Solar Panel Maintenance

 
While it is true that solar panels are supposed to be in the open air, not every location will ensure optimum efficiency or ensure they retain as much energy from the sun as possible. Plus even though they are quite similar to windows, that does not mean that they should be cleaned the same way. Cleaning a window pane with some soap, clean water and a dirty rag is one thing, but these items might damage the panels irreparably if you try them on them. Professionals know the techniques and materials to use and that can ensure this does not happen during the cleaning process.

Overtime, the panels can accumulate dust, pollen, dirt and get ‘clouded’ and inefficient. In fact, there is a 10 to 15% drop in efficiency in solar panels that are allowed to accumulate dust and dirt. To make sure that does not happen with yours the panels need to undergo solar panel maintenance or be cleaned thoroughly. Hiring professionals to do it regularly and on schedule will ensure your solar panels remain undamaged and functional for years to come.
 

Why solar panel maintenance and cleaning should be left to professionals

Even though cleaning panels might look easy even the slightest slipup can damage them irreparably resulting in costly repairs. The apparent danger lies in the fact that these panels are usually installed on roofs that are several feet off the ground. A fall from that height will kill any normal person and electrocution is also a clear and present danger. Professional installers know what they are doing and what they should be wary of during the installation process.

Panels are usually scheduled for cleaning three times a year; once during the spring and once after the rainy season has gone and once before winter sets in. Hiring professionals to do it will ensure your solar panels remain functional for more than 2 decades.

Once the panels have been installed your installer will leave a detailed list of maintenance checks which need to be carried out regularly to ensure the panels are working fine. The details should also contain information on main inverter fault signals along with a guide that can be used to troubleshoot minor issues. In other words they know the importance of regular solar panel maintenance and will ensure you do as well. However, asking them to come and clean the panels will be your responsibility.
Some maintenance and installers will provide a package or a complete solar panel maintenance contract so you can be rest assured that your panels will be taken care of after installation. The system will probably cover the following things:

• Inspection of the panels from all angles
• Checks on the inverter, meter and other components of the system
• Analysis of energy production or generation
• Inspection of the condition of the roof
• Voltage and current check.

Also keep in mind that if the panels need to be looked over from all angles, it would be better to leave it to the professionals. On the other hand, if the panels are on the ground and you cannot afford to hire them or do not have a contract you can try to do a DIY job at your own peril.

Nevertheless it is always wiser to trust the professionals when it comes to solar panel maintenance and cleaning. The system does not come cheap after all but always check out reviews before hiring someone. Professional panel installers usually offer cleaning services so you can check their references out from anyone who has ever benefited from their expertise.
