Why24/7 Solar
Monitoring Matters
Power Generation is a 24/7 Business
• All Steam Electric Stations operate 24/7• All Wind Farms operate 24/7
• The Electric Grid is operating 24/7• All Utilities operate 24/7
Solar Farms = Power Plants
• It is true that PV cells only operate in daylight hours
• The Balance of Plant Equipment Operates 24/7• DC Collection System• Inverters• Medium Voltage Transformers• Substation Equipment
o Breakerso Relayso Main Power Transformers
24/7 Control Centers
• Promotes Safety• Identify Issues in Real Time• Remote Reset of Critical Equipment • Dispatch Resources in a Timely Manner• Communicate with Utility and Grid Operators• Ensure Maximum Production is Available at
Sunrise

Current Status of Monitoring – MORE!
• Leads to more monitoring:• Global PV Monitoring Deployments Outpace PV Plant
Installations in 2013 • Driven by new installations and retrofits, the PV
monitoring market grew by more than 90 percent between 2012 and 2013.

GW of new installations. Source: GTM Research/SoliChamba Consulting
Global PV Monitoring Technologies, Markets, and Leading Players, 2014 – 2018
• More GW, more plants, even more plants per investor:
• PV Is getting more geographically distributed. 79 countries with policy targets for renewables in 2008, 138 in 2012.
• Secondary market is active -> investors are acquiring / enhancing their portfolios rapidly. 187MW of plant have been sold in Italy in the secondary market.

Investor Challenges
• Plant Level:
• Underperforming PV Plants
• Poorly planned and executed preventive maintenance
• Poorly engineered and delayed corrective maintenance
• Security more challenging than expected
Italy Biaxial Install – Alectris
Investor Challenges
• Portfolio Level – O&M:
• More GW, more plants, even more plants per investor
• Geographically dispersed assets
• Incongruent original plant monitoring systems
• Lack of integrated approach to global fleet management
• Simple tasks to be managed for large fleet of PV Plants in
several countries lead to dramatic operational complexitySource: Solar Power World, Solar OM Tools for the Solar Investor, June 28, 2014
Georgia Power 1 MWp – Alectris
Investor Challenges
• Portfolio Level – Asset Management:
• Lack of transparency into operations and financial
reports for the funding partner
• No standard method for keeping financial or operational
records
• Cash flows and margins under continuous pressure

Gru.Co Italy 4MWp – Alectris
Investor Challenges
• Policy Level:
• Fluctuating incentive, legal and fiscal environment
• Lack of standardized processes and procedures
• FiT schemes abandoned (Spain, Greece, Italy cuts,
Romania GC revision..)
• Several market close to grid parity or close to be
bankable PPA markets (Italy, Chile, US..)
Georgia Power – Alectris
Investor Challenges
• Margin Protection:
• Fluctuating incentive landscape puts increased pressure
on margin protection
• Missing important deadlines can pose a potential risk to
the investment
• Inefficient management can substantially increase the
costs

• A full Asset Management and O&M
package requires more than 96 single
(simple) tasks to be performed
(excluding accounting)
• Example: A 40 PV plant
geographically distributed portfolio
result will result in
40x96=3840 tasks!!!
Scaling requires evolved and
suitable
tools and an efficient
organization
Investor Challenges
THE PV MARKET PROMISES
...a PV Plant is a Financial Investment...
THE PV MARKET REALITY
...a PV Plant is an Industrial
Investment!
Evolution of Fleet Level Monitoring
THE REAL NEED
• An industrial investment must rely on an
evolved and fully integrated Business
Management Software (commonly known as
an ERP(*)) that:
• Facilitates information flow between all
the business functions
• Shares data across various locations or
fleets
• Manages connections to all the outside
stakeholders
Evolution of Fleet Level Monitoring
(*) ERP: Enterprise Resource Planning
REDEFINING MONITORING…
…Instead of monitoring the outcome (measured produced
energy) monitoring and managing the operations (technical and
financial asset management) that lead to the outcome……TO THE ERP EVOLUTION
...Simple monitoring must evolve towards full
Solar ERP Systems allowing full Fleet Level Management
and Operational Monitoring
Evolution of Fleet Level Monitoring
Solar ERP Systems for Fleet Level Management
• Provide the best possible insights on the PV asset
operations through:• World class monitoring system
• Service management
• Asset management
• Integrated management of multiple and geographically distributed
PV plants
• Extensive and customizable reporting capabilities
Evolution of Fleet Level Monitoring

