Common Problems with Residential Solar Energy Systems – And How to Avoid Them
Switching to residential solar energy systems is a smart move for both the environment and your wallet. Solar panels offer a clean, renewable energy source that can significantly reduce your electricity bills. However, like any home technology, solar power systems are not entirely maintenance-free. Knowing the most common problems can help you protect your investment and ensure your system runs efficiently for years.

Shading and Dirt Reduce Solar Panel Efficiency
Even partial shading from trees, nearby buildings, or debris like leaves and snow can dramatically decrease solar panel efficiency. In fact, a single shaded cell in a panel can reduce the output of the entire array. Regular cleaning and proper panel placement during solar installation are key to maximising energy output.
Inverter Failures Are a Top Issue
The solar inverter is the heart of your solar energy system—it converts the DC electricity generated by your panels into usable AC power for your home. Inverters tend to have a shorter lifespan of around 15 years, than solar panels 30 year lifespan. Keeping an eye out for warning lights or error messages on your inverter can help catch issues early. Consider investing in a monitoring system to track your solar production in real-time.
Poor Installation Can Lead to Roof Damage
Choosing the right solar installation company is crucial. Improper mounting of solar panels can cause roof leaks, water damage, or structural issues. Always work with certified solar installers and ask about their experience with your roof type.
Hiring a Cheap Electrician/Solar Installer
Selecting an electrician or solar installer based on the cheapest price is not always the best financial decision. They may fit poor quality solar panels or a cheap inverter with a short lifespan. This means you’ll likely need to buy a whole new system again within a few years – which will probably double your initial costs.

Wiring and Electrical Problems
Loose, corroded, or damaged wiring can cause power losses or safety hazards. These issues are often due to poor installation or long-term wear and tear. Schedule annual inspections to ensure your solar power system is in top condition and all connections are secure.
Environmental Damage and Weather Risks
Extreme weather events like hail, strong winds, or heavy snow can crack panels or loosen mounting hardware. If you live in a storm-prone area, consider protective add-ons or high-durability panels. Snow build-up can also block sunlight and reduce output; using snow rakes or waiting for natural melt-off can help.
Monitoring System Connectivity Loss
Many modern systems rely on Wi-Fi to connect monitoring devices. When your home internet is down or the signal is weak, performance tracking may fail, causing unnoticed power losses. Ensure your monitoring equipment is in a good location with strong connectivity.
Pests Can Cause Hidden Damage
Birds and rodents sometimes nest under solar panels, chewing through wires and causing hidden damage. Installing critter guards or mesh barriers around your panels is a good preventive measure.
If you think it’s expensive hiring a good electrician, try hiring a bad one.
Conclusion to common solar problems
While home solar panels are generally low-maintenance and highly reliable, being aware of these common issues can save you money and frustration. Proper solar panel maintenance, smart installation practices, and regular system checks are the best ways to avoid costly repairs and keep your solar energy system running at peak performance.
Also, it is worth noting solar energy is a specialised electrical field. To work with solar you need specific endorsements from the Electrical Workers Registration Board. Unfortunately, during economic downturns, more and more general electricians are taking on solar jobs, to subsidise their incomes. If a general electrician says they can do solar, ask them how many installations they have completed in the past week.
At Star-Delta, solar is our speciality, and our number one priority. We regularly complete 3-4 solar installations per week. We don’t play around with solar, we are solar!
