In March last year, during the first couple of weeks of this blog, I posted this entry about our ‘big 3’ – the solar panels, solar hot water and rainwater tanks.
Today I finally received our statement from our electricity company for the meter reading which was done back at the end of November. This means that we now have the statistics for a full 12 month period of having solar panels and exporting generated power, which is excess to our requirements, back to the grid.
In one year of having our solar panels connected to the grid we will receive a refund of $1,244.33 as well as having $0 in power bills. This represents a total turnaround of costs over 12 months of $2,392.17. I am really pleased with the result as it was achieved despite one of the wettest summers on record (and next to no sunshine) in the first 3 months after the installation of the panels.
We have a 3.7kW system which cost nearly $14,000 after the rebates. We anticipated that we would recover our costs (in refunds and no bills) within about 5 years. We will go close to achieving this and my goal for the next year is to reduce our electricity consumption even further by being more vigilant in monitoring our usage. I will also endeavour to make sure that more of our necessary consumption is at night, thereby maximising the power being exported to the grid.
I am pleased that we can minimise our costs as well as making a positive contribution to reducing our carbon footprint.
