Magpower, S.A.Concentrating Photovoltaic (CPV)

� The fundamental distinction of Concentrating Photovoltaics (CPV) is the amount of solar energy that reachs the cell

� The cell used by CPV are able to handle much more energy with much more efficiency than silicon cells

Parameter Flat panel Magpower cell

• Solar concentration 1x 800x

• Solar watts / cm2 0.1w 80w

• Cell area / m2 10,000 cm2 12,5 cm2

• Cell efficiency 15% 39%

• DC watts / m2 150w 390w

• Cell cost $250 $100

• $ / DC watt $1.66 $0.25

Cell CostExample of cost simulation for 1 m2

� Concentrated cells with the cost of around 15% of price of standard silicon

� Competitive cost of Wp with concentrated systems is reached with well designed components and very aggressive manufacturing processes.
