Frequently Asked Questions

There are two main reasons for underperforming solar arrays:

1. Natural Degradation:
   PV modules lose about 0.4% efficiency per year on average, with variations depending on the manufacturer and material quality.
2. Mechanical Issues:
   • External Damage: This includes backsheet failures, broken glass or damaged cabling.
   • Internal Damage: Issues such as encapsulation failure, delamination or photovoltaic cell degradation.

Visual Inspections

Perform a visual inspection of your PV modules and ancillary components (for example, inverter, wiring).

Important Safety Note:

• Never touch active components with your hands or body during inspections. Electrically charged metal frames, racking or even water on the ground can cause serious electrical shocks.
• If you're uncertain or inexperienced, hire a licensed professional to ensure safety and accuracy.
•  

What to Look For:

• Front Side (Sunny Side): Hot spots, cracks, discoloration or broken glass.
• Backside: Linear cracks, bubbles, brittleness, voids or discoloration of the backsheet.

Backsheet damage must be addressed promptly to prevent moisture ingress, which can degrade photovoltaic cells. For detailed inspection, consult Revive PV.

Professional Inspections

While visual inspections can identify some issues, systemic or electrical problems require professional tools and expertise:

• I-V Curve Testing: Diagnoses array performance.
• EL (Electroluminescence) and UVF (Ultraviolet Fluorescence) Testing: Non-destructive techniques to identify internal defects invisible to the naked eye.

Contact Revive PV to schedule a professional evaluation.

The backsheet is the protective rear layer of a PV module, shielding internal components from environmental exposure. Over time, UV radiation, temperature changes and moisture can degrade the backsheet, leading to performance issues and potential safety risks.

Neglecting backsheet damage can have serious consequences:

• Performance Loss: Reduced energy output and revenue.
• Moisture Penetration: Corrosion of busbars and internal components.
• Hot Spots and Fire Risk: Localized heating from damage that can ignite the backsheet, causing potential fires.

1. Degradation:
   • Cracking, yellowing or delamination from UV exposure and environmental stress.
2. Moisture Ingress and Corrosion:
   • Moisture penetration causing corrosion of busbars and solder joint and reducing efficiency.
3. Hot Spot Formation:
   • Localized heating damaging PV cells and reducing module performance.
4. Fire Risks:
   • Severe hot spots igniting the backsheet, posing a fire hazard.

• If you have an operation and maintenance team or engineering, procurement and construction provider: Engage them to safely remove and palletize your modules.
• If not: Contact Revive PV for assistance with removal and logistics.

Important Safety Note:
Ensure all electrical connections are de-energized before handling PV modules to prevent shocks or accidents.

Refurbishment involves repairing and reconditioning solar modules to extend their lifespan and improve energy output. Revive PV specializes in backsheet restoration and other critical repairs.

This version includes clear safety notes at relevant points to ensure user safety while troubleshooting or handling their PV system. Let us know if additional adjustments are needed.
