Grid connect systems supply solar electricity through an inverter directly to the household and to the electrical grid if the system is providing more energy than the home needs. When power is supplied to the mains grid, the home owner will usually receive a credit or a payment for that electricity. This is called a feed in tariff.
A feed-in-tariff is the amount an electricity retailer pays you for any electricity your solar PV system generates that you don’t use, and is instead fed back into the grid.
Alternatively, we can advise you on the benefits of installing power storage.
The price of solar systems has fallen dramatically over the last 10 years, making it an increasingly attractive option for homes and businesses. Pay back periods are now as low as 4.5 years# for solar and 8 years# if you include battery storage.
The upfront cost of your solar PV system is influenced by a number of different factors:
#payback periods will vary depending on each individual circumstance
The amount of money your household will save on power bills by going solar is dependent on a number factors, including:
Under the small-scale renewable energy scheme, eligible small-scale Solar systems are entitled to a number of small-scale technology certificates (STCs).
The number of small-scale technology certificates that can be created per system is based on its geographical location, installation date, and the system size.
Solar PV systems up to 100 kilowatts are eligible for STCs. The amount of STCs created by a solar power system reduces proportionally each year until 2030 in which the solar power system will not create any STCs. Systems greater than 100kW are not eligible to create STCs, they create Large Generation Certificates which are for every megawatt hour of electricity generated and created at the end of a period that the energy was generated.
Under the Small-scale Renewable Energy Scheme, eligible small-scale renewable energy systems are entitled to a number of small-scale technology certificates (STCs).
As a guide, one small-scale technology certificate is equal to one megawatt hour of eligible renewable electricity either generated or displaced by the system.
You can calculate the number of small-scale technology certificates a system may be eligible using the small generation unit calculator and solar water heater calculator.
To be eligible for STCs, your solar system must be installed by a Clean Energy Council accredited installer.
You should ask to see your installer’s accreditation.
All Bristile solar panels, inverters and balance of system comply with Australian standards. You can also visit the Clean Energy Council website where they maintain a list of all solar modules and inverters that meet Australian Standards for use in the design and installation of solar PV systems. Only systems that use products from the approved lists are entitled to rebates in the form of small-scale technology certificates (STCs).
Reclaim PV Recycling operates an Australian solar panel reclaiming scheme throughout Australia.
The Australian solar industry is well regulated and safe. Solar panels and inverters sold in Australia must comply with a range of standards that maximise safety and reliability. The Clean Energy Council maintains a list of currently approved solar panel modules and inverters.
Solar panels do not generate power at night. Once the sun goes down, your home or business will start to draw power from the main grid as usual or, should you install a battery storage system, from your batteries.
Solar panels still work on a cloudy day due to their excellent low light performance; however, they will not generate as much electricity as when the weather is clear and sunny.
You should contact Bristile immediately so we may arrange a system evaluation and action warranty repairs where applicable.
Our solar panels come with a minimum 10 year product warranty. Both solar tiles and solar panels have a 25-year output warranty on the Solar Cells. Our inverters and battery storage solutions also have a 10 year warranty.
Several aspects will need to be evaluated to determine if your home is a good solar site, such as orientation, available space, shadowing on the available space and your current electricity usage. The best site will be one with adequate north-facing roof planes that have no shade.
Yes. However, your system will work more efficiently and be more cost-effective if designed to match your requirements today.
Yes. All our systems are battery ready so you may add batteries in the future.
Yes, a 5kw system typically has a payback period of 4.5 years, depending on your load profile. We would be more than happy to conduct an energy audit so you can make an informed decision, as the pay back varies household to household.
The power from your solar system will be used to meet your energy needs first; any excess will feed into the grid. Check with your electricity retailer to see what feed in tariffs they are offering and be careful to shop around as not all electricity retailers offer the same. Whether this rises on the back of competition or continues to be reduced; only time will tell.
This is a system that can store solar generated energy that would ordinarily be exported to the grid when the household load is lower than the power generated by solar.
The strength of the solar energy (radiation) available depends on the time of year, the time of day, and the latitude of the generation point. The amount of energy generated can be further affected by the amount of dust and water vapour in the air, the amount of cloud cover and any shading of the solar panels as well as the quality of the solar modules.
YES, a system with solar panels facing in a southerly direction will generate less than one with a northerly aspect. However, east/west installations can be a good option depending on the household’s usage patterns.
That entirely depends on your energy usage and your geographical location, however any size grid connect solar power system will reduce your yearly consumption from the grid and your power bill.
To make the most of solar power, the key is to implement simple energy efficiency strategies. It is easy to conserve energy by using appropriate lighting and efficient appliances.
Solar modules have been tested in the field showing small reductions in power output over 25 years. Our solar panels carry an output warranty of 25 year and electronic components such as inverters and battery storage systems have a 10 year warranty, however typically each of these components will outlast their warranty.
Most insurers will allow you to include the system under your home and contents insurance, but please check with your insurance provider first.
Using a comparison to a car, the average vehicle in Australia travels 20 000 km per annum, which is equivalent to 3.3 tons of carbon dioxide discharge annually. A 5kw grid connected system will prevent 3.3 tons of carbon dioxide being generated through coal fired power generation per year – so it’s the equivalent of taking a car off the road.
Solar Panels, Inverter (string or Micro), roof mounting equipment, DC and AC cable, Isolators and a label kit and in some cases may also include a storage system.
Solar systems may also be fitted with easy-to-use remote monitors, internet enabled data loggers, and even sensors to determine solar availability, panel temperature, air temperature, and wind speed.
There is very little maintenance required. Electronic components should be maintenance free. Each system is provided with instructions for maintenance.
In order to install a grid connected solar power system at your premises, you will need to have a compatible switchboard and meter.
A meter exchange may be required after the installation of your new solar system. The energy produced by your solar system interacts with the main power grid and the loads in your house. Without an appropriate mains meter, any energy you sell to the power grid can be inaccurately measured, or even completely disregarded, greatly reducing the system’s effectiveness in reducing your energy bill. A ‘bi-directional’ meter is installed in place of the existing one-way meter, allowing the reading of energy in both directions; both buy and sell.
Grid connect solar systems direct excess electricity produced during the day back into the local electricity grid. You then receive a credit for any power that your system supplied to the grid. During the night when your system does not produce any electricity you draw your power from the grid and your electricity meter measures your consumption. Alternatively, you can install a power storage system and use this stored power during the night.
The grid connect inverter will automatically shut itself off within a few milliseconds of a blackout, to avoid the potential of a dangerous “brown-out” in your home and to prevent back feeding into the grid. Therefore, even though you have a solar system during a blackout you will not have power available. If you want to keep on having electricity available during a blackout then you would need to have back up batteries installed as well, which will add to the cost of the system.
Usually the inverter is placed alongside or near the switchboard. The inverter is quiet and has a display to show the electricity generated and other data options such as total electricity generated since installation are available.
The system weighs approximately 30 kilograms per square meter.
1.0 kW of solar needs approximately 4m2, so a 5kW system needs approximately 20m2
