Unfortunately, the number of solar hours was disappointing, but even so, 9 kWh of renewable electricity was generated through the PV panels during this period. In addition, it still required 21.6 liters of diesel to cover the entire consumption, significantly less than a conventional diesel generator that consumes as much as 204 liters of diesel over the same period. Thanks to the combination of the PV panels with the available battery, as much as 76% of running time was saved on the genset. In addition to 182 liters of diesel, a saving of over 650 kg in CO2 emissions and almost 1 kg in NOx emissions was thus realized.
Due to the higher rental price than a conventional genset and the disappointing weather, the Solar Genset in this case turned out to be €1.66 more expensive over the entire period than a conventional genset. On the total cost, however, that is of course a minimal difference. This makes it very financially justifiable to choose a sustainable and green solution. Moreover, over a longer period than 5 days or slightly more sunshine, the solar aggregate is undoubtedly cheaper, so we hope to be back at the next elections as well!
