Solar Panels Not Working? 10 Common Problems & How to Fix Them


 Solar panels have become popular for Australian homeowners seeking sustainable and cost-effective energy solutions. However, like any technology, they can encounter issues that impede performance. Understanding common problems and their solutions can help maintain optimal functionality and extend the lifespan of your solar energy system.

Common Issues Affecting Solar Panel Performance

1. Dirt and Debris Accumulation

Over time, solar panels can accumulate dust, bird droppings, leaves, and other debris, especially in Australia’s diverse climate. This buildup can obstruct sunlight, reducing the panels’ efficiency.

Solution: Regular cleaning is essential. It’s advisable to schedule cleaning at least twice a year, or more frequently in areas prone to heavy dust or bird activity. Ensure safety measures are in place or consider hiring professionals for the task.

2. Shading Issues

Shading from nearby trees, buildings, or other structures can significantly impact solar panel performance. Even partial shading can lead to disproportionate drops in energy production.

Solution: Conduct a site assessment to identify potential shading sources. Trimming overhanging branches or repositioning movable obstructions can mitigate shading. For unavoidable shading, installing microinverters or power optimizers can help maintain efficiency.

3. Inverter Malfunctions

The inverter is a critical component that converts the direct current (DC) solar panels produce into alternating current (AC) used in homes. Inverter faults are a common cause of system underperformance.

Solution: Regularly inspect the inverter for error messages or fault indicators. If issues are detected, consult a certified technician to diagnose and repair or replace the inverter as necessary.

How to Know the Right Solar Panel Direction for My House?

Image
Before five to six years, all   CEC accredited solar installers   in Australia used to suggest installing solar panels facing north direction. This was assumed because of high feed-in tariff availability. However, things have become pretty intricate now. To maximize the use of solar energy than grid power has become necessary. Therefore, the whole focus of the solar panel facing depends on maximizing self consumption. When you surf for solar panel installers near me, you need to ensure you only connect with  CEC accredited solar installers . They will suggest the best direction for solar panels to face. However, if you want to be sure or if you are using some other way of installation, read on to know which direction is right to face for your solar panels: 1. East East-facing solar panels give the best output during the morning. It produces around 12% reduced energy compared to north-facing. The maximum energy it produces in the morning and the least in the afternoon. Rea...

Bifacial Solar Panels vs. Monocrystalline – Which To Choose?

Image
As solar technology continues to evolve, homeowners and businesses are faced with multiple options when selecting the right solar panels. Two of the most popular choices in Australia are bifacial solar panels and monocrystalline solar panels. But which one is the best for you? Let’s get into bifacial vs Monocrystalline solar panels. What Are Monocrystalline Solar Panels? Monocrystalline solar panels are made from a single silicon crystal, giving them a sleek black appearance and high efficiency. These panels are widely used in residential and commercial solar installations due to their superior performance and longevity. Advantages of Monocrystalline Panels High Efficiency: Typically ranges from 18% to 22%, making them one of the most efficient solar panel types available. Space-Saving: Generates more electricity per square meter, ideal for areas with limited roof space. Durability & Longevity: Offers a lifespan of 25 years or more, with minimal degradation over time. Better Perfo...
