wi-Fi goes down.
During regular business hours, you can also use a PC with Wi-Fi.
While solar panels are extremely long-lasting and need little in the way of upkeep, other system components could suffer damage or malfunction. Maintaining peak system performance requires regular monitoring.
What Are Solar Panel System Components?
A solar panel system consists of six major components: the panels themselves, the inverter, the racking, the optimisers, the electrical metre in the house, and the energy monitoring equipment.
Battery storage is the seventh component of a solar energy system and is not necessary for its operation but can be useful in an emergency. Let’s have a look at these solar components.
Modules
Solar panels use the sun’s rays to create electricity. Therefore, the choice of the panel has a significant bearing on the panel’s visual appeal and functional efficiency.
Inverter
While your home uses alternating current (AC), solar panels generate direct current (DC).
The “inverter” that comes with your solar power system is the brain that converts DC into AC power for your home’s appliances.
The inverter manages the power from the panels and ensures the correct voltage flows into your home or back to the grid, among other critical tasks.
Racking
The mounting or racking system for solar panels keeps them in place. Racking for a roof-mounted system might be installed at the time of building or later on for an existing home.
Optimisers
Each solar panel has an optimiser attached to its rear to increase its output when another panel is blocking the sun or covered in bird faeces.
They aid performance monitoring by revealing each panel’s operational status, facilitating the detection and resolution of manufacturing faults. Power is cut off automatically by optimisers when the system fails.
Meter
After installing your solar panels, the utility company will replace your current metre with a more advanced bi-directional one.
The new metre will ensure you receive full credit for the solar power you export to the grid.
Energy Monitoring
Finally, one of the most crucial parts is keeping an eye on the sun.
You can see how much electricity your panels produce and how much energy you use thanks to the monitoring systems that are standard with most installations.
Batteries
Your home’s batteries can store the excess energy your solar system generates for later use.
With battery storage, you can power more of your home with clean solar energy during daylight hours or have energy security to keep the lights on during power outages.
What Is The Process Of Solar Monitoring?
The inverter for a solar energy system usually also incorporates a monitoring system.
While standalone modules are an option, all monitoring tools communicate with the inverters in the system.
The solar monitoring system records production and power level data when the inverter transforms DC (Direct Current) from the solar panels into AC (Alternating Current).
This information is transmitted to a cloud-based monitoring system and associated apps or platforms.
Then you can use your phone or another device to learn more about the solar system around you. It is also possible to set up monitoring equipment right there on the premises.
If you need access to data stored in the cloud but don’t have Wi-Fi (or other internet connectivity), a system with cellular capabilities can be set up. Some solar panel monitoring systems, however, require constant access to Wi-Fi.
Different Types Of Solar Panels Performance Monitoring
Several readily available tools can track solar energy generation, consumption, and efficiency. The following are examples of solar power monitoring techniques:
Real-Time Monitoring Or Pc
Free monitoring software is available for download from the manufacturer’s website for installation on a personal computer.
Then, either use Bluetooth to link your computer to the Inverter or connect the two devices using a CAT5 cable.
This is a low-cost, effective solution when data logging is a priority.
Mobile Connection Monitoring
You can use your phone’s Bluetooth connection to access the data and modify the inverter’s profile settings.
This system enables solar energy monitoring without the need for wiring.
Additionally, data can be seen remotely via an internet connection or text messages (SMS), depending on your preferences and the services you have enabled.
Monitoring Of Displays For Unit Connections
This may have been one of the first methods to track information from a solar array.
Using this technology, data can be gathered from a single or more inverter networked using Bluetooth or CAT5 cable and then displayed on a central device.
This technique also gathers data via Bluetooth or a CAT5 cable.
Monitoring Internet-Based
Simply inserting a card into your inverter and linking it to a router will get the data online and into the public domain.
The information is then made available to the user remotely via an internet portal or specialised website.
This approach has certain benefits, but the inverter and card will have some added costs.
