Frequently asked questions

How often should I have my panels cleaned?


Depending on your location, usually annually is sufficient however in some areas it is neccessary to have the panels cleaned twice a year.




Can I clean my own panels?


Never attempt to clean your own panels. Apart from the associated risks when climbing on a roof, a professional will be aware of electrical faults and avoid possible electric shocks.




But the rain cleans my panels. Doesn't it?


You only need to look at your car after its been out in the elements for a period of time. What was once a squeaky clean white car is now a murky shade of brown. Rain actually contributes to the problem especially if your panels are effected by lichen or the tilt of the panels is minimal.




What is a HOT-SPOT and how does it effect my panels?


Hot-spot heating occurs when there is one low current solar cell in a string of a least several high short-circuit current solar cells. Essentially the entire generating capacity of all the good cells is dissipated in the poor cell. This results in local overheating, or hot-spots, which leads to destructive effects, such as cell or glass cracking, melting of solder or degradation of the solar cell.




I was told my panels are self-cleaning?


What rubbish! A cheap sales tatic used by unethical solar companies to avoid after sales services. Solar companies are primarily selling solar systems with large profits and are more interested in the thousands of dollars they can make from a new sale, not the pocket change from actually providing there customers with a full service offering.




Whats a Annual Anti-Islanding test?


The Anti-Islanding test is a procedure that must be carried out by a solar professional. The test determines the time intervals in which the solar inverter shuts down ie disconnects from the grid and the time in which it reconnects. Shut down must be 2 seconds or less and reconnection must be 60 seconds or greater. The test is a safety procedure that ensures your solar is not feeding electricity back into the grid in the situation that the grid is shut down for repairs or maintenance.

Do you use soap and detergents to clean solar panels?


NO. Many solar panel manufatures will void your warranty if the panels have been cleaned with soaps and detergents. (plus your tank water wont taste so good) Sims uses pure water, leaving your panels spotless and streak free.
