Fully-integrated, Smart HCPV
The Sunflower highly concentrated photovoltaic (HCPV) system integrates photovoltaic modules, advanced tracking, unique power optimization, an embedded controller and wireless communication into one elegant solution to produce cost-competitive solar power while reducing installation and maintenance costs.
Features and Benefits

High-Efficiency Module

  • Industry-leading 30% module efficiency
  • 1,200 sun concentration onto high-efficiency, triple junction cells
  • Tempered glass composite primary lens enhances reliability and reduces soiling

Wide Acceptance Angle

  • Advanced optical design yields industry leading +/- 0.9° acceptance angle

Integrated Micro-Tracker Frame-Set

  • Low-profile design enables quicker installation and minimal on-going maintenance
  • Wiring is pre-assembled at the factory; field wiring connection is plug and play
  • Non-penetrating, free-standing, self-ballasting roof and ground mount structure
  • Sealed Micro-Tracker gearbox requires no maintenance

Micro-Converter Technology

  • Optimizes power by providing local MPPT
  • Improves performance of shaded modules
    • Minimal mismatch losses
  • Improves inverter performance in low light conditions
    • No inverter shutdown because of under-voltage thresholds

Status Monitoring for Efficient Operation & Maintenance

  • Built-in status monitoring, allows string level operational statistics, fault alarms, remote monitoring and field management
  • Provides up-to-date status of operation for efficient maintenance assessments
  • Integrated wireless communications eliminates the need for extra cabling

Intelligent dust management system in three modes:

  1. Dust mitigation: During the night, the solar modules are set in a -15° downturn position to avoid night time dust settling on glass
  2. Dew mitigation: Night time stow position eliminates dew settling and therefore dust adhesion to the glass
  3. Auto Cleaning: Weather station detects rain events and system positions modules into optimum cleaning position
  4. Clean Mode: Positions the modules for easy cleaning. Allows operator to set modules in an upright position for fast & easy cleaning access
    1. Cleaning schedule: Periodic cleaning interval is based on local conditions, energy production degradation and cost to clean
