There are lots of different reasons why you may be considering solar. Of the thousands of systems we’ve installed over the years, in every part of the New Zealand, it typically boils down to one or more of these four factors.

They are:

  • You want to reduce your power bill and you are looking for a meaningful payback or ROI (Return on Investment). After X number of years you want to know that the system has paid for itself, so you can enjoy paying only a fraction for power compared to what you paid before going solar.
  • You like the idea of power independence. You like how modern ‘hybrid’ solar systems (with battery storage) can provide emergency back up power – almost like a mini-off grid system. You want peace of mind in the event of short-term or even long-term power cut. You may even see global geo-political disruption as a risk factor and want to explore self-sufficiency.
  • You may be retired or thinking about retirement, and you like the idea of reducing your living expenses and investing in solar while you still can. You understand that power prices will never come down, and you like the idea of having a small power bill. For you it’s not just about the fast financial payback.
  • You are concerned about climate change, and want to do your small part to contribute to the health of the planet.

…or it may be a combination of these reasons. 

If financial ‘payback’ is your driving motivation, then it will take longer with battery storage compared to installing panels alone.

Solar panels alone (with no batteries – but the option to add them later), has the fastest financial payback because the price is lower. Typically you could save about 40-50% off the power component of your power bill when averaged over the year.

With hybrid battery storage, your savings *could* be as high as 80-90%, however your payback period will be longer.

Every household is different, but you can talk to one of our Solar Designers who can crunch the numbers with you over the phone and discuss your options (you’ll need a copy of your power bill handy).

If your motivation is purely financial, we may even recommend that you do nothing (if the numbers don’t stack up).

It costs nothing to find out if solar is right for you.


Of course everyone’s power bill is different. It depends on a dozen different factors as to what you pay each month.

According to different sources, the ‘average’ family home in Auckland will use about 30 kWh per day, when averaged over one year. If you are a single person or couple, or are running an efficient home, it could be much less.

Likewise, if you’re running a spa pool, electric vehicle (EV), multiple heat pumps or other high draw appliances, then of course it will be much higher – especially in winter.

If your power bill is low compared to the average home (say under $150 per month in winter), and your motivation includes having a quick financial payback, then adding batteries may not make sense for you.

If your power bill typically averages over $200 – $250 per month or more, and fast financial payback is a priority for you, then battery storage *may* be viable for you.

In item #1 above, we talked about people having different motivations that are not always about the financial payback. Even if your power bill is low, this doesn’t exclude you from having battery storage. It just means the financial payback will be longer.

To find out about your options, go ahead and talk to one of our Solar Designers over the phone – as long as you have a recent power bill handy, we can usually give you options at the end of the call.


For some homeowners it can be difficult to say with certainly if they’ll be living in the same house in 5, 10 or even 15 years down the track. For others who are living in their ‘forever home’, it’s a lot simpler.

While this may not be the driving factor for you in your decision to install solar and battery storage, it should still be considered.

Making an investment in solar then selling up in 12 months time may not be an issue if Auckland property prices continue to rise, but the overall value of your solar investment will be lower compared to someone who lives in their home for 15 years.

With more than 15 years design life on modern, quality battery banks, and 25 year performance guarantees on most quality solar panels, the longer your system is used, the more value you’ll receive.

It’s common sense.

But even if your home is a ‘stepping stone’ property to another in the future, this shouldn’t exclude you from considering solar.

Again, it comes down to the importance you have on maximising payback vs independence and sustainability.

Very few people will do a ‘return on investment’ analysis when buying a car because we accept that a car is a liability, not an asset.

Although the financial benefits of solar will be important to most of us, every year there are more people starting to value the other advantages of solar over and above just the financial payback.

Because everyone is different, you can have a no obligation chat to one of our Solar Designers who can help you to decide if it’s right for you.



Your ‘power use profile’ are the patterns of daily life and power use in you home, from season to season. These patterns can influence how your solar system is designed. 

