Photowatt built into its DNA three fundamental commitments: sustainable developement, quality and innovation. Fron the beginning these commitments have been guiding the actions of the company.
Photowatt makes a priority of meeting strict environmental standards so as to achieve consistency between its operations and practices, whether in terms of limiting its carbon footprint, organizing panel recycling or adhering to the profession’s best practices.
Given the importance of protecting intellectual property, Photowatt has filed several patents, including patents for the isotropic acid texturizing method, the simultaneous formation of n+p and pp+ joining through co-diffusion and the integration of bypass diodes in the laminate.
Two focus areas
Strong with this scientific and technical capital, our R&D team focuses on two main areas: accelerating the incorporation of incremental innovations into the manufacturing process and anticipating breakthrough innovations.
Major projects are implemented through collaborative partnerships with French and European academic laboratories (INES-CEA, CNRS, universities, engineering schools and so on) and manufacturers, all leaders in their fields.
Ongoing improvement in manufacturing
At each stage of production, the company optimizes processes with a dual goal: increasing quality and reducing production costs.
Made in our factories in Rhône-Alpes
Connectorrs MC4 or equivalent
IP65, for efficiency protection against corrosion
Cables and diodes welded for better pull-out strength, exceeds the standard (500N)
Semipermeagle membrane Gore-Tex, forming a water and dust barrier
Optimum temperature management reducing losses of energy yield
Electric insulation and very long-lasting waterproofness in environments ultra demanding
50% less reflecting
Resistant to washing/cleaning and to abrasion
Pioneer of the photovoltaic, we have over 40 years of experience and know-how
CONTROLS OF QUALITY
Photowatt also makes quality controls throughout its production line. 100 % of modules are the object of electroluminescence inspection (EL) to eliminate the defects at the heart of materials, dielectric controls and measure I/V are made thanks to a solar simulator AAA present in our factories. Finally, The controls of calibration of our equipment of metrology are realized with a frequency at least 4 times superior to the standard by independent institutes (e.g. Fraunhofer Institute).
TESTS SUPERIOR TO THE STANDARD
Photowatt realizes tests on the whole production line, what allows to have sustainable and reliable, quality products in time. Photowatt meets the requirements standards IEC, but also pushes its more far internal tests such as the climatic tests; the tests hot season wet realized in our laboratory make 2000 a hour minimum, the tests cyclage thermal 400 cycles minimum, the tests frost/thaw 20 cycles minimum. The mechanical tests are also hard and test PID free are in class.
