The SolarEdge System
Each panel is connected to a single power optimiser
Power optimisers are electronic chips that maximise energy from
each panel individually
An inverter converts DC to AC
Monitoring portal visualises performance of each panel

The Solution
2.
1.
1. Power Optimiser
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 panel
Constant feedback on the
performance of each panel
Automatic shutdown of each
panel for maximum safety in
case of emergency
3.
2. Inverter
3. Monitoring Portal
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 optimisers
Small and aesthetic
By displaying real-time
performance data, the
monitoring portal allows:
Full visibility of your system
performance
Automatic alerts on system
issues
Easy access from a
computer, smartphone, or
tablet

Up to 25% More Energy From Each Panel
MORE POWER
Reduced O&M
cost
Asset protection Enhanced safety
In a PV system each panel has an individual maximum power point
Traditional inverter – weakest panel reduces the performance of all
panels
SolarEdge – each panel produces the maximum energy.
̶ The weakest panel does not affect the performance of the rest of the system

What if I don’t have any shading?
MORE POWER
Reduced O&M
cost
Asset protection Enhanced safety
In a traditional system, any kind of mismatch between panels introduces
power losses. SolarEdge power optimisers eliminate these power losses

Uneven Panel Aging
MORE POWER
Reduced O&M
cost
Asset protection Enhanced safety
Panel performance
degrades 20% over 20 years
However, each panel will
age at a different rate
SolarEdge – each panel is
producing the maximum
energy without affecting
the performance of other
panels

Third party report by LHW Partnership compared power
optimiser & string inverter power conversion performance
A total of 20 system scenarios were constructed in PVSyst for
SolarEdge and string inverter
Domestic 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”

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

ASSET PROTECTION
Enhanced safety
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 string
Expansion: new power optimisers can be utilised in the same
string with older models
Low-cost inverter replacement after warranty
– 40% less than traditional inverters

Asset protection ENHANCED SAFETY
PV systems are safe and pose no
danger to people and property
However, 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

Asset protection ENHANCED SAFETY
With SolarEdge whenever AC power
is off, DC wires are designed to
automatically de-energised
SolarEdge power optimisers are
designed to automatically shut down
the DC voltage in the PV wires to
protect installers, maintenance
personnel and firefighters
SolarEdge meets the most advanced
European safety standards
Safe DC

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.
