About this installation
The client is a commercial business with high daytime electricity usage, operating primarily between 7:00 AM and 6:00 PM. Power consumption drops significantly in the evening and overnight.
With rising electricity costs and a strong commitment to sustainability, the client opted to install a large-scale solar PV system to reduce operational expenses and improve energy resilience.
Because the load profile is concentrated in daylight hours, self-consumption is high and very little generation needs to be exported, which is what makes the payback on a system this size so short.
Estimated performance
| Metric | Estimate |
|---|---|
| Annual solar production | 235,000 to 255,000 kWh |
| Self-consumption rate | 90% or more, based on load profile |
| Estimated annual savings | $60,000 to $70,000 NZD, based on $0.26/kWh |
| Payback period | 4.5 to 6 years |
| Expected system lifetime | 25+ years, with minimal maintenance required |
Figures are estimates based on the site's load profile and modelled generation. Actual output varies with weather, shading and how the household or business uses power.
Estimated payback and bill saving
Estimates prepared for this property before installation. We prepare the same modelling for every quote so you can see the payback before you commit.
In the homeowner's words
Thinking about commercial solar?
We model the same numbers for every commercial enquiry: generation, self-consumption, annual saving and payback, based on your own load profile rather than an industry average. Businesses can also deduct 20% of the system cost upfront under the IRD Investment Boost.
Backed for the long run
Expertise and customised solutions, high-quality components and technology, and a commitment to sustainability and customer satisfaction.
