Background:

Our customer, SolarEnergia Ltd., is a manufacturer of solar modules for residential and commercial installations. They are committed to delivering high-quality, efficient, and durable solar panels to meet the growing demand for renewable energy solutions. As an industry leader, SolarEnergia continuously explores innovative technologies to enhance the performance and reliability of its solar modules.

Recently, they faced a significant challenge in optimizing the performance and lifespan of their solar modules. Traditional materials used for the circuit boards in solar modules had limitations in terms of heat dissipation, environmental resistance, and dimensional stability. These limitations resulted in reduced energy conversion efficiency and a shorter overall lifespan of the solar modules.

Solution:

When SolarEnergia viewed our website, they reached to us and asked for what they wanted and their challenges and concerns. After analyzing together, we proposed the adoption of DPC ceramic circuit boards in their solar modules. DPC technology offers superior thermal conductivity, excellent environmental resistance, and exceptional dimensional stability. These features make DPC circuit boards an ideal solution for the demanding requirements of solar module manufacturing. We designed and fabricated the ceramic PCB with expedited service, and finally, customer received the boards within 2.5 weeks.

In addition, due to the copper foil covering a large area on the ceramic PCB surface, our operator put the un-vulcanized paper between each board to avoid the boards be oxidized.

Result and Benefits:

SolarEnergia expressed great satisfaction with the implementation of DPC ceramic circuit boards in their solar modules. The improved heat dissipation capabilities of DPC technology resulted in an average energy conversion efficiency increase of 3%, leading to enhanced overall system performance. They said we are the only one ceramic PCB supplier that they want to cooperate again in China.
