The smartest energy choice under the sun.

The smartest energy choice under the sun.

ZEN Energy Systems New Zealand has been established by the family behind GB Teat Limited, a successful third generation family business founded in 1947. Having been involved in decades of change within the refrigeration and HVAC industries, they have a strong understanding of evolving markets and new technology. In 2010, following their initial experience with solar energy and energy storage, they realised these would play an increasingly important role in the future of electricity. Driven by this belief they began researching international markets in search of opportunities and partnerships that would enable the introduction of world leading technology to New Zealand. Upon completing this research, ZEN Energy Systems, a successful Australian solar energy company, was identified as their preferred partner. Formed in 2004, ZEN has taken the guesswork out of solar energy and is now a leading renewable energy brand. Integral to this success is a unique approach where all ZEN systems are designed in-house and manufactured to ZEN s specifications under the highest quality and safety standards. This approach combined with ZEN s reputation for quality, innovation and excellence in sustainability earned ZEN s founder, Richard Turner, the Ernst & Young Australian Entrepreneur of the Year award for the cleantech category in 2010. ZEN has been further recognised as a market leader, having been announced Australia s fourth fastest growing company in 2012, up from seventh fastest the previous year. The result of ZEN s continual innovation is its market leading systems which are renowned for their reliability and ease of use. And because each ZEN solar energy system comes complete with the ZEN Energy Manager, it s also very easy to keep track of exactly how much power you re generating. With the same family values and a shared vision for solar energy, the two parties agreed to licence the ZEN Energy Systems brand and product range for the New Zealand market through ZEN Energy Systems New Zealand. Our state-of-the-art range covers all your energy needs, including Solar Energy, Energy Storage and Solar Hot Water. All ZEN systems are installed by our fully trained, professional installation teams and all required documentation is managed by our friendly sales and customer service team. We are delighted to bring our wealth of engineering experience to New Zealand s solar energy market and have made it easy for you to enjoy a future of clean energy with ZEN. With ZEN providing sustainable and self managed solutions, we believe Home Energy will play a large part in the future of energy generation and storage.

This is why the sizing and design of your system are so important. While grid-connected solar energy systems enable the export of excess solar generation to the electricity network, a correctly specified system will maximise the level of solar generation consumed in your home. This creates a better long-term financial return, as displaced grid supplied electricity is usually of greater value than exported electricity. When adopting solar it is important to consider how much electricity you use, at which times during the day and whether there are any seasonal trends. These factors help determine the most suitable system. ZEN prides itself on creating tailored solar energy solutions to suit your lifestyle. So whether you want to offset a portion of your electricity bills or maximise generation for your situation, ZEN can help identify and design the system that is right for you. ZEN s next generation systems also provide the ultimate in flexibility, allowing the addition of further panels at any stage without needing an inverter upgrade ideal for a growing family or if your consumption habits change. To help simplify system selection we have outlined the number of panels, required roof space and average energy production for a range of ZEN Home Energy Systems. To further refine this, simply give us a call and one of our ZEN Technical Representatives can visit your home to assess factors such as local sunlight levels, available roof space, potential shading issues, the amount of energy you should look to generate and the return you can expect from your solar investment. ZEN ENERGY MANAGER Monitor your solar energy from anywhere in the world! Our advanced web-based monitoring solution allows you to see system performance down to the individual panel level on all your web connected devices or PC. Another exclusive benefit with every ZEN Home Energy System.** *The Average Daily Energy production is based on an average of 4.25 hours of peak sunlight per day and solar panels facing north at a ~25 degree incline. These figures were established using NIWA s SolarView tool and on a clear day, energy production can be more than 30% higher than these specifications. **Must have an ADSL2 internet connection as a minimum to use the ZEN Energy Manager web based monitoring.

Heating household water is a major consumer of energy in most homes. Installing a ZEN Home Energy Solar Hot Water System will help the environment and reduce your water heating costs by up to 80%. how Solar Evacuated Tubes work Our Evacuated Tube Systems are more efficient because the advanced, highly streamlined cylindrical tube design incorporates two layers of state-of-the-art borosilicate glass separated by a vacuum layer which acts like a thermos flask, keeping in up to 96% of the thermal energy. So when the small amount of evaporative liquid in each tube is super heated by the sun s energy, it forms a vapour, which rises to the top of each pipe. This heat is transferred to the water flowing through the manifold, and the heated water is then returned to the tank. The result: increased efficiency through maximised heat gain from minimal sunlight. choosing the right tank Where normal quality water supply is available a stainless steel tank is recommended for longevity and efficiency. For areas of poor water quality (for example bore water or hard water with high salt content) vitreous enamel tanks are recommended as they carry a higher resistance to impurities. Warranties Manifolds and tubes include a 10 year warranty. Tanks include a 5 year warranty on the vitreous enamel and a 10 year warranty on the stainless steel. Solar Control Centres and Solar Pumps include a 2 year warranty. solar collector IAM curves* ZEN Evacuated Tubes Standard Evacuated Tubes Flat Plate Sunrise Midday Sunset Cross Section of Evacuated Tubes ZEN s next generation evacuated tube technology delivers significantly better performance than traditional flat panel absorbers, maximising heat gain from minimal sunlight. With 80% more efficiency than standard electric water heaters, a small amount of hot water boosting can still be required.

Our electric booster ensures the water temperature is maintained at 60 C, while gas boosting only occurs when the water is on and the solar tank is not up to temperature, with ZEN s highly efficient gas booster ensuring you have plenty of hot water year round. iam factor 1.60 1.40 1.20 1.00 0.80 0.60 0.40 0.20 0.00 90º 80º 70º 65º 60º 55º 50º 40º 30º 20º 10º 0º 10º 20º 30º 40º 50º 55º 60º 65º 70º 80º 90º Sunrise Midday Sunset * IAM (Incidence Angle Modifier) Degrees from Centre

Taking energy security for your home to the next level Having developed our fully branded and integrated ZEN solar energy range, ZEN Energy Systems has now created a worldleading energy storage system, the ZEN Freedom PowerBank. This revolutionary system is changing the way the world uses power - offering you the kind of energy independence you ve always wanted. Loads of great benefits In the past, people have been unable to efficiently and effectively store the power generated through their solar energy systems or make the most of off-peak power prices. From now on you can expect constant electricity supply, regardless of blackouts or temporary outages and use it whenever it s most needed at the cheapest possible rate.* *Check if off-peak time-of-use tariffs are available in your area. Putting you in control The ZEN BOS (Battery Operating System) is now into its 3rd generation of use, and has the capacity to harness maximum performance from low cost Lithium Ion batteries, creating the highest and most efficient level of functionality for the home or business user. The launch model of the ZEN Freedom PowerBank has been designed to satisfy the requirements of the average New Zealand home 20kWh for both on and off grid. The new 10kWh ZEN Freedom PowerBank has now been added to the range. want to know more? To learn more about the ZEN Freedom PowerBank s full functionality and suitability, give us a call today.
