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 off-grid solar system installed at the Clarens Guest House includes a robust 10kW Victron inverter, providing sufficient power to support both the main residence and the guest accommodations. The system is complemented by a substantial 25kWh battery backup, ensuring continuous power supply even during periods of low sunlight or power outages.

With a 12.5kWp solar capacity, the system efficiently captures and converts solar energy to meet the energy demands of the entire property. This integration not only reduces energy costs but also contributes to environmental sustainability by minimising carbon emissions.

The off-grid setup eliminates dependency on the national power grid, providing the guest house with a reliable and consistent energy source. This ensures that guests experience uninterrupted services, enhancing their overall stay and satisfaction.
