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 annual performance
| Metric | Estimate |
|---|---|
| Annual energy production | 235,000 to 255,000 kWh |
| Self-consumption rate | 90% or more, based on load profile |
| Annual electricity savings | $60,000 to $70,000 NZD, based on $0.26/kWh |
| Estimated payback period | 4.5 to 6 years |
| System lifespan | 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.
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.
