För att beräkna hur stor effekt man kan installera på taket behöver man veta solpanelens area samt effekt. I detta fall har vi valt monokristallin kisel från Eon och den har en teknisk och ekonomisk livslängd på 30 år. Bilagan på sidan 37 och 38 visar solcellsprodukten.

Nedan visas en tabell på elektriska egenskaper hos modulen.

Tabell 2: Visar elektriska egenskaper av monokristallin solcellsmodul vid STC

Maximum Power (Pmax) 365 W

Optimum Operating Voltage (Vmp) 34,1 V

Optimum operating current (Imp) 10,71 A

Open Circuit Voltage (Voc) 40,7 V

Short Circuit Current (Isc) 11,42 A

Module Efficiency 20,0 %

Operating Module Temperature -40 °C to +85 °C

Maximum System Voltage 1000V DC

Modulen har en mått på 1,756m * 1.039m och arean blir då 1,824 m2. För att veta antal

paneler som får plats på taket dividerar man takets area med modulens area. 𝐴𝑛𝑡𝑎𝑙 𝑚𝑜𝑑𝑢𝑙𝑒𝑟 =./0123 242/5/ /61/789:;<=> ?@<? = C,AEBAB ≈ 46

För att kunna beräkna effekten på varje tak räknas det på följande sätt.

- Garage:

Antal moduler som monteras på garaget = I4JK51L3 /61/G/6/H123 /61/= C.AEBEB ≈ 13

𝐸𝑓𝑓𝑒𝑘𝑡 = 𝐴𝑛𝑡𝑎𝑙 𝑚𝑜𝑑𝑢𝑙𝑒𝑟 ∗ 𝑚𝑜𝑑𝑢𝑙𝑒𝑛𝑠 𝑒𝑓𝑓𝑒𝑘𝑡 = 13 ∗ 365𝑊 = 4,75 𝐾𝑊

- Husets övre tak:

Antal moduler som monteras på husets övre tak = I4JK51L3 /61/./0123 /61/ = C.AEBEC ≈ 11

𝐸𝑓𝑓𝑒𝑘𝑡 = 𝐴𝑛𝑡𝑎𝑙 𝑚𝑜𝑑𝑢𝑙𝑒𝑟 ∗ 𝑚𝑜𝑑𝑢𝑙𝑒𝑛𝑠 𝑒𝑓𝑓𝑒𝑘𝑡 = 11 ∗ 365𝑊 = 4,02 𝐾𝑊

- Husets nedre tak:

Antal moduler som monteras på garaget = ./0123 /61/

I4JK51L3 /61/= ]^ C.AEB≈ 21

𝐸𝑓𝑓𝑒𝑘𝑡 = 𝐴𝑛𝑡𝑎𝑙 𝑚𝑜𝑑𝑢𝑙𝑒𝑟 ∗ 𝑚𝑜𝑑𝑢𝑙𝑒𝑛𝑠 𝑒𝑓𝑓𝑒𝑘𝑡 = 21 ∗ 365𝑊 = 7,67 𝐾𝑊

- Anläggningens total effetk = 4,75+4,02+7,67 = 16,45 KW

Den årliga energiproduktionen beräknas med hjälp av simuleringsprogrammet PVGIS där matar man in lutning, effekt, Azimut, system förluster ca 14%, typ av modul och Radiation database till exempel ERA5.
