Want a 20 year discount on your electicity bill?

Your home is always going to need electrcity so why not get solar and save yourself the pain of huge and ever increasing electricity bills. With a suitably sized solar system you can reduce your electicity costs for the next 15 to 20 years.

Don't become a victim like I found when I went to the dentist recently. The dental nurse had a sour taste about solar salesman as she was sold a system for over $7,000 and the net result was a $50 per quarter reduction in her power bill when she had been told the bill would be neutral. We do the maths so you benefit from the right solution and we're willing to say if its not feasible for you.


Want to run on solar at night too?

A growing trend in new solar installations is to add a battery storage solution. This is to store your excess solar generation during the day for consumption at night with the added bonus having power during blackouts!

On-Grid Solar FAQ

Click on any of the below common queries to reveal its content.

How does solar power work?

The most common form of solar is grid connect systems. They are panels and an uncomplicated inverter either single or three phase that generates power for your premises while there is mains power available.

The inverter changes the DC power to AC and so that it takes over the supply of electricty to your house it pushes that power in through your switch board at a higher voltage than what is comming from the grid. It effectivly holds the grid power back.

This higher voltage also allows it to push the surplus power your house is not using back through the meter into the gird.

To charge batteries requires a Hybrid inverter or charge controller that directs surplus power into batteries and then manages the use of that stored power when the sun is not shining.

How does solar save me money if I only get a few cents for selling it to the retailer?

A grid connect solar power system takes over the supply into your house while it is producing power. Effectivly you get paid full retail price plus gst for this power you consume yourself. Secondly the amount of power you buy from the grid goes down. It is a combination of these 2 factors that makes solar economic sense. Hence the term FREE power. The bonus is the credit you get for surplus that you push back into the grid.

If I buy solar is there anything I need to do with my power retailer?

Any surplus AC power you generate that is not consumed in your premises is fed into the grid. You should negotiate with your power retailer for the highest price they will pay you for this surplus generation, This offsets the premium you pay them for what they supply you when your solar is not generating.

Your alternative is to store that surplus generation in batteries for use at another time.

Is it worth having wifi and a smart meter?

Wifi is a convienent way to check if your system is working!

Your electricity bill will show you how much power you draw from the grid when your solar is not able to generate enough. It will also itemise the surplus amount of power you send back to the grid from your solar panels. It does not show you self consumption and this can be confusing for people to comprehend when looking at their power bill. That is why it is a good idea to have an inverter with wifi that shows self consumption.

A smart meter also monitors the grid power consumption and time of day you are using it. Technical minded customers use this information to micro manage there power consumption.

What is the difference with a quality inverter?

In all manufactured products the components are rated and costed on the “expected hour life” of the components. The difference in price and quality of an inverter is determined by the hour rating of the components.

Cheap components are generally less efficient as they get hotter and require better cooling. The cooling component is an area where the cheap inverters also reduce cost, BUT the off set is that poor cooling reduces the life expectancy of the inverter. Those few dollars extra upfront for a better quality inverter can deliver many more kilowatt hours over the life of the system and give trouble free service.
