Commercial and Industrial Solar Energy

Commercial and Industrial Solar Energy Solutions


Want to reduce your energy costs?

 Were you aware that you can reduce the upfront cost of a solar installation by as much as 40% with the federal government's STC rebate?

Commercial and industrial clients across Australia can capitalize on this opportunity to minimise installation expenses. Here's how:

Decrease in Electricity Expenses: Industries and commercial establishments in Australia are burdened with high energy bills. Solar power systems provide a solution by generating electricity onsite, thereby reducing dependence on the grid and cutting down costs.

Long-Term Investment: Although the initial outlay for solar infrastructure may appear substantial, it yields significant returns over time through reduced operational expenses and insulation against future increases in electricity rates.

Government Incentives: Various government incentives, including Small-scale Technology Certificates (STCs) and tax advantages, enhance the financial appeal of solar installations for businesses, making them even more attractive.

When you consider that this program is paired with other solar energy generation benefits such as decreased electricity bills, improved energy efficiency, as well as the incentives offered by feed-in tariffs, you can see why a renewable energy investment is a smart choice.



Only authorised retailers like Greentech Engineering Solutions participate in the program. That’s because GES has extensive experience in building and designing integrated solar power systems. Our installers are also fully accredited by the CEC of Australia.

Our SAA-certified installer is proficient in:


Designing systems for projects ranging from 10 kW to 5 MW.

Facilitating grid connection applications and commissioning the systems.

Providing a 10-year warranty for all commercial and industrial projects.

Assisting system owners in system health checks at minimal costs.

Monitor all installations and regularly update customers.

How Does Solar Power Work for Commercial Properties?


Your business can’t afford to be without power, which is why we educate you on how your solar PV system works and why you’ll never be without electricity.


Unlike residential consumers who get billed for the kWh consumption, business customers are required to pay demand charges on a kW basis.

These demand charges can make up a significant part of the energy bill and are generally calculated by reviewing the greatest amount of power you need during demand spikes in a billing cycle.

An expertly designed solar system with battery storage can help reduce demand charges by discharging energy at peak times and allow you to reduce the amount you owe on your energy bill.

Industrial Solar Energy Solutions

Grid Application

Our team can reduce the complexity of grid applications and make the process easy for distributors. We meet the distributors’ requirements to eliminate the risk of delaying the project or being refused altogether.

Grid Connection

A suitable grid connection can be acquired to evaluate and comply with regulatory requirements. It is important to understand the cost and feasibility of your new renewable energy project, as well as the grid capacity to accommodate new generation. Our team will help you investigate the feasibility of connecting to a network, as well as the potential impacts of connecting a particular network. The process of evaluating network connection feasibility can also include an estimate of the likely costs of grid connection.

Injection Testing and Commissioning


We offer comprehensive testing and commissioning services to commercial and industrial solar installers. Secondary protection relays of any type can be tested as per DNSP, distribution network service provider requirements.

Secondary Injection Testing

Injection testing is mandatory for most electrical distribution networks and is essential to getting your system commissioned. We use CMC 356 for secondary injection testing.

Power Quality Testing

Power quality testing, or PQ testing, is required for most commercial installations and helps to assure distribution companies that your solar system is not contributing to voltage problems. Our team utilises Fluke 435 for power quality testing to streamline the complex process of testing so that you can connect your system to the grid fast.

HV Solutions


We design high-voltage (HV) PV solutions for utility-scale consumers, microgrids, and solar farms. One of the main reasons as to why power is transmitted at high voltages is to improve the efficiency of the system.

We design custom-built solutions for the following:

  • Microgrids
  • Utility-scale Solar Facilities
  • Solar Farms
  • Own Engineering
  • ...and more.

We serve all of Australia and have accredited commercial solar installers in the following states:

  • Victoria
  • New South Wales
  • Queensland
  • Tasmania
  • Western Australia
  • South Australia
  • Canberra
