Bit late, but we've got a 30 tube/250L electrically boosted system. Here in Canberra (more like Christchurch weather, hotter in summer though) we don't need to boost Sept->Apr. We've got a timer switch in the fusebox for the electric boost, and it comes on from 5.00-6.20pm, and it will top it up if we've had a poor solar day.
We have hard frosts, so the tubes make much more sense here. People on various enviro forums reckon you get a much bigger surface area for panel systems for the same cost, so if frost isn't an issue this is a better way to go. Also the integrated thermosiphon jobs are very well understood, very low tech (I've been quoted $1000 to replace the controller on our system, which is outrageous. I wouldn't pay that, but it gives you an idea of what some are paying). Don't write off flat panel systems, but I don't know enough to recommend any.
Your water use patterns matter a lot. If you all tend to shower at the same time of day it helps. We scrub the kids in the evening, but the adults are morning showerers. This means the tank is half full of cold water overnight. It is supposed to stratify and not mix too much, but it still has an effect.
We tilted our tubes up to 50deg, as we have an over-production in summer, but our shoulder and winter production was disappointing. There was a substantial improvement after tilting, with the added bonus of less over-heating and venting in summer. A wetback + solar system would be a great combination, as a solar system sized for summer will struggle in winter. Sized for winter it is likely to be expensive and still struggle on very cold dull days.
We average about 5kWh/day electricity usage in Summer, 8 kWh/day in winter.
We also have a 1.5kW PV system. This produces about 2/3 of our power, but as we got in when there was a generous FiT, we don't pay power bills, they pay us.
CAUTION: PV does not like shade! If there is ANY shade on the panels your output will be substantially reduced. The cells turn into resistors when shaded, so well designed panels have by-pass diodes that, as you may have guessed from the name, bypass that section of the panel. All it needs is a small part of a panel to be shaded to bypass a much larger area of panel: there is a limit to the number of bypass diodes. Upshot of this is you can have a quarter of your panels shaded, but get a 75% reduction in output. It depends very strongly on the geometry of the panels and how the shade interacts with that geometry.
If you have significant shading from 10am-3pm I think PV would be a mistake.
I understand thin-film PV suffers less from shading (and possible also better in overcast conditions), but I haven't done any significant research into that.

Sorry to be a pain, but another weird coincidence, I married a Kennard (not in NZ), Names eh? Maybe not as rare as I'd imagined ...
Off topic, but my Grandmother was also named Winifred Beatrice (b. 1910). No connection to this story, but just an odd coincidence.
Does he always issue such terse replies or just seeking to deny oxygen/not get caught in lie?
Is there no mechanism for a "question on notice" or require an undertaking for the PM to actually make some enquiries with departments etc to find out actual information?
Because stock market bubbles are so much better than property market bubbles.
Note that Germany has rules about corporate governance that give workers input into the running of the company. Apparently this is a major reason German companies are "valued" less on the stock market. I don't know if this would tend to suppress some bubbly aspects of the stock market, but as it has already depressed values it clearly has some dampening effect.
Note that the firms themselves are no less profitable or valuable in toto, it's just that some of the value is held collectively in the form of employee control.
I'd also point out that capital investment does not equal buying shares on the stock market. Companies issue debt or extra shares to raise money for economically useful purposes. The role of government is to set policy to make it more attractive to socially useful stuff with the money than bid up the price of housing in inner city Auckland.
Germany has low net wealth, half that of Greece & France, less than a third of that in Spain. Weird eh? Turns out a good deal of this is due to rules and regulations that favour capital investment over fetishistic home ownership
Wealth is a social construct. Policies can change wealth, which can change investment incentives.
Maybe high house prices are a result of secular stagnation. If so, those other articles might hint at approached to reconfigure the incentives to make capital investment more attractive.
That is some awesome work.

Jay Rosen was pretty scathing of the Newsnight Interview
He even got Ian Katz, the Editor of Newsnight, responding. Still wasn't impressed.
Bunging someone 2 hour postpartum into a car is a seriously bad idea.
Not only is it uncomfortable, it could well be seriously dangerous. A friend had a massive bleed a couple of hours after her second birth. It was life threatening even though she was in hospital at the time.
Good to hear all went well (not counting the earthquake thing).
