Frequently Asked Questions
How does solar work?
Solar cells are packaged within your solar panels to form photovoltaic modules, which create electricity from the sun’s energy. The DC electricity created is fed back to your inverter, which then translates into AC electricity for home energy use and for your appliances. Excess electricity is exported to the grid and you are credited for this with a feed in tariff from your electricity provider.
What are the benefits of installing solar?
The government rebate means immediate savings as it is deducted as a discount on the total price of the system
Guaranteed savings in your quarterly power bill
Environmentally positive carbon footprint
Adds value to your property
Reduces the impact of escalating electricity price hikes
Great overall return on investment.
What Government Assistance is available to install solar?
The Government provides an incentive which is called STC’s (small technology certificates). An STC is the equivalent of one megawatt hour of electricity created by your solar system and STC subsidy varies based on size of system, location and price of STC at the time of installation. You are able to assign your STC’S to your solar retailer in exchange for an upfront discount on the price of the system.
What size system should I install?
Your solar retailer will provide detailed modelling on consumption patterns and production of ideal system options which best suit your needs. This will factor in roof capacity constraints. Larger systems generally benefit from economies of scale with a benefit from the larger government incentive, production which would cover your consumption, greater excess electricity surplus for the feed tariff benefit and generally a shorter payback period on your investment.
Will my roof type matter?
Systems can be tailored to match your roof type. If your roof is not north facing, or flat roofed or depending on your roof covering, an ideal roof solar design will take into account these factors and will use the appropriate materials for maximising your solar production.
What if I have shading on my roof?
Tree shading or some shading caused by television antennas, vent pipes, etc are a common occurrence on roofs. An effective solar design will take into account these factors to provide you with the best possible panel array.
What if it is not sunny?
Ideal conditions will be a sunny day where you are likely to get maximum output of your solar system. If it is cloudy, you will still produce electricity but it is likely to produce less. Studies suggest that your solar system will produce between 10%-25% of solar output during cloudy days.
Will solar work during a blackout?
Your solar system will not work as it is designed not to be operational during a blackout. This is a safety measure to protect the line workers when the grid is down.
Do I have to maintain solar panels?
Solar panels are low maintenance, but would recommend that you monitor your production as that would be an indicator if any maintenance is needed. Example: Tree and vegetation growth, residue of dirt and grime, leaf deposits, bird droppings, etc. can impact on the efficiency of your panels.
There are accredited companies that specialise in maintenance and part of a maintenance visit could also include a full system check for any potential damage to panels, moisture penetration, frame corrosion, cabling, connections, seals, etc.
How does my installation help the environment?
As your solar panel system produces electricity on your roof, it is 100 percent renewable, free of pollutants and emissions. It is also directly impacting your carbon footprint, as your retailer modelling will illustrate. Solar aids the fight against climate change.
Can I add a battery later?
It is well possible to have a battery added to your solar system at a later stage, depending on the system size. Solar batteries are a great way to make the most of your panels and give you energy independence.
What are the warranties?
Solar panels have a performance warranty of up to 25 years, whilst top inverter brands like SMA/Fronius have a 10 year warranty.
