Off-Grid Solar Power

Off-grid, Stand Alone (or Remote Area) Solar Power.

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

Stand Alone Solar Systems

We have built lots in remote and rural areas, where mains grid electricity either doesn’t exist, or is too expensive to connect to, due to the distance of the nearest power lines (it can cost several thousand dollars per power pole).

Power is predominantly provided by a renewable energy source, solar or wind, which is used directly or stored in large, deep cycle batteries.   A sine-wave inverter then provides 240 volt power to the household, and often a generator is used as a backup, for bad weather, or when there is insufficient renewable energy available to recharge the batteries.

Solazone supplies solar power, lighting, pumps and refrigeration to those depending upon solar power, since 1983.

During this time solar power systems have become larger, safer, and much more reliable. There are now Australian Standards that fully cover the design and installation of solar power systems, ensuring they are safely designed and installed, and operate effectively.

Currently Solar rebates apply for these systems, so the savings can amount to tens of thousands of dollars.  However, there is a political cloud on the horizon this year, so if you’re considering an off-grid solar power system, it would be prudent to act quickly to ensure the rebate still applies.

What are my power requirements ?

We are often asked to quote on solar power for a “standard” house.   Energy needs of every house is different, but to give you an idea, we have included some scenarios below.

If you want a solar system that works, you must ensure that it’s large enough to generate sufficient power for your needs, AND it must provide enough storage in the batteries to last you through periods of bad weather.


We complete a simple power calculation for each client – it takes some time and a bit of thought – but it results in you knowing what you’re getting, what the solar system is designed to do, and any  limitations built-in.

We all want the biggest and best solar system, but due to cost constraints, sometimes a compromise is required.   For example, with less solar panels, you may have to run a generator when using the washing machine, during rainy weather.

Use the sizing calculator below to estimate your power needs.  People are often surprised by the first results of this exercise.  Don’t be put off, just review the figures and try again.

That is how we determine the best size for your solar power system.

Email or fax us your load figures, and we can provide you with a detailed report, including the ideal battery size, and number of solar panels required for your solar system.
