Q: How can I see products working as they would on my home, factory or office?

A:The products we recommend are all online at www.reti.com.au

Q: What size system will I need?

A: We simply divide your average daily use buy 4.2 as a guide.


Q: Why are there so many different solar prices and Solar Panels to choose from?

A: It’s like all things, the most important is that the products have been tested and ranked, that they have a Manufacturer’s warranty that you can turn to. We only supply the products that come straight from the manufacturer and have his branding and warranty associated with that actual product. Check the quality of the performance against your solar prices.


Q: What happens if I have a warranty issue?

A: You contact the product manufacturer. The Importer or manufacturer is responsible for the solar panels and solar inverters. Our solar power price only covers the installation warranty, but we will contact the supplier or importer on your behalf and resolve the issues where possible.


Q: What is a Small Scale Certificate (STC) and how does it apply to me?

A: The STC is a form of stock used in green trading; it is seen as the form in which solar power rebates are provided, basically each size system receives a number of STCs which is multiplied by the value of the STCs on the day you sign your contract. Example: If your asked for a 4kW system you would have at your disposal 68 STCs at todays value for example $25.00 = $1,700 This would be subtracted from the initial cost of the solar system to give you the final cost of your solar system so if the cost of your system was $10,370 you would take away the rebate and have an out of pocket cost for the system of $8,670.


Q: Why use different inverters models for different size systems?

A: The number of panels and there output need to be matched to the best possible inverter specification to give you the most efficient system. There is a computer modelling program available that aligns the Panels and there specification to the best inverter for that configuration, to go outside these recommendation will reduce your potential output.


Q: Is the income from a solar system taxed?

A: If it is on your primary place of residence the answer is no, if it is attached to your energy bill as your business account then the answer is YES, the system in this case will also a depreciate, you need to clarify this with your accountant if it’s for business purposes. We have attached the tax ruling for your perusal.


Q: How does the feed in rate work?

A: You will be paid a minimum of $.06 from your electricity retailer. We suggest you shop around and talk to the retailers to get the best price available. Your new digital meter when you install solar power will read your usage and input hourly, if you produce 8kw per hour and use 4 kw in that same hour you will be paid for that 4kw in that hour ($.24).

How much you will get as a return will be up to you, manage your usage on appliances during the hours of 7am till 5pm and you will be surprised at your possibilities.


Q: When do I get paid?

A: You need to request your payment preference with your Energy Provider, by the ¼ or Yearly.


Q: Does my roof need to be strengthened?

A: As long as your roof meets the normal building codes then normally no, but you need to confirm this on site inspection.


Q: Should I put a larger inverter on now so I can upgrade later?

Our answer is no, we match the inverter as closely as practical to the solar panel output. The reason this is so important is that the inverter actually uses energy from your panels to turn the DC from your panels into AC for the grid. The larger the inverter particularly on the systems under 5kw have different voltage needs to turn on your system and produce electricity back to the grid? Explanation:  Some inverters start producing AC back to the grid at 100Volts while others start at 150/240 depending on the quality of your inverter and its model this can vary a lot between systems. If your start up voltage is high on a bigger inverter the later in the day your system will start feeding power back into the grid, reducing your possible return. Simply put if it wasn’t so important why do they make different size inverters at all???? If asked to supply a system with a larger inverter we would decline the work as result of possibly reduction of the systems efficiency.


Q: Which direction should the panels face?

A: Ideally you panels should face north at the same angle as your latitude, Brisbane is 27 deg.


Q: Do I lose a lot of solar production if I am facing East or West?

A: You will lose up to 5/10 % if you can’t face north, if you want to increase your return tilt the panels north on your East or west roof this will reduce the overall loose.


Q: What happens in a hail storm?

A: The panels can stand a direct hit at 30 meters per second from a piece of hail 1Inch in diameter, if your panels are broken chances are so would your tile roof?


Q: Does the fact I have solar power attached to my home affect my Insurance and what should I do about my insurance?

A: When the solar system is fitted you need to advise your insurance company that your solar system is affixed to your roof; they will generally just add it to your policy at no added cost? You need to confirm this with your insurance company before you proceed.

Poultry Lighting & Power Factor

LED Lighting, Voltage Optimisation and Power Factor correction will significantly reduce operational costs, our observations have seen most sites running a Power factor of .72 to .88 which will see an increase of operating costs between 12% to 30% on most sites, our Voltage optimisation units, LED lights with built in sunrise sunset controllers coupled with our variable speed drives that operate the fans reduce power factor. VSDs will help stabilise the growing condition and improve returns, fans don't have to run at 1005 to get the best results through 80% of the growing cycle, if we reduce fans speed by 25 we increase savings by 20%.
Chicken farms are at the mercy of the energy providers and retailers, better energy supply and a controlled voltage equals better returns, less light failure, less burnt out or failing fans, less heat, and better overall growing conditions.
