What solar power system will suit my circumstances?
The average family household consumes between 20 and 30 KW/h of electricity per day. A single person household can consume less than 10Kw/h per day. The back of many electricity bills will often show your average daily consumption.
A 6 kw system in many areas of Australia can provide a significant part of the electricity needs for a family of four. Our solar calculators on this site via lets you work out the best solar system size for you.
Please keep in mind that, if for example, you consume 5000 kW/hrs at electricity a year and you install a system that generates 5000kW/Hrs per year you will not be entirely bill free. The reason being 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 is generally given the lower feed in tariff and will not completely cover the cost of your night time electricity consumption.
The arrival of solar storage batteries has changed this paradigm when it comes to offsetting night-time energy use. Your capacity to store power in a battery is at the moment capped at sub 13kW (nett 11kW of storage). At current cost of power, ROIs are more than 10 years - about the life of high quality batteries. Prices however are dropping regularly and storage capacity is increasing. We recommend monitoring battery costs and discussing your needs with an LG Authorized Partner.
There are long term large battery storage units in development that can store up to 1000kWh. They will enable you to store extra solar generated in summer to use in winter and on rainy days. However, they are currently cost prohibitive and large in size and so will remain so for the next 5 plus years at least.
