ZEN Energy Systems is very proud to have completed the installation of a 42 kW commercial solar energy system for Whangaparaoa College in Auckland, adding to ZEN's growing list of commercial solar installations.
Whangaparaoa College is a state secondary school located on the Northshore of Auckland, delivering positive learning outcomes to approximately 1,500 students. With the school being committed to energy efficiency and sustainability, it was driven to demonstrate this to staff, students and the general public. Through third party consultancy, TorqueIP, the school issued an Request for Proposal to identify a specialist solar energy partner with the necessary experience in the design, planning, scheduling, permitting, installation, testing and commissioning of commercial solar energy systems, to ensure a fully managed and well executed commercial solar energy project.
With a large baseload energy demand and heavy daytime use, Whangaparaoa College was looking for a commercial solar energy system that would:
Upon being awarded the contract to complete the project, ZEN set about delivering a commercial solar energy system that the school would be proud of, both today and well beyond the expiration of the 25 year dual warranty period.
Making full use of the school's 'J Block' roof and enabling visibility to students and visitors, ZEN designed the commercial solar energy system to consist of 150 x 280 watt LONGi Solar panels on tilt frames, to maximise year round generation. Each panel has been paired up with an AP Systems micro-inverter, delivering on the school's desire for long-life warranties of 25 years (matching panel performance warranties) and individual panel monitoring.
In the same manner as a commercial business, the school's operations are ideally matched to benefit from solar energy. The extensive consumption analysis completed by ZEN showed that even at the height of summer, during the school holidays, the school baseload demand will be significant enough to see close to 100% of the solar generation used internally. Continued monitoring of system generation vs. comsumption will further help understand the needs of any future system expansion.
With an expected output of approximately 59,000 kWh per year, the system will provide approximately 12% of the school's current electrical demand. To put this into persepctive, this is enough energy to run seven standard New Zealand houses, 24 hours per day, 365 days of the year. Not bad for a single commercial roof!
Commercial Solar Energy is especially important for schools. As Sustainable Electricity Association of New Zealand chairman Brendan Winitana has discussed before, the country's 2,500 schools could cut their power bills by $20 million a year if they all installed solar energy.
"Schools are the perfect place to install solar because they consume all of their energy during the day and can, therefore, maximise the financial benefits," he said.
"If every school in New Zealand were to install a 25 kWp [kilowatt peak] system then the cost would be about $150 million and this is the scale that the Government should be investigating because it makes financial sense.
"A solar system installed on a school in New Zealand would be paid back within seven years, after which time the savings made on the electricity bill could be diverted into better learning opportunities for students.”

ZEN Energy is proud to be part of this movement by installing high quality commercial solar energy systems for our future generations.
Importantly, for both ZEN and Whangaparaoa College, the visibility of the system and its performance will help to educate the students and allow them to grow throughout their secondary education with an advanced understanding of the real world benefits of solar energy. We believe this education and understanding will help form a generation of New Zealanders where solar energy becomes second nature and just a standard part of everyday life. Where commercial solar energy systems will be seen on the majority of available rooftops, delivering local and abundant energy to all types of enterprise.
This is what we at ZEN are striving to achieve.
"It’s been great. We have noticed savings from the very start, the wine was nice I won’t lie. Our bills are 40-50% less."
"I was skeptical about the savings at first, we are now saving over 50% on our power bills, summer ones have dropped from $450 to $200 and winter has gone from $660 down to $320. We are happy with how persistent Jake was, the results are great"
“Pretty good I am a country bumkin so pretty good is pretty good, our winter bills have dropped from $400 – $260 & summer from $130 down to $60. I have been recommending ZEN to anyone who asks”
