MV3 System

The simple and effective interface solution between roof structure and photovoltaic panels

The MV3 system was designed to facilitate roof integration of all photovoltaic modules onto metallic, wooden or concrete roof structures. This system perfectly fits into a traditional roof, the watertightness catch up are easily and quickly carried out. The MV3 system enables covering of large scale buildings, from industrial buildings to agricultural buildings and office buildings. There is no photovoltaic surface limit when using the MV3 structure and quite the contrary, the bigger the surface is, the quicker and more effective is the installation.

MV3

Reliability & long life

  • Control of expansion stresses between roof structure and photovoltaic modules
  • Materials used are recyclable and selected for long-term weather-resistance (aluminium profiles, stainless steel fastenings, etc.)

Optimization & profitability

Can be cantilevered up to 0.64m above the ridge purlin and 1m below the gutter, equalling an extra module per vertical array

System without underlay for enhanced module ventilation to increase installation output by 5 to 10% (on-site data recorded for over 12 months)

Easy to set up and install

  • Designed in close collaboration with qualified professional installers
  • High installation productivity with 60 m² put in place per day (including removal of existing roof covering) by 3 people (approximately 40 modules)
  • Only a few tools required
  • The underside can be worked on so that roof covering and cabling can be carried out as separate operations

Maintenance & monitoring

  • The system has no areas which are vulnerable to dirt build-up or moss growth, ensuring that your roof staysclean all year round
  • Access to the cabling connections from inside the building (without removing the modules) means work on the system can be carried out faster and without worrying about the weather

Design

  • The system blends in aesthetically with the roof structure on the outside of the building and gives an exceptionally good finish on the inside
  • Aluminium profiles can be treated with coloured lacquer in a colour of your choice (black, blue…)

Adaptability & flexibility

  • All types of framed modules
  • All types of roof structure, direct fixation on purlins
  • All types of sloping roof from 5 to 50°
  • All types of side finishes can be used
  • Maximum weight of 5.5 kg/m²

Training

MECOSUN, which is officially approved as a training organization, provides you with training and assistance through a course on system installation. The day-long course provides you with the best possible advice for your first installation and also gives you our materials warranty.

  • With MECOSUN building integrated photovoltaic systems, you can ensure that your building roof is weathertight thanks to our patented system using a mechanical drainage principle.
  • Not only that, as our system does not require an underlay, you get higher module output and the highest feed-in tariff in countries with the respective legislation.
