Frequent questions: 13 kW solar

Western Power may restrict inverter capacity in certain network locations to no more than 10 kW inverter output capacity.

Most leading inverter brands state that their inverters can endure solar array oversizing by up to 50%. The Clean Energy Regulator has had its say on this topic and capped the oversizing of solar inverters to 33% without a battery.

Therefore, 10 kW Inverter capacity (10) ÷ 0.75 = 13.33 kW of solar panels.

Increase savings potential and improve system efficiency by overdriving your inverter ›

This depends on you. A 13 kW solar energy system with a 10 kW inverter will generate an annual average of 60 units (kWh) per day, but we can estimate maximum saving potential through historical irradiance data and Synergy tariff prices.

Therefore, consider a maximum energy saving potential: The ability to consume the maximum annual estimated yield on a Northern roof aspect (0°) with a 25° roof pitch, located in Perth (6000) and environmentally derated to 70% generation potential, your energy savings substituting the Synergy Home Plan A1 tariff in 2024/25 of 30c per kWh would be similar to: 

13 kW = $4599

The above is a maximum saving potential using a general (central) installation profile to assist in determining a best-case return on investment in annual energy savings.

Suppose you choose to opt out of a battery. In that case, these savings reflect unobstructed daylight hours within a variable solar bell curve period, 8 am to 5 pm, and are presented as unit-for-unit savings, which may not directly reflect bill savings.

It’s important to note that every installation is unique and requires a location-specific energy yield report for more solid investment decision-making. We’ve made getting your free yield report easy. Request a noninvasive express quote, and we’ll send your complimentary energy yield report.

Yes. As with all 10 kW solar systems, battery choices are limited. For example, if the only battery you want to install in the future is a Tesla Powerwall (AC coupled), then selecting any standard (solar only) inverter will work.

Although, should your preference be a Sungrow SBR HV (DC coupled battery), a compatible hybrid solar and battery inverter such as the Sungrow Hybrid (SH RT) inverter is required.

Using a $38 STC (Small Technology Certificate) valuation and 440W solar panel size for multiplication, the solar rebate you can access in the Perth and Bunbury region of Western Australia for common solar energy system sizes is as follows:

  • 13.2 kW = $4,852 – 2024 installation
  • 13.2 kW = $4,159 – 2025 installation

For your convenience, advertised Perth Solar Warehouse 13 kW solar package prices include the subsidy already deducted as a ‘point of sale discount’ (redeemable by Perth Solar Warehouse after installation to recover the total system cost).

If you would like to take advantage of the current year 2024 solar rebates, Perth Solar Warehouse provides a hassle-free, noninvasive express quote for your convenience.

Systems greater than 5kW inverter capacity are exempt from the Synergy Distributed Energy Buyback Scheme (DEBS). Here’s our overview: Navigating The Synergy Solar Feed-in Tariff With Ease.

Feed-in tariff or none, solar energy is most valuable when used directly or stored in a battery for later use. Consider a battery and ensure your new energy saving appliance does the whole job.
