Top 5 Common FAQs About Solar Panels In Auckland


Are you considering switching to solar power in Auckland? If so, you’re probably brimming with questions about solar panels, their functionality, installation costs, efficiency, and maintenance. 

To help you dispel any doubts and gain clarity about using solar energy, we’ve compiled a list of the Top 5 common FAQs about Solar Panels in Auckland. These will provide you with the necessary groundwork before you make the transition towards this sustainable, eco-friendly energy option. 

Are Solar Panels Worth It In Auckland?

Analyzing the worthiness of solar panels in Auckland involves considering several key factors such as the high annual sunshine hours, the continuous increase in electricity rates, and the environmental benefits. 

To begin with, Auckland receives an average of 2000 annual sunshine hours, which is considerably high. These sunshine hours can efficiently be converted into a reliable source of energy, thus minimizing reliance on other costly sources of power. 

When considering the escalating electricity prices in Auckland, investing in solar panels can indeed be a sound economic move. With solar panels installed, households can generate their own electricity, dramatically reducing their monthly power bills. 

Aside from that, excess energy generated can be sold back to the grid, making it a worthwhile investment in the long run. The use of solar panels significantly mitigates the household’s carbon footprint since solar energy is a green renewable source. As such, it contributes beneficially towards environmental sustainability.

Is There Any Subsidy On Solar Panels In Nz?

In New Zealand, the government recognizes the importance of renewable energy and its role in combating climate change. Therefore, there are several incentives and subsidies available for those interested in installing solar panels. 

One notable program is the Energy Efficiency and Conservation Authority (EECA) that offers a variety of beneficial funding options. While they may not directly subsidize the purchase of solar panels, they provide low-interest loans to homeowners to help cover the costs of installation. 

Some regional councils also provide additional financial support through targeted rates programs, where the cost of solar panels is added to property rates over a period of time. In addition to this, the government supports net metering, a system where solar panel owners can sell surplus energy back to the grid, thus reducing the overall cost. 

However, it’s crucial to understand that these subsidies and incentives tend to vary by region and are often subject to change. Therefore, it’s recommended to check the latest information from local councils or renewable energy advisory services before making any significant investment in solar technology. 

The subsidies might not always cover the full cost of solar panel installation, but they do significantly reduce the financial burden, making solar power a more viable option for a wider range of households and businesses across New Zealand

What Is The Average Power Bill Per Month In Nz?

In New Zealand, the cost of power can be a significant portion of a household’s monthly expenses. According to figures from the government, the average household in New Zealand consumes approximately 7261 kilowatt hours (kWh) of electricity per annum. 

The current mean price of electricity, as reported by Canstar Blue, is approximately 32.5c per kWh. Doing the math, this equates to a total of around $2360 per year, or when broken down to a monthly figure, approximately $196 per month. 

These costs can vary considerably depending on various factors, including the appliances in use, the number of occupants in the home, the energy-efficiency of the home, the specific region and the energy consumption habits of the household. 

Despite these variations, this figure still offers a realistic baseline indication that can be useful for households in planning their monthly budgets. Keep in mind that this is just an average figure, and homes with higher energy consumption could face significantly higher charges.

How Many Solar Panels Are Needed To Power An Average House In Auckland?

Determining the number of solar panels needed to power an average house in Auckland requires a few considerations, primarily revolving around the average energy consumption and the climate. 

The average Auckland house uses about 7,000-8,000 kWh (kilowatt hours) annually. Given that the city has an estimated annual sun hour average of around 4.4 hours, the throughput of the solar panel, which is typically about 300 watts per panel, also becomes vitally significant. 

Consequently, if one panel generates around 1.32 kWh daily, it translates to about 481.8 kWh yearly. Therefore, to meet Auckland’s average annual household energy requirement, approximately 15-17 solar panels would be necessary. It is, however, crucial to note that these numbers can vary significantly. 

Variables such as the specific energy requirements of a household, the efficiency of the solar panels utilized, the direction and angle of panel installation, potential shading, and other location-specific factors can all influence the number of required panels. 

Hence, while the average number provides a useful framework, individual circumstances often necessitate a tailored approach for optimal solar power generation.

What Is The Return On Investment For Solar Panels?

The return on investment for solar panels can vary greatly depending on a number of factors including the cost of electricity in your area, how much sunlight your home receives, and the cost of the solar panels and installation. 

However, the average payback period is generally between 5 to 10 years. After that everything is essentially profit, as you are generating your own power and not buying from the grid. Additionally, solar panels can also increase the value of your home. 

It’s important to remember, though, that while solar panels can certainly save you money in the long run, they require an upfront investment that can be fairly significant. Furthermore, the efficiency of solar panels can diminish over time, but most manufacturers guarantee a performance level of 80% even after 25 years.


The transition towards renewable and sustainable energy sources like solar power is not merely a trend but a necessity for the welfare of our planet. As inhabitants of Earth, it is our responsibility to reduce our carbon footprints and strive for a cleaner, greener future. 

By investing in solar panels in Auckland, we don’t just benefit personally, but we also contribute positively to our environment, establishing a legacy for future generations.
