STMicroelectronics intelligent device reclaims lost solar energy with Intelligent Hotspot Prevention

STMicroelectronics today announced an innovation for solar panels aimed at allowing more of the energy from each cell to reach the power grid. The innovation replaces the simple bypass diode with an intelligent device that enhances efficiency and offers the same package outline. STMicroelectronics’s new SPV1001 contains a low-loss power switch and a precision controller. Directly replacing bypass diodes, which are used to prevent hotspot effects, the SPV1001 protects the energy normally lost in each diode. Compared to the use of diodes, the integrated power switch provides negligible leakage current when the photovoltaic (PV) panel is producing energy.

STMicroelectronics’s new SPV1001 can deliver a fast Return-On-Investment, in terms of releasing additional energy for solar panel applications. In addition to package options enabling one-for-one replacement of bypass diodes in the solar panel’s junction box, the SPV1001 is available in an MLPD package that can be laminated directly into the panel, due to the device’s ultra-low-profile and minimal power .
