It is important that regular maintenance is carried out on your solar PV system. Undertaking regular maintenance will ensure your solar PV system is operating safely, correctly and efficiently.
Over time dust and debris can build up on your solar panels, which may compromise the performance of your solar PV system. In addition, water and moisture seepage, vermin, hail, wind and sunlight can all cause damage or deterioration.
By regularly undertaking maintenance, you will ensure your solar PV system is safe for the owners, staff and electrical workers working on the distribution network. Routine maintenance will also ensure system performance is maintained, allowing you to maximise savings on your power bills for many years.
Just like running a car, regular servicing is the best way to ensure your solar PV system keeps operating safely, correctly, and efficiently.
Frequently Asked Questions
How often do I need to maintain my solar PV system?
We normally recommend bi-annual maintenance of your solar PV system however this can differ between systems, products and environmental changes. Please take note of and follow the maintenance schedule provided by your solar retailer or installer.
Who can undertake routine maintenance on my solar PV system?
Unlike typical electrical products, turning a solar PV system ‘off’ at the switch does not mean that the components no longer pose an electrical hazard. For roof-mounted systems, some maintenance tasks may need to be conducted on the roof which could pose additional hazards.
Why clean solar panels?
Anything preventing sunlight from entering the solar cells will reduce the capacity of those cells to perform at their maximum efficiency.
Environmental factors such as dirt, dust, grime, bird/bat droppings, lichen and especially salt all decrease the capacity of solar panels to work at their peak, leading to a decrease in output. Thereby having a detrimental effect on the primary reason for installing panel systems, i.e., to reduce power bills. ^
Won’t the rain clean my solar panels?
Rain often has minerals and other dirt in it that will do the opposite of cleaning your panels! Take the example of a car left out in the weather for 6 months. You can imagine the state of the windscreen; you would need to give it quite a clean before you could drive that car safely.
Well, that’s how solar panels look after being out in the elements for 6 months. That is why we recommend cleaning twice a year, especially in coastal and high traffic areas that experience frequent dust and sand abrasion.
^If cleaning is deemed necessary, we will advise you and can provide your details to an authorised solar panel cleaning company for a quote.
*Extension of solar PV system life is not guaranteed and maintenance will decrease the chances of safety incidents.
What is involved?
Maintaining your solar PV system involves much more than simply cleaning your solar panels. Regular maintenance of your solar PV system should ensure:
- solar panels are clean, secure and free of defects
- no parts have deteriorated/corroded
- vents are free of debris
- switches do not have any defects
- wiring has not been damaged/has not deteriorated
- electrical checks to ensure all components are operating as intended
- confirming fittings and cables are securely attached
- reviewing the inverter display panel for recorded faults
- checking that access to the isolator switches has not been impeded, and/or
- making sure the emergency procedures for shutdown and isolation are clearly displayed.
