Solar Panel Inspection Checklist

Signs Stating The Solar Panels Need Inspection

• A significant reduction in the amount of energy that the solar panels will produce.


• Presence of dirt and or any other form of debris on the surface of the panel.


• This is in the form of abrasions on the surface of the panels or even small holes that are evident on the panels.


• Entries made on inverter which are the messages that appear in case of an error.


• High electricity bills while their weather remained consistently sunny.


• In Addition, an unidentified sound emanated from the inverter.


• Damage in the individual wires or connections especially those that are exposed to mechanical stress.


• Shading from new obstacles such as trees that may grow in future and block the light.


• Presence of water and or moisture at the edges of insulation on the ceiling and wall panels.


• Signs of discolouration or ‘hot spots’ that are visible on the surface of the panels.

Tools Required For Solar Panel Inspection

• Multimeter for measuring the electrical output as well as the connections.


• Thermal imaging camera for scanning to point out the hot spots and thermal problems.


• Pointer type device for determining the intensity of the sunlight.


• Things such as soft brushes, microfiber cloths and mild detergent should be used in cleaning.


• Tightening and securing of screws and bolts call for a screwdriver and wrench set.


• Personal protective equipment; safety harness and ropes to access the roof among other safety measures.


• Camera or any smartphone which will be used to capture any problems encountered.


• Insulation resistance tester to adequately check on electrical insulation difficulties.


• UV flashlight to identify any UV damage or crack.


• Rooftop access equipment is designed to facilitate safe access to rooftop panels.

Safety Measures For DIY Solar Panel Inspection

• Always switch off the solar panel system before inspection.


• Wear non-conductive gloves for protection against electrical shock.


• Employ a ladder that is stable and must be well placed on firm ground.


• Wear a harness on rooftops.


• Avoid inspecting during wet or windy weather.


• Be aware of and avoid live wires and electrical components.


• Use insulated tools to reduce the possibility of electrical contact.


• Always work where someone is available nearby in case an emergency should occur.


• Wear slip-resistant shoes to provide better traction when working on the roof.


• Be aware of sharp edges and corners on the panels and mounting hardware.

Benefits Of Solar Panel Inspection

• Helps lengthen the period it takes for your solar panel system to deteriorate.


• Has the ability to identify and avoid problems that might occur in future.


• This keeps safety by identifying any electrical danger chances and taking the necessary measures in eradicating the same.


• Preserve the aspect of panels to avoid indirect impacts like accumulation of dust and other materials.


• Ensures that there is maximum return on the investment by maintaining an optimum performance.


• Comes in handy in ensuring that all the warranty needs are met in the right manner.


• Improves dependability and stableness of the total system.


• It minimizes the chances that you will have to incur huge expenses in doing major repairs or even replacements.


• Ensures that you have less fluctuating costs of electricity hence paying much lesser amounts of money in your electric bills.

Regular inspections are vital to manage your home solar system's efficiency. Solar panel cleaners ensure your panels are dirt-free, improving energy output. Learn why cleaning panels is essential for system longevity, and understand the cost of cleaning services. Contact professional solar panel installers for optimal care and maintenance.
