How does solar energy work?

In a nutshell, solar panels work by capturing particles of light and converting them into electricity. If you want to know the nuts and bolts of how solar works, you can find a more detailed explanation here.

How does solar battery work?

Solar batteries work by storing the excess energy your solar system creates so you can use it when you need it. By storing your excess solar, you can maximise your savings and negate any unreliable supply issues by always having a backup energy supply in your battery. We are a qualified System Provider with South Australia’s Home Battery Scheme.

What brand of solar panels and inverters do you use?

The solar panels we use are all Tier 1 high-quality panels. We use several brands including Seraphim panels, Solis inverters and our own Grand Group panels. If there is a particular brand you would like to use, we can source these for you. At the end of the day, we want you to be happy with a solar system that best suits your needs and circumstances.

What size solar system do I need?

The answer to this question isn’t so simple and will depend on a number of factors related to your energy usage, roof pitch and size. We offer free assessments by our trained assessors to help determine the best solution for your needs.

How much will it cost me to install solar?

The cost to install your solar system will depend on the size and type of system installed as well as any other complicating factors (difficult access, etc.) for installation. We will provide you with a full quote, including an explanation of any eligible incentives once we have assessed your energy usage and house location.

Do you offer flexible payment options?

Yes, we can offer financing to help you manage the cost of your solar. There are a number of payment options available to you, each of which can be discussed at your free assessment.

What warranty do you offer on your solar panels?

Depending on the panels we install, we offer a warranty of up to 25 years.

Will my solar system require a lot of maintenance?

The benefit of using systems that are of the quality we use at Grand Group, is that there is minimal maintenance required. When we install your solar system, we will give you information about how to maintain your system. It’s really important you follow the information we provide to ensure optimum performance of your panels.

Are your solar installers licensed?

As a Clean Energy Council Approved Retailer, we only use CEC Accredited Installers for our installation. Our team are all licensed and accredited so you can be sure your solar install is in safe hands.

How long will it take to install my solar system?

For straightforward installations, our crew can have this completed in 1-2 days. However, we will do a thorough site survey and engineering review before we commence installation so we can give you a more accurate time frame. Larger commercial or business installations can take longer depending on size, complexity and any special mounting requirements.

Where will my solar system be installed?

For most home installations, the roof is the best place to install your solar system. The space where the system is installed will need to be unobstructed by trees and facing toward the north to capture the most sun. If your roof isn’t suitable, we can look at other options such as ground-mounting the panels, but the roof is the preferable location.

How much is the solar rebate?

There are essentially two ways to access incentives for solar. Through our free assessment process, we talk you through each of these to explain how they work. Your eligibility for Small-scale Technology Certificates (STC) available through the federal government's Small-scale Renewable Energy Scheme is based on a number of factors including the size and location of your system. You may also be able to take advantage of feed-in tariffs whereby your energy company gives you credit on your energy bill for any excess solar energy you feed back into the grid. This tariff varies based on your location and the energy company.

How big are the savings with solar?

The savings with solar will depend on a number of factors including the size of your system, how big your energy bill is and how you use energy in our household. We offer a free assessment where our trained assessors can help to calculate the potential savings based on your individual circumstances.

Are you a member of the Clean Energy Council?

Grand Group Australia is a Clean Energy Council Approved Solar Retailer. While it is easy to become a member of the Clean Energy Council, becoming a CEC Approved Retailer is much more difficult… and it is something we are very proud of. As a CEC Approved Retailer, we must comply with a rigorous code of conduct to ensure we are providing top quality solar solutions to our customers.
