Off-grid safety requirement
Module Quality
Certified panels, verified datasheets and traceable serial numbers.
Solar modules are the generation source of the off-grid system. Quality checking confirms that the selected panels are suitable for the site, compatible with the controller/inverter limits and supported by proper warranty records.
Why It Matters
Panel quality directly affects daily energy generation and battery recharge time.
Certified modules reduce the risk of early degradation, hot spots and warranty disputes.
Serial-number records make warranty claims and future replacement easier.
Required Checks
Module wattage, voltage, current and temperature coefficient from datasheet.
Module quantity and string voltage within charge controller or inverter limits.
Shade-free layout, tilt, orientation and cleaning access.
Glass, frame, junction box and connector condition before installation.
Manufacturer warranty, product warranty and performance warranty terms.
Required Documents
Module datasheet.
Module warranty document.
Serial number list.
Panel layout drawing.
Site photos and shadow observation record.
Installation Details
Use compatible DC connectors and correct polarity.
Route module cables away from sharp edges, water collection and walking paths.
Keep module clamps and fasteners as per structure design.
Record final module count, wattage and installed position.
Handover Records
Installed module brand, model, wattage and quantity.
Final panel layout and serial-number sheet.
Warranty cards and datasheets.
Cleaning and visual inspection guidance.
Service Notes
Clean panels based on local dust level and water quality.
Inspect cracked glass, loose connectors, hot spots and damaged cables.
Avoid new shade from tanks, antennas, trees or nearby construction.
