The DC cables are connected to 19 utility-scale central inverters, each rated at 4 MW ac, giving the PV system a rated AC power output of 76 MW ac, which corresponds to an inverter loading ratio of 1.32. The inverters are made in Europe in a plant that produces 250 of them each year. These inverters are not subject to import tariffs.
While they cost more than string inverters, averaging $1.15 per watt, they offer the benefit of independent panel optimization. For a 5 kW system, the cost is approximately $5,750. Microinverters generally come with warranties of around 25 years, which aligns with the expected lifespan of the solar panels themselves.
Technology Description: This scenario assumes inverter design simplification and manufacturing automation result in an inverter price of $0.03/W DC. Justification: The power electronics industry already has roadmaps to simplify and automate current products, and there is more potential with increased industry size.
