successful bid price of rooftop solar storage project in New Zealand 2026

Is rooftop solar a viable option for energy supply?

Disclaimer: All estimates of current electricity prices used by both AMCL and EECA are intended to be representative, and all future prices are intended to be explorative. Residential rooftop solar photovoltaic (PV) generation is now one of the most accessible and cost-efective options to increase energy supply from renewable resources.

What is residential rooftop solar PV?

Residential rooftop solar PV provides a means for consumers to lower their electricity costs, particularly if they choose to move more of their household energy consumption to electricity. This is the first study in New Zealand to use detailed and high-quality data for both solar supply and residential demand.

Does residential roof-top solar PV cost more than utility-scale solar?

While the capital costs of residential rooftop solar PV are more than double the capital costs of utility-scale solar given in Table 13, residential roof-top solar efectively receives a higher price for its energy, in particular self-consumption, under the day/night price structure.

Can time-of-use retail prices improve the return of solar PV?

In the last section it was shown that time-of-use retail prices can, in some cases, improve the rate of return of solar PV with a battery compared to PV without a battery. However, the improvement is small and often occurs when there is a lower return for a system with a battery relative to one without.

How do I choose a utility-scale solar site in New Zealand?

Solar resource also varies widely throughout New Zealand and there are many potential sites for utility-scale solar across the entirety of New Zealand. Selecting and ranking suitable utility-scale solar sites would require matching the LCOE with prevailing locational electricity prices.

Is rooftop solar a good investment?

Assessing the economics of solar PV for 47,000 consumers in Auckland, Wellington, Christchurch, and Queenstown indicates that rooftop solar is an investment that can provide internal rates of return above 8% and sometimes as high as 11-12%, albeit varying substantially by demand profile as shown in Figure 1 below.
