Solar Panel Systems Maintenance & Warranties

Updated: Sep 17, 2019

Worried about solar panels? Solar panel systems are incredibly durable and require little to no maintenance over their productive lifetime – which can span 25 years or more. In the event that something does go wrong, your solar panel system components have very long warranties that would cover replacement and repair costs.


Solar Panel Warranties


Solar panel manufacturers provide a range of warranties that guarantee you will have support and coverage in the unlikely event of an issue, such as falling tree branches.


Power output warranties guarantee that panel performance will not fall below a specified level over the term of the warranty (usually 25 years). For instance, a manufacturer might provide a warranty to guarantee that peak power output will not fall below 85% for 25 years.


Some manufacturers will also include an additional warranty that promises a higher output level over a shorter period of time. For instance, a secondary warranty might guarantee no less than 90% of initial power output for the first 10 years.


Panels typically come with a workmanship warranty that protects consumers against defective panel parts, generally for the first five years of operation. Inverters also come with warranties, usually for 10 years.


How To Maintain Solar Panels

Solar panels are made of tempered glass, so they are built to withstand hail and other rough weather. With the exception of tracking mounts, solar panel systems do not have movable parts, which cuts down on the possibility of any problems.


Any issues with solar panel performance are usually related to electricity production, which is why most installers recommend monitoring your system’s production. By paying attention to changes in production, you can identify and address issues proactively.


Generally, solar panels do not need to be cleaned. If you live somewhere where there is a lot of smog, dust, or dirt, you may see a dip in your production over time that can be remedied by cleaning your panels. If your panels are mounted on your roof, however, your best option is to hire a professional cleaning service rather than try to clean them yourself. Your installer will be able to recommend someone local to help you.


For your panels to be self-cleaning, they will need to be mounted at an angle of 10 degrees or more. If you have any doubts on this, you may contact Solar Era to assist you to solve your problems.
