22.5 MegaWattBlock: Welcome to the Future of Solar Technology. With the 2.5 MegaWattBlock, BELECTRIC is

setting new standards in solar power produc-

tion. On a par with the functionality of large

conventional power plants, our grid-stabiliz-

ing power plant technology makes it possible

to intelligently integrate renewable energy

sources in existing power grids. This means

that grid expansion due to Renewable Energies

could be kept to a bare minimum.

The 2.5 MegaWattBlock is a high-performance

power plant unit, which forms a ground-

mounted solar power plant, either indepen-

dently or in combination. This standardized

modular design is founded on many years of

experience in the realization of power plants

around the world. Precisely tailored to the

area and customers requirements, the 2.5

MegaWattBlock stands for an optimum cost-

benefit ratio and safeguards your investment

in the long run.

With a performance ratio of up to 85%,

the perfectly tailored system design of the

2.5 MegaWattBlock offers above-average

system efficiency. The performance ratio is

viewed as a meaningful quality indicator in

photovoltaics and defines the overall efficiency

of a system. The higher the value, the lower

the losses through conductors, inverters,

and electrical components. The new

power plant unit is ready to operate with

a maximum system voltage of 1,500VDC.

With this higher voltage it is possible to

further reduce system and maintenance

costs. In addition to system efficiency, the

2.5 MegaWattBlock also sets new standards

in terms of reliability. The inverters of the

Power Condition Unit achieve a staggering

availability rate of over 99% controlled by the

BELECTRIC Realtime Management System.

These success factors are the result of years

of research and development in the field

of photovoltaics one of the best types of

power generation for the climate and the

environment. An integral part of BELECTRICs

vision has always been to produce solar

electricity at a lower price than oil and gas

(based on world market prices). With the

2.5 MegaWattBlock, this goal has become

reality across all climate conditions. The

intelligent power plant technology and the

standardized system design make it possible.

London nEW YoRK: This very distance of more than

5,600 kilometres would be the result if we line up all the

photovoltaic modules that we have installed worldwide in 2011.

System Design: The Components of Success.

Our success lies in the system. All components

are optimally tailored to their functions. The

2.5 MegaWattBlock is a consistent power

plant unit developed for the construction

of solar power plants in 2.5 MWp steps. The

BELECTRIC system design is characterized

by its intelligent combination of high-quality

components. Specially developed materials

ensure decades of reliable operation, even in

extreme environmental conditions.

The block design of the successful BELECTRIC

product series sets new standards: with its

help, it is possible to reduce the levelized costs

of electricity even further.

The advanced Power Conditioning Unit (PCU)

with built-in reactive power control ability

helps to improve the stability of the local grid

network. Compared to traditional reactive

power control devices, the PCU is designed to

provide reactive power to the full extent of its

rated power and to react dynamically to grid

voltage deviations - with a power loss lower

than 1%. Also the fact that the reactive power

control works even without sunlight is a benefit

of the BELECTRIC power plant technology.

Optimize the economic viability of your

investment in solar energy with the new

2.5 MegaWattBlock.

SubstructureThe laser-precise linear alignment of the substructure has made it

possible for each photovoltaic module to receive the same

exposure to light. Standardized components manufactured

from high-quality raw materials in heavy industrial-grade

and series production. The installation is high-precision

and machine-assisted. The substructure is always

optimized to the local environmental conditions and

static load requirements.

Module technologyBELECTRIC consistently promotes photovoltaic modules with modern

thin-film technology. These comply with the newest state-of-the-art

technologies, ensure optimal use of solar irradiation and require significantly

fewer raw materials during production than traditional silicon-based

technologies. So within the first year of operation, they generate more

energy than was required to produce the modules. The 2.5 MegaWattBlock

may also be equipped with other module technologies, upon

customers request.

power Conditioning unit (pCu)

The specially developed Power Conditioning Unit (PCU) in-

cludes an intelligent inverter system with up to 1500VDC system

voltage and a transformer station. The inverter system is

optimized for the use of thin-film module technologies

and is characterized by the high level of system

efficiency. The built-in PID protection device

reduces the module degradation effect.

A typical public grid shows many volt-

age deviations produced by different

power loads. The dynamic reactive

power capability of the PCU stabilizes

the public grid voltage - day and night.

The PCU with its medium-voltage grid

supply in outdoor construction en-

ables optimum accessibility and easy

maintenance of the system.

power plant Controller (ppC)

The intelligent control unit monitors the grid access points and

regulates the electrical current flow of the solar power plant and

adjusts the voltage using reactive power. Specially developed volt-

age sensors and software algorithms detect emerging grid require-

ments and react automatically. Reliable support for the local grid.

With the Real-time Management system all grid access points and

solar power plant data are permanently available to

be monitored. The web interface offers a

huge variety of logging and analyzing

tools. With the extensive analysis

and logging functions, you al-

ways have data on the solar

power plant output with all

its parameters at hand. This

basic data makes it possible

to avoid system failures and

to increase operating safety.

New Technology: For a Stable Power Grid.

The existing power grid was originally designed

as a distribution grid: large power plants

produce power centrally at high and highest

voltage levels for consumers at a lower voltage

level. This concept endured unchanged for

almost 100 years. However, the installation of

renewable energy sources over the past decade

has brought about the addition of energy

generators at low and medium voltage level. The

result: a significantly more complex, distributed

grid structure. With the 2.5 MegaWattBlock,

BELECTRIC provides the electricity suppliers

with an essential component for sustainably

stabilizing the power grids. The solution is

an intelligent control unit that can be used to

smoothly integrate the new product range into

the worldwide power grids and to combine

them with conventional power plants. Thus,

this new technology contributes significantly

to the improvement of the grid stability

for operators and consumers, establishes

photovoltaics as decisive part of the energy mix,

and makes the costly extension of the power

grids redundant.

Depending on the corresponding country-specific

specifications, the voltage in the public power grids

must be maintained in a voltage corridor so that

electrical loads are not damaged. Furthermore,

fluctuations should be minimized in order to allow for

smooth operation. The reasons for voltage deviations

are fluctuating feed-in of renewable energies and

unforeseeable consumer loads.

Grid stabilization by means of reactive power control

The reactive power is an electrotechnical variable

caused by a phase shift of the current intensity

regarding the electrical voltage. The reactive power

occurs everywhere in the power grid, is a necessary

element for the current flow, and has a significant

influence on the grid voltage. BELECTRIC uses this

effect and is able to reduce the share of reactive power

in the power grid on the one hand, and to increase

the aforementioned deliberately on the other hand.

This intervention results in the option of changing

the mains voltage as required and with low electrical

loss ( 0 (inductive)

to cos > 0 (capacitive).

The reactive power control unit can be either run in

automatic mode (within the power utility companies

parameters regarding the local grid requirements)

or in semi-automatic mode accessible by an active

external control signal.
