5 Things to Check on Your Solar System Each Month to Keep it Running Smoothly
With their few moving parts and limited maintenance needs, solar panels can typically last years without experiencing any issues. However, in order to keep them working at peak performance and to keep from having any major maintenance issues, it is important to give them preventative care throughout the year. Here are the top five things you should be doing each month in order to keep your solar panels working the best they can.
Watch for dirt and debris buildup
Being sure to keep your solar panels free from any obstructions helps ensure that you are maximizing the efficiency of your system. You should be sure to remove snow, dust, and leaves from your panels on a monthly basis to keep your system running smoothly. However, if your system is installed in a way that could put you at risk of a fall, do not attempt to clean them yourself. Many solar systems are mounted low enough that cleaning is possible from the ground using a land-handled broom. For panels mounted higher, your installer will likely have a solar panel cleanings service to recommend. Having a professional come to clean your panels can help ensure that your panels receive a thorough cleaning and that they will not be damaged in the process.
Inspect your rack and roof penetrations
Solar panels are mounted to your roof with a rack. This rack carries the weight of the panels and holds them to the roof using several sturdy bolt penetrations. A monthly visual inspection is a great way to catch any potential drainage or structural issues before they become serious. While it can be tough to identify drainage issues from the outside, they should be visible from the inside in the form of leaks. You should do a monthly visual inspection of your attic space to see if you notice any leaks under the areas where your panels are mounted.
Missing bolts can also be an indicator of impending rack failure. Panels can loosen in their mounts over time due to snow and wind, so if you do find a potential issue contact your solar panel installer to inspect and repair the rack.
Examine potential corrosion
Solar systems are made with durable and long lasting components, allowing them to produce energy for twenty-five years or more. Your rack and panels will likely be made from corrosion-resistant materials, but after a long period of time corrosion could develop and compromise the strength of your system components. Doing a visual check for corrosion once a month helps to give you the opportunity to address any issues before they become serious.
Check for broken glass
The silicon wafers inside your solar panels are covered by extremely durable tempered glass. This glass is rated to withstand bad weather conditions, even hair storms. However, fallen tree branches or an especially bad storm can result in broken panels. If you notice any broken panels, you should call your solar installer immediately.
Look for faulty wiring
All solar arrays contain an inverter, which converts the direct current the panels produce into the alternating current used in your homes electrical system. In many cases, each panel is wired in a series to one single inverter which creates many potential points of failure.
Faulty wiring can be difficult to diagnose. There will sometimes be a visual indication such as a snapped wire or a broken connection, but this may not always be the case. However, there are two ways to diagnose faulty wiring. Many of the new systems come with real-time production tracking, so if your system uses this technology you can check it to see if it is under-performing. If you have an older system that does not use this technology, you can use your monthly bill as an indicator of any potential issues. If you notice a problem, do not attempt to repair it yourself, but instead be sure to call your installer.
