The introduction of the “Loi sur l’Energie” has set ambitious objectives for the proliferation of renewable energies in Switzerland. The electricity production from solar panel has been set at such high fraction of the rest, that its deployment will inevitably create a strain on the national grid. The increase of energy from photovoltaic panel is concentrated during the hottest hours of the day but this does not correspond to the general behavior of power consumption.
The objective of the project is to modify the typical production curve to match more closely the daily energy consumption. Through an optical approach, we developed masks whose goals are to increase the apparent surface and thus the production when the solar incidence angle is high.
The energy production being naturally lower when the sunlight is less intense, we also developed a specific electronic to take into account the needs of the prototype and improve the efficiency of the conversion of electricity at low power.
