1.1.Introduction
The Egyptian Association for Energy and Environment (EAEE) is implementing a
projectfundedbytheEuropeanUnion-ENPICBCMED-crossbordercooperationat
theMediterranean, titled"DevelopingandImplementingDecentralizedInnovative
Solar Energy Technologies in Public Building (DIDSOLIT-PB) " where as the
projectaimsto:
 Transferup-to-date- solarenergyusestechnologies
 Transform the governorate's public buildings into energy saving buildings
through the installation of developed solar systems that generate energy of
totalcapacityof79.2Kwtobeusedinlightingandair-conditioning
 Providetechnicalsupportandcreatenewexpertiseinthefieldofsolarenergy
technology.
ThegrowingconcernfortheuseofrenewableenergiesandthereductionofCO2
emissions of the society has led the Public Administrations to promote Projects
regardingalternativeenergysources.
Photovoltaic solar energy presents itself as a clean and environmentally friendly
alternative.Inaddition,ithastheadvantage,duetoitsmorphology,ofbeingeasily
integrated in urban environments, where most of the demand and energetic
consumptionisconcentrated.

1.3.1 Self-Consumption
The rate of self-consumption refers to the share of solar energy that is used
directly in the home or indirectly through intermediate storage. The higher the
self-consumption rate, the better it is for the PV system’s ideal operational
conditions.
Since the feed-in compensation for solar power is clearly less than the typical
householdelectricitytariff,itmakessensetouseasmuchsolarenergyaspossible
foryourselfandfeedaslittleaspossibleintotheutilitygrid.Thismakesyouless
dependent on energy suppliers and rising electricity prices. The intermediate
storage of PV power increases the self-consumption rate by creating a reserve
supplyofsolarpowerforuseintheeveningandatnight.

Energy and Environment (EAEE)
1.3.2.Self-ConsumptionwithZeroInjectiontotheGrid
In certain applications, it is forbidden to feed electrical generation back into the
grid.Thisisusuallyimposedbynationalregulationsandlegislationand,asofthis
writing, it is the situation in Greece and Spain. Additionally, in some other
countriesthereis“feedin”legislationlimitingthepercentageofgeneratedpower
thatcanbefedintothegrid,forexampleinGermany70%oftheinvertersmaximal
power is allowed to be injected in the grid at the coupling point, or 60% of
maximalpowercanbe injectedbytheuseofabattery-supportedsystem.Itismost
likelythatthis“feed-inlimitation”willbeadoptedbyothercountriesaswell.
Marketresearchshowsthatwhile“feed-inlimitation”orinverterpowercontrolis

arerequiredtohaveanti-islandingprotection.
For this project, the inverter application is the second one, without
photovoltaicgridinjection.

GeneralDescriptionoftheSystems
The use of photovoltaic solar energy is through the direct and immediate
transformation of the radiation from the sun into electrical energy using the
"photovoltaic effect". This transformation is carried out in the so-called "solar
cells" that are made from semiconductor material, mostly silicon. When sunlight
strikes the cell, photons transmit their energy to electrons of semiconductor
material that jump in the pool, thus generating an electric current capable of
driving an external circuit. Photovoltaic modules are composed of photovoltaic
cellselectricallyjoinedtogether.
PV modules produce DC energy which has to be transformed to AC current, in
orderto be consumed orevacuated to thepublic grid.Themaximum powerthat
cansupplyamoduleinstandardconditionsiscalledpeakpower(Wp).However,
thefinalenergyperformanceratiowillbedeterminedbythePVsystemdesignand
theenvironmentalandlocationoutputs.
Photovoltaic energy is characterized by being clean, long lasting, requiring lowmaintenance,offeringhighreliability,andisenvironmentalfriendly.

4 System’s Components
4.1.Photovoltaicmodule
PV modules convert solar energy into electrical energy. They consists of solar
panels and these, in turn, are composed of several identical interconnected cells
electrically in series and/or in parallel,so that thevoltageandcurrent suppliedby
the panel isincreasedand adjustedtothedesired value.
Most of the solar panels are constructed first by combining cells in series to
achievethe desiredvoltagelevel,andthen bycombining parallel multiple numbers
of cells toachievethe desiredcurrentlevel associations. Inaddition,the panel has
other elements of solar cells, which enable adequate protection set to external
agents for ensuring sufficient rigidity, the clamping to the supporting structures
andthe electricalconnection.
Amongallthepossibletechnologies,DIDSOLIT-PBprojecthasfocuseditsresearch
andimplementationinthreedifferenttechnologiesforbuildingintegration:
 SemitransparentSilicon(approx.35%transparency)
 Semitransparentthinfilm,a-Si(10-20%transparency)
 Flexiblethinfilm,a-Si(opaque)

EventhoughnowadaystheCrystallinetechnologyisabsolutelydominantinthePV
market, due to its high efficiencies and production costs reductions, thin film
technologies, specifically the integrated ones, have also been taken into
considerationduetotheirintegrationpotential.

