Check your energy efficiency before installing solar
If you’ve been thinking about installing a solar energy system in your home, you might have collected your last energy bill and assessed the size of solar energy system your Melbourne home will need to accommodate your energy use. Perhaps your latest bill said your previous annual energy bill was $2,000 and you were using over 7kWh a day. When collecting solar installation quotes, you will have taken this figure into account assuming you need a system that will supply at least 7kWhs a day.
But what if your energy needs were smaller than you realised?
If you can increase the energy efficiency of your home before installing a solar energy system, you could decrease your energy needs and reduce the size of a solar energy system your Melbourne home needs.
Upgrade to LEDs
Lighting in the average home can account for as much as 10% of your home energy bill. If you’re using inefficient, energy-hungry bulbs like Edisons and halogen downlights you could be using 85% more energy on your lighting than you need to.
Did you know 95% of the energy used in an incandescent bulb goes into heating it? With an LED it’s only 15%.
A halogen downlight typically uses 30w, and an LED downlight uses 7w.
So by upgrading to LED, you could reduce your home energy use significantly.
Upgrade your appliances to energy efficient 5-star rated
Home appliances can account for as much as 30% of your home energy use. If you upgrade your washing machine, fridge, dryer and air conditioner to 5 star rated products you could reduce your current energy use through these items by 50%.
Upgrade your ceiling insulation
Half of the energy used to heat or cool your home can escape without proper insulation. This can lead to a considerable waste of energy. Air conditioning can be a colossal energy-guzzler, and without that cool air escaping through your ceiling and hot Australian sunshine pounding your roof, you could be throwing money (metaphorically) out of the window!
Upgrade your home insulation, and you’ll put an end to these energy leaks.
If you made these and more changes to your home, you could bring your home energy consumption down and reduce the size of the solar energy system you need. This will decrease the solar installation costs and payback return period for you and your family.
Why not check your interval bill and assess which periods of the day are causing spikes in your energy use and this might help narrow down what appliances are demanding the most energy.