• Intelligent Monitoring – Industry Trends
• Presented by:o Keith Davis – Director of Solar Serviceso Affinity Automationo Charlotte, NC 28269
• Intelligent Monitoring – Industry Trends• Trend # 1: Technical Standards are
Changing:o (This trend will drive the remaining four trends discussed
today)
• Industry and utility standards will change to allow increased inverter:o Functionalityo Regulationo Controllability
• UL1547A will be the interim step to allow more inverter functionality and the need for even more monitoring and control capability
• Intelligent Monitoring – Industry Trends• Trend # 2:
o Solar monitoring will grow and change into Solar Control and Monitoring
• Bi-directional – A two way street into the PV systemo Inverterso Combinerso Protection Systemso Utility Interconnection
• SCADA system will be expected and eventually required by the utilities to allow them system control and regulation
• Intelligent Monitoring – Industry Trends• Trend # 2 (cont.)• The use of remote inverter control will become permissible
and expected in large scale commercial/utility PV systemso IEEE1547A will soon permit inverter control on “non-utility”
owned plants to provide:
• Voltage and Frequency Ride Through• Voltage Regulation• Curtailment• Power Control – PF and VAR support
• California is leading the industry by helping to accelerate the adoption of IEEE1547A and other new standards being developed
• Intelligent Monitoring – Industry Trends• Trend # 3
o More PV system hardware will be connected and monitored than ever before – Anything with a microprocessor will be connected!
• Site communications requirements will take a quantum leap forward in the near future
• And reliable, robust and high bandwidth communications hardware will absolutely be required
• Ethernet will become the protocol of choice for most systems
• But good old Modbus will still be included in the mix• And utilities are going to expect a new protocol – DNP3• It’s all about the data stream out and commands coming
in
• Intelligent Monitoring – Industry Trends• Trend # 4
o Big data becomes part of the solar monitoring equation• With the increase in monitored points, the amount of
data flowing from the system will increase…exponentially!
• How to deal with that flood of information will require some new software tools:o Data Mining – Looking for the needle in the haystacko Analytics – Determining system parameterso Reporting – What is the system doing and what does
it needo This data can be very helpful for solar O&M providers and system
owners to determine needed services and expected revenues if accurate and timely
• Intelligent Monitoring – Industry Trends• Trend # 5
o Utilities will demand “ownership” of the system inverter(s) and require SCADA systems be included in every project
• When the inverter becomes a utility asset, then they have full rights to be able to regulate and control the system to suit their Grid requirements
• To set energy, power factor, voltage and other generational parameters
• No longer will the amount of grid delivered energy be the only metric to determine system profitability…but there will have to be a sea change in how the owner is compensated for the energy the site can deliver to the inverter
• Intelligent Monitoring – Industry Trends• A Recap
o Trend # 1: Standards are changing creating new opportunities
o Trend # 2: Remote system control become the norm within PV monitoring systems
o Trend # 3: More BOS hardware connected and monitored than ever before requiring robust data networks
o Trend # 4: Big data will be generated on all sites and will need to be mined and analyzed for accurate and timely information
o Trend # 5: Utilities will become inverter “owners” and control the energy delivery to and from the grid to suit their needs
• Intelligent Monitoring – Industry Trends• Conclusions:
• It’s a brave new world in the solar monitoring
industry! • Be prepared to take advantage of the new
opportunities that will come and come soon.• Doing nothing is NOT a viable option, so learn all
you can about these five trends to support your customers, enhance your business and increase profitability.