The extra costs of Building-integrated PV modules (BIPV) might be compensated
bytheirreplacingotherconventionalproducts(roofing,facadesandcanopies)and
byprovidingsomeofthesameconventionalproperties,suchas:
 Watertightness (façade,roof,skylight,pergola)
Thewatertightness comesnotonlyfromtheglassproperties,butespeciallyfrom
themountingsystemthatintegratesit.
-Semitransparentsurfaces:PVglasslaminatedlayer
-Opaquesurfaces:StandardPVmodules:glasslaminated,glass+tedlar,EFTE.
 Thermalinsulation(façade,roof,skylight)
In most of the climates, building envelope glazing units have to 26ulfil certain
insulation requirements. Glass laminated PV modules can be part of insulated
glazingunitsthatperforminthesamewaythatastandardglazeshould.
 Sun protection (façade, roof, skylight, pergola –roof / ground mounted-car
sherter)
- Semitransparent surface: (glazed surface: semi transparency-solar factor;
shading devices:brise-soleils,canopies,pergolas,etc)
Solar modules can be opaque or semitransparent. In mono- or polycrystalline
modules,thespacingbetweencellsandtotheedgecanbemodifiedsoastoallow
variation of shadowing and transparency. In thin-film modules, additional cuts
perpendicular to the cell strips create a semitransparent effect. Because
semitransparentmodulesabsorblesslight,theyarelessefficientperunitofarea.
Therefore,performancediminisheswithincreasingtranslucency.
Main technical parameters to be checked, depending on the project
requirements:
 Constructionrequirements:thermalinsulation,semi-transparency
 Size
Depending on the project requirements, a certain degree of dimensional
flexibilitymightberequired.Standarddimensionsmightnotbesuitableinsome

Thin film modules production process has strict rules regarding standard
dimensions.
Crystallinelaminatedmoduleshavemuchmoreflexibility.
 Glasscompositionandthickness

PVB lamination foils have been traditionally the only ones accepted for BIPV in
Europe,forsafetyreasons(elasticitycoefficient).
Glassthicknessrangesfrom4+4to6+6,dependingonglassdimensionsandstatic

ef iciency ranges between 12% and 20%. It is the most common technology,
representingabout90%ofthecurrentmarket.

Crystallinelaminatedmoduleshavemuchmoreflexibility.
Globaldimensionswilldependonthelaminationcapacityoftheproviderandthe
modularity of the cells: Starting from 480 x 1475 mm; 720 x 1600 mm; 850 x
1650 mm; 1200 x 1800 mm, are typical optimized dimensions. However, the
maximum available dimensions will depend on the glass lamination capacity of
themanufacturer:1600x2600mm;2100x3100mm;etc.
 Glasscompositionandthickness
The substructure system, its position in the building (façade, roof, etc) and
modulationwilldeterminethestaticloadsandglasscompositionrequirements.
A glass laminator and/or PV module provider should provide advice about the
mostsuitablesolutionineachcase.
PVB lamination foils have been traditionally the only ones accepted for BIPV in
Europe,forsafetyreasons(elasticitycoefficient).
Glassthicknessrangesfrom4+4to6+6,dependingonglassdimensionsandstatic

 Transparency
The PV module’s transparency depends on the sun protection and natural
lightingrequirements.
The distance between cells (about 1-2-4-6 cm, depending on the ribbons
direction)willdeterminethePVmoduletransparency(10-40%).
Thestandardtransparency,whichisabout35%,leadstoinstalledpowerratiosof
approximately90-100Wp/m2.
Opaquecrystallinemodulescanincreasesignificantlytheinstalledpowerratios,
till140-180Wp/m2,dependingonthetechnology.
 Junctionbox
Crystalline laminated modules can easily adapt both back and lateral junction
boxes.
Lateral junction box might be a good solution to hide all the cabling and
connections inside the secondary substructure, such as aluminum or steel
profilesandcaps.

