Inverter’s Significance
Inverters account for <10% of the system cost but,
Influence up to 20% of system cost
Manage 100% of system production
Are the “brains” of the system
Mitigate O&M expenses through PV asset
management solutions
Inverter selection is critical for the long
term financial performance of a PV system

Benefits of Floating PV Installations
21
Improved module performance
Reduced land usage
Easier installations
Environmentally friendly
Floating Systems – Selected Systems

Higher Lifetime Value with SolarEdge’s Floating Solution
23
Increase Revenue
Decrease Expenses
Mitigate Risk
More Energy by Reducing Mismatch
Module mismatch is unavoidable in floating PV installations
24
The weakest module reduces the
performance of all modules in the string
Each module produces maximum power
independently of other modules in the string
More Energy by Optimizing Bi-Facial Modules’ Advantages
Bi-facial modules are often used in floating installations, to benefit from water surface reflectivity
SolarEdge eliminates mismatch from shading on the backside of bi-facial modules, further
improving energy generation
25
Higher Lifetime Value with SolarEdge’s Floating Solution
26
Increase Revenue
Decrease Expenses
Mitigate Risk
BoS Cost Saving by Flexible Design
27
Up to 50% reduction
in BoS costUp to 60
modules
per string
Fewer strings
Less wiring, combiner
boxes, fuses, etc.
Less onsite self-crimping
at string end
Reduced risk
of failure & fire
Lower O&M Costs with Module-Level Monitoring
When operating on water, onsite monitoring and
maintenance must be optimized due to location
and access issues that might require approach
via a boat
SolarEdge’s module-level monitoring is free for
25 years and offers full control and visibility,
remote troubleshooting and cost saving
maintenance
28
Lower O&M Costs with Module-Level Monitoring
Full control and visibility
Module-level performance monitoring
Automatic alerts to identify module
and inverter underperformance
Complete system status on your mobile
device
Comprehensive reporting tools,
including one report for multiple
systems
29
Lower O&M Costs with Module-Level Monitoring
Remote troubleshooting
Pinpoint underperforming modules to their physical location, prior to sending a technician onsite
Easy detection of PID and burnt bypass diode
Remote module voltage measurement
30
Bypass diode failing
Good modules, with full voltage
Underperforming module, with reduced voltage
Lower O&M Costs with Module-Level Monitoring
Cost saving maintenance
Maintenance scheduling according to
problem severity
Pre-planning of site visit and required
tools and equipment
Remote management of service tasks
instead of onsite
31
Longer Warranties with SolarEdge
Inverters require at least one replacement during system lifetime
Funds need to be set aside to cover replacement costs
With SolarEdge:
Longer standard warranty of 12 years
20 year warranty expansion option
Lower-cost inverter replacement after warranty: ~40% less than traditional
inverters
32
Future Compatibility with SolarEdge
Simple module replacements and system expansion
No need to keep module stocks, any module
available in the market would fit
New power optimizers and modules can be utilized
in the same string with older models without
loosing energy due to mismatch
33
Higher Lifetime Value with SolarEdge’s Floating Solution
34
Increase Revenue
Decrease Expenses
Mitigate Risk
Safe Installation and Maintenance
Since floating PV installations are placed on water,
they are potentially more prone to safety hazards
SafeDC™ – no high VDC during installation or
maintenance
SolarEdge inverters comply with UL1699B arc
detection standard designed to mitigate effects
of some arc faults that may pose a risk of fire
35
