A properly installation solar system requires few Solar panel maintenance. However the following maintenance tips you should keep in mind to keep your solar system in good shape.
Solar Panel Maintenance tips
A solar energy system requires few maintenance once it has been installed properly.A quality solar system can easily last over 15 years. In fact, solar panels carry a performance warranty of 25 years. With the right care you will be guaranteed of a steady and maximized output over a long period of time.[caption id="attachment_4951" align="aligncenter" width="515"] Solar panel maintenance - cleaning of solar panels[/caption]The following solar panel maintenance tips are recommended:
Solar panel cleaning
Cleaning of the solar panels is easy but labor intensive. It ensures that the solar cells are unobstructed and receive the maximum amount of insolation.Clean solar panels are important to maximize the panel’s energy output.Cleaning the glass on the panels is a simple procedure that can be carried out as often as required depending on how much dirt is accumulating. To clean panels, you can use a soft cloth or wash rag and biodegradable soap.If you are only dealing with dust you can run a hose pipe with water over the panels.
Shading is one of the things you already avoid when you do a proper site analysis during pre-installation.Once the panels have been mounted, you need to ensure shades do not come up such as new towering trees, as this will decrease the amount of energy produced by the system.You do not necessarily have to cut down trees but you can trim them to ensure the panels are not shaded.[caption id="attachment_4952" align="aligncenter" width="582"] Solar panel maintenance - ground installation cleaning[/caption]
Monitor the solar system
The only way to detect a problem in the system is to monitor its performance through daily, monthly, quarterly and annual checks.
Daily solar panel maintenance
Daily checks should involve monitoring the inverter display to ensure that it is working correctly and that the green light is on, failure to which you should refer to the manual.Also, keep a daily record of the system’s output to be able to monitor performance over a long period of time. Most modern inverter and their monitoring software will do this automatically for you.
Monthly and quarterly solar panel maintenance
Monthly and quarterly maintenance checks involve checking the cleanliness of the panels, and accumulation of any dust and debris under and around the PV array.Annual maintenance checks are more detailed and should involve a thorough checkup of the entire system to ascertain that it is working correctly.
Annual solar panel maintenance
Some of the annual maintenance services for solar systems include:
Performing a general performance check of the system by reviewing the daily performance data to detect any major changes in output
Checking the solar panels to ensure that they are clean, free of fractures, scratches, corrosion, moisture penetration and browning.
Cabling should be checked to ensure it is secure and the voltage of strings is within the stipulated tolerance.
Checking the mounting hardware to ensure it is in good condition and ensuring the earth connection is continuous.
Checking of junction boxes to ensure there is no water accumulation and that the integrity of lid seals, connections and clamping devices is intact.
Checking of breakers for any damage, and to verify that the isolation devices are working correctly
Checking of fuse boxes for water damage and resistive joints on connections
Inspecting the inverters to assess any damage, checking for any resistive joints on connections and verifying the DC voltage coming into the inverter.
