Sizing your system

*Outputs based upon average Australian solar irradiance conditions and PV performance of ~4kWh/kWp per day.


Electricity Usage
Average 4-person family in Australia uses 15-25kWh per day, or 5475-9125kWh per year.


Hydronic Space Heating
Tractile Solar Tiles are used in conjunction with hot water tank and heat pump technology.


Pool Heating
For pool heating the surface area of the pool equals the required area of solar roof tiles (-20%~ +20%).


Electric Vehicles
For electric vehicles a daily travel range of 55kms to 80kms can be charged from approximately 3kWp of PV (18sqm of Tractile Eclipse Solar Roof Tile).
