The new MASH system on our family home in Riddells Creek cost just over $7,000 for 5kW and features a top quality European inverter and high performance panels. It is amazing how far solar prices have dropped and how the quality has improved. Our electricity bills are around $3,200 annually. With the MASH installation, they are estimated to reduce by around $1,450 each year. That’s a payback of about 5 years, a decent return I reckon. What's more, with this MASH system we are reducing our family's greenhouse gas emissions by around 8 tonnes per year. This is equivalent to taking about one and a half cars off the road each year! If you've been thinking about going solar, have a chat to the MASH team about their local not-for-profit option.
