Our Values


Reliability & Integrity

Trust is vital in business, especially when time is of the essence and a successful outcome is needed first time.
That’s why we go out of our way to create open communication channels between all parties, project managers, surveyors, designers, engineers. An open dialogue and collaborative approach leads to success.

High Standards

We set ourselves big goals in terms of designing and engineering sustainable solar projects.
Our aim is to help create a cleaner environment. Not only that, but we want to do it as efficiently, accurately and quickly as possible.
We strive for absolute precision, as we know design inaccuracies lead to installation problems. We have robust systems in place to maintain the highest standards in the industry.

Sustainability

We aim to continually minimise our impact on the environment.
By nature of what we do, we’re helping to reduce carbon emissions into the atmosphere, benefitting society as a whole.
Also, we’re always looking for ways to reduce our own carbon footprint with green initiatives within the business.

Respect

We have a culture of respect at DETRA. We have absolute respect for our clients, colleagues and any other parties we work alongside.
Our entire business is based on respect for the environment. As solar engineers, we are pioneers of a more ecologically sound and sustainable source of energy.
We are also mindful of keeping local environments attractive, and we factor this into our designs.
