Reviews from long standing customers

“After buying our first solar panels in 2014 the ECU died. The service and dedication is second to none! They had to source a new one from Aussie and Mark from the technical department was with me all the way to install and get it working . Awesome. Also Rotorua local Susan was fast in response as was Auckland with updates every couple of days.”

JEAN-PIERRE PAALVAST

“We’ve had our solar system for four or five years and it has generally been running well. When an issue recently came up, the team was patient, professional and thorough, and resolved it quickly. We really appreciated their care and excellent service. Highly recommended.”

CRYSTAL CHEN

“I have been a Zen customer since around 2014. I updated my system a couple of years ago to include a battery and larger solar array. Zen have been professional to deal with at all times, delivered a very tidy quality solution and have provided timely support whenever I have had a technical query.”

MATTHEW BAMBURY

I can honestly say ZEN Energy has been outstanding.  Years ago, I invested in a very early-adopter energy system coming out of Australia. What impressed me most was ZEN’s willingness to step in, properly diagnose the problems, and ultimately rebuild the system into something reliable and future-proof.  Fantastic people. Fantastic service. Five stars from me.

Solar panels are installed on your roof and produce electricity in DC current. This electricity is converted to AC current through your solar inverter and then delivered via your house’s switchboard, to your appliances, such as your television, hot water cylinder, fridge and heat pump. Any excess electricity generated will be sent back to the grid, for which you will get a credit on your electricity bill if your electricity retailer has a buyback offer.

The length of installation depends on the size of the solar power system, whether it includes batteries and the roof condition, but will typically take anywhere between 1 day for a grid-tied installation and 2 days for a more advanced battery based system.

They are effective during the winter months; however you will notice a considerable drop on the overall solar generated compared to the summer months. This is normal due to the height of the sun in the sky and there being less sunlight hours over the winter months.

If your roof is in good condition, and gets a lot of sun, it is probably a good candidate for solar. We do not recommend installing solar on old roofs. The panels are expected to last for over 25 years so it is not recommended to install them on a roof that may need replacing during the life of the system.

Solar power is the most abundant renewable energy resource on Earth. Solar power systems do not emit any CO2 and their costs have been consistently reducing. In contrast, fossil fuels are being depleted, with unpredictable prices that are typically trending upwards. Additionally, they are not renewable. Solar power is the clear answer for the future of energy as it localises energy generation at the point of consumption and passes the power to choose back to the individual home owner. Although many large entities are not yet committed to solar power, a household can proactively choose to benefit from having a solar power system on its roof.

Most power companies currently pay at 8c/kWh for electricity exported to the grid. You will need to contact your power company to confirm their buyback rate.

Whilst there are costs to you in purchasing and owning the solar system, solar power will help you to reduce your monthly electricity spend by offsetting the energy usage in your house. How much your monthly electricity bill will reduce by will depend on a number of factors, including the size of the system that you install, how much electricity your system generates, and how much electricity you use during the day.

The size of the system is often determined by the available roof space of the property and size of the system you require. As a guide, most panels are 992mm wide by 1640mm high in size. Approximately 8 m2 of roof space is required per 1 kW of solar panels.

Solar photovoltaic panels require little maintenance. Your panels can build up dust and other material over time. Solar panel cleaning is not that different from cleaning your windshield. This can be done with water and a soft brush.

Yes the solar panels will still produce power however the solar inverter requires you to be connected to the grid for the inverter to operate and provide power to your home. This is a safety mechanism to protect appliances at your property for the safety of network maintenance personnel.

Solar panels that face north get the maximum amount of sunlight during daylight hours to generate electricity. Placing panels on the east or west-facing roof will still produce a substantial amount of power. It is not recommended that you install panels with a southerly aspect.

Three phase properties may require a 3-phase solar system. With a three phase solar system there may be instances when you will import energy on one phase while exporting energy on another phase. This is because all three phases operate independently of one another. You may want to ask your installer to check the loading on each phase as part of the installation process.
