Hybrid Solar-Diesel

Hybrid Solar-Diesel

Hybrid solar-diesel advantages

  • Cost savings (diesel fuel, CO2 emission rights)
  • Risk mitigation (grid failure, diesel theft, diesel price inflation)
  • Significantly enhances life of the generators and lowers the frequency of maintenance
  • 30 years + panel life

More than 50% Fuel Savings

Today it is possible to achieve more than 50% fuel savings by adding photovoltaic solar panels (PV) to diesel generators. During the day, the solar panels will provide most of the electricity and generators will either run idle or switch off. A hybrid system in combination with batteries, makes it possible to completely turn off the gensets during most of the day. On a cloudy day or at night, the generators will then take over again. This makes for maximum fuel savings and a 100% reliable energy system. Consumers with mainly daytime consumption (cooling, airco, pumping, grinding, etc.) can save more than 90% of their fuel consumption.

Quick payback

Depending on the fuel price and solar irradiation, it is in some parts of the world possible to recover the total investment in less than 2 years. Given that dual glass solar panels have an output guarantee of 30 years, this means, free daytime electricity for the remaining 28 years.

New or existing generator(s)

Solar panels can be added to both new and existing generators to save diesel fuel. The fuel save system can interact with more than 100 generators if needed.

For medium to large electricity consumers

This solution can be applied to SMEs, farms, communities and very large industrial- or mining corporations. It is possible to implement a fuel save system from as low as c. 50kW, but usually it applies to systems from c. 200kW to +20MW. For communities the hybrid solar diesel solution can be used in combination with pre-paid card or mobile payment meters. Diesel back-up systems on the other hand can be implemented from as low as single digit kW systems (i.e. households).

The electricity produced by the solar system is usually 3x400V and can easily be transformed up to mid-tension voltages (10.000-15.000V) and transported over several kilometers to where it is needed.

1 MWp

1MWp (4000 panels) in the sunbelt (Africa, Middle East, Latam, Asia):
– Produces 1,5 – 1,8 GWh per year
– Requires 1 ha of surface
– Saves 375.000 – 450.000 L fuel per year = more than a truckload of fuel a month
