The SolarEdge System
Each panel is connected to a single power optimiserPower optimisers are electronic chips that maximise energy from each panel individuallyAn inverter converts DC to ACMonitoring portal visualises performance of each panel

The Solution
By connecting a SolarEdge power optimiser to a PV panel it becomes a smart panel. This allows:
Harvest of up to 25% more energy from each panelConstant feedback on the performance of each panelAutomatic shutdown of each panel for maximum safety in case of emergency
The SolarEdge inverter is simpler and more reliable:
Responsible only for DC to AC conversion, as all other functions are handled separately for each panel by the power optimisersSmall and aesthetic
By displaying real-time performance data, the monitoring portal allows:
Full visibility of your system performanceAutomatic alerts on system issuesEasy access from a computer, smartphone, or tablet

Why SolarEdge?
ENHANCED SAFETYASSET PROTECTIONREDUCED O&M COSTMORE POWER
| 9©SolarEdge
Up to 25% More Energy From Each Panel
In a PV system each panel has an individual maximum power pointTraditional inverter – weakest panel reduces the performance of all panels SolarEdge – each panel produces the maximum energy. ̶G The weakest panel does not affect the performance of the rest of the system

What if I don’t have any shading?

Leaves
Snow Bird droppings
In a traditional system, any kind of mismatch between panels introduces power losses. SolarEdge power optimisers eliminate these power losses

Uneven Panel Aging
Panel performance degrades 20% over 20 yearsHowever, each panel will age at a different rate SolarEdge – each panel is producing the maximum energy without affecting the performance of other panels

Added Energy – In All Scenarios
Third party report by LHW Partnership compared power optimiser & string inverter power conversion performanceA total of 20 system scenarios were constructed in PVSyst for SolarEdge and string inverterDomestic and commercial scenarios were tested in different azimuths, roof angles and shading levels (ranging from none to high)“On each and every occasion the yield and performance ratio for systems utilising Solaredge inverters and optimisers exceeded those of the string inverters”

Added Energy – In All Scenarios
First year results - in all domestic scenarios and simulations undertaken the system yields and performance ratio were consistently higher for systems utilising SolarEdge ̶GRanging from 1.8% added yield in non-shaded scenario to 4% in
heavy shade

Future Compatibility
Account for future costs that can impact the return on investment during system lifetime
Replacement: SolarEdge power optimisers allow modules of different power classes and brands in the same stringExpansion: new power optimisers can be utilised in the same string with older models Low-cost inverter replacement after warranty– 40% less than traditional inverters

PV Safety
PV systems are safe and pose no danger to people and propertyHowever, as long as the sun is up, PV wires are energised with high DC voltages With traditional inverter, there is no option to shut down the high voltage on the roof

SolarEdge – Enhanced Safety
With SolarEdge whenever AC power is off, DC wires are designed to automatically de-energisedSolarEdge power optimisers are designed to automatically shut down the DC voltage in the PV wires to protect installers, maintenance personnel and firefightersSolarEdge meets the most advanced European safety standards
Safe DC voltage
The SolarEdge Safety feature is certified to IEC 60947 as a disconnection means between a PV inverter and a PV generator, and to VDE 2100 for safety in cases of firefighting or maintenance.
