Why is my solar energy production lower than expected?

The generation of solar energy can fall short of expectations due to various factors. Addressing these factors can optimise and increase the output of your solar system.

First, solar panels rarely achieve their nameplate wattage under real-world conditions. This rating is based on ideal laboratory settings that typically differ from the environmental conditions of rooftop installations.

Sunlight availability is a primary factor in solar energy production. Any reduction in sunlight due to weather patterns, for example via rain around Barandua (Victoria)  or such as prolonged periods of cloud cover in the NSW/Victorian border region, directly impacts output. Weather-induced fluctuations are expected, but they should be considered when setting energy expectations.

The physical arrangement of the solar system is equally critical. The tilt and orientation of solar panels, along with geographical latitude and local climate, can significantly impact energy production. Improper tilt or orientation can reduce sunlight capture and, consequently, energy production.

Temperature plays a vital role in the efficiency of solar panels. Solar cells typically operate better at lower temperatures. High temperatures can lead to a decrease in voltage output, despite a slight increase in current, reducing the system’s overall efficiency.

In extreme heat, solar panels can overheat, not only decreasing output but also potentially damaging cells and shortening the system’s lifespan. For instance, during heatwaves, solar panels can reach 85 degrees Celsius plus, potentially reducing power output by up to 20% compared to optimal conditions around 25 degrees Celsius.

Soiling is another crucial consideration. Dirt, dust, and other debris that accumulate on the surface of solar panels can block sunlight and significantly reduce efficiency. Regular cleaning is essential, especially in dusty areas or places where bird droppings and pollen are common. That’s why we recommend a regular system health check. 

Physical damage to the panels, such as a cracked glass cover, can also cause a drop in energy production, and eventually will lead to a complete panel failure.

Since solar panels are usually connected in a series, damage to one panel can affect the efficiency of the entire system. Regular inspections and maintenance are crucial to ensure that all panels are in good condition and to replace or repair any damaged ones promptly.

Also one would have to consider the inverter.Usually these inverters receive 2 or 3 strings of solar panels, and maybe one of the string connection’s was interrupted or faulty plugs causing issues.

In summary, understanding the nuances of solar panel nameplate wattage, the dependency on consistent sunlight, the importance of weather patterns, the optimal setup of the solar array, the influence of temperature, and issues like soiling and physical damage are all essential for diagnosing and improving the performance of a solar energy system.

Regular monitoring and maintenance can help mitigate many of these issues, ensuring that the system operates as efficiently as possible and maximising your solar investment.

What should I do if my solar panels are covered in dirt or bird droppings?

In such an instance  your panels require to be cleaned. Cleaning solar panels can be a dangerous task, as they are often located on relative steep roofs.

Climbing onto the roof and maneuvering around solar panels can pose fall risks and potential electrical hazards. Additionally, improper cleaning methods can damage the panels, reducing their lifespan and efficiency.

At Solar Integrity, we understand the importance of safe and effective solar panel cleaning. Our experienced technicians are equipped with the proper tools and expertise to handle the job safely and efficiently.

  1. Safety first: Before cleaning, we prioritise safety by ensuring secure access to the panels using sturdy ladders and harness systems. If the panels are out of reach or you feel uncomfortable with heights, our team will gladly take over.

  2. System shutdown: We turn off your solar system to eliminate electrical hazards while cleaning. This involves switching off the inverter and AC/DC isolators.

  3. Dry cleaning first: For loose dirt and dust, we employ a dry cleaning method using a soft brush or a leaf blower to remove debris without water. This approach is quick and allows us to move to step 2 involving water.

  4. Soft cloth and mild detergent: For stubborn grime like bird droppings, we use a soft cloth or sponge dipped in a mild detergent solution and lukewarm water. We avoid abrasive materials or harsh chemicals that could scratch or damage the panels’ protective coatings.

  5. Gentle water rinse: If necessary, we gently rinse the panels with a water hose to remove persistent dirt. We strictly avoid high-pressure washers that could damage the panels cells, causing micro cracks.

  6. Squeegee drying: After washing, we use a squeegee to remove excess water, preventing mineral deposits and streaks from forming as the panels dry.

After the panel clean we might recommend regular maintenance and protective measures

  1. Regular cleaning schedule: Establish a regular cleaning schedule to prevent dirt and bird droppings from accumulating and affecting panel performance. The frequency depends on your local environment. Seasonal cleaning may suffice in some areas, while others may require more frequent cleaning.

