To calculate the minimum string size, we must first calculate the minimum output voltage, Module Vmp_min, each module will produce for the specific installation site. Then, divide the inverter minimum voltage by the calculated Module Vmin to get the minimum number of modules.

As of 2019, conversion efficiency for state-of-the-art solar converters reached more than 98 percent. While string inverters are used in residential to medium-sized commercial, central inverters cover the large commercial and utility-scale market. Market share for central and string inverters are about 36 percent and 61 percent, respectively, leaving less than 2 percent to micro-inverters. The period between 2009 and 2012 included unprecedented downward price movement in the PV mar.

The DC/AC ratio (also called inverter loading ratio or ILR) is the ratio of total DC array capacity to the inverter's AC output rating. DC/AC Ratio = Total DC Panel Capacity (Wp) / Inverter AC Rating (W) A 10 kWp array connected to an 8 kW inverter has a DC/AC ratio of 1.
