When considering installing Solar Panel in Australia on the roof of your home, there are a few things you need to consider to know what type of solar panel to install.
To best meet your needs, do not hesitate to ask yourself a few questions to best define your solar project:
Photovoltaic solar panels or thermal solar panels?
Can your roof accommodate solar panels?
How many solar panels will need to meet your energy expectations?
For what use of solar energy?
Total self-consumption? Self-consumption with the sale of surplus? Total sale?
To answer some of these elements, you need to look at your energy consumption.

110 kWh/m²/year for heating;
1,100 kWh/household/year for electrical appliances;
800 kWh/person/year for domestic hot water;
200 kWh/person/year for cooking.
It is considered that the power of the installation must cover approximately a third of its needs.
To note that:
if you have low needs and are looking for cheaper Solar Panel Sydney, you can opt for a self-consumption solar kit to assemble yourself;
How to size a solar project?
It is your consumption profile that will guide you in choosing the number of Solar energy in Australia to install.
Indeed, in a situation where you have a house of approximately 100 m², if the energy you use is entirely electric and if you use standard electrical equipment (washing machine, dishwasher, dryer, oven, television, etc.) you will need to install 3 kWp of solar panels, which represents approximately 20 m² of roof and 10 solar panels in total – the number of modules however depends on the nominal power of the photovoltaic panel you have chosen.
Rated power of a solar panel
the nominal power of a solar panel (expressed in Wc), indicates the maximum electrical power that a panel can provide under ideal conditions (a cell temperature of 25°C, an inclination of 30°C among others).
The Best Solar Panel Company in Australia has a cell efficiency greater than 20%. You should keep in mind that these data may change if you have skylights or chimneys for example, which can reduce the surface area available on the roof to accommodate your installation.
Yield of a photovoltaic cell
the efficiency of a photovoltaic cell (expressed in %), indicates the ratio between the photovoltaic energy generated and the quantity of energy captured by the system.
Use of solar energy
Self-consumption rate
the self-consumption rate represents the share of solar electricity consumed by your home compared to the solar electricity produced by your modules. By getting closer to a 100% self-consumption rate, you will maximize savings.

Working with professionals will allow you to produce a solar quote that meets your expectations as closely as possible according to:
the location of your house (sunlight, inclination, and orientation, etc.);
the characteristics of your roof;
and your consumption profile.

What is the Solar Panel Price in Australia for a 100 m² house?
Considering that a photovoltaic installation of 3 kWp is sufficient to cover the needs of a household living in a building of 100 m², the price of the photovoltaic installation will be around €8,500 (including the solar panels, the inverter, and labor). Therefore, for a house of 200 m², a larger installation would be necessary to meet the energy demand.
The sale of the surplus of your solar manufacturer in Australia within the framework of a purchase contract concluded with the organization Tindo Solar at a fixed price of €0.1339/ kWh over 20 years.
Please note that installations of solar panels on the ground, installed in a garden for example, do not allow you to benefit from the self-consumption bonus.
Profitability of installing solar panels on a 100 m² house in Sydney
Depending on the location of your house, you will be able to make your installation profitable between 11 and 16 years. Indeed, if you live in a sunny region, production and efficiency will be greater, reducing your energy bill and increasing the profitability of the installation.
How many solar panels to heat a 100 m² house?
Thermal solar panels, solar water heaters, or combined solar systems, allow you to supply your home with domestic hot water (DHW) and/or heating.
As with photovoltaic solar panels, you’re DHW and/or heating needs will determine the quantity of thermal solar panels to install in your home.
The surface area is available on your roof.
Depending on the nature of your project, your budget, and your energy needs. You can also invest in solar thermal via a solar water heater, a combined solar system, or even combine thermal photovoltaics using hybrid, hydraulic, or aero-voltaic solar panels.
How many solar panels do you need for a 100 m² house?
In the case of a 100 m² house running entirely on electricity. We can estimate that a 3 kW system is sufficient. This represents approximately 10 panels.
However, depending on the equipment used and the region where you live, the installed peak power may vary upwards or downwards. It is the installer who is responsible for evaluating the energy potential of your building through a feasibility study.
You can also make an indicative solar quote, which will give you an estimate of the power to be installed.
How much does it cost to install solar panels for a 100 m² house?
In addition, the average price per kilowatt-peak of photovoltaic panels is €2,500.
Between €8,500 and €10,500 for 3 kWp ;
Between €12,000 and €17,000 for 6 kWp.
To make your installation even more profitable. It is possible to sell the excess electricity that you do not consume to an energy supplier. The EDF OA system, for example, offers a feed-in tariff set at €0.1339/kWh.
What can be powered with a 3,000 Wp photovoltaic installation?
A photovoltaic installation with a power of 3,000 Wp (or 3 kWp) can provide up to 40% of the electricity consumption of a 100 m² house (4 people, excluding electric heating).
