Annexure-C

OPERATION & MAINTENANCE (O&M)

The bidder shall be responsible for operation and maintenance of the Rooftop Solar PV system for a

period of 5/25 years for the projects as per the condition of PO, during which CEL will monitor the

project for effective performance in line with conditions specified elsewhere in the bid document.

During this period, the bidder shall be responsible for supply of all spare parts as required from time to

time for scheduled and preventive maintenance, major overhauling of the plant, replacement of

defective modules, inverters, PCUs etc and maintaining log sheets for operation detail, deployment of

staff for continuous operations and qualified engineer for supervision of O&M work, complaint logging

& its attending.

SUBMISSION OF O&M REPORT (OMR)

The bidder shall submit the Monthly O&M Report mandatorily to the Employer as per the Format

enclosed at Annexure E. Non submission of the report shall be considered as “Breach of Contract” and

shall attract punitive actions as per the relevant provisions of the Contract. However, the decision of the

CEL shall be final in this regard.

OPERATION OF THE SYSTEM DURING WEEKENDS AND GENERAL HOLIDAYS AND CALCULATION OF

CUF:

During grid failure, the SPV system stops generating. Any instances of grid failure need to be mentioned

in the monthly report and those instances need to be authorised by local DISCOM/CEL. Then the period

will be excluded in calculation of CUF.

Operation and Maintenance Guidelines of Grid Connected PV Plants

For the optimal operation of a PV plant, maintenance must be carried out on a regular basis.All the

components should be kept clean. It should be ensured that all the components are fastened well at

their due place. Maintenance guidelines for various components viz. solar panels, inverter, wiring etc.

are discussed below:

1. SOLAR PANELS

Although the cleaning frequency for the panels will vary from site to site depending on soiling, it is

recommended that

� The panels are cleaned at least once every fifteen days.

� Any bird droppings or spots should be cleaned immediately.

� Use water and a soft sponge or cloth for cleaning.

� Do not use detergent or any abrasive material for panel cleaning.

� Iso-propyl alcohol may be used to remove oil or grease stains.

� Do not spray water on the panel if the panel glass is cracked or the back side is perforated.

� Wipe water from module as soon as possible.

� Use proper safety belts while cleaning modules at inclined roofs etc.

� The modules should not be cleaned when they are excessively hot. Early morning is particularly

good time for module cleaning.

� Check if there are any shade problems due to vegetation or new building. If there are, make

arrangements for removing the vegetation or moving the panels to a shade-free place.

� Ensurethatthemoduleterminalconnectionsarenotexposedwhilecleaning as this poses a risk of

electric shock.

� Never use panels for any unintended use, e. g. drying clothes, chips etc.

� Ensure that monkeys or other animals do not damage the panels.

of 40



2. CABLES AND CONNECTIONBOXES

� Check the connections for corrosion and tightness.

� Check the connection box to make sure that the wires are tight, and the water seals are not

damaged.

� There should be no vermin inside the box.

� Check the cable insulating sheath for cracks, breaks or burns. If the insulation is damaged, replace

the wire.

� If the wire is outside the building, use wire with weather-resistant insulation.

� Make sure that the wire is clamped properly and that it should not rub against any sharp edges or

corners.

� If some wire needs to be changed, make sure it is of proper rating and type.

3. INVERTER

� The inverter should be installed in a clean, dry, and ventilated area which is separated from, and not

directly exposed to sky.

o Remove any excess dust in heat sinks and ventilations. This should only be done with a dry cloth or

brush.

o Check that vermin have not infested the inverter. Typical signs of this include spider webs on

ventilation grills or wasps’ nests in heat sinks.

� Check functionality, e.g. automatic disconnection upon loss of grid power supply, at least once a

month.

� Verify the state of DC/AC surge arrestors, cable connections, and circuit breakers.

4. SHUTTING DOWN THESYSTEM

� Disconnect system from all power sources in accordance with instructions for all other components

used in the system.

� Completely cover system modules with an opaque material to prevent electricity from being

generated while disconnecting conductors.

� To the extent possible, system shutdown will not be done during day time or peak generation.
