The Piet Retief Sawmill grid-tied solar system with generator integration is a pioneering project that epitomises the synergy between renewable energy and industrial operations.

It demonstrates how solar power can be effectively harnessed to achieve energy independence, cost savings, and environmental benefits. This project serves as a model for other industrial facilities looking to transition to sustainable energy solutions and reduce their operational costs.

The Piet Retief Sawmill project showcases an advanced 300kW grid-tied solar system with seamless generator integration, reflecting a significant leap towards sustainable and cost-effective energy solutions. This installation not only highlights the commitment to environmental stewardship but also demonstrates substantial financial savings and operational efficiency.

The system generates more than 500MWh of electricity annually. This remarkable output not only covers the sawmill’s energy requirements but also contributes to the local grid, promoting renewable energy adoption in the community.

The environmental benefits of this project are substantial. By significantly reducing the need for generator fuel, the sawmill has decreased its carbon footprint. The project has an equivalent environmental impact of:

  • Saving 11,850,147 litres of water, typically required for traditional energy production.
  • Providing an EV range equivalent to 2,428,806 km, showcasing the potential for clean energy to power electric vehicles and reduce reliance on fossil fuels.
Substantial Financial Savings

One of the most striking outcomes of this project is the complete elimination of electricity bills for the sawmill. By harnessing solar power, the facility has drastically reduced its dependence on expensive grid electricity. Additionally, the integration of the generator has led to a 70% reduction in fuel costs during daytime operations, further driving down operational expenses.

284kWp Solar Capacity

This substantial capacity ensures that the sawmill can generate enough power to meet its daily operational needs.

3 x 100kW TAURO-ECO Fronius Inverters

These high-efficiency inverters are essential for converting the solar energy into usable electricity. The Fronius TAURO-ECO series is known for its durability, performance, and suitability for large-scale industrial applications.
