The purpose of this Statement of Work is to ensure the entire photovoltaic systems for this facility are maintained according to manufacturer’s recommendations to ensure the readiness and proper operation of the system. All maintenance requirements are callout in IEC62446-12016 (Photovoltaic (PV) systems – requirement for testing, documentation and maintenance).

A. Annual Schedule

1. Conduct visual inspection of photovoltaic system.

• Check for evidence damage to photovoltaic panels.

• Inspect wiring harness for wear and damage.

• Inspect supports damage and stability.

• Inspect system for corrosion.

• Inspect inverters and replace if needed.

• Fuses – Inspect and adjust/replace if needed.

• Check photovoltaic system to ensure that vegetation is removed or controlled under and over photovoltaic.

2. Panel inspection and cleaning:

• Check each connection for voltage and current output

• Soiling and resulting cleaning regimen depend on local sources of dirt. (agricultural dust, construction dust, pollen, bird population, diesel soot, industrial sources, snow, sand and lack of rain). Area climate may result in a more often cleaning this will be determined by the monitoring system and the drop off of production of the overall system.

• Infrared all panels for hot spots on the panel which results in a panel failure

• Infrared all cable connections.

• Check disconnects for DC system.

• Test grounding on each panel it should be close to zero

• Two tests methods are possible (short circuit test or operational test) and both will provide information on the correct functions of the PV panels

3. DC disconnect cleaning and inspection

• Replace input filters on disconnection system

• Inspect fans for proper operations and damage

• Replace output filters on disconnection system.

• Test output DC system for quick release and break of connection

• Test GFCI system and insure that the system is protected space.

• Polarity of all DC cables shall be verified using suitable test apparatus

4. Inverters.

• Inverter preventive maintenance for each inverter per manufacturers operating guideline

• Clean inverter cabinet air vents

• Clean and change inverter air filter, if present, per manufacturer requirements

• Clean and remove dust from inverter heat sinks per manufacturer requirements

• Check torque marks and re-tightening appropriate wiring connection to design specification torque force per manufacture requirements.

• The potential for the system inverter to produce a DC back-feed into PV array circuits shall also be verified. It should also be verified that any back-feed current is lower than the module maximum fuse rating and the string cable ampere rating.

• There some mains to the inverter on the AC side that have to be isolated

• The inverter operational parameters operation as programmed and designed.

• All DC junction boxes (PV generator and PV array boxes) carry a warning label indicating that active parts inside of boxes are fed form the PV array and may still be energized after isolation from the PV inverter and public supply.

• Inverter type

▪ AC Module: no Dc test or inspection work required

▪ Micro inverter: testing of DC circuits is required; inspection of DC works is required.

▪ Module integrated electronics: Where possible a standard test regime to be followed, manufacturer to be consulted to determine any restrictions to tests, manufacturers to be consulted on pass/fail criteria for tests.

• Once polarity is confirmed, cables shall be checked to ensure they are correctly identified and correctly connected into system inverter.
