Ground Conditions and Albedo

Site albedo measurement and optimization.

  • Ground cover material appropriate for bifacial gain (light-colored)?
  • Ground albedo measured with albedometer (at least seasonally)?
  • Current ground albedo within expected range (>0.15)?
  • Vegetation managed to preserve rear-face clearance and albedo?
  • Ground surface uniform under all module rows?

Module Clearance and Mounting

Ground clearance per OEM bifacial specs.

  • Minimum ground clearance per OEM spec maintained?
  • No obstructions shading rear face (racking tubes, cross-members)?
  • Module tilt angle optimized for bifacial yield (typically 20-30°)?
  • Row pitch/spacing sufficient to reduce row-to-row rear shading?
  • Rear face of modules free of significant dirt or bird droppings?

Rear Face Module Condition

Bifacial module rear glass and cell condition.

  • Rear glass of bifacial modules clean and undamaged?
  • No discoloration or delamination on rear face?
  • All rear-face cells visible and no cracked cells observed?
  • EL imaging on rear face conducted to detect hidden cracks?
  • Rear Face Module Condition Photo

Bifacial Performance Monitoring

Bifacial gain measurement and verification.

  • Rear-face irradiance sensors installed and measuring?
  • Measured bifacial gain within modeled expectation (typically 5-15%)?
  • Bifacial gain trend stable year-over-year?
  • System Performance Ratio incorporating bifacial gain?
  • Bifacial Performance Notes

Bifacial Cleaning Maintenance

Cleaning protocol for bifacial modules.

  • Cleaning schedule accounts for both front and rear soiling?
  • Cleaning method safe for rear glass (no abrasives)?
  • Soiling ratio measured (front and rear separately)?
  • Rain-triggered cleaning schedule updated seasonally?
  • White gravel/reflective material replenished where depleted?

Optimization Report

Bifacial optimization findings and recommendations.

  • Ground cover improvement recommendations documented?
  • Any clearance or racking adjustments recommended?
  • Rear face cleaning frequency recommendations updated?
  • Bifacial gain trend report delivered to asset owner?
  • Optimization Notes and Recommendations
