NorthSol Solar Power Plants in the north Kick Off Event: Sustainable Energy Systems 2050 Helsinki October 12th Research Leader Dr. Tobias Boström, Norut Narvik, Norway
Does it make sense to have solar energy power plants in the north? • Common conceptions and myths False! – Too little sunlight – Too expensive False! Lower temperatures give – Too cold higher efficiencies!
Irradiation on a horisontal surface (kWh/m 2 and year)
Irradiation on a 2 axis tracking surface (kWh/m 2 and year) Not dependent on the latitude, only the weather!
Annual Sun Hours – World Wide Country City Annual Sun Hours Britain London 1500 Germany Freiburg 1700 Sweden Piteå 2000 Australia Melbourne 2100 Italy Florence 2500 USA San Diego 3000
Simulated case study – Piteå • 2 axis tracking system – 0.09 € /kWh – Cost includes; panels, inverters, trackers, substructures, wiring, installation cost. No subsidies and no interest rate is included. – Output estimated for 25 years incl. degradation in power • 0.03 - 0.05 € /kWh (incl. subsidies)
Real case – Piteå • A 20kW p PV tracking power plant is being built now at PiteEnergi AB – Should be completed by December 2011 • Will be used for R&D and testing of – various tracking systems and PV technologies – Electrical quality / smart grids • Hopefully confirms the simulations and generates MW sized PV power plants within a 5 year horizon!
A bright future outlook for solar energy • Continuing fast reduction in PV production cost • Grid parity has already taken place • Installed capacity in 2020: 600 – 1,600 GW – To compare with today’s cumulative capacity of ~ 50 GW • In 2004, fossil fuels accounted for 83% of the world’s energy consumption • Solar Energy can and will change this number drastically!
