How much does it cost?

A good quality 15kW solar system costs anywhere from $12,990.

When choosing the system that’s right for you, remember price is a good indication of quality. You don’t have to spend the maximum amount to get the best results, but sticking to systems at or over this price range ensures you’re purchasing quality you can rely on.

How big is it?

A 13kW solar system consists of 36 to 38 solar panels. As they’re 1.65m x 1m in size, you’ll need a large roof space of between 67 to 90 square metres.

How much power does it generate?

An efficient, well-functioning 13kW solar system generates around 53kW of electricity per day.

However, how much power your 13kW system generates depends on two key factors – your geographic location and the orientation and angle of your solar panel array. You’ll generate more power in summer than in winter, and predictably sunnier locations yield better results than those experiencing higher cloud levels.

Regardless of your location, our installers will ensure your system’s positioned for the best possible results, ensuring you get the best possible return on your solar investment.

How much can I save?

If you consume most, if not all of the solar power your 13kW solar system generates, you’ll save around $800 to $1000 per bill cycle. Use the bulk of your power during the daylight hours and when demand and the price of electricity are high, and those savings will increase even more.

What’s the average payback period?

The average payback period for a 13kW solar system is between 3 and 5 years. However, you’ll start saving as soon as your system starts to generate energy, so the real savings begin upon installation.

What kind of household does it suit best?

A 13kW is ideal for very large households. If you use around 40kWh of electricity per day (mostly during the daylight hours), have reverse cycle air conditioning, a large pool, home automation, and an electricity budget of $800 or more, a 13kW system could be the perfect solution to your energy needs.
