  1. Renewable Energy Initiatives Solar PV Deployment – Dr. Rajan Kapur • Residential – Mostly roof mounted. Fixed and few BIPV • Upto 10kW, up to 1000 sq-ft. • Si, and recently CdTe • $8/W installed • Commercial – Mostly roof and flat roof mounted. Fixed and few BIPV • Upto 1MW. approx 100,000 sq-ft • c-Si, CdTe, CIGS tubular • $7/watt installed • Utility Scale – Ground mounted. Fixed and Tracking • Largest approved by PG&E 550MW (for 2012, @ $2/W quoted) • Tens of acres up-to tens of square miles! • C-Si, CdTe, CIGS flat plate • One report of $3.17/watt installed • 15.5MW Nellis AFB, 12 MW Boulder City, 8MW Alamosa ..

  4. Benefits of AC PV Modules • Simpler Field Installation • MicroInverter is attached to the PV module in the factory • System design is simplified: Scalability • Increased AC Power Harvest • Increased Robustness – Longer Unattended Operation • Remote monitoring of individual components • Single failure does not affect others in the array More Value-Add in the Factory Less Assembly Work in the Field 5% to 20% more AC Power Harvest Larankelo Inc.
