Why Choose Illuma Electrical Group

Why Choose Solar & Batterie's

  1. Why should I install Solar?

Switching to solar renewable energy will save you hundreds or thousands off your electricity bills each year, add value to your home, reduce your carbon footprint and help to build a cleaner future for generations to come.


  1. What is the difference between a grid-connected and off-grid power system?

Grid connect systems use solar generated power to supply your house appliances then supply power to the grid or battery if you have one installed, and only source additional power from the grid when the sun goes down or your battery is empty.

An off-grid or stand-alone system is when you store all the energy your panels produce in a battery and generally have a generator for emergency backup. A battery is required for this application.


  1. What rebates are available?

A state government rebate for Solar is available for home (up to $1,400) or battery ($2950) and business (up to $3,500). To learn more visit Solar Victoria


  1. How do I know if I’m eligible for a Rebate?

To determine your eligibility visit Solar Victoria

  1. How do I apply for a rebate?

Your solar retailer will start the application for you then an email will be sent to you with the information you need to complete your application.


  1. What size system will I need to run my home?

The size of a Solar System is determined by the amount of power you use in your home, the orientation, and the amount of space on your roof to fit the solar array. We are experts in this area and will advise the best system to suit your needs.


  1. How long does it take to install Solar?

Once your Solarvic application is complete and you get an email back with your qr code we normally contact you to book in a date for installation. Once the date is set, we normally complete your installation in one to three days depending on your systems design and size.

  1. How long do Solar Panels last?

Solar panels are made from Silicon and our preferred brands can last over 25 years if properly maintained. We offer premium solar products that come with a 25-year warranty if you budget for this option.


  1. Do I need a battery to store the energy produced?

You will only need a battery to store solar energy if you are not home during the day or you dont have any loads you can run during the day.

For an off-grid or stand-alone solar system you will need a Battery and potentially a generator.


  1. Will installing Solar panels really help to reduce carbon emissions?

Generating electricity from solar panels produce no greenhouse gases whatsoever, which helps to reduce the effect of climate change. When solar energy is powering a home or business, there is no burning of fuel and no emissions from energy production once installed.


  1. Does roof orientation matter?

North facing panels are the ideal position for generating power consistently throughout the day.

East facing panels result in most of your power generation produced in the mornings.

West facing panels capture the afternoon sun discuss these options with bill


  1. What is a “feed in tariff” and how much will I get paid?

feed in tariff is a small credit rebate received for any excess electricity produced by a solar system. If you have a grid-connect solar system, power produced may be used immediately by your appliances or it will feed into the shared electricity grid for other properties to use.

For each kilowatt hour (kWh) of electricity exported to the grid, that property will receive a feed-in tariff of a few cents, usually between 4 and 6 cents per kWh.


  1. What type of warranty comes with the system?

Warranties come with all of the systems we install and range from 10 years up to 25 years depending on the solar product chosen.


  1. If my energy requirements increase, can I upgrade the system?

Yes, you can upgrade your existing solar system. Contact us to learn how we can help you to achieve a seamless upgrade.


  1. What happens on cloudy days?

Solar panels still work on cloudy days and when it rains, however the power being generated is reduced.

  1. Will I need a new switchboard and/or meter?

The age of your home can determine if you need a new switchboard or meter. Our team will investigate and advise if you require an upgrade before we install any products on your home.


  1. What happens with grid connected systems during a blackout?

When there is a black out, a home with a grid-connected solar system will also be without power. By law grid-connected solar systems must be shut down if the grid loses power. This is to ensure linesman can repair any faults safely Unless you have a hybrid battery system which will supply power to a few chosen circuits.


  1. How much roof space do you need?

Every Solar system we install is custom designed to match the home’s unique size, shape, and roof dimensions. The actual amount of space needed depends on the size of system being installed, which dictates the number of panels required.


  1. What is the difference between solar power and solar hot water?

Solar hot water systems, sometimes called solar thermal systems, use the direct heat from the sun to heat water, whereas solar panels use Ultraviolet Rays, sunlight to produce electricity.

  1. How do we store solar power for use after the sun goes down?

The only way to store solar power (generated during the day) for use at night, without reverting to the grid, is via battery storage. Our team can provide extensive information about the use of battery storage in your home.


  1. Is there any maintenance required?

We provide our customers a maintenance proposal after we have completed the installation.

Panels should be cleaned from mould, dirt and bird droppings ideally every six to twelve months.

It is recommended to have your Solar System checked annually to keep performance at its peak. Contact us to arrange a professional maintenance check.


  1. Can you insure a solar system?

Most home and business insurance companies will cover the solar power electric system as part of your insurance policy. In many cases this addition to your policy should not increase the premium.
