Maintenance of Solar PV System Equipments
We recommend carrying out periodic Maintenance for our Solar Power System. Followings are the
Guide Points for the Same.
Module Mounting Structure:
Quarterly Check Below Points:-
•
Tightness of the all the fastener with proper torque with the use of the torque wrench.
•
Galvanizing layer of the structure components.
•
Foundation on which structure is installed.
•
All the fasteners, nuts/ bolts must be free from corrosion.
•
Module mounting on the structure, must be align & tight properly.
•
Structure must be withstood with 150 Km/Hr. capacity of wind flow.
•
SPV structures should be designed in such a way that all solar panels can be easily reached by
human hand for regular cleaning.
Solar Modules:
General Check List:
•
Each structure should be facing south but tilted at an Angle From the Horizontal Ground Level. They
should be tilted from the horizontal at a degree equal to the latitude of the Site Location.
•
All the structure should be located in such a way that no shadows of any adjoining trees or building or
structures fall on any solar panel at any time of the day.
•
Space between two rows of solar structure should be at least twice of the height of the Solar panel
structure at the highest point of Tilt. This minimum space is required to avoid shadow of one row of solar
structure to fall on the row behind it.
•
There must not be any obstacles near to PV Module installation area, So that shadow will affect the
generation.
•
Do not step or walk on the Modules or else the warranty of the modules will be void.
•
During the generation hours there should not be any shadow reflect on PV Modules as it will Create
Hotspot & Burn the Module.
Weekly:-
•
All PV Modules must be washed with PURE WATER for the better Power Generation.
•
Note: Please Do Not Wash or Clean the Module during Generation Hour (Between 8.30 AM To 5:00PM),
As it will REDUSE Life of the Module.
•
All the modules must be free from Dust / Bird’s Drop, As It will Affect the Generation &
•
Decrease The Efficiency of the Module.
Solar Inverter:
We Recommend Carrying the Periodic Maintenance of the System by Authorized Service Engineer.
Quarterly Check Below Points:-
•
All Electrical Power Connection for Tightness.
•
Verify the Grid, Output, Array Cabling and Its Termination.
•
Check Inter Cell Connectors for Tightness and Corrosion on Terminals.
•
Ensure the Ventilation and Cleanliness Surrounding the ESU.
•
Clean Front Air Filters by using Blowers.
Yearly Check Below Points:-
•
Apart from Above, Open the ESU and Check the Power Transformer Cable Connection.
•
Working Condition of ESU Exhaust Fan.
•
Physical Condition of DC Capacitors and AC Capacitors.
