FREQUENTLY ASKED QUESTIONS
A: Yes there are. They are in the form of STC’S (Small scale Technology Certificates) for systems 99.99kw or less & LGC’s (Large scale Technology Certificates) for systems 100kw or more. The amount of rebate you will be eligible for depends on your zone rating, how long you wish to sell them for and the current STC market price. At the moment in South Australia the number of STC’s per KW=20 and the STC price is approximately $38.
Therefore the amount of rebate per KW in SA=$760 so for 5kw=$3800, 10KW=$7800 to give you an idea.
This amount can be claimed as a point of sale discount when you sign up for a solar system and we will handle all of the paperwork for you.
A: If you size it correctly and use the power in your home when the solar system generates power then the answer is a resounding YES! This is because the cost of electricity increases the more you use. If you can turn appliances on when the sun is out you will use the energy from your solar system rather than the grid. This means you could be saving up to 40c per KW/hr instead getting paid approx 7c per KW/hr for feeding back into the grid.
Some of the energy hungry appliances that can be easily used throughout the day are:
- Washing machines
- Clothes dryers
- Pool pumps
There are many ways to save on your electricity bill some simple ways are;
- Change out old light globes for more efficient LED lights
- Switch appliances off at the power point to eliminate the standby power consumed, this could also be achieved by using a smart power board.
- A solar system is a great way to save on your electricity bill by using your own power you generate instead of buying from the grid
- Older appliances are not as efficient as some newer ones
A: L.E.D. stands for “light emitting diode” its advantages are
- High-levels of brightness and intensity
- Low-voltage and current requirements
- Reduced fire risk as there is low radiated heat
- High reliability (resistant to shock and vibration)
- No UV Rays
- No mercury as commonly found in energy saving CFL’s (compact fluorescent lights)
- Long source life (Usually 7-8 times longer than traditional lights eg:Flouros, Hi-bays)
- Can be easily controlled and programmed
A: An RCD is for personal protection against an electric shock, the RCD monitors stray currents and trips if an imbalance occurs such as current flowing through a person’s body.
A Circuit Breaker only protects the cable and does not provide any personal protection if a person comes in contact with live wiring.
An earth provide 3 types of protection “overvoltage protection” “voltage stabilisation” “safety”
- Overvoltage Protection: First, the grounding wire acts as overvoltage protection. In the case of lightning, a line surge, or unintentional contact with a higher voltage line—where dangerously high voltages end up in the system—ground wires provide an alternative path around the electric system, minimizing damage and sending that extra charge safely into the earth.
- Voltage Stabilization: A second purpose of the grounding wire has to do with voltage stabilization. In any system, there are many sources of electricity, with every transformer considered a separate source. The earth is the most omnipresent conductive surface and thus provides a common reference point for the many voltage sources in an electrical system. Without this, it would be extremely difficult to calculate the relationships of the various voltage sources to one another and a hazard could easily occur.
- Safety: Finally, a grounding system provides a certain level of safety for humans and protects property, as it removes any dangerous voltages in the case of equipment failure or system disruption and sends them safely into the earth.
If your system is “grid connected only” it will not produce any electricity if you were to experience a blackout, but if your system was “grid connected with battery storage” you would then use the stored energy in the battery’s to run certain dedicated circuits in your home.
If you have flickering lights, regularly blowing fuses, circuit breakers tripping.
Was your board manufactured before safety switches were mandatory? Are you getting a solar system installed? Or changing over your meter to a new one? There might not be enough room to install new safety switches or metering, these are all signs that you may need to upgrade your switchboard.
You should always have your switchboard checked over by a licenced electrician.
The power that you generate through your solar system with be used in your home first and then any excess energy will be exported to the grid and paid back to you at the current feed in rate of approx.
