BUILDING THE LARGEST SOLAR SMART ARRAY IN NORTH AMERICA: Behind the Scenes of a 2.2 MW Solar Power Plant
•
1 j'aime•715 vues
Go behind the scenes of the development and construction of the recently commissioned 2.2 MW solar power plant constructed by Talmage Solar Engineering, Inc. in Sharon, Vermont. This is the largest solar "smart array" in North America, and was featured prominently in the industry press and at SPI 2012. The system combines Upsolar modules backed by Upsolar's reinforced warranty Tigo Energy's PV solar power optimizers and digital monitoring, and Solectria Renewables inverters, to feed optimized renewable energy directly into the local grid. Project developer Talmage Engineering's CFO Kale Inoue will review the project's history and will lead a panel discussion with and Upsolar's Troy Dalbey, Tigo's Paul Grana, and Solectria's Brad Sherman . The panel will review the challenges faced in developing the project and the technical advances that allow the system to perform at a lower cost per kilowatt hour than a traditional array. You will learn what it takes to get a project of this size from concept to electricity production, hear from vendors of key system components about their design, and see how everything is performing since commissioning in July 2012.

- 12. SunGen Sharon1: 2 MW Smart Array Project location: Sharon, VT Total Power: 2.2 MW Technology: Terrafix Solarpark Developer: Talmage Solar Module: UP-M230P Optimized by Tigo Type of Project: Vermont FIT - Utility 12
- 13. Why a Smart Array @ SunGen Sharon? Talmage SE decided to pursue an Optimized Solution for their SunGen Sharon1 project because a PV array on such hilly terrain would leave modules configured on a different plane within the same strings; reducing the output of the PV power plant; therefore reducing the IRR’s of the project. The Smart Array Solution provided by Upsolar & Tigo Energy maximizes the performance and provides Talmage SE the flexibility they needed to develop a profitable project on terrain that would otherwise not be suitable for PV Development .
- 14. Benefits: Upsolar Smart Module Smart Module Benefits: - Maximizes energy output - Increased design flexibility - Eliminates module mismatch within strings - Voltage control reduces BOS costs; increasing # modules per string by up to 25% - Module-based performance monitoring streamlines cost of diagnosing O&M issues - Electronic theft prevention protects your investment - NEC Article 690.11 Compliant Cost Impact / Adder: - UP-M240P - $0.10/Watt - UP-M290P - $0.08/Watt
- 15. Module Level Performance Monitoring
- 16. Key Benefits: Tigo Optimized Array Incremental Cost of Module: + $0.08 - $0.10/Wp Smart-Curve™ $0.05/Wp reduction in electrical BOS costs • More modules on any roof ($0.05 – $0.10/Wp) • Increased Energy Harvest ($0.05 – $0.08/Wp) • BEW certification for bankability of The Solar Model (Pvsyst competitor) pending • Reduced O&M costs ($0.02 – $0.03/Wp) $0.10 to $0.15+/WP of net economic value! • Increased inverter rated power output (5 – 8 cents/Wp; available mid 2013) • Monitoring system cost (including MMU & gateways) is competitive with Draker, Deck, ERI, etc. 19
