Module Mismatch
Each module in a PV system requires different current andvoltage to operate at Maximum Power Point (MPP)Modules with different MPP -> module mismatch
SolarEdge Monitoring Portal: Lighter shades of blue signifies stronger power output

Traditional InverterMPPT per entire stringAll modules receive the same current,regardless of their individual MPP

Thermal Mismatch
IR-camera reveals:Temperature decreases by 13°C from top tobottom row of modules in this PV plant = 5.6%Pmpp mismatch
(∆Pmpp=13°C * 0.43 [%/°C])
Module Mismatch
Tolerance Mismatch
Thermal Mismatch
Power MismatchFrom the manufacturing plant,the warranted output powerrange of modules may varygreatly. A standard deviation of+/-3% is sufficient to result in~2% energy loss.
Wind and shading betweenmodules in a large system cancause significant temperaturevariances.

Module Mismatch
Soiling and Partial ShadingModule soiling, from dirt, birddroppings, or snow, contributesto mismatch between modulesand strings
While there may be noobstructions during site design,during a system’s lifetime, a treemay grow or a man-madestructure may be erected thatcreates uneven shading.

Module Mismatch
Uneven AgingMost modules age to an acceptable degree of <80% of their nameplate outputBut the different rate at which they age introduces aging mismatch

Improved Bottom LineMore Modules
| 17©2014 SolarEdge
More Modules By Design
Power optimisers enable installation of: Modules in partially shaded areas Strings of uneven lengths Strings in multiple orientations and different roof facets
More modules on the roof
More power & Revenue Traditional inverter: 149.5 kW DC SolarEdge: 200 kW DCIncrease 34%
| 18©2014 SolarEdge
More Modules By Limitation
Very cost effective Feed-in Limitation deviceWorks for any size systemFail-safe in case of damaged communication cablesFast operationRetro-fit current clamps (split-core)
Example: 30kWsystem with21kW export limit

Improved Bottom LineReduced BoS Cost
| 20©2014 SolarEdge
SolarEdge Fixed String Voltage
String voltage is always fixed,regardless of temperatureand of string length
Constraint-free design Longer strings
Reduces wiring & BoS components
Flexible design formaximum roof utilization:
Parallel strings of unequal lengthsModules on multiple roof facetsModules with different power ratings
String voltage is always optimal for DC/AC conversion
| 21©2014 SolarEdge
Simpler System Design
Typical String Inverter SolarEdge
Limited string length 26-60 modules per string (up to 11.25kW)
Must match string lengths per MPP tracker Uneven strings can work in parallel
Shaded modules affect the entire string Only shaded modules are effected
Cannot mix different types of modules Any module size or type can be used
Locked in to same orientation/tilt per MPPtracker Any orientation/tilt

Case Study - Maximum Design Flexibility
String length can be 45/46 modules (compared to 21 with stringinverter), and stretch over 2/3 roof facets The whole system can be installed with 3 strings only –
one per inverter Significant BoS cost reduction

Example: PID Detection
Potential induced degradation is a physical phenomenareducing the modules power by reducing its fill factor and itsoutput voltageThe PID Effect is the strongest on modules closest to theinverter’s negative poleIf PID is suspected, technicians are required to climb on theroof, disconnect the modules, and measure their output voltage
