Australia has the highest solar absorption in the world, with around 30% of homes having rooftop solar PV. By 31 January 2022, more than 3 million rooftop solar PV systems have been installed across Australia. The cost of a home solar PV system starts at around $3500 for a basic installation. Prices continued to drop as demand and mass production increased. (Source: Department of Climate Change, Energy, the Environment and Water – energy.gov.au)
Technology and the market are rapidly evolving. Solar PV systems are important and are designed to be long-term investments that, once paid for, provide free electricity during the day for the owner, saving them money. A solar panel can be placed so that it faces the sun most of the day, but it will only generate electricity for how long a day is for that place and time of year. Solar energy users estimate daily solar power supply using “equivalent peak sun hours”. Visit this page to learn tips and choose the best solar panel.

The placement of solar panels is just as important as the type of solar panel used in a specific situation. The general rule of thumb for installing solar panels in the southern hemisphere is to face true north (and in the northern hemisphere, true south). Remember that the true south geographic, not magnetic when talking about true south. In other words, instead of using the directions of a compass, you should orient your solar energy system based on the lines of longitude on a map.

Solar panel mapping tools or programs can help you maximize your solar potential.
National map
The National Map is an online map-based tool with a fully open design that facilitates access to geographic data from the Australian government. Geoscience Australia (GA) has partnered with CSIRO’s Data61 to manage the National Map to organize the data and develop the software.
- provides quick access to authoritative and other spatial data to government, business and the public
- Facilitates open data in federal, state and local government bodies
- provides an open framework for geospatial data services that support commercial and community innovation

The Australian PV Institute (APVI) solar mapping tools
An interactive national map and chart showing real-time performance information for solar PV installations across Australia is available on the APVI website.
The live solar PV map or APVI solar PV maps and tools track the use and impact of solar PV across Australia to help inform research and investment decisions.
Map included
- information on how much PV is installed in Australia including estimated electricity generated each year and in which locations (identified by postcode)
- market data and trends
- historical and live performance data covering all of Australia’s main climate regions, contributing to Australia’s load by region electricity market.
This program increases awareness, confidence, and information on PV performance and capacity. It gives users access to information that can be used to conduct sound research on solar markets, performance, reliability, and integration of energy markets and networks.
The data can also be used to better understand elements that improve the efficiency, reliability, and quality of PV electricity.
The Australian PV Institute is a non-profit, member-based organization that conducts collaborative research and analyzes data. It provides reliable and authentic information to support the growth and adoption of solar photovoltaics and related technologies.
The Australian Renewable Energy Agency (ARENA) is funding this project.

The difference between spatial and geospatial data
Geospatial data is time-based information that describes objects, events or other features connected to a specific location on the earth’s surface.
The shape and location of components and boundaries, such as geographic features, structures, survey marks, land parcels, street addresses, and local government and administrative boundary areas, are described by spatial data.
Large sets of spatial data are often gathered from multiple sources in various forms to create geospatial data, which may include information from a variety of sources such as social media, satellite imagery, weather, mobile phone data, and census data. The most beneficial use of geospatial data is when it can be found, shared, analyzed, and integrated with traditional business data.

Types of solar PV systems
A solar PV or photovoltaic system means electricity as the movement of an electron. When sunlight shines on solar cells, it causes electrons to be released from their place, leaving a hole where another electron can fall and interact with it. This phenomenon is the Photovoltaic Effect or called solar PV. Photovoltaic called PV. Solar PV systems can be

How to design a solar PV system?
- The sun shines on solar panels that produce Direct Current (DC) electricity.
- The DC power is fed to a solar inverter that converts it to 240V 50Hz AC power.
- 240V AC electricity is used to power the appliances in your home.
- Excess electricity is fed back into the main grid.

The solar inverter converts the DC electricity produced by the solar panels into 240V AC electricity, which can be used in the property/home, exported to the grid, or stored in a solar storage system. battery.
The big advantage of a larger solar PV system is that it’s easy to add a solar battery, use the capabilities of your solar inverter to its full extent, and just generate more power during the day so you don’t have to rely on it. in grid electricity. You can start making the most of your solar PV system by installing a solar battery, like the Tesla Powerwall 2.

Installation of solar panels
The cost of installing a solar system can vary and is affected by a variety of factors, including your location, the retailer or solar installer you choose, the solar rebates and incentives offered, and the size and solar panel technology in your system. Visit this page to find out if you should install solar panels on your investment property.
Here are some important steps to consider:
- Get multiple solar quotes to find the best solar retailer for your needs
- Find out what federal and state rebates and incentives are available
- Determine the most effective solar power system and solar panel size for your needs and budget
- Check that your solar retailer can provide evidence that your new solar panels have been validated as genuine, meet Australian Standards, and have a warranty you can trust.
