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 20kWp 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!
SLIDE 8
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!
