Is this solar system right for your home or building?
A 15kW solar system can suit very high-use homes, home offices, workshops, small commercial buildings and properties preparing for electric vehicles and battery storage, subject to network approval.
- Larger homes and commercial buildings with daytime loads can often use more solar directly.
- Sites with evening loads, demand peaks or backup needs may benefit from battery modelling.
- North, east and west roof areas can all be considered during layout.
- Shading, roof material and switchboard condition affect the final design.
- Export limits and network approval can influence inverter selection.
- A recent electricity bill helps us size the package properly.
