Your bankable partner for large-scale PV projects

Quality is our mission and driving force. At Stäubli Renewable Energy, we offer you a strong base for sustainable success. We can help you improve the profitability and the ROI (return on investment) of your PV project with quality product solutions and services for eBOS (electrical Balance of Systems) that contribute significantly to obtaining a low LCOE (levelized cost of energy), the deciding factor when it comes to the long-term profitability of a power plant.

The Lifelines of PV system
eBOS components and especially PV connectors are the lifelines of a PV system. Numerous studies and our experience in the field have documented that connection failures directly impact a project's financial success. It is common for low-quality components and improper handling to cause incidents that take time to repair or even cause downtimes. Ensuring your PV system has quality connectors can mitigate costly outages affecting an entire string of panels. From optimizing CAPEX to minimizing technical issues for higher yield and a lower OPEX – we add value along the entire lifecycle of your PV project with our quality products and services.

Our solutions provide the highest quality products and services to ensure long-term and reliable performance, giving you the ultimate peace of mind. It is always best to rely on the Original MC4 PV connector to avoid unnecessary risk and failures. And our highly skilled service and support teams ensure that everything runs smoothly and meets your product-specific needs.
