Are Solar Panels Worth Investing?

For those who are seeking cleaner energy sources, harnessing the power of the sun could be one of the best options. Of course, the prospect of cutting down energy bills through the latest developments in solar energy is a great idea. But the initial investment can make you think whether solar in Sydney is really worth investing? Well, to understand how you can be benefited from solar energy, the solar panel efficiency must be considered.

What You Need To Know About Solar Panel Efficiency

Solar panel efficiency is one of the significant factors you need to consider when shopping for solar panels. So, what is solar panel efficiency? Well, it is a measurement of solar panels’ ability to convert the sunlight into electricity that can be used. According to research, solar panels are roughly between 15% and 18% efficient. Yes, while 15% to 18% of the sunlight is converted into electricity, rest hits the solar panel and warm the surface. The higher the efficiency rating, the more sunlight the solar panel could convert into electricity. That said, there are a lot of factors that affect the solar panel efficiency.

What affects the solar panel efficiency?

Solar panel efficiency is affected by several factors, including the solar panel materials, solar panel age, and the type of solar panel.

The type of solar panel

Thermal and photovoltaic panels are the two types of solar panels. While thermal panels capture the sunlight and operate efficiently in warm climates, photovoltaic panels separate electrons with the energy from sunlight, and then the electricity is used to power the house. Photovoltaic panels are commonly used for residential solar.

Solar Panel Materials

Monocrystalline silicon, polycrystalline silicon, and multi-junction solar cells are the three major solar panel materials. Monocrystalline silicon is the more common and efficient material.


If sunlight is reflected away from a solar panel, the efficiency of the solar panel will be reduced. That’s why the glass layer on top of the panel is important.

Average sun exposure, solar energy system design, solar plans, and regular maintenance are the other factors that influence the efficiency of your solar panels.

As you see, the solar panels you choose determine the solar panel efficiency, and it is indeed worth investing. Get help from the professionals while choosing the solar panel for your house.

Know the Advantages of Rooftop Solar Panels

Are you thinking about going green? Installing solar panels on the roof top is a great way to cut your energy expenses and save more power. Solar panel on the roof also reduces carbon emissions and minimises your dependence on fossil fuels. Below we’ve compiled a few benefits of installing solar panel on the roof.


Solar power systems harness the power of the sun, and by installing them, you are reducing your carbon footprint and increasing renewable energy generation.

Reduce Your Utility Bills

When you get solar power systems installed on your rooftop, you can reduce your energy bills. The amount you will save depends on the size of the panel and your electric usage. Installing solar panels for the house not only helps you in reducing your electric bills but also grants you income for any surplus power you generate by supplying it to the grid. It’s termed as ‘feed-in-tariff’.

Increase the Value of Your Property

Installing a solar power system to your rooftop increases the value of your property. For example, if you install a solar panel of 5kW, it could add approximately $29,000 to the value of a house.

Low Maintenance

Generally, solar panels don’t require a lot of maintenance, and all you have to do is to keep them clean. In addition to the initial cost of installation, you can expect minimal spending on maintenance and repair work.

Save You from Power Outages

When you rely on the electricity supplied by the power grid, you are susceptible to the power outages experienced by the grid. However, solar system for home has a battery system for power storage and use, so you will not lose power during a power outage. It will continue to supply power to your building’s electrical system for as long as the sun is shining and your battery backups are functioning correctly.

Low Installation Cost

Unlike other systems, solar panels are incredibly affordable. Nowadays the costs have reduced by a whopping 23% comparative to the last five years. You can also now finance your solar panels with a loan, buy it outright with cash, and more.

Solar energy is a reliable source of power, and you can count on it for your residential or commercial use. Make sure to choose designs that adhere to any rebates or incentives that you may wish to use to help you make your panels more affordable.

Top Reasons to Accelerate the Shift to Green Energy

Due to the COVID – 19 pandemic, many countries have imposed strict lockdowns and other restrictions to prevent the spread of the virus. This includes travel restrictions, business closures, work-at-home options, and more. The virus has also made a great impact on the energy sector. According to the World Resources Institute, Global energy use is predicted to fall 6% over the course of 2020.

