Solar Energy in Australia

Many Australians are switching to solar power systems as they work towards a sustainable future and learn to survive off the grid.

The year 2021 was a milestone for solar energy in Australia. According to Clean Energy Regulator (CER) data, 3.04 million homes and businesses installed solar panels, adding 2.88 gigawatts to the grid. Moreover, CER data indicate an increase of 4.5% in solar power installations and an increase of 8.6% in solar power capacity.

Using solar energy to power your residence or business is an environmentally friendly option. There are no direct glasshouse gas emissions because solar energy generates electricity rather than fossil fuels.

Sunlight is a renewable energy source, so it will never run out. Coal and gas are fossil resources that will deplete over time. And in Australia, there is abundant sunlight throughout the entire year. Cleanly and silently, solar panels convert sunlight into electricity.

Solar Panel Size in Australia 

A solar panel's dimensions include its length, breadth, and height. Solar panels are available in various sizes, but the standard measurement for residential use is 99 cm by 167.6 cm. This dimension is called a "module" and can vary marginally between manufacturers.

Solar panel sizes are significant in determining the number of panels required for a system. in addition to the total carbon footprint of your solar installation. When contemplating a solar panel system for your residence or business, roof or floor space must be available in addition to any height restrictions or zoning regulations that could affect your uses.

The dimensions of solar panels vary based on their application; for instance, panels used in commercial installations are typically larger than those used in residential buildings, and the dimensions of rooftop solar panels differ from those of portable solar panels.

Solar Cell Size in Australia

Solar panels are composed of solar cells, the squares visible on the boards. Cells directly convert light energy into electricity by using the photovoltaic effect. The more solar cells a solar panel contains, the more power it can generate.

Historically, solar cell proportions have been 156mm x 156mm; however, they have increased over the past three to four years, resulting in solar panels with larger dimensions.

Monocrystalline silicon, polycrystalline silicon, and thin-film solar substrates can all be used to create solar cells. The outputs of polycrystalline and monocrystalline solar panels differ. Solar panels with monocrystalline silicon solar cells are typically the most efficient, meaning they do not need to be physically large to provide high outputs.

Rooftop Solar Panel Size in Australia

Although solar panels in Australia come in standard measurements, manufacturers still determine their solar panels' size and output capacity. Traditional solar panels measure 1.70 m x 1 m and generate between 250 and 340 volts. Typically, the variation in output does not affect the dimensions of a single solar panel.

Solar panels are traditionally divided into two sizes: 60-cell and 72-cell solar panels. Size in watts corresponds to tangible dimensions and output power. For example, 60-cell solar panels measure 99 x 167.6 cm and produce 270 to 300 watts, while 72-cell solar panels have an average output ranging between 350 and 400 watts due to the extra row cells.

Standard residential solar panels typically contain 60 solar cells (or 120 solar cells divided in half) and generate between 250W and 400W of electricity. These panels can differ from 1.6m tall by 1m wide to 1.7m tall by 1m wide.

Portable Solar Panel Size in Australia

The use of solar panels has expanded beyond rooftops and permanent installations. Numerous portable solar modules are now available for camping, RVs, and emergency supplies. Also, portable solar panels for residential use are available for purchase. It is convenient to have one at home.

Due to their portability, portable solar panels are always smaller than rooftop solar panels, as their name implies. Only compact, foldable solar panels are ideal for transport and portability, whether camping, RVing, hiking, or living off the grid.

Typically, portable solar panels measure 45 cm in height by 25 cm in width. Although portable solar panels are smaller than rooftop solar panels, their efficacy remains unchanged regardless of size.

Solar Panel Weight in Australia

The weight of solar panels is significant for several purposes. The robustness of the roof or structure on which a solar system is to be installed is of the utmost importance. The effort required to transport and install the panels on a top should also be considered.

When designing a solar energy system, it is essential to consider the weight of solar panels as it will compromise the roof's structural integrity. Suppose your roof cannot sustain the solar panels' weight. You may need to fortify it or locate alternative mounting options, such as portable solar panels. In addition, the importance of the solar panel weight will affect the shipping and installation costs.

Depending on the type of solar panel and the materials used in its construction, the weight of a solar panel can vary. Most standard solar panels weigh between 40 to 50 pounds, but heavier panels can weigh up to 60 pounds.

Because of their greater height and weight, 72-cell solar panels are more difficult to handle during installation due to the effects of wind.

Solar Panel Output in Australia

Solar panels can vary in their ability to capture the sun's beams and generate electricity depending on their brand and model. The wattage output of the rooftop solar panels can range between 250W and 400W for residential and commercial use.

And the output of portable solar panels can range from 60W to 200W. To determine how many solar panels are needed to produce a certain amount of electricity, use the following formula:

Solar System Size = No. of Solar Panels x Solar Panel Output

Watt is the unit used to quantify the transfer rate of energy. One kilowatt equals one thousand watts. The wattage rating of solar panels specifies the maximum power the solar panel can deliver at any given moment, revealing their capacity.

kWh or watt-hour is a unit of measurement for energy production or consumption over time. The team will be the actual electricity produced per kW per kilowatt-hour (kWh) on your electricity bill.
