PV Service Description

Frequency/ Response

Time

Visual inspection of Solar Facility’s general site conditions, PV arrays, electrical equipment, mounting structure, fence, shading, trackers, vegetation, animal damage, erosion, corrosion, and discolored panels.

Every 6 months

Visual inspection and correction of Solar Facility for loose electrical connections and ground connections.

String-level open-circuit voltage, DC operating current tests, and I-V curve traces on 100% of all strings.

1x per year

4 All switches and disconnects tested to ensure they are not jammed.

Infrared scans on 100% combiner and re-combiner boxes; tighten connections to manufacturer's torque specification; report broken terminal blocks.

100% check calibration expiration on sensors and meters, including pyranometers, and anemometers and perform other service such as cleaning and replacement of any desiccant.

Turn off and on logging and communications to ensure they are communicating and ensure battery backups are working.

See 9-12

9 Clean inverter cabinet air vents.

10 Clean and change inverter air filters, if present, per manufacturer’s warranty requirements.

11 Clean/remove dust from inverter heat sinks per manufacturer’s warranty requirements.

12 Check torque marks and re-tightening appropriate wiring connections to design specification torque force per manufacturer’s guidelines.

13 Inspect roof penetrations to ensure sealant is applied properly and not degrading.

14 PV array module maintenance for all modules See 15-16

Wash all panels with water with no chemicals in a method approved by the

Owner.

16 Perform infrared scan of 100% of modules for two types of circuitry connections: cells on the front and junction boxes on the back.
