Australia has taken a long way in the solar system to save green energy. And not only in Australia but across the country, we can see that 10% of suitable rooftops are now embedded with solar panels. Different sizes of solar systems are installed depending on the incentives, what prices are offered at the installation, and the electricity needs of any project(commercial/residential). It is the largest size deployed for residential applications.
Solar Panels and Roof Space Required for ten kw system:
Gradually, over time, the efficiency of solar panels has increased and improved, and due to that, the number of panels required to be installed for an 8kw system is 22-26 panels.
One needs to consider the space required between panel size and maintenance and access with exclusion zones of the property, like edges and ridges of the roof.
Cost of 10 kw system:
We all know about a federal rebate called STC offered by the Australian govt, and it covers 30-35% of the upfront cost of installing solar Based on the index provided by govt.,
How much energy will be produced:
Actual power output depends on various factors like:
- Location and Climate
- Tilt & orientation of the solar panels
- Presence or absence of shading
- How hot the solar panels get (overheating can reduce power output, while cooler conditions are generally more favourable)
- The quality and size of the system’s inverter
- The performance of the overall system
In all these points mentioned above, the common thing is the sunlight available in a given region. The solar industry uses a metric to measure Peak Sun Hours(PSH: equal to 1 hour of full daylight). As the sun moves through the sky, the strength of the rays it casts on the location(varies).
Payback & Returns on 10kw system:
Payback period & ROI depend on various factors, but the main thing to install in Australia is the low cost of installation and solar system compared to the high price of electricity bill. From state to state and distributor to distributor, FIT varies.
If you own a solar system, you think about consuming as much power as it produces, as it will save a great amount of power. The electricity purchased from retailers is higher than FIT offered by the same/ different retailer for excessive solar power.
