Company Profile:
LST Energy Co., Ltd. is a company based in Seoul, South Korea. Since the foundation in 2002, the company is trying to find the way using new and renewable energy, such as photovoltaic, wind power and hydrogen, based on semiconductor technology. The company provides materials and components, such as junction box, EVA, ribbon, glass, frame, inverter, diode, IGBT, and etc., to PV module manufacturer and PV system installer.

LST Energy Co., Ltd. – Junction Box Diode for Maximum Power Output and Efficiency

What we offer:
LST Energy deals with materials and components for PV module manufacturer and PV system installer. Particularly, our innovative diode for junction box provides maximum output power and efficiency for PV module. It eliminates hot spot, improves product life, and advances efficiency.

This innovative diode prevents forward current from flowing backward. Even tough Reverse Voltage increases to 60V, Vf is sustained as 0.45~0.55V, and the temperature of solar cell does not rise. Its uniform temperature eliminates hot spot, therefore it prevents loss and damage of PV modules. Also it can prevent yellowing of PV products such as EVA & back sheet.

It is suitable for bypass diode of solar panel junction box.

What are we looking for:
LST Energy is looking for a sales and service partners in junction box manufacturing industry who is able to apply the innovative diode to their own junction box for PV modules. The ideal partner shall be active on the local market and has capability to install our diode to own junction box.
