2 Petra S olar created and leads the market for complete, integrated S olar, S mart Grid and Grid Availability solutions Smart Solar market and technology leader SunWave, the world s only pole-attached, integrated Smart Grid and distributed solar generation system Tested and verified by utilities and in volume production E ngaged with over 50 utilities world-wide USA, USN, USMC and USAF installations Solves critical pain points in enormous market Actively developing the solar and Smart Grid market in regions around the world World class management team Veterans of utility, solar, semiconductors & communications industries Extensive utility management and operations experience Municipal, state and federal energy policy and regulation expertise Funded by US Army s Venture Capital Investment fund Managed by OnPoint Capital for US Government 2

3 World s Firs t Pole-Mounted S olar Utility C ontract $200 million contract with one of the nation s leading utilities 200,000 SunWave systems to be deployed throughout New Jersey 40-megawatt virtual power plant distributed across the state 90,000 units already installed World s largest distributed solar deployment 3

4 Challenges Military Bases are Facing Providing energy security & independence Alleviate outages Reduce potential hacker attacks Renewable fuel = independence Reducing dependence on foreign oil Provides a secure, renewable indigenous fuel source Mitigating rapidly increasing costs of energy sources Estimated that the US military spends $20 billion on fuel each year Eliminates transportation and delivery costs Electricity costs are increasing, while PV generated electricity costs are decreasing Meeting federal mandates Cut energy use by over 25% by 2025 Creating and preserving jobs Reducing casualty risks Transport of fuel via truck convoy represents risks For every 29 fuel convoys in Afghanistan, one soldier/sailor s life is lost 4

5 Solution: Distributed Solar PV Micro-Grid utilizing SMART grid functionality with energy storage Enhanced Energy Independence and Security Independence from the utility grid Eliminates extensive peak electricity charges Leverage existing assets/lower start-up costs Can be installed on utility and streetlight poles, rooftops, parking structures with local DC charges, etc. Smart Grid renewable deployment Reduced local distribution losses Increased reliability Lower Operation and Maintenance (O&M) costs No single point of failure Reduced fuel consumption Incremental deployment and immediate commission Repurposing Enables the tear-down and reuse of the Solar units on alternative sites Increased energy efficiency and harvesting Maximum Power Point Tracking (MPPT) per panel 5

6 SunWave Technology Smart Energy PV Module that incorporates a panel level inverter, grid sensors, and secure wireless communications to transmit grid data and establish a Smart Grid network Pole-mount and rooftop-mount systems offer enhanced grid reliability and monitoring of critical grid and production data Secure web portal provides user with access to revenue grade meter incorporated into each Smart Energy Module Directly tied to low-voltage secondary grid; energy is used by the load or returned to the utility in the form of energy savings Smooth energy management between different distributed resources, i.e., PV, energy storage, grid connection, diesel 6
