Solar And Grid Hybrid Solution For Telecom

With modular design and robust operating capabilities, COOLNET's solar systems can be easily retrofitted onto existing infrastructure,resulting in reduced diesel use, longer service intervals and extended DG operating life. The solution will dramatically lower operating expenses, thereby simultaneously reducing logistic and security costs and concerns.

Our hybrid system can be integrated with diesel generators to form a hybrid off-grid system, increasing the flexibility and reliability of the entire micro grid system. lower dependency on fossil fuels will improve the resistance to risks caused by their volatle prices.

Advantage 

 

  • Solar And Grid Hybrid Solution For Telecom

    This solar & diesel hybrid solution is suitable for areas with good sunshine but no or poor grid.

    COOLNETs solar solution will be the best approach for low and medium consumption sites in remote areas;

    our solar system utilizes sunshine as the primary energy source, and the long standby batteries which store the extra energy will continue to power you up when there is no sunshine.
