New Mitsubishi Solar Installation at Wellington Zoo

Tuesday 23rd of February 2016
Since becoming the world’s first carboNZero certified zoo in May 2013, Wellington Zoo has strived to continue reducing carbon emissions. After identifying electricity usage as the single largest contributor to their carbon emissions profile, the zoo has taken a further step towards their goal.

This month Wellington Zoo, in collaboration with the Sustainability Trust, installed 48 Mitsubishi Electric Monocrystalline Photovoltaic solar panels. This installation is set to reduce Wellington Zoo’s carbon emissions substantially, while saving them the same amount of power used by one and a half average New Zealand households each year.

Benefits of choosing Mitsubishi Electric Solar PV

Friday 23rd of October 2015
Amidst a sharp increase in recent media exposure the solar photovoltaic industry has experienced unprecedented growth in New Zealand. The result of this has been increased awareness of the benefits of solar PV, and Mitsubishi Electric has been approached by many Kiwis researching solar PV applications for their own homes.

There are many benefits of choosing Mitsubishi Electric Solar PV, but one of the most paramount is the confidence in choosing a tried and trusted brand over overseas supplier’s with no proven track record. Mitsubishi Electrichas been offering reliable products since 1921, and has been in New Zealand since 1981, meaning customers can be confident their Mitsubishi Electric solar PV panels will perform throughout the 25 year warranty period.. Additionally Mitsubishi Electric’s locally based technical support team consistently provide superior support, for which solar PV is no exception.

It is well known that solar PV systems achieve peak generation at times where solar irradiance levels are at their peak - during the middle of the day. For the average consumer this means peak generation and peak demand are not aligned, with most households experiencing demand peaks at either end of the day. Household habits need to be changed to increase the self-consumption of units of electricity at time of generation. This ensures the homeowner is maximising the value of each unit of electricity generated, and as such increasing the ROI. Understanding the importance of self-consumption on ROI, Mitsubishi Electric’s nationwide base of solar PV specialists are capable of tailoring a system to meet individual needs.

A lot of discussion currently focuses on the buy-back rate offered for excess electricity exported to the grid. However, this should merely be an afterthought, or a bonus of having Mitsubishi Electric solar PV installed on your home. For instance, the value of one unit of electricity generated by solar PV can be either:

  • The rate at which the consumer pays for one unit from the retailer or
  • The value at which each unit is credited when exported to the grid.

As a majority of buy-back rates are currently of lower value than the average retail rate for a unit of electricity, self-consumption presents a favourable advantage. Adding to this, if a unit is self-consumed the consumer does not have to purchase this unit from their energy retailer at full retail price.

Coastal environments are of course common in New Zealand, so Mitsubishi Electric Solar PV panels are designed with a double anti-corrosion coating, meaning the panels can be safely installed in areas with high salt concentration in the air. The panels are also developed with lead-free solder to protect our environment.

Which system is right for you?

Thursday 3rd of September 2015
As consumers, home owners in the 21st century are constantly on the lookout for new ways to future proof their home. Whether a new building, renovation of an existing dwelling or simply when considering home improvements, future proofing is an important step to consider.

Many home owners are already choosing fittings and appliances which improve energy efficiency and help to reduce their overall energy consumption. However as society gravitates towards cleaner, renewable sources of energy, consumers now have the option of taking the concept of energy efficiency further. Installing solar PV will not only further reduce energy spend; it can potentially eliminate it all together.

Solar power is clean, renewable and abundant. The amount of sunlight striking earth in any given hour contains enough light energy to meet the entire world’s total energy consumption for one year – making solar PV one of the most indispensable sources of clean energy and once harnessed, can provide huge energy saving benefits.

Which system is right for your home?

Mitsubishi Electric has recently launched an online solar calculator to assist homeowners in calculating the benefits of renewable energy at the touch of a button. As a tool, the online solar calculator can provide home owners an idea of the ideal solar PV system for their home. Estimates are made based on four key criteria; the household’s monthly power bill (kW usage), cost per kW unit (incl GST), what roof type the home has, and the region the house is located in.

Not only this, the online solar calculator estimates annual energy generation and provides estimated annual savings, giving the homeowner peace of mind when it comes to rising power bills. Additionally, Mitsubishi Electric takes the hassle out of the process by breaking down the componentry of the suggested system and as well as directing consumers to a specialised installer in their area.

Solar generation doubles in 2014, renewables reach 17-year high

Wednesday 19th of August 2015
The release of the Ministry of Business, Innovation and Employment, 2015 Energy in New Zealand Reports show that the total energy generated from solar PV doubled in 2014.
In December 2014 total generation from grid-connected solar stood at 18.8 MW, and SEANZ can confirm that the six months of 2015 growth has continued at an even greater rate.
The increase in solar generation comes as the country’s total renewable electricity generation grew to almost 80 per cent, up from 75 per cent in 2013, and the highest since 1996. Primary energy supply from renewable sources hit a record of almost 40 per cent.
