Sydney in New South Wales is a great place for solar power, and roughly 10-15% of Sydney area homes have solar panels installed on their roofs. New South Wales which originally comprises more than half of the Australian mainland.
If you are searching for a guide on how to compare prices and what to consider before purchasing solar panels in Sydney, NSW then you are at the right place.
After reading this guide you will figure out the answer to the question People often ask Before Getting Solar Panel Installation in and around Sydney.

When you buy rooftop solar panels for your home, you can spend as little or as much as you like. The more solar panels you have, the more solar will save you.
“The average residential solar system offsets about 100,000 lbs. of carbon dioxide in 20 years – the equivalent of driving a car for 100,000 miles.”
If we talk about prices,
Solar panel prices can range widely, however it mostly depends on the size of the solar power system.
Residential and commercial solar power systems can start as small as 1.5kW and can go above 50kW.
The solar system perfect for your home depends on your expectations on price, quality, and service.
The following questions decide Solar Panel Prices & how much price you have to pay…
- How much do you want to spend on a solar power system?
- How much roof space do you have to install the panels?
- The size system has your energy retailer approved you for?
- What level of service meets your needs?
- The quality of parts and installation do you expect?
As energy prices around the country soar and concern about electricity bills mounts, solar panels are increasingly being installed by homeowners wishing to take advantage of a system that produces greener energy and insulates them from rising energy prices. But what do you need to know before installing a solar photovoltaic (PV) system on your roof?
How Solar Photovoltaic or PV systems do works?
Solar photovoltaic (also known as solar PV) systems convert energy from the sun into electricity. You can save money by harvesting this free electricity. Solar PV systems can be relatively simple, with their main components being solar panels or modules. Read on to find out more about solar PV systems, including which type generates the most electricity.
Basic types of PV Cells
- Monocrystalline cells tend to be more efficient than polycrystalline cells (13-17% efficiency).
- Polycrystalline cells can be cheaper than monocrystalline cells but are a bit less efficient (11-15% efficiency).
- Hybrid cells combine crystalline cells with another cell type, called thin film. This makes the panels even more efficient (17%+), but they cost more.
How Solar panels work?
We can change sunlight directly to electricity using solar cells. Every day, light hits your roof’s solar panels with photons (particles of sunlight). The solar panel converts those photons into electrons of direct current (“DC”) electricity. The electrons flow out of the solar panel and into an inverter and other electrical safety devices. The inverter converts that “DC” power (commonly used in batteries) into alternating current or “AC” power. AC power for your television, computer, and toasters use when plugged into the wall outlet.
Cells, modules, panels, and arrays
Most solar cells are made of silicon. Solar panels, also called modules, are each made of several solar cells, connected together and sandwiched between protective glass and a backing plate, the whole panel usually surrounded with an aluminum frame. All the tested panels have 60 cells except the Sunpower which has 96. The solar panels we’re testing weigh around 18 to 19kg each. A typical installation includes several panels connected together in an array.
Types of Solar Panels
Monocrystalline panels are typically black in color and have a reputation for higher efficiency than multi-crystalline (or polycrystalline), models
Interdigitated back contact solar cells (IBC), or rear contact solar cells, are a variant of standard solar cells. They can achieve higher efficiency by having all the electrical contacts on the rear of the cell (rather than at the front), so there are no metal contact strips preventing light getting to the cell surface.
Printed Solar Panels or Thin film solar cells made up of a thin layer of photovoltaic material (such as amorphous silicon, cadmium telluride or copper-indium-gallium-selenide) on a base plate of glass, metal or other substance. This a Next-Gen Technology and evolving and its usage are rare.
Solar Panel Efficiency
More efficient panels will tend to cost more. Before taking the dive and buying expensive panels, it’s worth also taking the size of your roof into consideration.
If you have enough space, cheaper, less-efficient panels could end up being more cost-effective over time. However, if space is limited, you would probably want to maximize efficiency to get more power out of your few panels.
Correct installation is also important; that’s why panels should be installed in a way that allows air to circulate underneath the panels to help keep them cooler.
Solar panels work best when they’re north facing, pointed directly at the sun, at an optimal angle and not blocked by trees or shading. The effectiveness of solar panels also depends on where you live and the weather
Choosing an Installer
Look for an accredited company that is a signatory to the code of conduct, has been in business for a while and has an established track record, relevant experience, specialist expertise, and a good reputation.
Questions to ask a potential installer and energy retailer
- Will you need to change to a new meter and what will it cost?
- What is the cost of the electricity you purchase from your retailer (in cents per kWh), and will you lose your off-peak rates if you install solar?
- Will you be charged a higher daily fixed charge if you connect your solar PV system?
- Do you have to pay any additional fees?