4.1.2GlasslaminatedThinFilmtechnology
Thin film modules are constructed by depositing extremely thin layers of
photosensitive materials onto a low-cost backing such as glass, stainless steel or
plastic.
ThinFilmmanufacturingprocessesresultinlowerproduction costscomparedto
the more material-intensive crystalline technology, a price advantage which is
counterbalancedbyloweref iciencyrates(from5%to13%).However,thisisan
averagevalueandallThinFilmtechnologiesdonothavethesameefficiency.
Four types of thin film modules (depending on the active material used) are
commerciallyavailableatthemoment:
-
Amorphoussilicon(a-Si)(5-7%)
Egyptian Association for
Energy and Environment (EAEE)
-
Cadmiumtelluride(CdTe)(9-10%)
CopperIndium/galliumDiselenide/disulphide(CIS,CIGS)(10-13%)
Multijunctioncells(a-Si/m-Si)
AlthoughCdTe,CIS,CIGSmodulesmightreachhigherefficiencythana-Siones,
siliconhastheadvantageofbeingeasilyavailableinnature.
Thin film have better temperature coefficient, reduction in power output at
highertemperatures,thancrystallinemodules.
Thin-film materials have better out-put in weak light than silicon modules.
However,theglobalperformancewon’tsolelydependonthematerial,butalso
ontheharmonizationoftherestofthePVmodulecharacteristics.
Laminatedglassmodules-technicalparameters:
 Constructionrequirements:thermalinsulation,semi-transparency
 Size
Depending on the project requirements, a certain degree of dimensional
flexibilitymightberequired.Standarddimensionsmightnotbesuitableinsome
cases.
Thin film modules production process has strict rules regarding standard
dimensions.
Themanufactureprocessofthethinfilmmodulesislinkedtoacertainstandard
dimensions:
RigidCISandCdTestandardmodulesareusually available insetdimensionsof
600 x 1200. A-Si modules have a wider range of possible dimensions, although
600x1200mm;1100x1300mmarethemostcommon.
The combination of these sub-modules and the subsequent lamination process
enlarges the range of possibilities: 600 x 1200mm; 1245 x 635mm; 1242 x
1245mm;2462x635mm;1849x1245mm.
 Glasscompositionandthickness
The substructure system, its position in the building (façade, roof, etc) and
modulationwilldeterminethestaticloadsandglasscompositionrequirements.

Aglasslaminatorand/orPVmoduleprovidershouldprovideadviceregardsthe
mostsuitablesolutionineachcase.
PVB lamination foils have been traditionally the only ones accepted for BIPV in
Europe,forsafetyreasons(elasticitycoefficient).
Thin film modules have a particularity that comes from its production process:
thea-Sifilmlayerisdepositedonaglasssub-base(3.2mm loatglass).Inorder
toobtainthesamecharacteristicsofa5+5mmPVBlaminatedglass,dependingon
the dimensions, sometimes it is required a composition of 6T+3.2+6T (T:
temperedglass).
Thismakesglassdimensionalflexibilitymoredifficultandcostly.
 Transparency
The PV module’s transparency depends on the sun protection and natural
lightingrequirements.
Thetransparencyisgivenbythepatterncutmadetotheinitialdeposition.
The resultant “microcells” allow a good visual transparency, even though the
global PV module transparency percentage ranges are quite similar to the
crystallineones(10-30%).
The standard transparency of 10% leads to installed power ratios of
approximately44Wp/m2.
Opaquethinfilmmodulescansignificantlyincreasetheinstalledpowerratios,till
66-110Wp/m2,dependingonthetechnology.
 Junctionbox
Simple laminated thinfilmmodules(not insulated ones)usually integratesmall
junctionboxes(two:oneforeachpole)inordertosimplifythemoduleinternal
electricalinterconnection.
WhenthePVmodulerequiresglasslaminationatbothsides,thelateraljunction

Basedonasimilarproductionprocesstothinfilmcells,whentheactivematerialis
deposited in a thin plastic, the cell can be flexible. This opens the range of
applications, especially for Building integration (roofs-tiles) and end-consumer
applications.

