Frequently Asked Questions
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 and the quality of the solar modules. You can learn more about solar radiation levels for your area in our solar power system builder.
Prices vary according to size and location.
A feed-in tariff is whereby a grid connect system owner is paid for the electricity their system generates by a utility or government agency depending on your location you may receive between 9cents and 16cents per kWh.
That entirely depends on your energy usage and your geographical location. A 1.5 kW system is currently the “entry point” for grid connect. It will cover between 16 and 25% of the energy consumption of a medium household. A 4-5 kW system will cover 100% of the energy consumption of a medium energy use household.
Any size grid connect solar power system will reduce your yearly power consumption and your power bill. Naturally, the bigger the system, the bigger the benefit.
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. Running high power appliances such as electric bar heaters, electric hot water systems and air conditioners etc. is not economical.Instead of considering a very large solar system; you can also invest in energy efficient heaters, solar hot water and design features such as strategically placed vents or insulation to avoid heat entering the house in the first place. In summary – all your energy can be supplied by solar power and your budget and daily energy usage will determine the size of your solar power system.
Several aspects will need to be evaluated to determine if your home is a good solar site, such as orientation, space available, shadows on the space available and your current electricity usage. The best site will be one with adequate north-facing roofs that have no shade. Variations on that will cut into the productivity of the system.
- Solar Panels: Minimum 10-year product warranty and 25-year performance guarantee.
- Inverter: 5 – 10-year warranty.
- Mounting System: 10-year product warranty (manufacturer).
- Workmanship: 5-year warranty on workmanship (installer).
Between monocrystalline and polycrystalline there isn’t a lot of difference except that a polycrystalline panel is slightly larger than the equivalent wattage in monocrystalline. Thin film panels are larger again and the extra space can take up valuable rooftop real estate in terms of adding extra panels at a later date.
A base installation rate includes the grid connect system being installed on a pitched metal roof facing north with the appropriate surface area available. Additional costs will be incurred for a flat or tiled roof; any equipment upgrades and extended warranties.
Yes. Additional solar panels can be added at any time to increase generating capability, but you might have to upgrade to a larger inverter. Alternatively, you could purchase a larger inverter when installing the system initially and then plan to add some extra solar panels later.
As the Sunrise Power Solutions systems are designed to Australian Standards, the reliability of components and consistency of power supply will be more than adequate for the loads specified.
The heart of a photovoltaic solar power system is the solar array. Made up of multiple panels (individually measuring roughly 1 by 1.5 meters), this array absorbs the energy of a specific range of available sunlight and converts this energy into electrical energy. The array is mounted on a frame that allows the panels to be securely mounted with minimal interference with the waterproofing and structure of the roof, as well as providing the correct aspect and elevation for the array so as that the maximum amount of available sunlight in received and converted.
A cable is run down from the array to the inverter, a device designed to efficiently convert the widely fluctuating power from the solar array into a predictable and usable energy feed. A second cable connects the inverter to your house’s switchboard, which is in turn connected to the main power grid, creating a continuous and dynamic system for the contribution of solar energy to your house. The inverter also acts as a simple data logger; an information screen on the inverter will display total energy production, daily energy production, and instantaneous power. These figures will fluctuate depending on the time of year, the cloud cover, and temperature, and will allow you to keep a record of your system’s performance.
Solar power systems can also be optionally 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. Ask your sales representative for more information.
Yes, the clean energy council recommend that your solar system should be checked on a bi-annual basis. Sunrise Power Solutions provide cleaning and maintenance service.
To install a grid-connected solar power system at your premises, you will need to have a compatible switchboard and meter.
A smart meter will need to be installed if you don’t already have one. Sunrise Power Solutions will handle all the paperwork to ensure you get a smart meter installed after your solar installation. This process can take up to 30 business days, depending on the retailer and network provider.
Grid connect 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 and electricity, you draw your power from the grid and your electricity meter measures your consumption.
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.
Yes, there are many different options on the market now and Sunrise Power Solutions will guide you through the battery buying process.
The solar system is wired into your existing fuse box via a 15amp circuit breaker.
Usually a string inverter is placed alongside the fuse box. Micro inverters are installed underneath the solar panels.
