Solar System FAQs

Solar photovoltaic systems have low maintenance and servicing requirements. This means they are often installed and ignored until noticeable issues arise. Early detection of these issues will reduce the severity of any faults and, ideally, allow warranty claims to be processed within the required timeframe.

There are two main options that are most common to improving a solar system: (1) increasing the size of the solar system or (2) installing batteries.

Option 1: If you find that your daytime electricity consumption is too high, increasing the size of the system will allow your system to meet your demand.

Option 2: If you find that your daytime electricity consumption is too low, and you are exporting the majority of your electricity, having batteries conserves your energy for night time use.

  • If your solar installer is inexperienced or careless, the electrical work they perform might be a cause of failure for your solar system. One such issue that we encounter often is poor connections between the modules or strings of the solar system; if a technician incorrectly installs a connection, this might cause a high resistance joint. This high resistance joint generates heat whenever electricity passes through it. If this situation is not attended to for an extended period, it might cause an electrical fire.
  • If your inverter is malfunctioning and showing an error, chances are it might be a low insulation resistance fault from your solar panels. This commonly occurs due to poor manufacturing quality of the solar panels, where due to the extended period in the sun, the panels’ insulation between the frame and solar cells degrade. This low insulation resistance of a single panel is then detected by your inverter and shuts the whole system down as a safety system, rendering your investment moot.
  • If your solar system is not designed and installed correctly and experiences localised shading of any of the panels on a daily basis, this situation might cause a failure in your solar system down the line. Localised shading is commonly caused by either vents or chimneys on your roof that shade part of a panel. Localised shading causes the shaded cells to experience a high resistance joint, which in turn generates heat and might potentially cause an electrical fire.
  • Buying a new house can be daunting, and with more houses coming with built-in solar as a selling point, new home owners can be unaware of the issues they bring.
  • It is best to ensure that when purchasing a new house, the solar system is functioning and operating correctly. Admittedly, this is easier said than done! Old inverters often do not have a display screen and it can be difficult to determine whether they are operational and performing as expected just based off the indicator lights. Newer inverters with a display screen are easier to investigate as the information such as daily production and past error faults are readily available.
  • The next step would be to manage the warranties of the solar system. Solar systems are meant to last upwards of 10 years, but the components are likely to encounter problems prior to that. All solar systems should have adequate documentation provided to the owner on purchase which details the warranties of the system.Ensure you have access to this information or a copy of the documents. This will make it easier for you to fix the system or claim warranties on it. Some manufacturers, such as LG, allow you to transfer the warranties to another individual, allowing the new home owner to make claims themselves. Alternatively, warranties could still be processed as long as there is a proof of purchase from the original owner.Overall, having as much proof or documentation of the system will give you the best opportunity to make a warranty claim, so making sure you ask for it on purchase of a new house.

Airconditioning FAQs

Air conditioning systems have a high energy consumption rate and many complex components involved. It is important to regularly service your system to keep it performing well and prevent system failure. Air conditioners that are not operating well require more energy to achieve the same temperature and therefore lead to higher electricity bills.

  • Ideally, you should have your air conditioning system serviced annually, preferably in the months before you use it the most. For example, you could have your system serviced during winter in preparation for a hot summer, or vice versa if you use it most for heating during the colder months.
  • The primary reason to get this annual service is so you are not caught out by high electricity bills caused by inefficiencies in your air conditioning system.
  • Another reason is to skip the high-traffic times when, because everyone is using their air conditioning at the same time, there is a high volume of air conditioning failures. You might be stuck for a long time waiting for a technician to service your system if you call during the hottest week of the year.
  • A split system is an air conditioning system with the condenser located outside the house with a head unit fixed to your wall.
    The advantages of split systems are their relative ease of installation, specific room cooling, and affordability compared to ducted systems. However, split systems limit your interior wall space because they require a head unit, as well as only cool the specified room.
  • A ducted system is an air conditioning system with the entire unit hidden either in the roof space or on the outside of the property.
    The advantages of ducted systems are that they provide uniform room cooling and have a concealed unit, and therefore they add value and marketability to your property. However, ducted systems have their limitations. They require adequate roof space in order to be installed, and they are more expensive than split systems.
