Generation guide

Is a 10 kW solar energy system ideal for you?

Purchasing a solar energy system that matches your average daily consumption profile is important. As a guide, a 10 kW solar energy system ideally suits an average daily energy consumption of 25 kWh (units), factoring in a 5 kWh (units) tolerance. That means if you’re consuming up to 30 kWh or 20 kWh per day, or even lower, a 10 kW solar energy system may be an ideal solution. 

There are a few more individual factors to consider, but we’ll get to that shortly.

Customers should always obtain site-specific average generation report. To obtain this, contact sales support.

Storage guide

If you consume all of your power during the day, a battery will be less of a consideration. However, if 50% of energy consumption or more is unavoidably evening consumption, a battery completes the likelihood of bill reduction success.

But size matters! For example, a Tesla Powerwall provides 13.5 kW of storage capacity, approximately half of a 10 kW solar energy system’s daily generation (10 kW = approximately 30 kWh per day).

Your ideal battery size, more often than not, depends on your evening power use.

EV charge guide

One of the greatest variables is how much charge will your electric vehicle require per day to be powered by the sun effectively.

A recent internal study found a moderate daily commute required approximately 10 units per day. Topping this up daily from the sun in smaller fractions has benefits such as lower energy costs (considering both petrol and grid electricity resources).

In this graph, the EV charge guide (10 kWh) is added to the sum of the Powerwall storage guide (13.5 kWh).

Frequent
10 kW solar
questions.

In certain instances, yes. An advertised 10 kW solar package price has a base installation and product combination criteria.

1. Structure: The listed prices refer to single-level, three-phase and single-roof face dwellings with adequate switchboard accessibility/provisions available to accommodate the additional circuitry or associated components. 

2. Product/ package: The base nominated price uses an SAJ R5 (8 kW) inverter within PSW Installation Zone 1 after the STC Zone 3 subsidy has been deducted as a point-of-sale discount. Additional installation costs may apply to ensure this package meets your specific expectation.

For the 2024 calendar year, eligible Perth and Bunbury region customers within STC Zone 3 receive a $2426 point-of-sale discount (subsidy) when installing 10.5 kW of solar panels on an 8 kW inverter. An amount that reduces annually.

Based on 102 Small Technology Certificates, a system incorporating 24 x 440 W solar panels and a $38 STC market value.

102 STC’s x $38 value = $2426 subsidy.

For your convenience, the PSW Energy 10 kW solar package prices include the subsidy already deducted as a point of sale discount (redeemable by PSW Energy after installation). 

Systems greater than 5kW inverter capacity are exempt from the Synergy Distributed Energy Buyback Scheme (DEBS).
