Split an array into subarrays and find the DC rating

Module power at STC (W)

MPPT inputs on the inverter

Inverter AC rating (kW, optional)

Subarray 1

Modules per string

Parallel strings

Tilt (0 to 90 deg)

Azimuth (0 to 360 deg, 180 = south)

MPPT input number

Subarray 2

Modules per string

Parallel strings

Azimuth (0 to 360 deg, 180 = south)

MPPT input number

Subarray 4 (leave blank to skip)

Modules per string

Parallel strings

Tilt (0 to 90 deg)

Azimuth (0 to 360 deg, 180 = south)

MPPT input number

Every starting value is invented (410 W module, 8 kW inverter, two subarrays). Replace them with your own. This sums nameplate watts at STC. It does not check string voltage, current limits or shading, and it does not model energy. Azimuth here is measured from north, so 180 is south; some tools use other conventions, so check yours. Type 2500 or 2,500; 2.5 and 2,5 are read as decimals. Up to 4 subarrays, the limit in SAM's help.
