Grid power is the network of poles and wires connecting electricity supply to your home or business. A solar PV system is your own solar generated source of electricity.
A Feed in Tariff is the amount per kW/h your electricity retailer will offer you for any excess solar generated power you feed back to the grid. Every state has different tariffs the feed in rate is reviewed in Victoria annually.
A solar PV (Photovoltaic) system is basically made up of mounting rail and associated hardware, solar panels, inverter or microinverters, and electrical wiring.
A micro-inverter, is a small device installed on the mounting rail behind each solar panel. It converts direct current (DC) electricity generated by the solar panel to alternating current (AC) electricity. A microinverter is silent and there is no moving parts. With an internet connection, the system owner can then monitor their own solar energy production. To see the many benefits of microinverters, click here.
Solar panels convert sunlight to DC electrical power. The panels are connected to an inverter or microinverters, which then converts DC voltage to AC mains power which is synchronised, used immediately in the home via the main switchboard, with any excess fed back into the grid via the electricity meter. When electricity usage is high, you will be using your own solar generated power and power from the grid.
Solar power production is dependent on the irradiance level of sunlight available, therefore cloudy days will affect the performance of your solar system. A solar system does not produce electricity at night.
In the southern hemisphere, north facing solar panels are the preferred option due to more power produced over a longer period during the day. The tilt or roof angle will also affect power production also.
The use of microinverters is a huge bonus where there is little or no north facing roof option. As each panel works individually, you are getting the maximum output available wherever each panel is facing.
It is a distributor requirement to obtain a pre-approval for every solar system prior to installation. Once approved and your system deposit is paid, installation can be completed usually within a couple of weeks depending on the weather. If you are applying for a Victoria solar rebate this should be secured first.
Most insurers will allow you to include your solar system in your home and contents insurance, but you should check with your own insurance company first.
