100kW Commercial Solar Case Study

Dentro Joinery was established in 2007 and is a specialist industry leader delivering joinery services to commercial clients. The business operates from new facilities in Prestons NSW with all new machinery.

With power bills of over $30,000 per year, Dentro asked SolarBright to propose a suitable commercial solar solution.

Installing a commercial solar system for your business is a straight forward decision. As with all business investment decisions it is all about the Return On Investment (ROI). When proposing a commercial solar system for a business, SolarBright examines the current power usage patterns, and design a system that suits their requirements.

Using an advanced satellite-based solar mapping software, SolarBright maps the solar panels onto the roof. The software takes into account the location, panel model, panel tilt and orientation to produce a report that gives the estimated output of the system allowing us to calculate estimated yearly savings and payback time.

Customer Reviews

  • Just wanted to say a huge thank you to you and your team. My skylight is installed and it is SENSATIONAL!!!!!!! Can't believe I have been living without it for all these months...

    LorenHome Owner, Mt Annan

  • Tricky Skylight Install! Great service, especially the installer Sam. We had a tricky install for the skylight with an old house and ornate ceilings. That didn’t stop them. I spoke to the team at the store to clarify details then when he came out he was able to get it installed in under 2 hours - perfect. Thank you.

  • Great Service and great people to deal with. From the start, all the team at Solar Bright respected what I asked for. They politely gave me their quote and patiently answered all my questions without harassing me with never ending phone calls… We had a 5KW solar system and Powerwall 2 installed on the day they said, and all the installers were great to deal with and did a fantastic job. My wife and I have no hesitation in recommending SolarBright for all your solar needs.
