String Sizing Tool is a free, web-based resource that enables designers to determine the optimum string size for a specific photovoltaic module and FIMER solar inverter combination.

This tool requires users to specify the design site location, low and high temperatures, the PV panel and the inverter. Once this criteria is selected, the tool calculates all the allowable string configurations which provides the designer with options to choose the most appropriate design for the solar installation.
