Installing residential solar energy
Solar power is now the cheapest electricity available so installing a solar system is a cost-effective way to reduce electricity bills. Feed in tariffs also allow you to sell excess energy back to the grid. The average household can expect an investment return in 2-5 years.
“First thing to do is take a good look at your electricity bill. How much are you using and how much is it costing you? As a rule of thumb using 20kWh of electricity per day would equal a 5kW solar photovoltaic system.”
Next step is to choose an accredited trusted solar installer who guarantees their work. They will model your estimated annual electricity generation and expected savings.
Ensure your installer quotes on Tier 1 solar panels with a proven inverter. The inverter converts the direct current (DC) energy generated by the panels into 240V alternating current (AC) electricity to power your home.
The size and number of panels you install will depend on your daily usage and roof space. Solar panels should ideally face north, but can be placed east and west to catch morning and afternoon sun, and angled if needed to maximize solar capture.
Final steps are to upgrade your energy meter and choose a retail electrical provider that delivers you the best deal. Then each time you flick a switch, enjoy using your cheap and planet friendly electricity powered by the sun.
Mat Colefax’s residential solar success
In early 2020 the Colefax family installed a 6.6kW solar system on their home and Mat Colefax couldn’t be happier.
“Our system is right on track to generate the estimated 11,000+ kwh of electricity this year. And due to my careful selection of a local installer and quality equipment, the system actually saving us more than forecast, potentially delivering around 40% more savings!” said Mat.
Key selection factors for Mat were the brand quality & value of the panels, the inverter, and the solar system installer, along with guarantees.
“Our system was a financed one, with zero upfront deposit and quarterly payments of $387. So instead of looking at payback time, the key question for us was how much do we start saving from the second the solar system switches on, and how secure are those savings”
The Colefax’s are a family of five and their house has a pool. Pre solar, the Colefax’s previous annual electricity bill was around $2580.
Since installation, their quarterly electricity bills are now zero, with first and third quarter input credits from solar generation around $100-$200. Credit from the winter quarter was only $7, due to higher energy use from heating the house.
