Making Solar Simple
USPV Overview
• Founded in 2008 with the goal of Making Solar Simple for PV owners via
turn-key SREC management
• Historically focused on Maryland, DC and Pennsylvania solar market but
now active in various REC markets across PJM
• Clients include municipalities, blue-chips, home owners and everything
in-between
• Competitive advantage
– Understanding of the market place and a track-record of delivering
excellent customer results. 97% customer retention rate
– Collaboration with developers, installers & IPPs to get projects built
– DE-MAP software yields automation and scalability

How The Grid Works
• Reduce kWhs
• Generate kWhs
• Reduce kW demand
charge

Behind The
Meter In Front Of The
Meter • Whole sale energy
• Capacity
• Ancillary services
• Reserve
• Regulation
Straddling The
Meter • Renewable Energy
Credits
• Demand Response
Next-generation solar projects – that include storage and dispatch
capable inverter - will further blur the line regarding what DG assets
can do
Software As The “Killer App”
• A Distributed Energy Resources Management System (DERMS) is
middleware software solution that sits between Distributed Energy
Resources (DERs) and the grid to which they connect
November 23, 2014 USPV Confidential & Proprietary 14
• EPRI’s Integrating Smart Distributed Energy
Resources with Distributed Management System,
does a good job describing the need for a DERMS
• The same DE-MAP software that USPV uses to
manage RECs is being expanded to provide turn-
key management of more complex solar projects
• Aggregation
• Real-time economic dispatch
• Customer reporting and payment

Safer Installations
SafeDC™: Optimizers and dc cables drop to 1 Vdc if inverter is off
Array is de-energized to <30 Vdc
No high Vdc during installation, maintenance or firefighting.

PV Safety: 2014 NEC
Operating Voltage Rising: 600V to 1000V
PV voltages climb When OFF (Voc)
PV voltages climb When cold (water)
Rapid Shutdown Introduces the idea of Service Voltage
Control mechanism required at the array: <30 Volts within 10 seconds
Draft 2017 NEC: extends reach of rapid shutdown to within the array

PV Intelligence
Inverter is “Brains of PV Array”
Inverter is now growing a nervous system
Extending to modules:
Integrated monitoring: eyes and ears
Increased flexibility: using PV in more places
Increased energy: high resolution harvesting
Increased safety: able to de-energize
Extending to Grid:
Reactive to grid saturation
Dispatch power to home; storage; grid
Help regulate grid voltage and frequency