Thin-film materials have better out-put in weak light than silicon modules.
However,theglobalperformancewon’tsolelydependonthematerial,butalsoon

For example, the plastic encapsulant roughness might increase the out-put loses
duetothedirtaccumulation.

a system (for example a system's installed power or several solar field
orientations),thereisawidevarietyofcommercialinverterssuitableforallkinds
ofeverypossiblescenarios.
There are countless photovoltaic installations worldwide and many companies
developing solar inverters around the world. To limit the options in this study,
two major European companies are selected: SMA Solar Technology AG (SMA)
and Fronius, both global leaders in the development, production and sales of
solarinverters.
Twofactorsaretakenunderconsideration:
- the(sub)system'sinstalledpower(2.5kW,5kW,10kW,15kWand20kW)
- thesolararrayorientation
Important aspects for investors to take into consideration when choosing an
Inverter:
- It must have a high efficiency, as otherwise it will unnecessarily increase the
numberof panelstopower the load
- Itmustbeprotectedagainst shortcircuitsandoverloads
- Addrearmament and automatic disconnection
- Snapshot support higherpower demands 150% of your maximumpower
- It must comply with the requirements laid down in Regulation Low Voltage.

To carry out an estimation of energy production, it is necessary - apart from the
characteristics of photovoltaic glazing - to take into consideration the following
information:
 Orientation: corresponding to the orientation of the photovoltaic surface
respecttotheSouth.
 Inclination: angle that corresponds to the surface of the module and
photovoltaicglassandthehorizontalplane.
 Shadows: shadow effects felt by the orientation of the facade, where the
valueisrepresentedin%.
 Installed power: real power is installed, calculated from the maximum
outputofpeakpowerofthesumofallthesolarpanelsthatcomposeit.
 System loses: includes all the components, with special attention to the
cablevoltagedrop.
Theconceptsdefinedintheenergyestimationarethese:
 PVpowermodules:thesumtotalofindividualpowermodulesizinginthe

 Power Inverter: the inverter rated power necessary to optimize the
performanceoftheinstallation.Thispowerratingisusuallybetween8and
14%lessthanthePVpowermodules.
 Annual energy produced: the result of expected annual energy obtained
fromtheinstallationlocationconditions,slope,orientation,powercapacity
andsystemefficiencyestimates.
 RatiokWh/kWp:representsthetotalnumberofhoursofplantoperation

MONITORINGSYSTEM
TheMonitoringsystemforPVinstallationshould readtheparameters;PVproductionof
three different fields: Façade, Roof and Skylight; CO2 avoided; energy consumption of
electrical loadconnected; power qualitysupplied to the load; grid power quality; export
importcapacity;and,thetotalenergyconsumptiononthebuilding.
Theparameterscanbeshownviainternetanditisrequiredthedatacanbedisplayedto
thepublicbyascreen,too.Itshouldincludeallnecessarymaterialsforinstallation(RS485
wire,software,computer,protections,etc.).
Twocomputersareneededfortheconnection,oneforthelocalconnectionandtheother
for theSCADAcentraldatabase.
Both computers have to be connected to the same grid, and have connection to the
internet. The entire system works with web pages, so the information can be retrieved
fromanycomputerhavinganInternetorintranetconnection.
Thedifferentsituationswehavetohandlearethefollowing:
1. Internalconnection
Internal connection of the "second screen" and clients on the LAN to handle this, we
havetoconfigureastaticIPaddressforthemonitoringsystem,anduseitontheclients,
oruseDHCPandbesurethatthemachinenamewillbecorrectlyupdatedontheDNS,
sowecanusethenameforaccessing.
2. Externalaccess
Onceagain,wehavetwochoices:FixatingastaticIPaddressandopeninganincoming
port (80 if possible), and having a ixed IP address or a DynDNS name for the WAN
connection,or,wecanusetheremoteviewsystemofCircutor,toputthesystemonline,
for this purpose, we'll need the outgoing connections to port 22 to be granted on or
firewall,ifany.
Becarefulaboutthesecondoption:CircutorserverislocatedinGermany,sothedata

3. Remoteaccess
Themonitoringneedsremoteaccesstobothcomputersinordertoconfigurethem,do
the tests and for maintenance. For that the system use VNC, and once again we can
redirect some ports to the VNC of the computers, or use the remote view system. A
static IPaddress canconnect to global datacenter with a route for each photovoltaic
installation.

