Wider range of applications

Solar power has always been a natural and renewable alternative energy source. It just needs to be captured and then converted.

The principles of PV have been known and utilised for some time in space applications and solar powered calculators. However, it is only recently that the industry has made real, rapid technological progress, making it possible for this energy source to become a viable alternative in a country's energy mix.

Photovoltaic energy is one of the answers to the energy challenges of the 21st century. The different panel and conversion technologies currently available make it possible to choose the most suitable solutions for each application. Regardless of the application – residential, building, solar park – SOCOMEC SOLAR will be able to give you advice, guaranteeing an optimum solution and efficient use of components.

The photovoltaic market is a

dynamic one, with promising

prospects in the years to come.

The growth of renewable energies

is an essential step towards

a sustainable energy policy.

A photovoltaic installation is a long

term investment that can bring

excellent returns, but specialist

skilled personnel must be used to

guarantee the best possible

efficiency, safety and duration. SIT

Residential application

An array of photovoltaic panels can be installed on the roof of a single dwelling or housing block.

A residential installation generally produces a peak power level of 2 to 6 kWp in the form of an alternating single-phase output voltage of 230 V.

Buildings Application

The external surfaces (roof, balcony, facade, etc.) of an industrial building, shopping centre or public building can be fitted with photovoltaic panels on areas ranging from a few square metres to several hundred square metres. This type of system produces a crest factor of up to 1 MWp. The power generated is injected into the low voltage (single or three-phase) or high voltage electricity grid (via a transformer cabin).

Solar parks application

Photovoltaic parks generally occupy large ground spaces and can accommodate sets of photovoltaic panels in areas covering thousands of square metres. These parks can produce high MWp crest factors. The equipment used to optimise the level of power injected into the grid is of considerable importance. The alternating voltage generated is generally injected into the electricity grid at medium or high voltage via a transformation station.

The photovoltaic market is growing

strongly and has high safety and

quality requirements. In a decade

it has gone from the experimental

stage to the industrial stage,

and now requires not only

professionalism but also the

standardisation of installation rules,

equipment, and start-up

procedures.

SOCOMEC's mastery of this

photovoltaic technology allows the

company to demonstrate its

commitment to striving for electrical

system optimisation solutions in

the context of environmental

conservation.

The safety of users and assets

The specific characteristics of these systems means that all possible measures must be taken to ensure system safety. This objective can only be achieved only if system components comply with national standards and rules of use are strictly adhered to.

At an electrical level a PV system has certain specific characteristics which must be taken into consideration, even if comparison in this sector is very limited compared to that of standard low voltage electrical systems, which have been around for more than a century.

System functionality

The set of components connecting the solar panel to the public electricity grid must be perfectly scaled and coordinated in order to provide optimum efficiency for the surface area of the modules used. This depends not only on the efficiency of the solar panels used but also on:

• the choice of system architecture,

• the dimensioning of cables and equipment,

• the performance of inverters,

• their Maximum Power Point (MPP) tracking system,

• the choice of voltages and types of LV/MV isolation transformers.

System reliability

In addition to contributing to the conservation of the environment, a photovoltaic system must also meet stringent reliability requirements.

If a fault occurs in any of the components power generation and the efficiency of the entire system are affected. To manage this efficiency there must be:

• a management and monitoring system,

• smart control of the inverters and maintenance and repair devices.

Inverters for photovoltaic installations on roofs with large surfacesThe external surfaces (roof, balcony, facade, etc.) of an industrial building, shopping centre or

public building can be fitted with photovoltaic panels on areas ranging from a few square metres to

hundreds of square metres. This type of system produces a crest power value of up to 1 MWp.

Downstream of the panels, the SOCOMEC solution covers:





The inverter, being a DC / AC conversion device, plays a crucial role in PV system performance.

Its performance characteristics must correspond to the specific requirements of the system.

Installations on roofs with a large surface area are more powerful than residential applications

and require additional functions. In particular, solar inverters must be connected to a centralised

management system if the installation is to operate with maximum efficiency.

The inverter is used in different ways, depending on the size of the installation and the choice of

architecture:

• PV strings connected in parallel to a centralised inverter,

• each PV string connected to its own inverter,

• the inverter is capable of managing different sets of strings (modular solution).

Inverters for solar parksPhotovoltaic parks generally occupy large ground areas and can accommodate sets of photovoltaic

panels covering thousands of square metres. These parks can produce high MWp crest factors.

High performance equipment is used to optimise the level of power injected into the grid. The power

produced is generally injected into the electricity grid at medium or high voltage via a transforming

substation.

Downstream of the panels, the SOCOMEC solution covers:





The inverter is a complex DC / AC conversion device and thus plays a crucial role in a PV system's

performance. As power generation in photovoltaic parks is subject to certain restrictions a number

of specific functions are required. In particular, solar inverters must be connected to a centralised

management system and their use and maintenance must be simplified.