Climate scientists also have told the BBC that the Covid-19 pandemic is a “huge opportunity” to fast-track Australia’s shift towards green energy. Reports also add that the use of renewables is increasing in Australia year-on-year and in the last year, 24% of all electricity generated came from renewable sources.

A Nationwide analysis from live monitoring systems shows a 105% increase in Aussie household electricity in Q1 2020 as compared to 2019, a spike resulting from the lockdown of the Covid-19 pandemic. But, homes that have solar power systems are more likely to save money on their bills.

So, if you are thinking about choosing green energy for your residential or commercial property, here are a few reasons to go solar.

  • Installing solar power systems helps you to generate your own energy and frees you from depending entirely on energy companies to brighten up your residential or commercial premises. When combined with high energy battery backups and storing of excess energy to use during emergencies, this makes your household more self-sufficient instead of relying entirely on energy from the grid.
  • With solar rebates and other plans available, you can get flexible financing options that cover solar power systems prices and allow you to save money in the long run.
  • When you install solar power systems, you can offset high energy usage and save more on utility bills.
  • Solar panels are eco-friendly, harness the energy of the sun to power your home or business without contributing to local air pollution.
  • Solar panels have a long life span of 40 years and can be recycled once they reach the end of their life.
  • Solar energy is a true renewable energy source that can be harnessed in all areas of the world and is available every day.
  • Solar energy can be used for diverse range of applications from electrical energy to heat energy.
  • It requires less maintenance, as you only need to keep them relatively clean to maintain its maximum efficiency.
  • Solar panels are silent and do not emit polluting gases.

The Bottom Line

Solar power is 100% clean and reduces your dependence on oil, coal and natural gas for electricity production. It also eliminates the emission of harmful gases that affect the quality of air, water & soil, which are responsible for global warming. So, now is the right time to go solar and we are here to help every step of the way.

What is Solar Rebate and How to Claim It?

Australia receives more sunlight and has a mix of favourable conditions to support the choice to switch to solar power. The mostly sunny climate makes solar panels more productive and increases the savings per kilowatt-hour produced. Australia also has solar rebates that make solar panels affordable and easier to buy. The national solar rebate benefit applies for solar panels, solar water heaters and heat pump systems.

Australian Government Solar Rebate

Some Australians believe that the Australian solar rebate ended in 2019, but this isn’t true. The Government has lowered the rebate amount slightly, but it continues to run until 2030. Reduction in rebates is a normal part of the rebate plan and depends on the total energy output between the years in which the solar system starts operating and the end of 2030.

Small Scale Technology Certificate

A solar system gets a Small scale Technology Certificate for every 1,000 kilowatt-hours of estimated production. Large solar panel installation in Sydney and solar systems in sunny places get more STCs.

New South Wales Solar Rebate 2020

In addition to the Small-scale Renewable Energy Scheme, there are many other incentive options available at different states and territories. The New South Wales’ Empowering Homes program provides loans up to $14,000 for solar battery systems and up to $9,000 for adding batteries to existing solar PV systems. This benefit is available for households with an income of $180000 per year. Another incentive program on trials in New South Wales is aimed at Solar for Low Income Households, and it offering to give 3-kW solar systems to 3000 homes in specific areas of NSW. This program is available to most people except for holders of a Pensioner Concession Card or a Department of Veterans’ Affairs Gold Card.

Eligibility Criteria for Solar Rebate

  • The solar installation must be done 12 months before STCs are created.
  • Must meet Australian standards of solar panel installation and any local requirement at the state, territory, or municipal level.
  • Use solar panels approved by the Clean Energy Council
  • The maximum installation capacity must be 100kW, and annual production must be less than 250000 kWh.
  • Solar panel installation must be done by a Clean Energy Council accredited solar contractor.

How to Claim Solar Rebate?

Depending on the program, the requirements for a solar rebate in Australia vary, and you must get approval for your solar system before beginning the installation process. You can find the installation and documentation requirements from the Australian Clean Energy Regulator to earn STCs. Depending on the STCs, you can choose between a registered agent or claim & sell on your own. However, you can claim a large rebate upfront when you choose a registered agent. When STCs are claimed and sold by the solar system owner, the financial benefit is spread between the year of installation and 2030.
