Partnerships

Five partnerships are on record, tiered core, flagship and minor.

• RABLEcoreTechnology or IntegrationPartnership with RABLE, developer of Netherlands' first foldable lightweight mounting system for flat roofs. RABLE's mounting system requires 80% fewer roof anchors than standard systems, reduces installation load, and enables solar on moderately construction-limited roofs without structural modifications.
• SolargecoreTechnology or IntegrationPartnership with Dutch solar panel manufacturer Solarge for lightweight solar panels weighing 5.5 kg/m² - half the weight of standard panels. Solarge panels are fully recyclable (worldwide unique), with the company taking responsibility for end-of-life collection and material reuse. The panels can be used on both flat and sloped roofs.
• HyET SolarcoreTechnology or IntegrationExclusive partnership for Powerfoil® 1300, extremely lightweight solar foil weighing just 0.6 kg/m² - 98% lighter than standard solutions. The ATEX Zone 2 certified foil is suitable for fire and explosion-risk environments and can cover up to 90% of roof surfaces. Manufacturing has 80% smaller CO2 footprint per Wattpeak compared to traditional panels.
• Kenter GroendusflagshipStrategic or Co-development PartnerGroendus and Kenter merged operations to form 'Kenter Groendus', combining their expertise to provide clean and reliable energy for Dutch businesses.
