FAQs 6

Are solar panels more energy efficient than inverters?

It is very common in Australia for the total capacity of solar panels in an array to be the same as the capacity of the inverter. This has the advantage that energy will never, or almost never, be lost because of the panels producing more power than the inverter can use. But this is not much of an advantage.

How much solar power can a 5kw inverter produce?

Under the Clean Energy Council rules for accredited installers, the solar panel capacity can only exceed the inverter capacity by 33%. That means for a typical 5kW inverter you can go up to a maximum of 6.6kW of solar panel output within the rules.

Should you install a rooftop solar system with a larger inverter?

Installing rooftop solar systems with a total panel capacity greater than the inverter capacity is usually a very good idea. It will certainly save you money, but it can also help get around the restrictions many Australians face on the size of inverter they can connect to the grid.

How does a solar inverter affect efficiency?

The efficiency of the inverter drives the efficiency of a solar panel system. Inverters change the Direct Current (DC) from solar panels into Alternating Current (AC), which is what we use in our homes and businesses. This article talks about how to pick the right size solar inverter.

Should a solar inverter be oversized?

However, slight over-sizing of the solar panels compared to the inverter capacity (up to 133% under certain guidelines) can sometimes yield better overall efficiency due to the variable nature of solar irradiation throughout the day. The ratio for inverter sizing often depends on specific system requirements and local regulations.

Should I install an inverter on my solar panel array?

Installing an inverter whose maximum capacity is greater than the nominal capacity of your solar panel array may be an option if you’re looking to expand your solar panel array at some point in the future, but it is not generally recommended.
