How to select a solar panel to suit YOUR needs!

As electricity costs rise and the planet warms up, it’s time to start thinking along the lines of greener and cleaner energy while reducing your electricity bills.

If you’re feeling overwhelmed by all of the solar information out there, you’re not the only one! First and foremost, solar power is a long-term investment so there are many other aspects aside from the initial pricing that you need to consider. The solar panel cost is made up of a few different variables: the physical size of panels, the size in watts, the brand, the quality and durability of materials (including warranty period). Here are four steps to help you decide what’s right
for you:

  1. System output should match your consumption habits.
    The system size that you will be quoted is generally based around the solar power generation potential of your property – so you will need to work out how much electricity you use and when you use it. Look through past electricity bills to get an idea of this. A typical Aussie household uses approximately 20kWh per day, which equates to a 5kW system.
  2. What size solar panel does my home need?
    You want to make sure to install a system that is big enough to power all your household appliances, and ensure you have the space required to install it. The wattage of the solar panel is probably the most important thing you need to get right …as underestimating the number will lead to a lack of energy, and overestimating the wattage will lead to spending more money than you actually need to! Remember, it’s not the number of panels on your roof that matters, it’s the summation of each individual panel that  gives you your total output for the system. This number output should be near the size of your inverter.
  3. How much space do I need?
    Solar panels for households normally come in the standard dimensions of 1.70m x 1.00m (that’s around 1.7m sq for every panel installed). If you’re considering a 5kW system, expect something between 15 and 20 solar panels. This requires anywhere between 25 – 34m sq of roof space.
  4. Find a good installer.
    We truly mean this! Finding a quality installer is a really important part of the process, as solar systems are a complex piece of technology that most people don’t understand. So you want to be able to trust your installer and their electrical work. Look out for CEC (Clean Energy Council) accreditation and post-installation accessibility to your installer for any questions or queries you might have. You always want the company that sells you the system to have their installers internal to the company. Otherwise, you could get any tom, dick or harry installing on your property and they may not care as they are negotiated down on price to install. We all know you get what you pay for with a tradesman. A trick some sales companies try is that they claim they use their own installers. This may well be the case, so check that the company selling you the system has a current NSW electrical license with the name of the sales company written on it.
