What solar power system will suit my circumstances?
The average consumption in today’s family households consumes between 20 and 30 KW/h of electricity per day. Single person households can consume less than 10Kw/h per day. Please check the rear of your electricity bill as in many cases it will show average daily consumption.
A 2 to 3 kilowatt system in many areas of New Zealand can provide about a third to half the electricity needs for a family of four.
Please keep in mind that when you for example consume 5000 kW/hrs at electricity a year and you choose a system that generates 5000kW/Hrs per year – you will not be bill free. The reason is that you will still pay for the electricity you use at night and during rainy days. The extra electricity your system generates during the day, given the lower feed in tariff now a days, will not completely cover the cost of the electricity at night.
Nevertheless your solar system will help reduce the impact of increasing electricity prices.
