PV Diesel Hybrid System Solution

In many regions of the world, power grids are either inadequate or nonexistent. As a result, industrial consumers often ensure their power supply through diesel gensets. Five hundred gigawatts of power from diesel genset provide industrial companies with electricity worldwide. However, fuel costs for the gensets continue to rise.

In addition, if the fuel has to be transported to remote regions, the effective costs increase even more as a result of the necessary storage. At the same time, PV system costs have dropped by more than 50 percent within the last three years: Solar power is often the most economical alternative energy source for remote regions in the world’s sun belt. It simply makes sense to combine PV and diesel systems so that solar irradiation – which is both abundant and free – can profitably be used as an energy source in industrial applications.

In combination applications, the system incorporates features and functionalities of both our off-grid and grid-tied technology, automatically adjusting power and reactive power references with grid support if frequency or voltage drops, or rotating the genset to automatically ensure the most fuel-optimised running mode through various load demands.

Supporting fuel-saving in grid-tied operations, all gensets can be stopped to maximise the penetration from sustainable sources. Automatic changeovers between grid-tied and off-grid in case of mains failure are possible, even during operation. The system is available both as a Power Management solution for systems multiple sustainable power sources, or as a stand-alone solution for retrofits or existing plants.

What are the advantages of a photovoltaic diesel hybrid system?

In contrast to power supply systems using diesel gensets, and despite their higher initial cost, PV systems can be amortized in as little as four to five years, depending on the site and system size, and they have low operating costs.

In addition, PV systems are flexible and can be expanded on a modular basis as the energy demand grows. Compared to pure gensets systems, a photovoltaic diesel hybrid system provides numerous advantages:

  • Lower fuel costs
  • Reduced risk of fuel price increases and supply shortages thanks to optimized planning
  • Minimal CO2 emissions (protects the environment and facilitates CO2 certificate trading)


Photovoltaic diesel hybrid systems can be amortized especially quickly in sunny regions, with little or no grid access. Deif and Royalstar Enerji Sistemleri system technology maximizes the use of solar energy in combination with diesel aggregates. For industries such as mining; raw material processing; agricultural companies such as flower farms and water desalinization systems and tourism facilities with a high energy demand low power generation costs, quick operational readiness, maximum reliability and availability are fundamental. The environmental benefits are also convincing: CO2 emissions and noise pollution are significantly reduced, minimizing the environmental impact. Environmentally friendly and cost-effective? Yes, we can do that.