  2. Bird deterrents: Install bird deterrents like spikes or nets to discourage birds from perching on or near the panels, minimising bird droppings.

  3. Tree trimming: Trim nearby trees to reduce the amount of leaves and debris falling onto the panels. This will also assist with overshadowing of panels.

  4. Performance monitoring: Keep an eye on your solar system’s output through its monitoring system. A noticeable drop in performance could indicate the need for cleaning, even if the panels don’t appear dirty from ground level.

Why is my inverter displaying an error code?

Your solar PV inverter may display an error code for various reasons. Usually error codes indicate a more serious issue , but in some instances can be an indication of an external issue such as grid voltage, and those  issues can disappear again.

Each inverter brand has its set of codes that can help diagnose issues. For Fronius inverters, common error codes range from grid voltage and frequency disturbances (codes 102 to 560), overcurrent and insulation faults (codes 301 to 502), inverter status notifications (codes 306 to 522), electrical connection issues (code 108), temperature issues (codes 304 to 517), and software issues (codes 431, 482, 743, 745)​​.

SMA inverters also have a comprehensive list of error codes that indicate everything from grid faults (codes 101 to 103, 202 to 205, 301 to 302), AC voltage issues (code 302), grid disconnection or frequency changes (codes 401, 404, 501, 601, 701), installation issues (codes 901, 1001, 1101, 1302, 1501), unstable operation or DC input problems (codes 3301 to 3303, 3401 to 3402, 3407), insulation failures (code 3501), overcurrent conditions (codes 3801 to 3802, 3805), start conditions not met (codes 3901 to 3902), self-diagnosis alerts (codes 6002 to 6412, 6501 to 6502, 6509), input defects (codes 6801 to 6802, 6901 to 6902), communication issues (codes 6701 to 6702, 7102 to 7106, 7110 to 7112), and updates or configuration errors (codes 7303 to 7356)​​.

For Sungrow inverters, the error codes are typically numerical and reflect issues like grid voltage and frequency disturbances (codes 002 to 015, 101 to 102), overcurrent faults (codes 006 to 007, 011 to 012, 021 to 022, 100, 202), electrical connection problems (codes 010, 028, 1029, 2084, 106), temperature-related issues (codes 036 to 037, 043, 070), and software compatibility (code 085)​​.

These error codes serve as a troubleshooting starting point. Many issues, such as grid voltage or frequency disturbances and overcurrent faults, can be temporary and may resolve on their own once the grid stabilises or the transient event passes.

However, persistent error codes or those indicating more serious issues like insulation faults, temperature extremes, or software problems may require technical assistance.

If you’re not confident in addressing these issues on your own, or if the error persists, it’s best to contact Solar Integrity for further assistance.

Regular maintenance and monitoring can help catch these issues early, reducing downtime and maintaining the efficiency of your solar PV system.

Why is my solar system not producing power during a sunny day?

A solar system that fails to produce power on a sunny day can be a frustrating experience.

If there are issues like this ,please contact us here at Solar Integrity for a call out to get you back into renewable power fast.

Technical issues with panels or inverter solution

  1. Faulty wiring: Loose or damaged wiring can disrupt the flow of electricity, preventing the inverter from receiving the power generated by the panels. This can include faulty connection plugs eg MC4s.

  2. Inverter failure: The inverter, which converts DC power from the panels to AC power for home use, may be malfunctioning due to a component failure or firmware issue.

  3. Micro-Inverter issues: If your system uses micro-inverters (on each panel), a faulty unit should not affect the output majorly, as this is one of the advantages of micro inverters, but if there is an issue with more than 1 unit, you do loose power and therefore money.

  4. Panel malfunction: Individual solar panels can also malfunction due to defects or damage, reducing or eliminating their power output.

Environmental factors and debris:

  1. Shading: Even during a sunny day, temporary shading from clouds, trees, or nearby structures can significantly reduce the power output of the PV system.

  2. Dirt and debris: Accumulation of dust, leaves, or bird droppings on the panels can obstruct sunlight, hindering their ability to generate electricity.

  3. Snow cover: While not really an issue in Albury-Wodonga , in colder climates, a thin layer of snow can cover the panels, even on sunny winter days, preventing them from receiving a lot of sunlight.

  4. Temperature effects: Excessive heat can reduce the efficiency of solar panels. Solar panels operate best within a specific temperature range and around 25 degrees Celsius is the best.

