Solar Battery and Ducted Air Conditioning for Two Adelaide New Builds in Dernacourt
These two newly built Adelaide homes share the same mirrored floor plan, but the owners had different expectations for heating and cooling performance.
Rather than applying the same package to both properties, Energy Loop considered the comfort preferences and energy requirements of each home separately.
The Project
Each home received a complete energy system that included:
-
19.95kW solar system with 42 × 475W LONGi panels
-
SolaX three-phase inverter
-
43.2kWh SolaX battery storage
-
Daikin three-phase ducted air conditioning
-
Electrical planning for the home’s major energy loads
Although the solar and battery systems were similar, the ducted air-conditioning capacity was selected differently for each owner.
Same Home Design Different Comfort Preferences
🔹Home A was fitted with a 12.5kW Daikin ducted air-conditioning system. This provided a balanced solution for the home’s layout and expected usage.
🔹Home B was fitted with a larger 14kW Daikin ducted system because the owner preferred faster heating and cooling response.
This project demonstrates why system selection should not be based on floor plan alone. Two homes can have the same size and layout but still require different solutions because of room usage, comfort expectations and the way each household plans to operate the system.
One Connected Energy Plan
The ducted air conditioning was considered together with the solar, battery and electrical systems.
The 19.95kW solar system provides substantial daytime generation, while the 43.2kWh battery stores available solar energy for use later. The inverter output, battery capacity and ducted air-conditioning demand were reviewed as part of the overall system design.
By planning the major energy systems together, each home received a solution designed around its own comfort requirements and future electricity use.
Project Outcome
-
Two mirrored homes with individually designed comfort solutions
-
12.5kW Daikin ducted system for Home A
-
14kW Daikin ducted system for Home B
-
19.95kW solar and 43.2kWh battery storage for each home
-
Solar, battery, air conditioning and electrical demand considered together
Planning a New Home Energy System?
The same floor plan does not always mean the same energy solution.
Energy Loop designs solar, battery storage, ducted air conditioning, heat-pump hot water, EV charging and electrical systems around how each home will actually be used.
