The pros and cons of solar roof panels

More and more Australians and businesses are installing solar power. According to the latest figures, there are nearly 2,000 Mount Isa solar roof panel installations. Solar roof panels have their pros and cons. Let’s look at the advantages first.

The pros of solar roof panels

  • They can save you money on your power bill by converting natural sunlight into energy that you can use instead. Energy prices have risen substantially in Queensland and the rest of Australia over the past year.
  • You can export any surplus energy to the power grid if you are connected to the Ergon or Origin networks and you meet the legibility requirements. The current feed-in tariff for these energy exports from Queensland regional areas like Mount Isa is 9.3 cents per kilowatt hour.
  • You will be reducing your greenhouse gas emissions, which is better for the environment.
  • Solar power systems with battery storage can provide back-up power during blackouts.
  • They can add value to your home if you’re looking to sell or make your investment property more attractive to potential tenants (due to lower energy bills).

The cons of solar roof panels

  • There is an upfront installation cost unless you opt for a solar power purchase agreement over several years, a solar power loan or you lease a system. If you don’t pay upfront, you will pay more overall.
  • Solar power can be an intermittent energy source if your system doesn’t have battery storage.
  • Solar roof panels require significant roof space with access to direct sunlight.
  • A solar system powers electrical appliances only, so if you use gas for your hot water or cooking, it won’t reduce those costs.
  • Some low cost systems may also be low quality. Do your research before you buy to find an approved solar retailer. Look for warranties from approved, established and reputable suppliers.
  • If not installed correctly, solar roof panels can be a safety risk and can also void your home insurance. Make sure you use a licensed and experienced solar panel installer.
  • The manufacture of solar panels has some environmental impact, though not as much as the ongoing use of fossil fuels.
  • You can’t take solar panels with you if you decide to sell and move (thought they may add value to your home).

Solar roof panel FAQs

How much do Mt Isa solar roof panels cost?
According to the latest government figures, the cost of a basic installation on an average-sized home without battery storage starts at around $3,500 if you pay upfront.
If you want battery storage, your system will cost more.
Larger solar power systems can cost up to $10,000.

How long does it take for you to save on the installation cost?
Again, according to the latest government figures, the payback time for a basic, low cost system without batteries is 3 to 5 years. The payback time is longer for a more expensive system with battery storage or larger systems.
You need a rooftop that’s fully exposed to sunlight for as long as possible to get the best results in terms of both power savings and exports back to the grid.

Most solar panel systems have a 10 year product warranty and a 25 year performance warranty. You should keep your panels clean to ensure optimum performance.
