Rooftop solar – recent experiences in Canberra?

By cranky 29 July 2015 29

Thinking of installing solar power to our house. Orientation is ideal, and whilst not looking to make money, I would love to escape the clutches of ACTEW (or whatever they’re called this week).

Would appreciate any feedback re: supply and installation of (say) a 4Kw system, and how it has performed.

The majority of advertisers on Google require many personal details which do seem excessive. The one that has put their price out there is in the vicinity of $5600, a reasonable figure I assume.

Appreciate any comments, including thoughts on the whole technology.

What’s Your opinion?

Wish the rebate was back and we could have this at our new place !

You mean “subsidy” don’t you?

Oi! Get yer own drum to bang, that one’s mine!

Seriously, though, I’m lucky enough to own an investment property – and the deprecation on the solar panels is probably at least almost as good as any FIT.

Southmouth, we run the large power hungry heaters all day (1 split system aircon and 2 x IXL cavity 4+kw wall heaters), as we often have someone at home during the day. All night we run smaller plug in heaters (read uneconomical heaters). We try to run the washing machine, dryer and dishwasher in daylight hours, but not exclusively. We wanted to see how well the solar would benefit us if we did not conform to regimented power usage. Our house is old and poorly insulated, and we don’t have double glazing.

I’m impressed. I would have thought that the low feed in tariff and electric heating would have made net positive bills impossible. Well done.

I installed a 5kw system that feeds power I don’t use back into the grid (net feed?). It cost me $7200, which includes $1400 to entirely replace the mainboard and cabinet it fits in, as it was not large enough to accommodate the new meters. Our entire house runs on electricity, except for gas hot water. Having all electric heating is crucial in getting the best return on solar. Despite only a 7c feed in tariff, we have power bills that are in credit to us since its install. We would see the system break even in 3 – 4 years.

What time of day do you run your electric heating and for how long?

Just to clarify if you are concerned about not wasting energy then grid connected batteries is a far better solution. the idea being that you can load share across the grid removing the extreme peaks of mornings and evenings. PIf everyone went off grid it would require significant amount of redundancy into everyone’s energy storage.

Grid connected storage is the key focus of companies like Tesla with their Powerwall product and there is already talk of suburbs/communities chipping in for a local level storage solution. This combined with solar is a great win for everyone.

It’s worth remembering too that Canberra company Reposit power is in the final stages of testing a system where you’ll be able to sell your energy through them as a broker on the National Energy Market at much higher rates than the FIT.

In the UK, double glazing is about as scam filled as Nigerian emails. Don’t think for a moment that the standards work there.