When combined with the monitoring options and control panels of SUNSYS IFB strings,

SUNSYS solar park inverters are the optimum solution for maximising the output of the installation.

A photovoltaic system isn't just solar panels connected to an inverter. These 'vital organs' have to

be made complete with a set of protection devices in order to safeguard the generation system

against the unexpected.

SOCOMEC disconnection and protection solutions provide:

• safety during emergency intervention in the event of electric shock or fire, and during all

maintenance operations. SIRCO PV load-break switches ensure disconnection, switching off

in emergencies and switching off to allow firefighting access

• and the protection of assets, especially against solar panel inverse currents and overvoltages

generated by lightning. PV fuses and fuse basesprotect not only the panels against inverse

currents but also the PV generator strings against DC breakdown currents. SURGYS PV surge

protection devices protect the panels and inverters against overvoltages of atmospheric origin.

These switching and protection devices can either be housed in boxes or photovoltaic string

control cabinets (see Monitoring section), depending on the panel technology and the size of the

installation.

Equipment SURGYS PV surge arrestors

Photovoltaic panels and inverters account for a sizeable proportion of total investment.

The objective of a Class II device is to protect users from indirect contact with live parts. This also applies to the polarities of PV modules, as electric arcs in PV installations can be particularly destructive and protection against them is essential. Standard requirements on this put particular emphasis on the (Class II) physical separation of the + and – poles (unipolar PV cable). These requirements must be applied to the enclosures and switchboards where all strings and sets of strings are connected.

A photovoltaic installation has the characteristic of placing all the components of the enclosure under continuous stress, whereas in most other applications this stress is occasional, and this is in addition to the stresses of the ambient temperature and the direct exposure to the sun's rays. Theoretical simulation is not enough to guarantee the perfect management of heat increases or the unexpected tripping of overcurrent protection devices. Only laboratory testing in accordance with IEC 61 439 Standard procedures can give the right indications for guaranteeing the effective operation of the system.

Our combiner switchboards have been designed and tested as specified in the standards and guarantee compliance with all the requirements and specifications of these installations.

We can provide you with exactly the right solution for your installation, from a simple residential box to a multi-inverter enclosure with monitoring.

Technology Inverter technology

With over 40 years experience in the design and manufacture of uninterruptible power supply systems, SOCOMEC has always been at the cutting edge of technology in electrical power conversion.

SUNSYS inverters, made by SOCOMEC SOLAR, have benefited from the technological progress resulting from this knowledge. These innovative technologies increase the efficiency and lifetime of your installations.

Maximum power point tracking

SOCOMEC inverters use a maximum power point (MPP) tracking algorithm that ensures the maximum utilisation of the power supplied by the solar panels.

Our experience in the field has shown us that the MPPT can vary sharply in relation to the temperature and intensity of the sun's rays. That's why we've developed an algorithm that solves this problem and gives very good dynamic behaviour results.

This dynamic efficiency is certified by the Fraunhofer-Instituts für Solare Energiesysteme. These results make SOCOMEC SOLAR inverters the market benchmark.

Smart-Cooling technology

Cooling is a crucial element in the efficient operation and lifetime extension of an inverter. That's why we've developed a smart cooling system.

The fans are controlled and operated on demand, taking account of the input load and temperature, in order to optimise heat dissipation.

SUNSYS inverters are made with the use of 3-level inverter bridge topology, based on SOCOMEC's considerable experience in this field (10 years of research on UPS Green Power products).

This technology, an innovation in electrical power conversion applications, reduces the voltage between the IGBT terminals (power switches) by half.

The switching losses are thus reduced significantly.

This optimisation of the inverter bridge means thatSUNSYS inverters can achieve a conversion efficiency of over 98%.

Technology Inverter technology


Given the average annual solar radiation in Europe, photovoltaic stations have to work most of the time in reduced luminosity conditions. The efficiency of the inverter is thus essential, despite the poor meteorological conditions.

The SUNSYS inverter, with its modular architecture and DPC (Dynamic Power Control) function, maximises the efficiency of your system.

The inverter starts generating efficiently even when the solar radiation is very low.

• The best efficiency

The DPC optimises the efficiency of your installation in a particular way for partial loads. The inverter starts generating electricity from a low solar radiation level. The P03 inverter gives 96% efficiency with a load of just 5 %.

• Longer lifetime

Thanks to the DPC, only the modules actually needed for power generation operate. The power models are also operated cyclically to share the load time. The operating time of a module is thus optimised, and this lengthens the useful lifetime of the inverter.

• Better availability

If one of the inverter power modules stops (due to a breakdown), the system will reconfigure automatically in order to get the best use out of the remaining modules and continue supplying the maximum possible amount of power.

Their modularity allows them to maximise overall efficiency by using only the power modules that it needs. In poor solar radiation conditions, less modules are used, working with greater loads and therefore with greater efficiency.
