While PV modules and inverters still represent the highest share of the initial capital expenditure of a large-scale PV system, there are other costs, including balance of system components and operations and maintenance, that will have a key role in PV system economics in the coming years.
Thanks to technological improvements in solar modules and power electronics, the cost of these components has declined significantly over the last decade. Future contributions to further savings can be achieved by looking at these technologies from a different perspective.
ABB is proposing a new approach to inverter design, which is said to ensure optimal integration with the transformer station. The company claims that the new Intersolar award-winning PVS-175 inverter, which is the result of this approach, demonstrates how inverter technology can effectively support the solar industry.
To date, we don’t know of other >100 kW string inverters which have 12 maximum power point trackers. In the upcoming pv magazine webinar, ABB’s Global Product Manager Marco Trova will discuss the new inverter concept, which ABB says can integrate the transformer station and save on combiner boxes, and explain how this concept is expected to increase yields and reduce costs.
The webinar will also clarify how ABB is seeking to shift the paradigm in inverter design, and identify other areas for cost optimization while preserving the system yield, in a scenario in which system cost breakdown is rapidly evolving towards a higher share for BoS and O&M.
