> SMA studied the concept 20+ years ago
> But reliability never met company standards
> All concepts (to date!) show higher failures
> Concept was shelved as „not mature“
> Recent developments gave a new spin
> Market focused on features over reliability
> Technology allowed radical component reduction and integration
> Strict quality controls
> US and Europe Manufacturing
> Advanced Software support
> SMA embraced the micro-inverter concept and developed a product line around it

AC MODULE: WHAT IT IS / IS NOT
NEC defines AC Modules in two places:
• Article 690.2: an AC Modules is a “complete, environmentally protected unit consisting of solar cells, optics inverter and other components, exclusive of tracker, designed to generate AC power when exposed to sunlight”
• Article 690.6: defines the electrical output of an AC module and their specific installation requirements
• An AC Module is tested and certified by an NRTL (UL, CSA, etc) as a complete assembly; the inverter is factory-integrated with the module; and the entire unit carries one end-to-end warranty from the module manufacturer
• Standalone microinverters are tested separately, installed separately, and warranted separately from the PV module

2011 CONFIDENTIAL | 4
AC MODULES VS STANDALONE MICROINVERTERS
AC Modules must meet stringent UL-1703 standards:
• Integrated module must pass resistance tests before and after TC-200
• Integrated module must pass resistance tests before and after HF-10
• Cables / connectors must pass the ‘steel ball test’
Environmental requirements • Same as PV module, +85C backsheet temperature
Integrated inverters are developed jointly with PV module vendors
• Must provide compatible warranty (25 years of power production)
• Very stringent reliability requirements

BENEFITS OF SOLARBRIDGE-ENABLED AC MODULES
UNPRECEDENTED RELIABILITY
• 0.1% annual FIT rate
• No inverter replacements over life of system
INCREASED ENERGY HARVEST
• Distributed MPPT mitigates effects of shade, mismatch, soiling
• Increased system uptime – no single point of failure
LOWEST INSTALLATION AND OPERATING COSTS
• Module and inverter are fully-integrated at the factory
• Lowest time and cost of installation

LABOR SAVINGS ON THE ROOF
2012 CONFIDENTIAL | 13
AC modules offer significant and proven labor savings for installers over stand-alone microinverter systems.
In a refereed time trial on identical roofs, a system with 20 standalone microinverters required 75% more time to install than a SolarBridge ACPV system. This difference is attributed to the additional time required on an stand-alone microinverter system for:
• Installing and securing the trunk and drop cabling
• Installing and securing the standalone microinverters to the racking
• Installing and securing the GEC
• Connecting and securing the DC cables from each microinverter
2011 CONFIDENTIAL | 14
THE RESULTS
AC Modules (SolarBridge) Install Time – 0:58 hrs
DC Modules + Standalone Install Time – 1:42 hrs
2011 CONFIDENTIAL | 15
INSTALLATION COST ADVANTAGE: AC MODULES vs STANDALONE MICROINVERTERS
1. Factory-installed inverter
2. Factory-installed cabling
3. Factory-installed EGC
4. GEC is eliminated
Modules simply plug together
Cost Penalty for Standalone – $945 Cost Penalty – $0.17 per Watt
