M+W Solar
Over the last ten years the M+W Group
supported the growth of the PV community
with sustainable facility concepts and
executed more than 9.3 GW of turnkey
projects for companies such as First Solar,
Q-Cells and REC.
Based on that knowledge the M+W Solar
GmbH was founded in September 2010 to
supply the down stream market with ? rst
class EPC services.
As an independent EPC contractor as well
as in cooperation with PV system partners
the company has supplied and realized
solar power plants with a total capacity of
around 40 MWp in the ? rst two years.
The wide range of competencies and the
huge experience across the complete value
chain in the photovoltaic sector quali? ed
the M+W Solar GmbH as a reliable business
partner for engineering, procurement and
construction (EPC).
M+W Solar is able to support you any-
where in the world thanks to the global
footprint and our extensive range of
services and long-term experience.

Optimized power output – single MPP tracking for each string
Intelligent Grid Inverter Concept
M+W Solar’s optimized and cost effective inverter concept
The M+W Solar’s central inverter concept sets new capacity and ? exibility standards in the construction of large-scale PV power plants. M+W Solar offers two types of central inverters: MW 125 (maximum PV power 140 kWp) and MW 230 (maximum PV power 250 kWp).
Due to the string connection box with single string MPP tracker, it is possible to connect varying amounts of PV modules and different slopes and orientations for each string. The new concept also allows the usage of different PV module technolo-gies without negative mismatch effects. The single MPP tracking reduces the negative effects of dust, module shading or aging mismatch. Due to the optimized DC to DC conversion on the string level the M+W Solar inverter concept reduces the power losses because of the higher voltage ? xed level.
M+W Solar’s inverter concept for
large-scale PV power plants
The modular M+W Solar’s inverter concept is suitable for PV systems ranging from 100 kWp to well above 10 MWp. It com-bines high technology with intelligent single string MPP trackers to offer a solution for complex PV large scale power plant demands. All single PV module strings can be tracked through the web-based string monitoring system worldwide. This system provides greater visibility at the string level, it allows to interact with the power plant and identify faults and losses in the system very fast.
The advantages are:
? Single MPP tracking for each string ? No mismatches ? DSP processor ? Less DC-loss
? Intelligent and modular components ? High ef ? ciency at low power ? 250/550 kg in weight
? Web-based string monitoring system