System configuration and maintenance issues:

  1. Improper installation: If the system was not installed correctly, with panels not oriented or tilted optimally, it can result in reduced power production.

  2. Maintenance neglect: Lack of regular maintenance can lead to the build-up of issues, such as dirt accumulation liken growing on panels, or component aging, that cumulatively reduce efficiency.

  3. Aging components: Over time, the efficiency of solar panels and other components can degrade naturally, leading to a decline in power output.

Electrical and grid issues:

  1. Grid outages: Sometimes, the problem isn’t with your solar setup but with the grid itself. In certain grid-tied systems, an outage can trigger an automatic shutdown of the inverter for safety reasons. Then sometimes when the issue is resolved the inverter still does not reconnect automatically and needs a “re-boot”.

  2. System overload: If the system is generating more power than it’s designed to handle, it may shut down to prevent damage to the system or the grid.

  3. Faulty metering: The meter that measures the electricity production might be malfunctioning, giving the impression of no production, even when the system is generating power.

  4. Energy management system problems: Software glitches or communication breakdowns within the energy management system can prevent the system from reporting production data correctly.

Safety features and regulations:

  1. Automatic shutdowns: Modern solar systems are equipped with safety features that may trigger an automatic shutdown in certain conditions, such as ground faults or overheating or elements such as the inverter.

  2. Line work or compliance: Utility companies may temporarily disconnect systems for maintenance or to ensure compliance with new regulations.

Financial and policy constraints:

  1. Net metering limits: In some areas, there might be limits on net metering, where the system stops delivering excess power to the grid once a certain threshold is reached.

Troubleshooting steps we  at Solar Integrity would undertake 

  1. Visual inspection: Check for obvious signs of damage or dirt on the panels, inverter, and wiring.

  2. Inverter display: Review the inverter display for error codes or warning lights that may indicate a specific issue.

For any of these issues Solar Integrity are only a phone call away.

Can I expand my existing solar system with more panels?

Many homeowners of an older and smaller solar PV system are considering expanding their existing systems to maximize energy savings. While this decision can be an excellent step towards energy independence, it’s crucial to approach it with careful consideration and thorough planning,.

In many instances the Australian Standards that governed the installation of the original system have changed.  This means the older solar system, while permitted to run in it’s existing form, would need to be upgraded if major improvements and expansions are planned.

We are Solar integrity can assist in this matter and we would follow the outlined steps.

Assessing your current system’s capacity

Before embarking on the expansion journey, it’s essential to evaluate the capabilities of your existing solar panel system. The inverter, the heart of the system that converts direct current (DC) from the panels into alternating current (AC) for household use, plays a pivotal role in determining the additional load it can handle.

If your current inverter is nearing its maximum capacity, upgrading to a larger inverter may be necessary to accommodate the new panels seamlessly.

Alternatively if the change to a different inverter requires also more costly changes to the system, for example all wires will need to be put in conduits (as per latest regulations), then it might be better to leave the existing system as is and add a 2nd PV array to the roof.

Roof space and structural integrity – the foundation of your expansion

Your roof, the foundation upon which your solar panels reside, plays a crucial role in determining the feasibility of expansion.

Ensure that your roof has sufficient space to accommodate the additional panels without compromising safety or aesthetics. Additionally, assess the structural integrity of the roof to ensure it can support the weight of the new panels, preventing potential damage or hazards.

Several factors influence the lifespan of a solar system:

  • Climate: Extreme weather conditions, such as high humidity or hail, can affect system durability.
  • Quality: Investing in high-quality components and professional installation can extend the system’s lifespan.
  • Maintenance: Regular maintenance, including panel cleaning and performance monitoring, is crucial for preserving system efficiency.

Preserving Your Solar System:

  • Installation: Ensure proper installation with sturdy mounting, adequate spacing, and high-quality materials to prevent premature wear.
  • Maintenance: Schedule regular panel cleaning and inspections to address debris buildup, loose connections, or panel damage.
  • Performance Monitoring: Utilize monitoring tools to track system performance and identify potential issues early.

When to Replace Your System:

While solar systems are designed to last for decades, replacement may be necessary. Signs indicating the need for replacement include significant performance decline, panel discolouration, or physical damage like cracks or hotspots.

A solar panel system typically lasts around 25 years with proper maintenance and care. By investing in quality components, adhering to maintenance schedules, and monitoring performance, you can maximise the lifespan of your system and continue to enjoy its benefits for years to come.
