516-837-3459You made the investment of installing a solar panel system on your home or business, but now you’re unsure of what to do to maintain your system. How can you make sure your solar system is operating as efficiently as possible? Here are a few easy and recommended ways to help you with your solar panel maintenance and care.
What Maintenance is Required for Solar Panels?
Solar photovoltaic systems commonly known as solar panel systems are typically made from tempered glass. SunPower panels are extremely durable and designed to withstand extreme weather conditions. So whether you’re living somewhere that experiences heavy snow and rain, high wind, heat, or freezing temperatures, your solar panel system will be able to function and handle the climate. There are very few harsh weather conditions in which your solar panel system can be affected.
Ironically, the most common weather condition to affect your solar panel system is high heat, which can affect the operating efficiency of the panels. During high heat days over 90 degrees, solar panels may lose a small amount of efficiency, but this is only temporary and won’t have any lasting effects on your overall system. This is easily mitigated by installing the solar panel system a few inches above the roof, or above the ground, to enable air circulation under and around the panels. This helps keep the panels cool and the efficiency level up!
How to Clean SunPower Solar Panels
As a homeowner it is important to check your app frequently to ensure that your panels are producing energy as expected. One part of maintaining solar panels is making sure your solar panels are kept clean. A light rain shower could be enough to wash away light debris such as leaves, dirt, dust, and animal droppings. On Long Island and in New York City we get enough precipitation to keep panels clean naturally. However, if you notice that your panels are dirtier than expected and it is affecting your production for extended periods of time you can request a panel cleaning service from your installer.
It is never recommended that you climb on your roof and brush off debris on solar panels. Any accidental damage caused during cleaning would not be covered under a warranty. Since the panels have an anti-reflective coating you must also be careful not to wash your panels with harsh chemicals as they may damage the solar panels and cause a decrease in reflective efficiency. Reflective efficiency is when more light is captured and converted into energy, reducing the amount of light that bounces away.
Servicing Solar Panels During Winter Months
In the winter months, snowfall will typically melt and slide off your panels on its own and will require no maintenance at all. Using any type of scraper or brush can scratch and damage the panels, and using hot water to melt snow can do much more harm than good. Since the panels are made from tempered glass, using hot water to melt the snow can result in cracks in the panels, so you should always let the snow melt off naturally. A reputable installer may recommend adding snow guards as an added safety measure if you have concerns about snow sliding off of your panels all at once.
Solar Maintenance: How to Know When It’s Needed
The best way to know if your solar panel system might need maintenance is to check your system monitor. Solar system monitors report electrical output and can inform an owner when maintenance may be needed. Checking your production report consistently will help let you know right away if your system is in full operation or has run into an issue that requires attention. If after checking the monitoring app and something seems off, call your installer’s service department. They can help you determine if there is a technical issue with a panel and can diagnose and repair the system quickly.
How to Repair or Replace Solar Panels
Once connected, it’s critical to actively monitor your system’s production online or via your monitoring app. If you notice that your panels seem to be underperforming, it’s best to follow your installer’s guidance on troubleshooting. Most frequently, production issues can be attributed to loss of internet connection. If, after troubleshooting independently, you continue to experience issues you should reach out to your installer for assistance. Never attempt to make repairs or replace parts yourself, as this can void your system’s warranty.
Removing and Reinstalling Solar Panels
It may be necessary to remove and reinstall part or all of your system for reasons not known at the time of the initial installation (ie: roof replacement, siding replacement, house raising). In these unlikely situations, our service department (mailto:service@empower-solar.com) is available to provide you a quote on the costs associated with your particular situation. We can work with your contractors and your timeline to provide the most convenient reinstallation services to you.
Solar Panel Warranties: SunPower Warranty
The key to worry-free maintenance is a solid solar panel warranty. Before going solar, you will want to make sure you are doing your homework, reading reviews, asking questions about solar panel warranties, and making sure you are protected if a maintenance issue does occur. The average lifespan of a solar panel system is about 25-30 years, so you want to ensure you are protected for as long as possible.
A SunPower warranty is broken down into a few parts; a complete system warranty and a complete service warranty. The complete system warranty offers the most comprehensive coverage on the market covering your whole system including the panels, microinverters, racking system and even power production for 25 years, as well as a 10 year warranty on monitoring hardware. In most conventional solar warranties, each part is made and warranted by a different manufacturer, who typically only offer 10 year warranties for the parts. The SunPower complete service warranty covers any issues with your system, and includes an easy process so there is no need for receipts, proof of purchase or written claims.
SunPower will send a certified installation contractor to fix the issue and cover the cost of labor, shipping and parts for 25 years. SunPower will also include a workmanship warranty to cover any accidental damage caused by workmanship errors during installation. The conventional solar warranties will make you provide the original proof of purchase, submit a claim in writing, and ask you to pay to ship and package parts, both new and defective.
Importance of Solar Panel Maintenance and Care
When it comes to solar maintenance, it’s best to first choose a product that is proven to work well over long periods of time. Then choose a company that has a long history and a proven good-standing track record for servicing their clients. Proper panel installation is crucial to maximize solar power output, and ongoing maintenance ensures that panels meet energy production targets. Emphasizing these aspects can significantly enhance solar panel performance and longevity.
If you suspect a maintenance issue, call your service department! When your installer takes the safety of both their team, their solar systems, and their clients seriously, you can rest assured that your solar system will always perform at its peak efficiency.
