7​ Scope of work for O & M:-

7.1​ Operation and Maintenance Guidelines for works of Grid Connected SPV Plant under this rate

​ For the optimal operation of an SPV plant, maintenance must be carried out regularly by

​ 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 the agency for various components viz. solar panels,

inverter, wiring, etc. are discussed below: -

7.2​ SOLAR PANELS: -

a)​ The SPV panels must be cleaned at least once every Fifteen days & maintain a register for same.

b)​ Any bird droppings or spots must be cleaned immediately.

c)​ Use water and a soft sponge or cloth for cleaning.

d)​ Do not use detergent or any abrasive material for panel cleaning.

e)​ Isopropyl alcohol may be used to remove oil or grease stains.

f)​ Do not spray water on the panel if the panel glass is cracked or the backside is perforated.

g)​ Wipe water from a module as soon as possible.

h)​ Use proper safety belts while cleaning modules at inclined roofs etc.

i)​ The modules should not be cleaned when they are excessively hot. Early morning is a

M particularly good time for module cleaning.

j)​ ​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.

k)​ Ensure that the module terminal connections are not exposed while cleaning; this poses a risk

of electric shock.

7.3​ CABLES AND CONNECTION BOXES:-

a)​ Check the connections for corrosion and tightness.

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

c)​ There should be no vermin inside the box.

d)​ Check the cable-insulating sheath for cracks, breaks or burns. If the insulation is damaged,

replace the wire.

e)​ If the wire is outside the building, use wire with weather-resistant insulation.

f)​ Make sure that the wire is clamped properly and that it should not rub against any sharp edges

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

h)​ Ensure that all underground cables are laid properly and enclosed in protective DWC pipes.

RMC/ROSHNI/SOLAR/2026​ ​ ​ Page 39 of

7.4​ INVERTER:-

a)​ The inverter should be installed in a clean, dry, and ventilated area which is separated from,

and not directly above, the battery bank.

b)​ Remove any excess dust in heat sinks and ventilation. This should only be done with a dry

cloth or brush.

c)​ Check that vermin has not infested the inverter. Typical signs of this include spider webs on

ventilation grills or wasps’ nests in heat sinks.

d)​ ​Check functionality, e.g. automatic disconnection upon loss of grid power supply, at least

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

7.5​ SHUTTING DOWN THE SYSTEM: -

a)​ ​Disconnect system from all power sources in accordance with instructions for all other

components used in the system.

b)​ Completely cover system modules with an opaque material to prevent electricity from being

generated while disconnecting conductors.

c)​ To the extent possible, a system shutdown will not be done during daytime or peak
