This a question many householders ask, during a SOLAR POWER ASSESSMENT.
Firstly it is important to note, technically only your electricity usage measured in kilowatts, during the sunny hours of the day can be offset and reduced.
Secondly any other monies raised from exported electricity, will go towards balancing out any electricity used outside of the sunny hours of the day and connection charges.
Whether you can eliminate your electricity bill completely will depend on your electricity usage and exported electricity. This is dependent on having a large amount of solar generated power in relation to used power.
When connecting a large SOLAR POWER SYSTEM, for example 5kW or over, to a household with low electricity usage under the roof during the sunny hours of the day, there is great potential to eliminate electricity costs. There can be enough revenue from the exported electricity to balance out other electricity costs and service charges.
Other factors that need to be taken into account are that, the larger the solar power system, the greater the cost and the greater use of rooftop real estate. The payback period for the larger systems, may in some cases be longer, due to Government pricing rebates being maximised, to the smaller solar power systems.
So if you are looking to eliminate your electricity bill completely, you first of all need to understand your electricity usage and the amount of any feed in tariff offered by your electricity retailer. It is this feed in tariff that will generate you revenue for your exported electricity.
What is really important is that you understand the maths of the exercise.
