Photovoltaic system needs ceramic suction plate, ceramic rack, ceramic top tooth block, top comb pins, side comb plates as below are very hard to machine because it needs high quality control in the flatness, deformation and surface finish and Innovacera make it.

As insulator materials, ceramics are key components of energy saving solutions. Within the energy sector, ceramic components are also used in machinery for energy production, including bearings, plate, rods, valves, seals, spheres, pumps, sheaths, and tubes for wind turbines, gas turbines, oil and gas extraction equipment, and other systems.

 

In addition to their electrical and thermal properties, ceramic parts contribute to the optical enhancement of solar panels. Ceramics play a crucial role in the manufacturing of solar commentators, which focus sunlight onto photovoltaic cells to intensify energy generation. Ceramics, with their ability to withstand high temperatures and harsh operating conditions, serve as ideal materials for the fabrication of concentrator components, ensuring long-term performance and reliability.
