Thanks for the support Howeph et al… much appreciated.

Any info on the unit? Scroll inverter?

There’s a spec sheet available for download here http://alexanderwatson.com.au/Storage/Solar-Air.pdf

Typically you’d only find scroll compressors on larger ducted systems, this one is just a standard inverter system.

So if you don’t use the aircon most of the time your wasting the solar panels… if you use the aircon more than you should then its likely a cloudy will have the unit using mostly grid power.

In winter there is no solar rays to power it at night, and usually its cold at night.

Doesn’t seem practice, you could spend $4000 on insulation and do a better job.

Totally agree, insulation and draught proofing are always the priority before adding in additional air conditioning. However, if you are going to go the the expense of putting in a split system you might as well put one in that can power itself when its most needed in Summer.

As for cloudy days in Summer, you probably won’t really be needing the AC on these days because the temperature is usually much more pleasant than a 30+ degree sun filled day. In Winter though you are bang on, at night time when you would normally use the AC there isn’t any solar gain. What you can do though in a well insulated home is actually run the heater during the day using the solar panels so the house is warm and (depending on how well insulated) retains its heat for the night.

Alexander Watson, don’t treat me like an idiot.

I have compared my summer electricity bills before and after installing the aircon, over a few years. A good quality unit like mine results in negligible differences in the bills. Trust me, I pay them, and get no funds from Big Aircon.

What you are offering is that first people pay for aircon, and then they pay for your solar units. And please, don’t wish away the $600 subsidy. It is paid for by consumers and taxpayers, not fairies and unicorns. And it directly benefits your business.

Wow, so much anger. Why?

Too much Bolt.

Alexander, you must know you’re doing something right when the cranks start spluttering at you.

Gosh, benefiting a small business? WHat an outrage!

Meanwhile, here is a list of subsidies that the taxpayer is paying for, to the benefit of Big Fossil-fuel:

– Fuel tax credits = $2billion pa
– Fossil fuel infgrastructure Accelerated Depreciation taxpayer ripoff= $120million pa
– Consumer subsidies for Kerosene, fuel oil, heating oil, aviation fuel = $1billion pa
– Electricity subsidies for Aluminium smelting = $200million pa
– Electricity subsidies to low income households = $200million pa
– Geoscience Australia, DITR & State energy Depts non-recovered costs = $200million pa
– Company tax deductions for petroleum exploration = $200million pa
– “R & D” = $88million pa
– Stuart Shale Oil project grants and royalty exemptions = $38million pa
– TImor sea project subsidies = $8 million pa
– Road transportation subsidy = $1billion pa
…and more

In 2010-2011, all this taxpayer ripoff added up to $12billion.

So if you don’t use the aircon most of the time your wasting the solar panels… if you use the aircon more than you should then its likely a cloudy will have the unit using mostly grid power.

What nonsense.

Whose sprouting the nonsense?

My state of the art reverse cycle Daikin unit makes almost no difference to my electricity bills in summer.

Heat-pump aircon systems are amazingly efficient, but still in the summer they are going to be one of your bigger electricity energy uses – unless your house has really good passive cooling systems (most don’t).

breda said :

Like diesel powered cars vs electrics, efficiency is not the issue here.

Hang on – then why did you bring efficiency up? No one mentioned efficiency before you did. What are you trying to say?

breda said :

It is all about “saving the planet” at our expense, and your profit.

Oh, I see. You’re a denier. A denier that thinks a small business making a profit is bad (only coal, oil and gas companies are allowed to make a profit – at our expense, and our childrens’, and grandchildrens’, and great grandchildrens’ and great great… ).

Got it.

breda said :

And, the $600 rebate is paid for by whom? It’s just a subsidy/handout for your business paid for by all the other punters.

Only coal, oil and gas companies are allowed to get subsidies too.

Any info on the unit? Scroll inverter?
