This depends on your roof space and the size of the inverter. If you have sufficient roof space and additional capacity in the inverter you could increase the size of your system. Or you could add a second system to your roof. Please note: At this time, the solar Feed-in Tariffs in each state have limits on the system size which to they apply. Increasing the size of an existing solar power system could affect your eligibility for a Feed-in Tariff. Please call us for further information.

If your solar panel system is connected to the grid, it will shut off in the event of a blackout. This is to prevent emergency responders and electricity utility repair-people from being injured by your panels sending power back to the grid. However, there are certain inverters you can buy that provide backup power in a blackout when paired with a battery.

It’s easy to check your solar power system at any time. The majority of inverters offer a built in display that gives you a live data feed of how much power your system is generating. Most systems will give you historical data showing how your system has been performing over time. If your solar inverter is wi-fi ready you can see your performance through web application on your mobile.

The easiest way to find out how much you pay for electricity (and how much electricity you use per month) is to take a look at your utility electricity bill. Alternatively you can call Solar Mentor to guide you reading your electricity bill to find out exactly what you use, need and have to look for.

It's hard to say about average installation time without knowing the size of solar power system. Bigger the system, longer the time it require to be installed. Let's take 5kW system for installation which takes around 3-5 hrs, start to finish.

Since this depends on how long approval takes, it varies state-to-state. South Australia currently has the fastest meter approval and installation timeframe of 1-2 weeks. Western Australia is the slowest at about 4-8 weeks.
