PV Array Requirements
Equipment and Installation Recommendations
Equipment
recommendations • All electrical equipment should be approved for the voltage and current
ratings necessary for the application.
• All wiring should be sized correctly to minimize voltage drop.
• All exposed wires or conduits should be sunlight resistant.
• All required overcurrent protection and disconnecting means should be
included in the system and accessible for maintenance.
Installation
recommendations • All electrical terminations should be fully tightened, secured, and strain
relieved as appropriate.
• All mounting equipment should be installed according to the manufacturer’s
specifications.
• All wires, conduit, exposed conductors and electrical boxes should be secured
and supported according to code requirements.
MPPT Requirements
MPPT operational
window The MPPT software maximizes the output energy of solar arrays as long as the
operating voltage is within the MPPT operational window. Ensure that the PV
array used in the system operates within the MPPT operational window.
Effects of array voltages outside of the MPPT operational window are shown in
Table 2-1.

Important:
The PV array should be free of shade. This requirement includes even
small obstructions such as antennas, chimneys, and power lines. As well, be aware of
potential obstructions from growing trees and neighboring buildings. A small amount of
shade can have a disproportionately high impact on system performance.
