I purchased a 3KW Micro Inverter Solar system from the sponsor of Map of the Day, What Power Crisis, back in March and now it’s been running for a while I thought I’d share my experiences over a few articles. Although What Power Crisis did me a decent deal on the system, I’m not being paid to write this.
I bought the system with 3 aims:
1) Cut my power bill which was heading towards $2800pa
2) Get payback on my investment within 10 years
3) Not make life miserable by compromising on comfort and convenience.
I’m not a believer in the great man-made global warming/climate change conspiracy so changes in CO2 emissions didn’t factor into my decisions. Even if this was a concern, much more than half of New Zealand’s generation already comes from renewable sources, so replacing one renewable source with another, especially as it has to be manufactured in the first place, no doubt using fossil fuels, won’t make that much of a difference in my book.
Having run the system since 25th March with an extra couple of panels added recently I’m on track to achieve my targets.
I never measured the power use before I embarked upon renovations so the $2800 is the before-solar cost of a renovated 60’s house, with a DIY solar-heated pool setup and a new well insulated small spa. I can’t quantify how much cheaper the house is to run per month due to the renovations, but it is much more comfortable than before with no mould or damp. We usually wear T-shirts all year round, and the lowest recorded temperature without heating in the living area is 16 degrees.
Cutting power use is the cheapest way to shrink a bill! Read more »
