Hands-on solar installation training

A new two-day course designed for electricians who want to master the skills needed to design and install domestic solar photovoltaic (PV) systems is now available from Trade Master.

The course is being introduced at Trade Master’s training centre in Penrose, Auckland where electricians and electrical inspectors looking to add installing or inspecting PV installations to their existing skills and business offer can successfully expand their expertise into solar and renewable energy.

Trade Master’s head of training, Andreas Kasoulides, says the course provides a path to competence in PV installations, and to ensure course attendees get the most out of the course, Trade master has developed an e-learning component.

“We give attendees some pre-reading to do as soon as they register. This self-directed work is available on our learning management system and sets them up for more effective face-to-face training with our tutors.

“The course is really a four-day course, but you only have to be away from work for two-days because we have designed the self-paced online learning module to be studied before attending the course and consolidated after the two-days intensive training. The module will remain available to attendees thereafter.”

The first training day at the training centre is theory based, covering design and all the processes to install and test an installation, says Kasoulides.

“The second day we put it all into action with practical training in how to put a system together. This includes gaining hands-on experience in mounting systems and solar panel installation on actual panels set up in the training centre.

Subcontractors win control of retentions

When a construction company goes belly-up and receivers and liquidators step in to recover whatever funds they can and distribute them to creditors, retentions withheld from subcontractors become part of that recovery. The trouble starts when liquidators deduct their fees from that pool of money and seek to include retentions in that pool.

That is less likely to happen in future thanks to a High Court decision by associate judge Brittain in a case brought by a liquidation committee of subcontractors seeking to overturn the decisions of the liquidators of Stanley Construction Ltd and Stanley Construction (Auckland) Ltd.

The following article is drawn from the judge’s findings on the matters put to the Court where subcontractors asked the judge to determine just who was the beneficial owner of the retentions and funds gained as part of the retention recovery. The subcontractors’ committee also asked the Court to review the remuneration the liquidators’ paid to themselves using the recovered funds.

The case produced a win for the subcontractors when on 29 August 2025, judge Brittain reversed the decisions of the liquidators of the construction companies who had applied the funds they recovered in relation to retentions to their own remuneration and expenses in carrying out the liquidations.

The judge reserved leave to the parties to seek further direction from the Court to determine how the settlement payments and the recovered retentions, (less any remuneration and expenses allowed to the liquidators), should be distributed amongst the subcontractors; and how the retentions proceedings will be conducted in the future.

While that should be resolved in a hearing on 29 October 2025, the judge has already ruled on just whose funds the recovered retention-related funds are.

Reforming electrical training in New Zealand?

How electrical training will be designed for the future is now at a turning point. Tony Jaques, head of Integrated Systems Design Ltd, an industrial electrical contracting business specialising in automation and robotics, says we need a new vocational training model that begins in schools. For 15 years Tony Jaques was a moderator with Skills in the development of unit standards for electrical qualifications and is currently a moderator with Wintec and on its Apprentice Training Advisory Board. He comments as follows.

The electrical industry in New Zealand is experiencing rapid technological advancements and an increased demand for skilled professionals. To meet these demands, it is essential to reform electrical training programmes and ensure that they are up-to-date and comprehensive. This article explores the current state of electrical training in New Zealand, identifies the challenges faced, and proposes innovative approaches to reform and enhance the training programmes.

Electrical training in New Zealand is primarily conducted through apprenticeships and technical courses offered by polytechnics and private training providers. These programmes typically combine theoretical instruction with hands-on practical experience, allowing trainees to develop a well-rounded skill set. However, there are several areas where improvements can be made to better align training with industry needs and technological advancements.

Lighting as visual cues

Lighting can perform a multitude of operations, from simple illumination, through to providing task lighting or creating atmospherics for performance art, the list is endless. However, one of its more subtle abilities is to provide visual cues, which are often achieved by more subliminal measures, using innate tricks of human natures response to light, or cultural norms.

Human nature revolves around our relationship with light, and our total dependence on it. Light has always meant life, whether through its direct effects via the sun and its life nurturing warmth, or its secondary device of illumination, through which we have evolved to adapt our ability to navigate our environment around us.

The importance of light to our brain is immutable from our human experience. Even for blind individuals, most are still able to sense light, or at least the non-visual eye receptors still operate to allow for circadian lighting entrainment. It is no wonder then that as we have technologically created alternative light sources, we have looked to use lighting to our own advantage and spent so much energy refining our knowledge around the tricks of the lighting toolkit.

The first and most important rule that we can intuitively understand is that of the fact that the human eye is naturally drawn to the brightest light source. This is used time and again and the classic portrayal of this is within the theatre setting.

One of the first applications of intentional lighting cues was the use of limelight in theatrical performances, where in the late nineteenth century quicklime was heated to create an intense light that could be funnelled via mirrors and tubes as a spotlight. This new technology replaced candlelight as an ambient source and though it was relatively quickly replaced with electrical light sources, the phrase, to be in the limelight remains. This use of a spotlight in the theatre setting is the most obvious example of how the bright light draws the eye, and therefore the attention, but it has been refined and used in all aspects of our lives.

Lighting, the path to sustainability

Undeniably, the transition to LED lighting has been a force for good for environmental impact. The savings in energy usage alone makes LED a force for positive change, add that the replacement of outdated technology like fluorescents and high intensity discharge lamps removed many heavy metals and toxic elements from the industries' contribution to hazardous waste, and the ongoing success of the transition to LED has had a net positive result. The journey to environmental sustainability however is far from over, and the age-old conflict between profit, economics and environmental principles continues.

There is still so much potential within the lighting industry to play its part in taking steps to be a good environmental partner, small choices that are made every day, or engineering revolutions that can herald technological breakthroughs. Fortunately, many smaller, more agile companies are looking to be more than just a follow the crowd producer, and even the lighting industry heavyweights are prepared to make sincere efforts for positive change and innovation.

Within the industry, every lighting company representative comes armed with news of their efforts to become more sustainable and their role in the onwards march to greener solutions. Some of these companies truly follow through on their promises, others deserve a sideways glance as they then extoll the low cost of their products to market. The investigations into the widely recognised fast fashion industry have opened the eyes of consumers to see the true impact of selecting low-cost options not at their wallet, but on that of the greater environmental picture.

Any broadening of this awareness of the impact of low cost, high turnover products to other industries is a timely happenstance and one the lighting industry needs to embrace. Within the low-cost luminaire market, the cost of installation regularly outweighs the cost of the product.

Whenever this scenario plays out, it’s a simple equation that proves that any impactful return on investment for the client is going to be an unlikely scenario. Any maintenance or early replacement on low quality luminaires will probably outweigh any benefits on the savings from using a low-cost solution.

When luminaires have a potential of 10 plus years of life in a commercial installation, using a product that it is only rated for three is nothing but short sighted. It is not only the final financial costs, but also that throughout the entire product supply chain that needs to be calculated, from the cost to the environment throughout the manufacturing process, the infrastructural costs of freight and packaging, through to the disposal of the end-of-life product.
