Frequently Asked Questions

Frequently Asked Questions

  1. What is a grid-connect system?

    A grid-connect system is a photovoltaic power system that is energised by photovoltaic (solar) panels and connected to the electricity grid. When the sun shines on photovoltaic panels they generate Alternating Current (AC) which is converted into Direct Current (DC) by a solar inverter. The electricity generated by the system is first used to power any appliances that are being used in the home or business and any excess power is then fed to the mains electricity grid. The owner of the system is then paid a feed-in tariff by their energy retailer for any electricity exported to the main grid.

  2. How do I know which system size will be suitable?

    When deciding which sized solar suitable will be suitable for you a number of factors need to be considered. These include your motivations for having a solar system installed. Are you looking to eliminate your power bills or just reduce them? At 30 North we tailor each of our solar systems to the needs of our clients taking into consideration their budget, their current and future energy needs and their site. During a consultation 30 North can provide you with a detailed design of a tailor-made solar system that is suitable for your needs.

  3. How long will it take to receive ‘Permission to Connect’ to the electricity grid?

    For residents seeking permission to connect to the Energex grid applications can now be processed online and permission can be granted usually within 24 hours. 30 North will process your Permission to Connect application with Energex after signing a contract.

  • Do solar systems require maintenance?

    Yes. 30 North recommends annual maintenance of your solar system. View our Testing page for more information:

    System Testing
  • Will a solar system work for me?

    We surely hope so! Two of the biggest factors that should be considered when deciding if solar will work for you are the amount of sunlight our roof receives and the amount of open and suitable roof space you have. 30 North can conduct an assessment of your property to let you know if it is suitable for a solar installation.

  • How long will it take to pay off my system?

    The time it will take to pay off a solar system relies on a number of factors and varies for each consumer. Contributing factors include the size of the system, the quality of the panels and inverter, the orientation of the panels, any shading that may occur, the feed-in tariff you are paid, the amount of electricity you consume and the amount you export to the grid. 30 North will assess all of these factors and provide you with average performance outputs and an estimated payback period during a consultation.

  • How much will I save?

    Savings will depend on how much you pay for electricity, your feed-in tariff and your energy consumption. 30 North will provide you with an estimate of your potential savings during a consultation.

  • What is a feed-in tariff?

    There are two types of feed-in tariffs: gross and net. A gross feed-in tariff pays a premium on all electricity that is produced by a solar system and a net feed-in tariff pays a premium for any excess power that is exported to the main electricity grid. The amount paid and the type of feed-in tariffs available varies from state to state. In Queensland owners of residential solar systems are generally on a net feed-in network agreement.

  • How much will I be paid for my feed-in tariff?

    Feed-in tariffs are regulated by state governments and therefore vary from state to state. In Queensland the feed-in tariff is up to your energy provider to decide, in most cases the FIT is $0.06c

  • <

    (a) Your application must have been submitted before the deadline:

    With the recent changes made by the Queensland Government to the 44 cent feed-in tariff, there are some rules to ensure eligibility. Eligible persons must have applied for the tariff before the 9 July 2012 cut off date and they would have received a Network Agreement from their energy distributor notifying them of the successful application.

  • Does 30 North measure my roof via Google Earth or will they come to my property and properly measure the roof?

    30 North do not measure roofs using Google Earth or Near Maps. We will come out to your property and get up on your roof and accurately measure it. This means that we can accurately determine what sized system you can fit on your roof and provide you with a fully inclusive quotation with no hidden extras. This also ensures things can run smoothly on the day of installation with no redesigns required to allow for the installation to go ahead.

  • What will happen to my solar system when the sun goes down?

    As electricity is generated by your solar system from sunlight, when the sun goes down your system will not produce electricity. At the end of each day when the sun goes down your solar inverter will automatically shut down. Then when the sun comes up the next morning your solar inverter will automatically start up.

    In the evenings when your system is not producing power, the power required to run your home or business will be drawn from the main electricity grid.

  • What will happen to my solar system during a blackout?

    During blackouts it is a safety requirement that solar systems automatically shut down. This ensures that the system does not feed any electricity into the main grid while work may be performed to restore power. All solar inverters are programmed to automatically shut down within a few milliseconds of a blackout occurring. This will mean that during a blackout you will not receive any power into your home from your solar system or the main grid.

    Your solar inverter should start back up automatically once power has been restored to the main grid. You should however always check that your inverter has restarted after a blackout and if it has not you can manually start it back up by following the procedure in the user manual.

  • Will the system require batteries?

    Grid-connect solar systems do not require batteries as they are connected to the main electricity grid.

  • Can a solar system be installed on a double storey tiled roof?

    Yes. 30 North are experienced installers who specialise in complex installations. We have extensive experience installing on multi-storey buildings with varying roof types including tiles.

  • Does shade have an impact on the performance of a solar system?

    Yes shade does have a significant impact on the performance of a solar system. If a panel is shaded and it is wired in a series (wired in a string) with other panels, the output of all the panels in that string will be impacted by the shaded panel or panels. The best possible scenario is to install solar panels where there are no shading issues. This isn’t always possible due to immovable objects and unavailability of unshaded roof areas.

    If you do have shading issues on your roof the effects that shading will have on the performance of a solar system should be fully explained to you before proceeding with the purchase and installation of a system. 30 North conduct detailed site inspections and shade analysis and will discuss any potential shading issues to ensure you make an informed decision about going solar.

  • Do I need to upgrade my electrical system to accommodate a solar installation?

    To allow for a solar system to be connected to the main electricity grid the property’s switchboard must be in compliance with your electricity distributor’s requirements. Some switchboards may require modifications or upgrades to accommodate a solar installation. During a consultation 30 North will assess your current electrical system and should any modifications or upgrades be required we will inform you. If any modifications or upgrades are required to your electrical system they must be carried out by a qualified electrician paid for and arranged by the customer prior to the commencement of a solar installation.

  • What warranties are provided with the solar system?

    All of the solar panels that we supply and install come with a minimum 20 year manufacturer’s warranty, with many offering 25 years. This warranty guarantees the performance of the panels. All of the inverters that we supply and install come with a 5 year product warranty and the option to purchase a 5 year extended warranty at time of sale. 30 North offers a 10 year workmanship warranty.

  • Will my solar system have the same performance throughout the year?

    The strength of the solar energy radiation available does depend on the time of year, the time of day, the current weather conditions and the latitude of the generation point. The amount of power that is generated by your solar system can be affected by the amount of dust and water vapour in the air, the amount of cloud cover and any shading of the solar panels. During the winter months when the number of hours of sunlight decreases there will be a lower performance level of your solar system. In saying that, solar systems can also decrease in performance during warmer months when the temperature on the roof increases to the more extreme levels.

    A 30 North consultant can talk you through the performance levels you should expect from your solar system throughout the year. We use state of the art equipment which will give you a clear indication of the performance that you should expect.

  • How long will it take to have my system installed?

    30 North can generally complete most domestic installations within 4-6 hours. More complex, large or commercial installations may be completed over 2 days. During a consultation 30 North will determine how complex the installations is and tell you how long it will likely take to complete your installation.

  • Where will the inverter be installed?

    Inverters should generally be installed within close proximity to the fuse box. Inverters can be positioned in a covered area (garage or carport) or outside if there is no other option. It is preferred that an inverter be installed undercover however they can also be installed without cover as they are UV rated. During your consultation with 30 North the placement of your inverter will be discussed.
