Solar Energy System – FAQs
1.How much will a solar hot water system cost?
Typically, a solar hot system will cost between $5,000.00 and $8,000, dependent on system choice, location and frost requirements.
2.How long will my solar hot system last?
Flat plate solar hot water systems have been around since the 1950’s. It’s a time tested technology and systems installed in the 1970’s are still performing efficiently today. We offer either a 5 or 10 year Limited Warranty, dependent on collector type.
3.How can I be sure of the quality and efficiency?
All solar systems are built to and comply with the joint Australian and New Zealand standard AS/NZ 2712.
4.How much money will I save?
Solar hot system can provide 70% and more of the average household’s hot water requirement. Most analysis suggests that approximately 50% of an average electricity bill is a direct result of water heating.
5.Does a solar hot system, really make an environmental difference?
You bet! The average solar hot system saves about 1.5 tonnes of carbon emissions a year.
6.Which type of solar hot system should I buy?
Kiwi Solar hot water system dealers will be able to offer advice on collector choice. The number of people in the family will determine the right size cylinder. Typically a 325 litre cylinder will cater for the average family’s requirements.
7.I’ve heard that solar systems don’t work in cold areas.
Not true. Kiwi Solar’s – solar systems work by way of solar radiation. With Kiwi Solar European designed technologies, there’s enough sunshine anywhere in New Zealand to power a Hot Water System. Once again we can help you choose the most suitable collector.
8.Can frost and snow damage a Kiwi Solar System?
The components of a Kiwi solar hot system are designed to withstand the rigours of northern European winters. Consideration must be given however, to the effect freezing can have on a system. Where frost is a common occurrence you’d be wise to choose a closed circuit system in which the water is heated via a heat exchanger and solar energy transfer fluid.
9.How much roof space does a system require?
These days most customers chose a split system which eliminates the need to place the cylinder on the roof and is probably more visually appealing. A typical kiwi Solar System includes four square metres of collectors.
10.Can I install a Kiwi Solar hot water system on a flat roof?
Yes, special brackets are available which support the collectors at a suitable angle.
11.My roof slopes at 45 degrees. Is this OK?
It’s just fine. In fact it will increase winter efficiency. In a perfect world, the collector angle would match the location latitude. But a flat plate system will work well from a pitch of 12 degrees on up.
12.Does my roof have to face north?
Ideally, yes. However it’s not critical. Kiwi Solar hot systems function well as long as they’re in a range between North East and North West.
13.I’ve heard that evacuated tube systems are more efficient than flat plate collectors?
Both EECA and the Solar Industries Association state that in New Zealand’s temperate climate both systems are equally efficient. So quality of construction, durability and aesthetics, should be the main considerations Kiwi Solar, solar hot water system has proven technology that comes up trumps every time!
