How much does solar oversizing cost?

When designing your system, a good rule of thumb is that your solar panels should be 10-20% larger than your inverter. In hot climates, that can be extended up to 30%, due to greater efficiency losses from heat.

How much can I oversize my solar inverter?

133%
You can ‘overclock’ your inverter by up to 133% and still receive financial assistance in the form of Small-scale Technology Certificates, or STCs, as part of the Solar Rebate. But if you go even 1 Watt over the 133% limit, your application for STCs can be refused.

Can you oversize a solar system?

An Oversized Solar Panel System Will Produce “Excess Power” It is possible to include additional panels with no power being lost. Also, the additional panel capacity helps the inverter to run at a higher efficiency which can almost make up for what is lost.

Is it better to oversize an inverter?

In fact, some tests have shown an increase of up to 28% daily energy yield with an oversized inverter. This extra panel capacity will do wonders for the environment, your power usage, and your running costs!

What size inverter do I need for a 10kW solar system?

They do go hand in hand though. If you are single phase home in the most common distribution areas across Australia, to install 10kW’s of solar you will need to install an 8kW solar inverter or two 5kW solar inverters.

What is inverter oversizing?

What is Inverter Oversizing? As we mentioned further up, oversizing solar inverters refers to when you install a solar array (that’s a group of solar panels) with a higher capacity than the rated size of your inverter. Basically, you install more solar panels that your solar inverter capacity is meant to handle.

Why does a 6.6 kW system have a 5kW inverter?

Typically, a 6.6kW system comes with a 5kW inverter, due to panel efficiency losses and because some network distributors do not allow you to install an inverter greater than 5kWs in size. So, you do not need to pay any more for an inverter. You still receive your rebate on the additional 1.6kW of solar panels.

What is the best brand of inverter?

What happens when you overload a solar inverter?

Having your solar panel overload isn’t a bad thing though. In fact, you want the panel to be able to take on a greater amount of energy than what the inverter can handle. The worst that will happen is the panel stops working and slows down power dispersed throughout the system.

What if I generate more solar than I use?

If you produce more solar power than you use (as will be the case for many customers during daytime hours, especially in summer) then your system will feed power out to the grid.
