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

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
![Page 25: Optimize Your Floating PV System with Module Level Power ... Julia Serebro_Floating ENG KOREA - March 2019 - Share.pdf10 Omron RANK COMPANY SolarEdge 2 SMA Ginlong 4 Goodwe 5 Omron](https://reader030.vdocuments.us/reader030/viewer/2022040811/5e535eed4ddc4d5006434589/html5/thumbnails/25.jpg)
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

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

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