This is ideal for those buildings with electricity consumption in daylight hours. The
equipment, the CDP family (Dynamic Power Control), adjusts the power output of
photovoltaic inverters to what is being consumed at all times. In this way, we ensure a
zeroinjectionnetwork.
Features: Zero injection to the network without energy dissipation or electromechanical
switching of dynamic power control of solar Photovoltaic modules investors by shifting

ofparticularimportance.
The previous research conducted in the project has led to the Technical Team’s
selectionoffourpublicbuildingsforcarryingoutthePVinstallation,asdescribed
intheattachedExecutiveProject.
The uncertainty of the regulatory framework in the photovoltaic field, especially
regards consumption, lead us to a zero injection to the Grid solution, despite it
being designedto be able to interact with theGridinthefuture iftheregulatory
frameworkbecomesfavourable.
The object of the contract to be performed, as defined in this Technical
Specification,isthefollowing:
LOT 1) The supply of PV modules for architectonic integration (different
technologies), which are necessary to execute the four photovoltaic installations
detailedherein.
LOT 2) The execution, installation, commissioning and legalization of four
projectswithintegratedphotovoltaicsystemsforselfconsumptionandinjectionto
theGrid.
Regards the integrated photovoltaic technologies (BIPV), the Technical Team of
the DIDSOLIT-PB project has already developed a "benchmark" of the main
components (PV modules and inverters), which has helped them to develop the
technicalandglobaleconomicproposal,aswellasthebindingExecutiveProjects
scheduleandTechnicalSpecifications.

1.3.3.1Solarmodules
A photovoltaic module exposed to daylight produces electricity. It is always
necessaryto considerthePVelements(modules,moduleseries,branches)under
power,eveniftheDCand ACswitchesareopen.
The Solar Modules generate DC electricity whenever sunlight shines on the solar
cells.
•Solarmodulesshouldbemountedfirmlyontothestructure
•Potentiallylethalvoltagescanbedevelopedfromarrays.Therefore,theModules
should beshadedfromsunbyopaquesheeting,beforeanyelectricalconnections
aremadeto themodules
Whileworkingonthefacade,disconnectthemodulesfromthebuilding'selectrical
installation withthemainpowerswitch.
Neverdisconnectorconnectthemoduleswithoutfirstopeningthecircuit.
Switchoffordisconnecttheloadbeforemodifyingthebranchconnectionsonthe
modules under power. Photovoltaic systems are considered to be low voltage
systems.
However, the system's maximum voltage is generally very high. The in-series
connection of the modules will add each module's voltages; the total voltage will
exceedthesafetythresholdof 120VDCrelatedtothelowvoltage,butshouldnot
begreaterthantheinputvoltageofthe inverters.ForSUNEALphotovoltaicblade,
thismaximumvoltageis ixedat600VDC(even thoughthecomponent'scertified

1.3.3.3Grounding&lightning
Lightning is one of the most awesome phenomena of nature and produces both
electricand magneticfieldswhichvarywithdistance,frequencyandtime.Dueto
theadvantagesoflow maintenanceandautonomousoperation,solarpowerarrays
aresituatedinmanydiverse, isolatedandextremelocationsthroughouttheworld.
Protection against a direct lightning strike should only be necessary for critical
applications or where the probability of a lightning strike is high. In general
effective grounding of solar array structures and associated equipment will give
adequateprotectioninthefield.

asmentionedintheinstallation/usermanual.
GroundingthesolarPVsystemisimportantforbothsafetyandprotectionagainst
lightning. Groundingtheequipmentensuresthatthesystemvoltagecannotdrift

groundingalsoprovidesapath forfaultcurrentsinducedbylightning.

Tomakethesolarpowersystemassafeandsecureaspossible,allexposedmetal
(e.g. solar array structure, charge Controller / panel enclosure, metal cable
conduits etc.) should be grounded. Use super grounding kits for grounding
purposesifitisrecommendedintheproduct /system.
Electrical grounding leakage on stationary battery installations can lead to low
temperature carbonization fires. This can happen with valve regulated batteries.
Ground leakage can also arise due to physically leaking cells or block batteries
because of damaged housings or due to leakage through the valve , especially in
caseofhorizontalinstallations.
Ground leakage is possible, for instance with earthed racks or battery
compartments or where these are in direct ground contact. Over time, acid

1.3.4.3Insurance.
It is perceptive during the building construction that the liable technicians have
professional indemnity insurance. However, the contractor has to have the
required professional indemnity insurance to cover its industrial activity. This
insurance should cover the inherent risk of its activity towards third parties of
which the contractor could be liable outside the contract, by its own fault or
negligence,orthepeopleheisliablefor.Itisunderstoodthatthisprofessional