The daily operations, outputs, and consumption of solar panels can be tracked using monitoring devices. It also aids in revealing where energy is being wasted and if the investment made was worthwhile.
Functions Of Pv System Tracking Software
Platforms for PV monitoring may or may not have the following capabilities:
Analyses And Calculations
Solar photovoltaic (PV) system description and ambient factors input into a computer model to provide data interpretation.
Performance Measurement Reports
Reports on platform availability and performance ratio are useful features of monitoring tools. Reports can be made available on platforms’ websites or emailed to stakeholders.
Financial Calculations
Platforms can estimate economic revenue or utility cost savings connected with the recorded energy delivery based on the time of day and seasonal fluctuation in utility rates. In addition, the downtime or decreased output cost could also be factored into economic evaluations.
Alarms And Errors
Operators can be alerted to any errors or abnormalities via monitoring tools. In addition, email and SMS messages can be sent as platform alerts.
Maintenance Tickets Issued And Monitored
Users of a monitoring platform can create trouble tickets to report issues and monitor their progress as they are resolved.
Connect To A Larger Or More Useful System.
Platforms for monitoring can send information back to the utility provider when necessary, and they can also receive signals from the utility to adjust the PV system’s parameters as needed.
Methods To Increase Solar Panel Efficiency
Maintaining Solar Panels is minimal for a well-installed solar system. However, here are a few preventative care tips to keep in mind for your solar array’s longevity.
After a solar energy system has been established correctly, there is little to do to keep it running efficiently.
An efficient solar panel system should last for at least 15 years.
Solar panels have a 25-year performance guarantee. With proper maintenance, you can count on a high productivity rate for a long time.
Maintenance Of Solar Panels
Cleaning solar panels is a simple yet time-consuming process.
It makes sure the solar cells get plenty of light without any obstructions. In addition, solar panels produce more electricity if they are kept clean.
The glass on the panels may be easily cleaned and should be done as often as necessary to prevent grime buildup.
First, use a gentle cloth, washrag, and environmentally-friendly soap to clean the panels. Then, spray dust from the panels with water from a hose to remove dust from the panels.
Keep The Light In!
If you thoroughly analyse the site before installing it, you won’t have to worry about shading.
However, after installation, you’ll want to look for new shade sources like tall trees that could cut into the panels’ output.
Trees can be trimmed rather than removed to prevent the shading of the panels.
Keep An Eye On Our Solar System
Daily, monthly, quarterly, and yearly checks are the only method to identify a systemic issue.
Regular Solar Panel Cleaning
In order to make sure the inverter is functioning properly, it is recommended to check the display every day to see if the green light is on.
In addition, to track performance over time, keeping a log of the system’s output daily is helpful. The monitoring software on the most up-to-date inverters will accomplish this automatically.
Solar Panel Checkups Once Every Month And Every Three Months
Monthly and quarterly inspections should include looking for dust and debris under and around the PV array and making sure the panels themselves are clean.
The complete system should be checked for appropriate operation once a year as part of routine maintenance.
Regular Solar Panel Inspections
- Annual maintenance for solar systems typically consists of the following:
- Reviewing the system’s daily performance statistics in search of significant shifts in output is a good first step in performing a general performance assessment.
- Verifying that the solar panels have not been damaged in any way (this includes cracks, scratches, corrosion, moisture penetration, or browning) and that they are clean.
- It is important to double-verify the wiring and ensure the string voltage is within the acceptable range.
- Verifying the mounting hardware’s integrity and the earth connection’s continuity.
- Inspecting junction boxes for signs of water buildup and faulty lid seals, connections, or clamping devices.
- Inspecting circuit breakers for wear and making sure isolation devices are functioning properly.
- Fuse boxes must be inspected for water damage and faulty solder joints.
- Verifying the DC voltage entering the inverter, looking for signs of damage, and testing for resistive joints on connections.
Conclusion
Solar panels are a great choice for people who care about the environment and their energy bills.
However, they must be monitored on a regular basis to make sure they are generating the desired amount of energy.
