Solar Energy

Maximizing energy capture and ensuring longevity is essential for photovoltaic (PV) systems. At Sigma, we operate as a contract manufacturer, where customers retain full ownership of their part designs. Our precision manufacturing processes ensure that electrical contacts and power busbars are built exactly to customer-provided prints and models in a “build-to-print” environment. Engineered to meet the highest standards, these components are crafted to withstand extreme weather, UV exposure, and thermal cycling, ensuring your solar systems remain efficient and reliable over time.

Energy Storage

Battery energy storage systems (BESS) and similar applications require precision and dependable components. We manufacture electrical contacts that deliver seamless conductivity and compliance for both industrial and home automation energy solutions.

Grid Infrastructure

Reliable energy distribution is vital for grid systems, and that reliability starts with precision parts. Our power busbars and interconnects maintain grid stability and minimize downtime, providing dependable energy flow where you need it most.

Wind, Hydro, and Alternative

Renewable energy applications rely on rugged components to perform in challenging environments. From wind turbines to hydroelectric systems, our precision-stamped contacts and busbars are engineered for long-lasting, efficient operation.