Some of these patterns include:

  • In winter, who is at home using power during the day? Do you leave for work when it’s dark, and return home when it’s dark?
  • What is the family/occupant makeup? The ages of any children and other lifestyle factors should be considered.
  • How is your hot water, cooking and heating powered?
  • Are there cost-effective ways to improve your home’s power efficiency right now, including reducing thermal loss in winter?
  • Are there ways to ‘load shift’ and use appliances during the daytime when power is ‘free’, e.g, dishwasher and washing mashine?
  • Is your power use likely to reduce, stay stable or increase in the future?

And more.

Investing in battery storage could make sense if a significant portion of daily power consumption is after dark. That’s because the excess portion of power generated by panels during the day can be diverted to the battery bank for night time use.

Understanding how these factors impact on *your* solar design, will make sense after a short phone meeting with one of our Solar Designers. 


Without a suitable roof (or space for a suitable ‘ground array’), a solar system just won’t work.

It’s not just a matter of whacking up some panels and hoping for the best. That’s why there’s a proven process including computer modelling, that we use to check the viability of your overall solar solution.

That process is not just a list of boxes to tick. Your home and power profile will be different to every other family on your street, and there are nuances and potential pitfalls to consider.

We can explain them to you.

Here are just some of the factors to consider when it comes to roof suitability and system sizing.

They include:

  • The exact number of panels you’ll need is based on your daily power use, particularly in winter. Once we know the number, we can check your roof space to see if they will fit. Usually, a system that includes battery storage will require more solar panels, to allow the battery bank can be filled during the day in winter.
  • Can panels be oriented to the north, or as close to north as possible? While it’s possible to have a ‘split array’ where some panels are facing east and some face west, this can add to the price and complexity of your design.
  • Even in Auckland, solar panels should ideally be racked up to 20 degrees (or maybe more) to cope with lower sunshine hours in winter. In Auckland in winter, solar noon (the highest the sun is in the sky) is only 29.7 degrees above the horizon, so this needs to be taken into account. If your north-facing roof is pitched (a gable or hip roof) and there is sufficient space for panels, they can be laid flat on the roof.
  • Monopitched (flat) roofs will require solar panels to be racked up with special tilt-legs. This can add to the price of your system.
  • In Auckland, there are a wide range of roof types from corrugated iron, Coloursteel, concrete tiles and more. Different roofs require different approaches to mounting and different design strategies

And more.

Remember, roof suitability goes hand-in-hand with the size of your system, and the size of your system always starts with your power use (your power bill).

It’s tempting to guess how many solar panels you might need after watching a few YouTube videos and talking you your neighbour who has solar.

Fortunately, we don’t have to rely on guesswork because we have the tools and deep experience that includes computer modelling combined with data on official sunshine hours for Auckland.

You don’t have to figure it out on your own.

    I am very impressed with the way SolarKing have handled the project. The installation was carried out by SolarKing installers for whom nothing was too much trouble, who made a very good job of the installation (which did present them with a couple of challenges) and left our place so tidy you wouldn’t know they had been here.

    The efficient way you have coordinated everything and responded to our requests has been appreciated. If you could pass on our thanks to all concerned I would be grateful. It’s nice to find a company that takes customer service seriously.

    Andrew, Bay of Islands

    I have found SolarKing very easy to deal with, right from the first time I contacted them to inquire about installing a solar power system I have found their staff members punctual, knowledgeable and reliable.

    The installation team worked quickly and thoroughly and the solar system was connected to the grid soon after it was completed.

    I would thoroughly recommend SolarKing to anyone contemplating installing a solar power system.

    Bill, Auckland

    We would like to thank you for installing our solar system.

    Your company has been professional from start to finish including keeping us informed every step of the way on progress and paperwork. Also please pass on my thanks to your installation team who did a very professional install and completing the others items we requested.

    I will have no hesitation in recommending your company to anyone who is thinking of installing solar and are looking for a reputable company.
