Do solar systems require much maintenance?


Solar systems have changed the way we use energy for our homes, one of the biggest factors in stopping families from making the switch is the worry that solar systems require a lot of up-keep and maintenance. This is a myth, and we’re going to explain why!

Our solar systems are designed to completely pay for themselves in as little as 2.9 years with little investment needed each year to keep them running at full performance.

The maintenance myth

There’s a common myth that solar systems require extensive and costly maintenance, which often causes hesitation among families considering solar energy. However, this couldn’t be further from the truth. Solar systems are remarkably low-maintenance, primarily because they have no moving parts, reducing wear and tear significantly. Most of the maintenance involves occasional cleaning of the solar panels to remove dust and dirt, ensuring maximum efficiency. This task can often be managed with just a hose, and in many areas, natural rainfall does most of the work. They can withstand harsh weather conditions, from scorching heat to freezing cold. In terms of electrical maintenance, it’s generally minimal and might only require a professional check-up every 2-5 years.

Warranties keeping you safe

Solar power systems stand out for their reliability and long-term warranties, offering unparalleled peace of mind to homeowners. A pivotal aspect of this assurance lies in the robust solar warranties, typically spanning 25 to 30 years for solar panels and 10 years for inverters and batteries. These warranties ensure that your solar system will perform at a certain level of efficiency for decades, safeguarding your investment against manufacturing defects or environmental wear and tear. Furthermore, the key components of a solar system, such as inverters and batteries, come with their own warranties, usually around 10 years. These warranties cover any issues with performance or defects, ensuring that not only are the panels themselves secure, but also the essential components that keep the system running smoothly.

For homeowners and businesses venturing into solar energy, these warranties represent a significant safety net, promising long-term stability and reliability. They underscore the manufacturers’ confidence in their products and commitment to renewable energy, making solar systems a wise, worry-free choice for sustainable power generation. This assurance of quality and longevity, backed by extensive warranties, is a compelling reason for considering solar power as a viable and secure energy solution for the future.

What to expect when you own a solar system

  • Reduction in Electricity Bills: A significant decrease in monthly electricity costs due to the solar system generating a portion, if not all, of your electricity needs.

  • Initial Investment: Upfront cost for purchasing and installing the solar system, which is offset over time through energy savings.

  • Minimal Maintenance: Solar systems require low maintenance, generally involving occasional cleaning of panels and routine inspections.

  • Performance Monitoring: Access to monitoring tools to track the energy production and efficiency of your solar panels.

  • Weather Dependency: Energy generation is dependent on weather conditions, with more energy produced on sunny days compared to cloudy or rainy days.

  • Energy Storage Options: If equipped with batteries, the ability to store excess energy for use during non-sunny periods.

  • Long-Term Warranties: Solar panels usually come with long-term warranties (25-30 years), ensuring sustained performance.

  • Increased Home Value: Potential increase in property value as homes with solar systems are often more attractive to buyers.

  • Grid Connection: Depending on your system, you may remain connected to the grid, allowing for energy exchange or sale.

  • Government Incentives: Potential access to government incentives, rebates, or tax credits for using renewable energy.

  • Reduced Carbon Footprint: Contribution to environmental preservation by reducing reliance on fossil fuels and lowering carbon emissions.

  • Learning Curve: A period of learning to understand and manage the system effectively, especially for monitoring software and battery management.

What do I need to do when owning a solar system? A Lifetime schedule


  • Performance Monitoring: Regularly check the energy output through the system’s monitoring tool to ensure it’s performing as expected. Look for any significant drops in production.


  • Visual Inspection: Conduct a basic visual inspection of the solar panels for any visible damage, dirt, or obstructions.


  • In-Depth Inspection: Perform a more thorough inspection of the entire system, including the mounting structure, wiring, and inverters. Look for any signs of wear and tear.
  • Professional Check-Up: It’s advisable to schedule at least one professional inspection per year. If you choose to do it semi-annually, this is a good time for the first check-up.


  • Detailed Cleaning: Clean the solar panels thoroughly. In areas with less rain or more dust, this may need to be done more frequently. We have written a guide on how to best clean your solar panels, read here
  • Tree Trimming: If applicable, trim any trees that may have grown to shade the panels.
  • Review Energy Bills: Compare your current year’s electricity bills with previous years to track the system’s performance and savings.

Every 3-5 Years:

  • Battery Maintenance: If your system includes batteries, they may require more frequent professional check-ups and potential replacement after several years, depending on the type and usage.

As Needed:

  • After Severe Weather: Check the system after extreme weather events like bushfires, earthquakes etc
  • Warranty Check: Regularly review warranty information for all components to stay informed about coverage and necessary maintenance to keep warranties valid.
