Solar buy back
Most power companies will buy back your exported solar energy at a rate of 8 to 15 cents per kWh.

Effective 22 May 2025, Investment Boost enables businesses to immediately deduct 20% of the cost of new assets, including solar systems, from their taxable income.

After sale care
Monitoring, performance reporting and ongoing support for the life of the system.
Turn key or PPA
Two ways to fund a commercial system. The right one depends on whether you want to own the asset or preserve cash flow.
Turn key solar system
Own your solar system with a one-time capital investment (CAPEX). Ideal for businesses seeking full control, maximum return on investment and long-term electricity cost savings. You benefit from asset ownership, depreciation tax advantages and full energy independence. Our team handles everything from design to installation, using high-quality components built to last with minimal maintenance required.
PPA (Power Purchase Agreement)
Pay zero upfront. We fund, install and maintain the solar system, and your business simply pays for the power you use at a lower, fixed rate than your current electricity provider. No capital outlay, no maintenance risk. This is the perfect solution for businesses wanting to reduce operating costs, lock in energy prices and preserve cash flow while switching to clean, reliable solar power.
| Comparison | Turn-key | PPA |
|---|---|---|
| Upfront cost | High | $0 |
| Ownership | Customer | Provider |
| Maintenance | Customer | Provider |
| Monthly payment | None | Lower rate |
| Tax benefits | Yes | No |
| Long-term saving | Higher | Moderate |
