Services and Benefits

With our complementary experience in the field of photovoltaics, architecture and technology, we advise and support you in your solar integration projects by helping you to understand the existing products and to make the best choices for your project. We also accompany you in the questions of strategy of the deployment of solar technologies within municipalities and/or communities, from an urban planning as well as from a financial point of view.

Who we are

Laure-Emmanuelle Perret

Laure-Emmanuelle Perret received her PhD in chemistry from the University of Fribourg in 2004. Her involvement in solar energy began when she joined Christophe Ballif's team in EPFL’s PV-Lab in 2009 as group leader of the back-end activities related to PV modules. From 2013 to 2018 she worked at the CSEM PV-center in Neuchâtel as head of the Module Technology sector and now coordinates the European Be-Smart project for EPFL.

As a passionate and committed scientist, she will put her technical knowledge and her network of experts at the service of your project, in a collaborative and interdisciplinary spirit.


Angela Clua Longas

Angela Cluá Longas, architect, obtained her PhD in architecture at EPFL in 2019. Talented and passionate, she is a specialist in sustainable architecture and an expert on the development of high energy performance facades (active and passive), who will put all her knowledge at the service of your project.

Sensitive to the harmony, the proportions and the coherence of the project, Ángela Cluá Longás has mastered the Swiss standards and recommendations in the field of construction, particularly in relation to sustainable construction and the energy efficiency of buildings. Her great creative capacity in the design of projects and their constructive solutions brings to LMNT a valuable expertise that will be put placed at your project’s disposal.

An active building element

Building Integrated Photovoltaics (BIPV) will undoubtedly play an increasingly important role, especially in cities and urban areas. Indeed, our cities offer a large number of surfaces available for the exploitation of solar energy, including flat roofs, industrial buildings, facades and new constructions. The amount of energy that could be supplied in this way is estimated at 22% worldwide. The solar panel is thus becoming a building element in its own right and enters the mindset of the construction world.


Coopératives des Cheminots, Neuchâtel

Study for the integration of terracotta-coloured solar panels on all the roofs of the buildings of the Coopérative des Cheminots in Neuchâtel.

A particular architectural solution had to be established to meet the site’s heritage constraints.

Services included visual simulations and performance and cost evaluations.



Evaluation of a solution allowing the integration of solar panels on the roof of an old protected mansion and evaluation of a new heating system.


Des éléments actifs colorés

Château d'Auvernier

Evaluation of the solar potential of the Château d'Auvernier.

Services included simulations of different solar integration possibilities, cost and profitability performance calculations.

Trompe l'oeil solaire

Trompe l'oeil energy producer

This solar trompe l'oeil is installed in a garden in downtown Neuchâtel. A high-resolution photograph has been integrated into the solar panel thanks to the technology developed by the CSEM and the company Solaxess. The current produced by this photograph is injected directly to its owner’s system. The total installed power is 900 Wp.
