In 2013, LPI EUROPE SL was one of the three (out of more than 750) companies selected for incubation in the 3rd call of Fondo de Emprendedores organized by Fundación Repsol. LPI presented a novel concept to produce photovoltaic solar energy with super-high efficiency: “The high concentration ultra-flat MF45 CPV module”
The project evolved from the need to develop an economically viable and more sustainable energy-model through cleaner energy production. The sun, as a source of inexhaustible and non-polluting energy, is one of the most promising alternatives in the green energy fields. In order to make it competitive and independent of subsidies policies, it is essential to lower the price of the KWh (by both lowering manufacturing costs and by increasing yearly electricity production. The MF 45 module, despite being really simple and manufacturable at low costs, can potentially increase efficiency by 60%, relative to the best photovoltaic (PV) flat panel on the market (two-axis tracking), lowering the electricity generation costs and reducing the footprint needed to build solar plants.
The MF 45 is an ultra-flat high-concentration photovoltaic system (CPV) of very high efficiency, which may convert the equivalent of 45% of solar direct radiation into electricity. This very high efficiency is obtained not only due to the simplicity and high performance of the optical system, but also thanks to the optimal use of solar spectrum (using ultra-high efficiency 4-junction concentration cells (MJ) and the use of diffuse radiation as well by means of low-cost silicon (Si) solar cells panel embedded in the concentrator system.
A MF 45 module with a 6 x 9 array of individual four-channel lenses was designed and manufactured within the scope of the project financed by Fundación Repsol.
