Further Cost Considerations

Federal government rebates exist for eligible applicants, ranging from $1,700 – $30,000 depending on how much renewable energy is included in the final system.

Renewable Energy Fraction
Maximising your renewable energy sources will minimise ongoing generator costs.

Equipment Placement
For sites that do not have a suitable enclosure to house our AdaptUnit then the EnergyBox might be required at an additional cost.

Off-Grid Power System Load Profile

To accurately design your ideal off-grid solar system and provide you with a quote, we need to understand your property’s power usage.

We do this by asking you to complete an Energy Load Profile in which you list all the appliances and utilities that use power with an estimate of their usage amount. Once this is completed, we can recommend the best system design and size for you.
