Off-grid Solar Power

Solar power systems for isolated houses, resorts, boats, farms, packing sheds, and anywhere that is running a generator.


 How many solar panels will I need ?

For every kilowatt of solar panels installed at the latitude angle, the following table will give a rough estimate of the power that you can expect.
Remember that shading, cloud cover, dust and pollution will affect the output of any solar power system.

To know what size solar system will completely run your house, look at the average kilowatt usage per day on the back of a recent power bill, then divide that number by the annual average figure in the table below.

Stand Alone (or Off-grid) Solar Power Systems

Often referred to as “off-grid” power systems, these are self sufficient systems that provide useable power to the end user, without the need to connect to a mains grid electricity supply.

They are common in remote and rural areas, where mains grid electricity either doesn’t exist, or is too expensive to have connected, due to the distance of the home from the nearest power lines.

Power is predominantly provided by renewable energy, such as solar or wind, which is then stored in deep cycle batteries. 

A pure sine-wave inverter then provides the 240 volt AC power for the house, and sometimes a generator provides backup power for when there is insufficient renewable energy available.

Solazone supplies solar power systems, lighting, pumps and refrigeration to those dependant upon solar power. 

Our experience over the past 30 years means we almost always have a great solution.

SP Pro Energy Centre - Standard Model Options 

The Energy Centre incorporates a battery bank which allows solar panels to continue powering your world when the grid has failed, while the batteries take over at night or when there is insufficient sun.    The result is clean continuous solar power under any conditions, which will allow you to take advantage of your local Feed In Tariff by feeding excess solar power to the grid during the day.    The entire process is automatic. In fact, the only complaint we have had so far is that our clients didn’t know that the grid had failed.
