Turns PV Panel of any type into a source of peak power at a constant voltage
Up to 25% increase in harvested Solar Energy
Allows Parallel Operation for power build-up to hundreds of kilowatts
As Long a Life as the host PV Solar Panel
Innovation Patent granted in Australia in 2009; pending in other countries
MPPT with intelligent power conversion
IEC harvests maximum panel power flow even during its sub-optimal state
due to shade & soiling and prevents huge power loss
Simple to Install and Total Operator Safety
The most inexpensive solution for higher energy harvest
Useful in any solar power plant; from sub-kW to Megawatts
Enables use of energy efficient All Parallel Array
Most solar arrays are composed of "series strings" of matched panels, wired in series to have high
voltage DC and higher power. This conventional approach is fundamentally vulnerable - when
individual panels experience minor variations in output, Vp, they disrupt the output of the string and
the entire array, cutting overall energy harvest by 15 to 30 percent!
Independent studies prove that the highest energy loss in PV Solar Panel is when a shadow is cast by a
tree or dust, dirt, leaves or bird dropping that covers even in one PV panel within a series string of
several panels. (See the study by the Director of Renewable Energy at the National Semiconductor
Corp. USA)
MITRAMAX Energy’s Parallel Solar architecture addresses this inherent vulnerability. With the addition
of a simple V-Boost converter +MPPT in a PV module, each panel becomes a fully independent, highly
efficient contributor of power to the array - just like a power plant on a grid. That is what IEC does. We
have got Australia's Innovation Patent for this in 2009.
IEC's Parallel Array gives system designers flexibility regarding PV panel location, orientation and
overall system size. Installers have a safe, simple wiring scheme with easy expansion and per-panel
monitoring. And most importantly, system operators improve their expected output and payback.
