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. Egyptian Association for 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.

Solar inverters have special functions adapted for use with photovoltaic arrays, includingmaximumpowerpointtracking andanti-islanding protection. It is important for this project that the inverter communicates with the CDP (Control)orasimilarone,toactivateorde-activatethephotovoltaicstringswith theaimofzerogridinjection. Egyptian Association for Energy and Environment (EAEE) 1.3.4.Classification Solarinvertersmaybeclassifiedintothreebroadtypes: Stand-aloneinverters:theseareusedinisolatedsystemswheretheinverter drawsitsDCenergyfrombatterieschargedbyphotovoltaicrays.Manystandalone inverters also incorporate integral battery chargers to replenish the batteryfromanAC source,whenavailable.Normally,thesedonotinterfacein any way with the utility grid, and as such, are not required to have antiislandingprotection. Grid-tieinverters:thesematchphase withautility-suppliedsinewave.Gridtie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages. Batterybackupinverters:thesearespecialinverterswhicharedesignedto draw energy from a battery; to manage the battery charge via an onboard charger; and, to export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage, and arerequiredtohaveanti-islandingprotection. For this project, the inverter application is the second one, without photovoltaicgridinjection. 1.3.5.Protections(Antiislandingprotection) Intheeventofapowerfailureonthegrid,itisgenerallyrequiredthatanygrid-tie inverters attachedtothegridturnoffforashortperiodoftime.Thispreventsthe invertersfromcontinuingtofeedpowerintosmallsectionsofthegrid,knownas "islands".Poweredislandspresentarisktoworkerswhomayexpecttheareatobe unpowered.Equallyimportantisthefactthatwithoutagridsignaltosynchronize to, the power output of the inverters may exceed the tolerances required by the customer’sequipmentconnectedwithintheisland.

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.

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.

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.

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.

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.

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.

SUPPORTSYSTEMDESCRIPTION The support system solution is part of the architectural design, fulfilling the technical and the aesthetics requirements. All three integrations follow the same principle: substitute one kind of material necessary for construction with another that is not only capable of achieving the same conditionsastheoriginalone,butcanalsoproduceenergy. Theframe isincharge ofholdingthe solarpanel.Itoften willcomeina kit,inmodules,forproper assembly and installation. In case no kit is provided, the installation must be done in accordance withexistingregulations,whiletakinginto account the windstrength amongotherfactors. The structuremust withstand one windspeedsofatleastupto150km/h.Thisstructure is tobe determinedby theinclinationofthe solarpanels. 5.1 Considerationstoanalyze 5.1.1Snowloads As a reference for the dimensioning of the systems, we have considered different criteria actions fromtheEuroCode1(ActionsinStructures),whichcontemplatesobjectivevaluesforthecountries inthe European Mediterranean Basin. These values can beextrapolated, atleast, tothoseAfrican countrieswithEuropeantradition(Morocco,Algeria,TunisiaandLibya). To be able to generate an applicable design in any of the above-mentioned zones, the average valuesfromtheavailablereferencesofthecoastzoneshavebeenconsidered.

SYSTEMMAINTENANCE Maintaining a photovoltaic installation is scarce. This is practically reduced to cleaning modules,reviewconnections and securityfeatures. In somesituationsit may benecessary todisconnect thenetwork,whichwouldtherefore resultinsmall losses. Toensurehigh productivityoftheplantitis essentially reduced downtimes caused by a system failure or malfunction. For this reason,a good supervision system is neededbytheuser,offeringgood ServiceAssistance. Standardmaintenanceoperation Periodiccleaningofthemodulesshouldbedoneonceayear.Payattentiontotheinverter (Leds,status indicators and alarms) indifferent sunlightconditions, as thisis oneof the least reliable parts of the system’s equipment. Maintain control of the electrical connectionsandwiringmodules.Carryoutvisualinspectionofthemodulestoverifyglass breakage,moisturepenetrationinsidethemodule,andconnectionfailuresintheeventof breakdown. Other issues of operational maintenance include background checking electrical protectionelementsforpersonalsafetyandtheoperationofthefacility.Ingeneral,revise allequipment,wiring,connectionsandsupportstructures. 71 Egyptian Association for Energy and Environment (EAEE) The objective of maintenance is to prolong the life of the system, and to ensure good performanceandproductivityoftheplant,especiallywhereinstallationsconnectedtothe gridofferbackfinancialrewardsofenergyproduction. Planningstandardmaintenanceoperation I. USE AND SPECIFICATIONS - Shouldbekeptwithinacceptablelimitsoperatingconditions,performance, protectionanddurabilityoftheinstallation. - Should be replaced with items worn by use, to ensure the system works properlyduringtheirlifetime. - Should be observed main operating parameters (voltage and power) to verifythecorrectoperationoftheinstallation.

ENERGY STUDY To estimate power generation as realistically as possible in the simulation, it is necessarytoscheduleandusesunlighttointegrateallsystemlosses.Forthis,we usethesoftwareversionPVSyst,developedbytheUniversityofGeneva.This one ofthemostrecognizedsoftwareinthefieldandtakesintoaccountthemethodof calculationdescribedabove(seecalculationdetailsinannexes). Forthe study, we carriedout a simulation usingPVSyst,whichtook into account sizeanddataanalysis forthecompletePVsystem,andwasreproducedinsimilar conditionsastheprojects. 72 Egyptian Association for Energy and Environment (EAEE) 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.

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 protectionclassIIallowsamaximumvoltageof1000VDC). 5 1.3.3.2Controlelectronics Controlelectronicsisnecessarytomonitorandforpropersequencingofvarious system operationssothatthesolarenergyisutilizedefficiently.Readthe instructionsdescribedinthe relevantproductmanualthoroughlybeforeinstalling orworkingwiththeproduct.

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. Usethelightningprotectioncomponentsasrecommendedandinstallat appropriateplaces asmentionedintheinstallation/usermanual. GroundingthesolarPVsystemisimportantforbothsafetyandprotectionagainst lightning. Groundingtheequipmentensuresthatthesystemvoltagecannotdrift awayfromground potentialandthusreducestheriskofelectricshocks.Adequate groundingalsoprovidesapath forfaultcurrentsinducedbylightning. 6 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.
