SOLAR RADIATION IN EUROPE

15/4/2015 www.ruukki.com | Pasi Turpeenniemi | PUBLIC 4

• Solar radiation carries energy, which is harnessed by the solar PV panels

• Solar radiation is about 1000 kWh/m2 in a year in Nordics and about 1200 kWh/m2 in Central Europe.

• Most radiation is available from March to September

SOLAR ELECTRICITY USAGE

15/4/2015 www.ruukki.com | Pasi Turpeenniemi | PUBLIC 5

Solar electricity yield • Solar PV power typically ~130…165Wp/m2* • Annual yield around 100-125kWh/m2

• 100m2 set produces ~10 000…12 500kWh/a

Electricity usage • Consumed by the building (if low feed-in tariff) • Fed into the grid (if good feed-in tariff)

Example -1000m2 warehouse: • Ventilation: 3000…6000kWh/a • Lighting: 16000…47000kWh/a

Average electricity consumption / building type

kWh/floor-m2,a

Shop Warehouse Industrial Sports

Ventilation 14-24 3-6 3-16 15

Lighting 47-95 16-47 31-47 36-55

*Wp=Watt-peak (nominal power of the PV module)
