In the last few months we had solar panels installed on the new factory and also acquired a conveyor reflow oven, which helps to automate our process and reduce board faults that may occur from manual handling.
The solar panel people thought our requested quantity of solar panels (10kW) was excessive compared to our electricity usage. However, they hadn’t seen the conveyor reflow oven in action. While our non-manufacturing usage is typically well under 4kW except for when the kettle is used, manufacturing appears to peak at 18kW on each phase! Fortunately we use 100% green energy.
