How much does it cost to wire a photovoltaic combiner box
5 square millimeter, 100 meter photovoltaic cable is generally $0. 38, while cables with large specifications and special performance requirements (such as weather resistance, flame retardancy) are more expensive. The raw component cost for a DIY assembly might be 15-20% lower than a factory pre-wired unit. In the field, “assembly” is not just screwing components onto a rail. It involves procurement. And the photovoltaic combiner box, as a key supporting device in the photovoltaic power generation system, can combine multiple photovoltaic components together, reduce the number of lines entering the inverter, simplify the system structure and provide various protection functions. Combiner boxes are designed for installation near the PV array with each series string of solar modules connected to one of the fused/breaker circuits.
