Standalone Solar Power Systems
Stand alone solar panel systems are completely independent of the grid. No more power cuts or electricity bills. The cost of a system depends on the energy needs of the house hold.
Click Here to download the solar power energy calculator Excel spreadsheet , so that you can work out your energy needs. Feel free to change or delete the columns to suit your own usage.
The final number in the table gives you your daily energy usage in Kilo Watt Hours (KWH). An energy usage of 2000WH would need at least 1000W worth of panels. This is worst case in mid winter and is based on conservative (safe!!) design equations.
Systems typically consist of:

Systems typically consist of:
- An energy source-ie, solar panels and a generator.lar panels and a generator.
- Batteries to store energy for use when the sun is not shining.
- A Regulator or controlled Solar inverter to ensure the batteries get charged correctly from the panels.
- An Inverter that converts the low battery voltage to 240V AC. This allows you to use normal household appliances.

Smaller systems ( 2KWH daily usage) are generally configured as DC coupled and larger systems as AC coupled. DC-coupled systems use a Regulator, such as a Victron Smart Solar MPPT, to control the charge to the battery.
AC-coupled systems use a Solar Inverter that supplies power directly to the main switchboard, and then excess after household usage is used to charge the battery
Grid Connect systems use grid power from the street but use solar panels to reduce the amount of energy used by the home or business. In New South Wales, under the current feed-in tariff, a well-set-up system will attempt to utilise as much of the solar panel's energy as possible before feeding any excess back to the grid.
You will generate approximately 4 kWh (units) of energy per day for every 1000 watts of panels. This will reduce your energy bill when the home can use this energy. As electricity prices go up, your solar system will save you even more money.
Any excess energy may be sold to your energy retailer (eg Origin or ACTEW) at their current buyback rate.

Solar Back-up Systems
Solar backup systems serve as emergency power sources in the event of a power loss. It has a few system features:
- The system automatically switches over to battery power in the event of a power failure to continue powering all or selected household circuits.
- Panels can power the system during a power failure for an indefinite time period, depending on battery size and panel size.
- The system can be programmed to run off batteries at peak tariff periods or whenever needed.
- The system will run until a predetermined level of battery discharge is reached. For example, till 60% state of charge each night.
- Recharges the batteries from the sun or grid (at off-peak rates).
- Limit exports or export to the grid. This can be useful when the existing cable infrastructure will not support a large system exporting to the grid.
- 63-amp (15KW) throughput.
- Different inverter sizes (24 and 48 volts, 3, 5, 6.7KW)
- 7 Year warranty on inverters
- Remote monitoring with PC via Bluetooth or CatV Cable
