Q&A

Why Should I Switch to Solar Energy?

Electricity prices in New Zealand continue to rise (an average increase of 3% per year, with a total increase of over 60% since 2006). The risk of power outages is growing (due to natural disasters and an aging grid, large-scale power outages are becoming more frequent across New Zealand). The cost of purchasing solar energy has decreased (thanks to our efforts). These three factors combined make solar energy a wise investment choice.

There is also an important but often overlooked factor: statistics show that homes with sustainable energy sources like solar energy tend to have a 3-6% higher market value compared to similar homes.

What Does a Solar Energy System Include?

A complete solar energy system includes solar panels, an inverter, batteries (optional), mounting brackets, wiring, a smart meter, and solar monitoring software/app.

How Many Kilowatts of Solar Energy Should I Choose?

First, consider your needs: your monthly electricity bill is the best reference to gauge your household’s energy consumption. Generally, if your monthly electricity bill is under $300, a 5-6 kW system should be sufficient. For bills between $300 and $400, a 10 kW system is appropriate, and for bills over $400, a 15 kW system or larger may be needed.

Next, consider your roof size: the larger the roof, the more solar panels you can install, and the greater the power capacity.

Why Are Solar Batteries So Expensive?

Yes, solar batteries are the most expensive component of the entire system, and inverters compatible with batteries are also more costly than standard inverters. Therefore, we recommend users clearly assess their needs. If you can concentrate your electricity use during the day, you may not need a battery, which would significantly reduce initial installation costs.

However, batteries do have their unique advantages.

First, if your home is mostly unoccupied during the day and electricity usage peaks around 4-5 PM, a battery is necessary to store daytime energy for use in the evening. Additionally, a battery can store electricity from the grid during off-peak hours when rates are lower and use it during peak times. This is the only way to effectively take advantage of low-cost electricity.

More importantly, the biggest advantage of a battery is energy security. A 5 kW battery can provide power for several hours to a full day during an outage. In fact, during a short outage, you might not even notice it and can continue life as usual. Larger batteries also make partial off-grid living possible.

Can I Start with a Basic System and Add a Battery Later?

Yes, you can. However, note that inverters compatible with batteries differ from standard inverters. So, if you plan to add a battery later, choose a hybrid inverter when purchasing the basic package. It costs about $2,000 more than a standard one but ensures a smooth battery installation later. If you choose a standard inverter, you’ll need to replace both the inverter and add the battery later on.

What Maintenance Does a Solar Panel Require?

Solar panel maintenance is very simple and minimal, and you can usually do it yourself. They are built to withstand weather conditions, and generally, occasional cleaning and inspections are enough to ensure normal operation and prevent damage.

How Do I Clean Solar Panels?

Due to the glass cover, solar panels typically require little maintenance, as the cover itself helps keep them clean. Occasionally, if dirt like leaves or debris accumulates, gently cleaning with water from a hose, a sponge, or a soft brush is enough. Regular observation is key to spotting any buildup that could affect efficiency. Generally, the protective coating on the panels helps rain and sunlight keep them clean, minimizing the need for frequent cleaning.

The Initial Investment Is Too Large; Can I Get a Loan?

Of course. Banks like ANZ, ASB, and BNZ offer 3-year loans at a 1% annual interest rate, where you only pay 1% interest during the first three years. Starting in the fourth year, the loan amount will be added to your mortgage and repaid along with it.

Additionally, Q-card offers 24 months of interest-free loans.

Are There Subsidies for Installing Solar in New Zealand?

Unfortunately, New Zealand does not offer any official subsidies. This is why we organize group purchases. Group purchase prices are over 10% lower than market prices, helping you shorten the investment payback period by 1-2 years.

Why Are Your Prices Lower? Is the Quality Guaranteed?

The price of a solar system installation includes three components: solar equipment procurement costs, installation costs, and the company's profit. Installation costs cannot be reduced because solar equipment installation requires qualified workers, and labor in New Zealand is expensive. Over time, these costs will only rise gradually. Therefore, the discount from group purchases mainly comes from the bulk procurement cost of solar equipment and the company passing savings on to customers.

Through this method, you can get a high-quality solar system at a better price.

Do You Only Offer These Brands in the Group Purchase Packages?

No, we will offer group purchase packages from different brands. However, each package is carefully selected by our experts to ensure high-quality products with the best value for money.

Can the Group Purchase Price Be Discounted Further?

Yes. You can refer others to join the group purchase package. For each successful referral, you will receive at least $300 and up to 5% of the referral bonus.

How Many Solar Panels Does My House Need?

This depends on your roof area. A solar panel covers about 2 square meters (1 meter by 2 meters). If your roof is wider than 2 meters and longer than 12 meters, you can install at least a 5 kW system.

How Much Will Installing This System Save on Electricity Each Year? Is It Worth It?

Generally, a 5 kW system generates about 6,000-7,000 kWh per year. If your electricity price is $0.23/kWh, you’ll save $1,380-$1,610 per year. If the price is $0.25/kWh, you’ll save $1,500-$1,750 annually. A tip is that once you install solar, you can switch to a low fixed rate, high electricity price plan to save more.

My Monthly Energy Bill Is Around $300, But More Than Half Is Gas. Is It Worth Installing Solar?

In this case, we suggest gradually converting all energy sources to electricity. Gas costs will continue to rise. As shown in the diagram, fully electric homes are the future trend.

Can Solar Panels Generate Electricity on Cloudy Days?

Yes, unless it’s heavily overcast, regular cloudy days will still allow for electricity generation, though at a lower efficiency compared to sunny days.

It Seems Complicated, and I Don’t Know How to Proceed.

The purchasing process is simple:

1. Pay a 10% group purchase deposit — 2. Installer comes to measure your roof — 3. Sign the installation contract and pay 50% of the contract amount — 4. Installation — 5. Third-party inspection — 6. Pay the remaining 40%.

In this process, you only need to handle the payments in steps 1, 3, and 6; our staff will take care of the rest.

Usage Instructions:

Once installed, you’ll receive a complete solar system, from the rooftop panels to the inverter and optional battery mounted on the wall. You’ll also download the inverter manufacturer's control app. Our staff will teach you how to monitor your electricity usage and manage your power distribution. The operation is very simple.

In the first month after installation, you’ll enjoy a significant drop in your electricity bill. If you’ve opted for a battery, you’ll be well-prepared for power outages. In case of a short outage, you might not even notice it.
