SOLAR MAINTENANCE | SOLAR REPAIRS
Concerned that your solar system isn’t producing what it should?
Or worried that the installation will lead to a fire in the future due to substandard equipment?
Cleaning of your panels
Check and secure any cabling under your panels
Check and cover any cabling exposed to UV
Check system voltages, current, and output
Check state of roof penetration and seals
Check earthing continuity to system and inverter
Check system compliance for items such as defective DC isolators
Solar maintenance for PV and hybrid systems including panel cleaning and compliance checks.
Did you know that a panel can lose on average between 5 and 10% of its output from dust? This is generally taken into account when calculating a system’s output which is why your initial results can be more impressive. However after a year or so of residue build up from dirt, or the occasional bird droppings, panels can drop their output significantly.
Are you concerned about the seals or enclosure integrity?
It astounds us what qualifies as a ‘roof penetration’ out in the field. In the solar industry it can mean shoved under a tile or a bit of silicon on the roof. In building terms it means a dedicated penetration sealed by both industrial roof grade sealant and a deck tie.
We can check and if necessary replace your roof seals thereby ensuring that it cannot leak. We can even check the integrity of your aerial or rooftop condenser penetration on the same run.
IP enclosures can also become exposed to the elements – often through the door on the front of the enclosure or through screw holes in the back. Some can simply decay in the sun. These enclosures are the MAIN CAUSE OF FIRE from solar PV in Australia. We vigorously check their installation and install metal sun shields over the isolators thereby offering some protection from the elements.
Is your output lower than expected?
We see a lot of incredible designs – panels split over multiple faces via one tracking channel – panels at different angles and sideways on rooftops – inverter operating ranges outside of specification. If your system fails the average daily production calculation and has no shading issues then chances are it’s designed incorrectly.
Roof and solar maintenance?
Does your solar system need to be removed for roof maintenance? We have experience working with a number of roofing companies taking down, reinstalling and re-commissioning solar systems.
Has your cabling been damaged by vermin or other works? We can repair any solar system issues and recommission the system on the spot – if the sun is on of course! Have your solar system repaired by specialists and get some free advice on the spot. We have been called out to fix a number of defects for customers who found that their installation company no longer exists. This added experience has given us a very keen eye for what can go wrong with a solar installation and an industry leading check and fix process for maintaining and inspecting solar PV systems. We are used to looking for some of the leading indicators of PV failure such as seal deterioration leading to water ingress, loose cabling leading to failed or high resistance joints, incorrect UV stabilization, yellowing or peeling of panels and many production issues caused by factors such as incorrect design or shading.
