In this blog, we’ll cover everything you need to know about solar panel maintenance and how to ensure your system is delivering optimal performance.

Why Is Solar Maintenance Important?

While solar panels are designed to be durable and low-maintenance, regular upkeep is essential to ensure they continue generating maximum energy. Even minor issues such as dirt, dust, or debris can reduce the efficiency of your system, which can lead to decreased energy production overtime.

Proper maintenance can help:‍

• Maximize energy production: Keep your panels clean and functioning optimally to produce as much energy as possible.
• Extend the lifespan of your system: Solar panels are an investment that should last 25-30 years, so maintaining them properly can ensure you get the most out of your system.
• Avoid costly repairs: Catching small issues early can prevent them from developing into bigger, more expensive problems.

What Maintenance Do Solar Panels Require?

1. Cleaning the Panels The most basic form of solar panel maintenance is cleaning. Over time, dust, leaves, bird droppings, and other debris can accumulate on the surface of your panels, blocking sunlight and reducing their efficiency. In some areas, like rural or coastal areas in Taranaki, environmental factors such as dust or salt can cause additional buildup.

How often should you clean your solar panels? The frequency depends on the location and weather conditions, but as a general rule, it’s a good idea to clean them at least once or twice a year. If you live in a particularly dusty area or near trees, you may need to clean them more frequently. Some signs that your panels need cleaning include:

• Reduced energy output
• Visible dirt or debris on the panels
• A noticeable difference in energy production during sunny weather compared to previouse month

Pro Tip: It’s always best to hire a professional to clean your panels to avoid damage or voiding any warranties. If you decide to clean them yourself, use soft brushes or cloths and avoid using harsh chemicals.

2. Checking for Damage: Regularly inspecting your solar panels is key to ensuring they’re functioning properly. Solar panels are built to withstand harsh weather conditions, but they’re not immune to damage from storms, hail, or falling branches. Look out for:

• Cracks or chips in the panels
• Loose or damaged wiring
• Any visible discolouration or marks that could indicate an internal issue

It’s important to check both the panels themselves and the wiring to ensure everything is intact. If you notice any damage, contact a professional installer immediately to get it repaired.

3. Monitoring System Performance Many modern solar panel systems come with monitoring systems that allow you to track your system’s performance. This is an easy way to identify potential issues early. A drop in energy production could indicate a problem, such as shading, dirt buildup, or a malfunctioning component.

Keeping an eye on the system’s performance through monitoring tools can help you spot any sudden drops in power output, ensuring that any issues are addressed promptly. Your installer can assist you insetting up and interpreting this monitoring system so you can keep track of how your system is performing year-round.

4. Inspecting the Inverter The inverter is the heart of your solar system, converting the DC electricity produced by the panels into AC electricity for your home. It's essential to keep the inverter in good working order, as any issues here can affect your overall system’s efficiency.

Inverters typically have a lifespan of 10-15 years, and although they don’t require much maintenance, they do need to be inspected regularly. Some signs that your inverter may need attention include:

• Error messages or flashing lights
• A drop in energy production (even when theres enouth sunlight)
• Inverter making strange noises or overheating

If you notice any of these signs, it's important to contact a professionals such as RPG Solutions to have it assessed and repaired.

5. Clearing Obstructions: Over time, natural elements like tree branches, leaves, or vines can grow around your panels or even block sunlight from reaching them. It’s essential to clear any obstructions regularly, especially if you have large trees nearby. This will help prevent shading, which can significantly reduce the performance of your system.
6. Maintaining  the Battery Storage (If Applicable) Many solar systems are paired with battery storage to store excess energy for use during cloudy days or at night. If you have a battery, it’s essential to perform regular checks on the battery’s health. Over time, batteries can degrade and may need to be replaced. Signs that your battery may need attention include

• The battery is not holding a charge like it used to
• Frequent charging and discharging cycles
• Warning lights on the battery system

Regular maintenance of the battery system will ensure that you continue to benefit from stored energy, especially during power outages orperiods of low sunlight.

When Should You Call a Professional?

While solar panels are low maintenance, there are times when it's best to call in a professional. Here are a few situations when you should reach out to a solar specialist:

• If you notice a significant drop in energy production that claening or simple adjustments wont fix
• If your inverter is showing error messages or behaving abnormally
• If your system is more than 5-10 years old, it may need a full inspection to ensure all components are still functioning well
• After severe weather events, such as storms, hail, or strong winds, which may cause physical damage to your panels or wiring
