When sunlight makes contact with a solar photovoltaic (PV) panel, direct current is produced, with the inverter transforming this current from Direct Current (DC) to 240v Alternating Current (AC). This can be generated for home use or transferred to the national grid.
Monocrystalline and polycrystalline panels serve the same function in the overall solar PV system and possess many common features. They both absorb energy from the sun and turn it into electricity, they are both made from silicon and they are both durable. However, there are slight differences. The main difference between the two is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single crystal of silicon, while polycrystalline solar panels have solar cells made from many silicon fragments melted together.
Yes, there is. The solar hot water system simply uses the sun to directly heat water. A solar PV system converts sunlight into electricity for home use or to be fed into the electricity grid. The heat output of the sun is not crucial for solar PV systems, but the amount of sunlight available definitely is.
Solar PV (photovoltaic) was first discovered in 1839 by French scientist Edmond Becquerel. Scientists made solar cells of selenium in the 1880s. Subsequently, modern PV technologies were developed at Bell Labs and RCA Labs in the mid-1950s.
No, you cannot, these solar panels are functional for electricity only. You need a thermal solar system to heat water.
Generally, grid-connect systems direct excess electricity produced during the day back into the local electricity grid, so there is no on-site storage as such. You then receive credit for any power that you put back into the grid. At night time, you automatically use electricity straight from the grid. Off-grid systems store energy produced during the day in deep cycle batteries for use as required. Learn more about solar batteries here and storage, here.
On sunny days, the panels obtain the best possible electricity collection but on cloudy days, the panels will not absorb the same amount. The panels would only accumulate about half the output that would be acquired on a sunny day. If the electricity on a cloudy day is not enough to cover your household requirements, the system will utilise power directly from the grid. The performance of your solar PV system is affected by cloud cover; when there is not enough light to produce electricity, you will use electricity from the grid.
To do this, you would need a battery backup.
Yes, this is definitely possible. Battery backup systems require additional components such as a solar regulator, batteries and an inverter.
Any size solar solar PV system will definitely reduce your power bills, however our consultants are trained to recommend the best fit for your individual circumstances.
Solar systems are lightweight, but with very strong aluminium mounting frames, they typically distribute a total weight of just 8kg to 12 kg per square meter.
When you buy a solar PV system, all of its benefits (including the warranties and electricity savings) are directly linked to the property, so that even if you relocate, all warranties still remain, meaning the new owner becomes a recipient of these benefits.
There are several aspects to consider when determining if your home is a good solar site, such as available space, orientation, shadows on the space available and your current electricity consumption. The perfect site is one with adequate unshaded roof space.
Please get in contact with our team, who will put together a personalised proposal for a system that is suited to your property’s needs.
Any panel’s output will be reduced or cut off if in a shaded area, however some types of solar panels work better than others in shade.
Although it is best to install a solar system on the North side of the roof, it is also possible to install on the East or West facing side of a roof, provided that there is enough space.
At times, another source, such as mains electricity or a generator is required if there is no
sufficient battery backup for your solar PV system. When there is no sunlight, no electricity is produced, so you will need to draw electricity from another source such as the grid.
No. However, solar systems that are grid connected do not have a storage component, meaning any electricity that is not used at home is transferred to the electricity grid.
Yes, you can if you have enough unshaded roof space, and your energy distributor in the area allows for further capacity to be added. Please contact us here to find out more.
Solar PV only produces electricity in the daytime. The systems are dormant at night, meaning you need another source such as electricity from the grid or a battery.
The amount of electricity that you would get depends on these three factors:
STCs are a federal government-awarded commodity that you can use for trade. You can get these certificates when you purchase a renewable energy system.
Feed-in tariffs are fixed electricity rates that are paid to renewable energy producers for every kilowatt-hour of electricity your solar PV system feeds into the grid.
There are three types of solar systems:
Roof installation. This is the most common form of solar installation. It is better to maximise your unused roof space rather than occupying space around the home with your panels. In a situation where roof installation is not achievable due to costs and other factors, the ground installation method can be employed.
All the panels that we stock are tested and proven to withstand hail impact consistent with the requirements under Australian standards.
It is also called an AC panel. It is a piece of electronic apparatus used in PV cells for changing the waveform of the electrical current. The micro-inverter has a ‘micro inverter’ on each panel which converts direct currents into household electricity.
It is a DC to DC to technology invented to maximise the energy intake from solar photovoltaic or wind turbines.
Yes, if these are your reasons for wanting to do so:If you recently could not access a premium feed-in tariff and want more solar capacity. If there is unused space on your roof and you still want to take advantage of it. And for some other technical reasons.
There are additional charges for smart meter installations and connections. This amount varies between states and energy retailers.
Electricity is either connected to a single phase (230 or 240 volts), which is largely used for domestic consumption, or a three-phase, which is 400 or 415 volts. Three-Phase electricity is best used for intensive consumption such as in commercial situations. A single phase connection is more suitable for small or medium home consumption.
Yes, the extreme temperatures can cause a solar panel’s output to decrease. This is due to the electrical circuit changing the speed at which the electrons travel.
The amount of energy generated by a panel is directed proportionally to the amount of energy it receives from sunlight. Solar energy specialists calculate amounts of energy generated by the solar PV system.
