I detta arbete undersöks solceller som integrerat fasadmaterial och hur det påverkaren rad olika faktorer. Som utgångspunkt i arbetet jämförs en solcellsfasad med entraditionell träpanel. Syftet med arbetet är att utreda lönsamheten av integreradesolceller i fasaden, både ur ekonomisk, miljömässig och byggteknisk synvinkel.Anledningen till valet av ämne grundas på den låga utbredningen av solenergi iSverige i förhållande till den potential som finns. Fasadintegrering sker främst påstörre byggnader i Sverige vilket medför en nyfikenhet hur integrering på en mindreyta påverkar lönsamheten. Med hänsyn till ovannämnda tankar har det valts attundersöka en enplansvilla placerad i Karlstad.Genomförandet av arbetet sker i form av ett antal moment. Till att börja med ritas tvåkonstruktionsritningar med hjälp av Revit. Därefter kontrolleras det om solceller somfasadmaterial klarar de BBR-krav som finns samt att en jämförelse mellan de olikasolcellstyperna görs. Vidare ritas byggnaden och dess omgivning upp som en3D-modell i Revit och en solstudie görs som sedan används till hjälp vid upprättandeav en LCC-kalkyl. Solstudien används även för att bestämma solcellernas orientering.LCC-kalkylen visar slutligen vilken av solcellerna som är mest ekonomiskt lönsam vidtre olika ekonomiska förhållanden. Till sist sammanställdes information omkoldioxidutsläppen för båda fasadmaterialen.Efter sammanställning av ovan nämnda genomförda moment kunde det konstaterasatt solceller som integrerat fasadmaterial inte påverkas mer av Boverkets krav änandra fasadmaterial. Solcellernas orientering var i detta fall på fasaderna i väster,söder och öster. LCC-kalkylens resultat visar att solcellen Trina Solar 400 W har lägsttotalkostnad vid normala ekonomiska förhållanden. Solcellen är av monokristallintyp. Koldioxidutsläppen för monokristallina solcellers livscykel uppskattas till cirka58,1 g CO2/producerad kWh. För produktion av den valda träpanelen uppskattaskoldioxidutsläppen till cirka 3,4 kg CO2/m2. De totala koldioxidutsläppen för solcellerav monokristallin struktur beräknas till 63 kg CO2/m2 för den totala driftsperioden på25 år.Solceller som integrerat fasadmaterial är olika ekonomiskt lönsamt beroende på hurinflationen, räntan samt prisstegringen varierar. Med dagens värden ärmonokristallina solceller både miljömässigt och ekonomiskt lönsamt samt att deklarar de krav som ställs från Boverket. Det konstateras att solcellerna genererar denenergi som krävs vid tillverkning, drift och transport av dem inom cirka två till tre år,vilket inte träpanelen har möjlighet att göra. / In this work, photovoltaics are investigated as an integrated facade material and howit affects a number of different factors. As a starting point in the work, a photovoltaicfacade is compared with a traditional wooden panel. The purpose of the work is toinvestigate the profitability of integrated photovoltaics in the facade, from aneconomic, environmental and construction point of view. The reason for choosingthis subject is based on the low distribution of solar energy in Sweden in relation tothe potential. Facade integration in Sweden is most often applied to larger buildings,which leads to a curiosity about how integration on a smaller area affects theprofitability. With regard to the above-mentioned thoughts, it has been chosen toinvestigate a single-storey villa located in Karlstad.The implementation of the work takes place in the form of a number of steps. Tobegin with, two construction drawings are drawn in Revit. Then it is checked whetherphotovoltaics as a facade material meet the requirements set by Boverket and acomparison is made between the different photovoltaic types. Furthermore, thebuilding and its surroundings are drawn as a 3D model in Revit and a sunlight studyis done which is then used to help create a LCC calculation. The solar study is alsoused to determine the orientation of the photovoltaics. Finally, the LCC calculationshows which of the photovoltaics is the most economically profitable under threedifferent economic conditions. Finally, information was compiled on carbon dioxideemissions for both facade materials and the total profitability of the selectedphotovoltaic.After compiling the above-mentioned completed steps, it could be stated thatphotovoltaics as integrated facade material are not affected more by the requirementsset by Boverket than any other facade material. The orientation of the photovoltaicsin this case was on the facades to the west, south and east. The results of the LCCcalculation show that the photovoltaic Trina Solar 400 W has the lowest total price.The photovoltaic is of monocrystalline structure. The carbon dioxide emissions forthe life cycle of monocrystalline photovoltaics are estimated at approximately 58.1 gCO2/kWh produced energy. For the production of the selected wood panel, carbondioxide emissions are estimated at approximately 3.4 kg CO2/m2. The total carbondioxide emissions for monocrystalline photovoltaics are estimated at 63 kg CO2/m2for the total operating period of 25 years.The economic profitability of the photovoltaics is depending on how the inflation,interest rate and price increase varies. With today's values, monocrystallinephotovoltaics are both environmentally and economically profitable and they alsomeet the requirements set by Boverket. It can be stated that the photovoltaicsgenerate the energy required to manufacture, operate and transport them withinabout two to three years, which the wood panel is not able to do.

In line with the expansion of the building industry, future projects like buildings and infrastructure require high demands on energy issues. EU directives and major global goals constantly set guidelines for what should be done and not. Construction and architecture companies in Sweden can influence what future cities will look like. This requires knowledge in these issues, not least about solar cell facades. Solar panels are mostly applied to roofs and big fields directed upwards towards the sun, but could one imagine solar cells integrated or applied to the facade of a building? This is what this thesis is about, and how the market looks today for these technologies in 2019. Therefore, the purpose is to compare solar cell technologies and attachment possibilities on facades of buildings. The goal is to give architects insight into how they are and can be used for future facade solutions. Most of the work has consisted of literature studies from books, reports research and the internet. The results turned out to be that the techniques are under a maturing phase after intensive research has been made in the field of solar cells, as well as increased use, lower prices and more efficient techniques. Today, it is possible to utilize solar cell facades in Sweden and other countries around the world. The sun is a renewable energy source that can cover the majority of the world's energy and electricity needs.
