- What is a grid connect solar power system?
A Grid connect solar power system supplies solar electricity through an inverter directly to the household (no batteries) and from there into the electricity grid – if the system is providing more energy than the house requires. As the inverter is connected to the grid, the solar power system is known as a grid-connect solar power system.
- What is a Feed-In Tariff?
A Feed-In Tariff (FiT) is the rate which you get paid for any excess energy exported to the grid. In Qld the Feed-In Tariff is set to a generous 44c/kWh and is the highest FiT in Australia.
- How Much Does A Solar Power System Cost?
The price for a solar power system varies depending on state and your house. For these reasons we recommend speaking with one of qualified solar consultants today.
- What Affects the Output of a Solar System?
The strength of the solar energy (radiation) available depends on the time of year, the time of day, and the latitude of the generation point. The amount of energy generated can be further affected by the amount of dust and water vapour in the air, the amount of cloud cover and any shading of the solar panels. Other factors that affect the performance include the inverter efficiency and wiring losses. Our solar consultants will be able to explain all of this to you during your free home energy assesments.
- Does Roof Orientation Matter?
The location of your panels affects your solar power systems performance. North facing roofs are ideal. However, if your solar panel system has to face East or West it will still continue to supply high levels of solar energy, and a possible solution would be to include more panels for your system to compensate for any orientation losses.
- What Size System Do I Need?
That entirely depends on your energy usage and your geographical location. A 1.5 kW system is currently the “entry point” for grid connect and attracts the most rebate .It will cover between 16 and 25% of the energy consumption of a medium household. A 4 kW system will cover 100% of the energy consumption of a medium energy use household. Use our solar power system builder to calculate your energy needs.
Any size grid connect solar power system will reduce your yearly power consumption and your power bill. Naturally the bigger the system, the bigger the benefit.
To make the most of solar power, the key is to implement simple energy efficiency strategies. It is easy to conserve energy by using appropriate lighting and efficient appliances. Running high power appliances such as electric bar heaters, electric hot water systems and air conditioners etc. is really not economical.
Instead of considering a very large solar system it is advisable to invest in energy efficient heaters, solar hot water and design features such as strategically placed vents or insulation to avoid heat entering the house in the first place. In summary – all your energy can be supplied by solar power and your budget and daily energy usage will determine the size of your solar power system.
