solarZero® explained

solarcity is a solar energy services company focused on delivering cheaper, smarter, clean power to all New Zealanders. Our commitment and vision guides us when sourcing the very best products from local and international manufacturers. 

our solar panels
Photovoltaic panels

Solar photovoltaic (PV) panels are transforming the global solar industry as they can generate cleaner, and often cheaper, electricity compared to fossil fuels.

General benefits of our solar panels: 

  • Provide clean, green energy.

  • Have a 1 to 2-year energy payback cycle by which time the solar panels will have produced the equivalent amount of energy used in their manufacture. Over their 20-year lifetime they will pay back their energy debt by more than 10 times. We purchase carbon credits to offset the emissions associated with the transportation of our panels.

  • Made predominantly from silicon dioxide silicon (sand). They do not contain toxic materials like mercury, lead or cadmium.  

  • Generate electricity from sunlight through the photoelectric effect, producing direct current electricity.

  • Operating and maintenance costs of panels are considered low, relative to the costs of other renewable systems.

  • No mechanical moving parts. Consequently, they have significantly fewer breakages and require less maintenance than other renewable energy systems.

  • Totally silent making them ideal for urban areas.

  • As solar energy is produced during the day it is perfectly suited to power air-conditioning units and swimming pools - heavy energy users during the summer months. In fact, the benefits of solar extend to all household energy needs like washing machines, vacuum cleaners and home entertainment systems.

Canadian solar panels

  • Canadian solar is a world-leading manufacturer of high-performance photovoltaic products. 

  • Founded in 2001. 

  • One of the world's largest producers of solar cells and modules.

  • Its standard and high-efficiency product offerings are among the most powerful and cost-effective in the industry.

  • The CS3K 295 solar panel is a poly crystalline module designed for residential, commercial and utility applications with an efficiency of 17.75%.

  • Anti-reflective and anti-soiling surface reduces power loss from dirt and dust.

  • Outstanding performance in low-light irradiance environments.

  • Excellent mechanical load resistance: certified to withstand high wind loads and snow loads.

Micro Inverters

Inverters convert the direct current (DC) electricity generated by the panels into the alternating current (AC) electricity. 

Roof framing system

We install on the following roof types: corrugated iron/steel roofs, metal profile roofs, concrete tiles and decramastic tiles.. The solar panels are fixed to the roof using aluminium racking that is specifically designed for the solar industry. solarcity uses Clenergy framing systems because of these features:

  • Versatile - can be installed on many different roof types.

  • Strict quality control in accordance with ISO 9001 ensure optimum strength and long life.  

  • Structural engineering certificate proof of suitability with wind, snow and seismic loads experienced in New Zealand.

  • 10-year warranty on all components.

Delivering your grid power 

Your home stays connected to the grid which supplies your power when the sun's not shining. You buy that power at a special rate that's cheaper than you can get from any of the traditional power companies and we pass it through without adding any mark up. We call that mates rates. 

Panasonic battery 

Solar batteries optimise the way power is stored and used in the home. They store surplus solar power generated during the daytime so it can be used at night. We have an exclusive deal with Panasonic which has been ranked the leading lithium-ion battery industry and innovation for the past 40 years. It was also ranked No. 1 in the Electronics Sector for the "Best Global Green Brands 2014" by US consulting company Interbrand. 

Key benefits of Panasonic's solar battery: 

  • Standalone lithium-ion battery delivers a turnkey solution, fully integrated with inverter, all manufactured by a single brand. 

  • 5.3kWh usable capacity and 2kW input and output power. 

  • Maximise self-consumption mode or programme charge and discharge times. 

  • Can store grid power when the rates are lower to use during peak times. 

  • Backup mode can power a few critical devices when the grid goes down. 

  • Steel chassis will last outdoors and is installed on floor, or concrete pad, for safety. 

  • 10-year manufacturer's warranty and a 10-year performance warranty based on one full charge and discharge cycle per day. 

  • Only requires a maintenance visit after 10 years to check performance and any general wear and tear.

solarZero® monitoring app 

We install our state-of-the art online monitoring and control platform at the same time as we install the solar panels. Accessed via your smartphone, tablet or computer it can help transform your home into a smarter home: 

  • Monitor the solar system's generation - including surplus solar power exported to the grid. 

  • Track your home's energy use. 

  • We pre-wire your hot water cylinder so you will be able to control it remotely in the future.
